Answer:

Chandra have 97 baseball cards.

Step-by-step explanation:

Given:

Chandra and Simone have 152 baseball cards together. Chandra's collection has 42 more baseball cards in it than Simone's collection.

Now, to find baseball cards Chandra have.

Let the baseball cards Simone's have be [tex]x.[/tex]

As, given  Chandra's collection has 42 more baseball cards in it than Simone's collection.

So.  Chandra's collection of cards is [tex]x+42.[/tex]

Together Chandra and Simone have baseball cards = 152.

According to question:

[tex]x+(x+42)=152[/tex]

[tex]x+x+42=152[/tex]

[tex]2x+42=152[/tex]

Subtracting both sides by 42 we get:

[tex]2x=110[/tex]

Dividing both sides by 2 we get:

[tex]x=55.[/tex]

Thus, Simone's collection of cards = 55.

Now, to get the baseball cards Chandra have we substitute the value of [tex]x[/tex]:

[tex]x+42\\=55+42\\=97.[/tex]

Therefore, Chandra have 97 baseball cards.

Yo sup??

total number of cards that Chandra and Simone have =152

let number of cards that Simone have be x

then chandra will have 42+x

from the statement given to us we can say that

x+x+42=152

2x=110

x=55

therefore Simone has 55 cards and chandra has 97 cards

Step-by-step explanation:

The expression that we have to evaluate in this problem is:

[tex]7x^{-3}y^{-1}[/tex]

We have to evaluate this expression for:

x = -2

y = 4

We start by rewriting the expression by rewriting it using the following:

[tex]a^{-n}=\frac{1}{a^n}[/tex]

So the expression can be rewritten as

[tex]7x^{-3}y^{-1}=\frac{7}{x^3 y}[/tex]

Now we observe that:

[tex](-2)^3=(-2)(-2)(-2)=-8[/tex]

Therefore, by substituting x = -2 and y = 4 into the expression, we find:

[tex]\frac{7}{(-2)^3\cdot 4}=\frac{7}{-8\cdot 4}=-\frac{7}{32}[/tex]

Answer: The value of a is 2 and the value of b is 3.

Step-by-step explanation:

Given : △CDE maps to △STU with the transformations (x, y) → (x − 2, y − 2) →(3x, 3y)

The first transformation is a translation ,so there will be no change in the length of the sides ∵  translation is a rigid motion.

The second transformation is a dilation ,so there will be a change in the length of the sides by scale factor of 3. ∵  dilation is not a rigid motion.

Basically , by combining both transformation:

Length of Side in  △STU = 3 x (Corresponding side in △CDE )

⇒ ST = 3CD   and TU  = 3 DE

If CD = a + 1, DE = 2a − 1, ST = 2b + 3 and TU = b + 6 , then

2b + 3=3(a + 1)  and b + 6 = 3(2a − 1)

⇒ 2b + 3=3a+3 and  b + 6 = 6a-3

⇒ 3a-2b=0        (i)   and b = 6a-9             (ii)

Put value of b from (ii) in (i)  , we get

3a-2(6a-9)=0

⇒ 3a-12a+18=0

⇒ -9a=-18

⇒ a= 2

Put value of a in (ii) , we get

b= 6(2)-9

=12-9=3

Hence, the value of a is 2 and the value of b is 3.

Step-by-step explanation:

The given vertices of the polygon are (-6,-2),(-5,1),(-1,4),(1,1),(5,3),(1,-2).

We need to find the area of the polygon.

Plot the given vertices and on a coordinate plane and draw the polygon. Divide the polygon in 4 parts as shown below.

Area of rectangle is

[tex]A=length\times width[/tex]

Area of triangle is

[tex]A=\dfrac{1}{2}\times base\times height[/tex]

Area of each figure is

[tex]A_1=\dfrac{1}{2}\times 1\times 3=1.5[/tex]

[tex]A_2=\dfrac{1}{2}\times 6\times 3=9[/tex]

[tex]A_3=\dfrac{1}{2}\times 4\times 3=6[/tex]

[tex]A_4=6\times 3=18[/tex]

Area of polygon is

[tex]A=A_1+A_2+A_3+A_4[/tex]

[tex]A=1.5+9+6+18=34.5[/tex]

The area of polygon is 34.5 units².

Therefore, the correct option is B.

We set up the equation (70+64+83+x)/4=75

Hope this helped!

Answer: she must score 83% on her 4th test if she wants to get a final average of 75%

Step-by-step explanation:

The formula for determining average is expressed as.

Average = sum of the score/ number of tests.

Sara got a 70%, 64%, and 83% on her first three tests. Her former average would be

(70 + 64 + 83) 217/3 = 72.3℅

Let x represent the score that she needs to get on her 4th test if she wants to get a final average of 75%.

Therefore,

(x + 217)/4 = 75

Cross multiplying by 4, it becomes

x + 217 = 300

x = 300 - 217

x = 83%

After the expression has been evaluated, looking at the main value of 8! − 6!, it becomes  39,600. Therefore 8! − 6! = 39,600.

To evaluate the expression 8!−6!, we first need to determine the value of 8! and the value of 6!, and then subtract the two results.

8! (read as "8 factorial") means:

8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 40,320

6! (read as "6 factorial") means:

6 × 5 × 4 × 3 × 2 × 1 = 720

subtract 6! from 8!:

8!−6! = 40,320 − 720 = 39,600

Therefore 8! − 6! = 39,600.

Answer: You loss is 65bucks.

Step-by-step explanation:

First, you win 25 bucks.

Next, the past 10 weeks 50 bucks.

For 10 weeks, you lost 2 bucks everyday:

10 × 7= 70days × 2= 140bucks.

In total you won) 25 + 50= 75 bucks.

You dropped 140bucks in total.

140- 75= 65 bucks.

Therefore, You lost 65bucks.

This question deals with Mathematics, specifically the concept of profit and loss. Despite winning a total of $75 over 10 weeks at the slots, you lose $2 everyday, totaling to $140 in losses over the ten weeks. Hence, you end up with a net loss of $65.

The subject of this question is related to Mathematics and more specifically on the concept of profit and loss. Here you have won a total of $75 over 10 weeks, but each day you play slot machines you lose $2. Given that a week has 7 days, you’ve lost $2 * 7 days/week * 10 weeks = $140 over the course of 10 weeks. So, despite seeming to 'win' at the slot machine, when we subtract the total loss from total gain, $75 - $140, we find that you've actually ended up with a net loss of $65.

Explanation:

A yard is a larger unit of measure than an inch, so it takes fewer yards to equal the distance of a larger number of inches.

__

As it happens, 1 yard is exactly the same as 36 inches (by definition). So the measurement that is 36 inches will be a measurement that is 1 yard.

Final answer:

Josh's desk appeared to have different measurements because of the change in units from inches to yards; 1 yard is equal to 36 inches, so the desk's height didn't actually decrease.

Explanation:

The question seems to contain a typo. Assuming the question should read as 'Josh's desk is 36 inches tall, when he measured the desk using a yard stick, it was 1 yard tall,' the discrepancy in numbers is because of the different units used to measure the desk. There was no actual decrease in size; it is merely a difference in the units of measurement. Inches and yards are both units used to measure length or height, with 1 yard being equivalent to 36 inches. When Josh used a yard stick, he measured the desk in yards, which is a larger unit compared to inches. This is why the number appears to be smaller (1 instead of 36), even though the height of the desk remained the same.

Answer:

595 Trout

Step-by-step explanation:

90 - 45 = 45

450 + 45 = 495

The estimated number of trout in the lake is 495 trouts.

The total number of trouts in the lakes that were initially tagged is added with the number of untagged trout that are caught afterward to find the total number of trout in the lake.

It is given that 450 trout were initially caught and tagged by a conservationist and were later released into the lake.

Therefore the total number of tagged trout = 450

Later, when the trout are caught again, we notice that 90 are caught and of those 90 trout, 45 have been tagged. This means that there are 45 untagged trout.

Therefore, total number of untagged trout = 90 - 45

= 45

Therefore, the total number of trout in the lake = 450 + 45

= 495

Thus, we have found that the estimated number of trout in the lake is 495 trouts.

The space left inside the tree is 300 cubic feet.

David and Karen have to paint 275 square feet on the outside.

Explanation:

It is given that the length of the tree house is 7.5 feet

The width of the tree house is 8 feet

The height of the tree house is 5 feet

The tree house is in the shape of a rectangular prism.

The volume of the rectangular prism is given by

[tex]\text {Volume}=\text {length } \times \text {width} \times \text {height}[/tex]

Substituting the values, we have,

[tex]Volume$=7.5 \times 8 \times 5$\\Volume $=300$[/tex]

Thus, the volume of the rectangular prism is 300 cubic feet

Hence, the space left inside the tree is 300 cubic feet.

The area they have to paint on the outside can be determined using the formula for surface area of the prism .

[tex]Area=2(w l+h l+h w)[/tex]

Substituting the values, we get,

[tex]Area=2[(8*7.5)+(5*7.5)+(5*8)][/tex]

Answer:

[tex]C(x) = 45x + 75\\\text{where x is the width of rectangular pen}[/tex]

Step-by-step explanation:

We are given the following in the question:

The length of the pen will be 5 feet more than twice as long as the width of the pen.

Let y be the length and x be the width. Thus, we can write:

[tex]y = 2x +5[/tex]

Fencing = Perimeter of rectangular pen

[tex]\text{Perimeter of rectangle} = 2(\text{length} + \text{width})\\ P = 2(y+x)\\P=2(2x+5+x)\\P= 2(3x+5)\\P = (6x + 10)\text{ feet}[/tex]

The cost of the pen will be $7.50 per foot of fencing.

Total Cost of fencing =

[tex]\text{Cost of fencing}\times \text{Perimeter}\\C(x) = 7.50\times (6x+10)\\C(x) = 45x + 75\\\text{where x is the width of rectangular pen}[/tex]

is the required cost function.

Final answer:

The cost function for fencing a rectangular pen, given the width x and a cost of $7.50 per foot, is c(x) = 45x + 75, representing the total cost as a function of the width x.

Explanation:

The student is asking for a function that represents the cost of fencing a rectangular pen when the width is given. Let x be the width of the pen. The length of the pen, according to the problem, is 5 feet more than twice the width, so it can be expressed as 2x + 5 feet.

The cost of the fencing is $7.50 per foot. To find the total cost of the pen, we have to calculate the perimeter of the rectangular pen, which is 2 times the width plus 2 times the length. Hence, the perimeter P(x) can be represented as P(x) = 2x + 2(2x+5).

Multiplying through and simplifying gives us the cost function c(x) = 7.50 * P(x). Therefore, c(x) = 7.50 * (2x + 2(2x + 5)) = 7.50 * (6x + 10) = 45x + 75. This function represents the cost of fencing the pen as a function of its width x.

The constant of proportionality, which is the cost per pair of jeans, is found by dividing the total cost by the number of pairs. For Alyssa's purchase of 3 pairs of jeans for $92.31, the constant of proportionality is $30.77 per pair.

To determine the constant of proportionality for the jeans Alyssa bought, we need to divide the total cost by the number of pairs of jeans she purchased. Since Alyssa bought 3 pairs of jeans for $92.31, we calculate the constant of proportionality as follows:

Therefore, the constant of proportionality is $30.77 per pair of jeans.

Final answer:

The constant of proportionality, or the cost per pair of blue jeans, is $30.77 calculated by dividing the total cost of $92.31 by the number of blue jeans, which is 3.

Explanation:

The student has asked how to find the constant of proportionality, which in this context is the cost per pair of blue jeans when buying multiple pairs. If Alyssa bought 3 pairs of blue jeans for a total of $92.31 on tax free weekend, we can calculate the cost per pair by dividing the total cost by the number of pairs. The constant of proportionality would be: $92.31 / 3 = $30.77 per pair of jeans.

Answer: Polaris would appear at [tex]26\°[/tex] latitude

Step-by-step explanation:

Let's begin by explaining that Latitude is the angular distance between the Earth's equator, and a specific point on the planet. It is measured in degrees and is represented according to the hemisphere in which the point is located, which can be north or south latitude.  

In this sense, latitude [tex]0\°[/tex] refers to the equatorial line that divides the Earth in two hemispheres (North and South), and Miami's latitude [tex]26\°[/tex] refers to the Northern hemisphere.

On the other hand, talking about the North Star (also known as Polaris); if we were just in the North Pole (latitude [tex]90\°[/tex]), Polaris would by exactly over our heads or the zenith ([tex]90\°[/tex] over the horizon), but as we go until latitude [tex]26\°[/tex], Polaris altitude will be approximately at that same angle over the horizon.

Hence, from an observer located in Miami, Polaris would appear at [tex]26\°[/tex] N.

In Miami, with a latitude of 26° N, the North Star appears at an altitude of 26° above the horizon. As you move southward, it appears lower; when you travel north, it appears higher. Precise navigation also considers the slight angular difference between Polaris and the true celestial pole.

In Miami, Florida, which has a latitude of 26° N, the North Star, or north celestial pole, would appear at an altitude of 26° above the northern horizon. This is because the altitude of the North Star above the horizon is roughly equivalent to the latitude of the observer's location in the Northern Hemisphere. Therefore, as one drives southward from Miami to a city at a lower latitude, the North Star would appear lower in the sky. Conversely, driving northward would make the North Star appear higher.

It's important to note that due to the Earth's curvature, as you move southward from Miami, both the North Star and the southern sky would appear to sink, while the opposite would occur as you move northward. If you were to reach the equator, the North Star would align with the northern horizon, and it would not be visible from latitudes south of the equator. For precision in navigation or astronomy, one must also account for the small angular distance between Polaris and the true north celestial pole.

Answer:

[tex]7\frac{29}{36}\ hours[/tex]

Step-by-step explanation:

Given:

Time spent on Monday (M) = [tex]4\frac{1}{4}\ hours[/tex]

Time spent on Tuesday (T) = [tex]3\frac{5}{9}\ hours[/tex]

Now, the total combined time spent on study is equal to the sum of the times spent on Monday and Tuesday.

So, we need to add both the times to get the combined time spent on studying.

The combined study time is given as:

Total time spent = Time spent on Monday + Time spent on Tuesday

[tex]Total\ time=4\frac{1}{4}+3\frac{5}{9}\\\\Total\ time = \frac{4\times 4+1}{4}+\frac{3\times 9+5}{9}\\\\Total\ time = \frac{17}{4}+\frac{32}{9}\\\\\textrm{Taking LCD of 9 and 4 as 36, we get:}\\\\Total\ time = \frac{17\times 9}{4\times 9}+\frac{32\times 4}{9\times 4}\\\\Total\ time = \frac{153}{36}+\frac{128}{36}\\\\\textrm{Since the denominators are same, we add the numerators.}\\\\Total\ time = \frac{153+128}{36}\\\\Total\ time = \frac{281}{36}\ hours[/tex]

Divide 281 by 36. The quotient is the whole number part, the remainder is the numerator part and the denominator remains the same.

So, on dividing, we get 7 as quotient and 29 as remainder. So, converting to mixed fractions, we get:

[tex]Total\ time = 7\frac{29}{36}\ hours[/tex]

Therefore, the  the combined time he spent studying is [tex]7\frac{29}{36}\ hours[/tex]

Answer: 1) R = {(a, a), (а,b), (b, a), (b, b), (с, с), (b, с), (с, b)}.

It is clearly not transitive since (a, b) ∈ R and (b, c) ∈ R whilst (a, c) ¢ R. On the other hand, it is reflexive since (x, x) ∈ R for all cases of x: x = a, x = b, and x = c. Likewise, it is symmetric since (а, b) ∈ R and (b, а) ∈ R and (b, с) ∈ R and (c, b) ∈ R.

2) Let S=Z and define R = {(x,y) |x and y have the same parity}

i.e., x and y are either both even or both odd.

The parity relation is an equivalence relation.

a. For any x ∈ Z, x has the same parity as itself, so (x,x) ∈ R.

b. If (x,y) ∈ R, x and y have the same parity, so (y,x) ∈ R.

c. If (x.y) ∈ R, and (y,z) ∈ R, then x and z have the same parity as y, so they have the same parity as each other (if y is odd, both x and z are odd; if y is even, both x and z are even), thus (x,z)∈ R.

3) A reflexive relation is a serial relation but the converse is not true. So, for number 3, a relation that is reflexive but not transitive would also be serial but not transitive, so the relation provided in (1) satisfies this condition.

Step-by-step explanation:

1) By definition,

a) R, a relation in a set X, is reflexive if and only if ∀x∈X, xRx ---> xRx.

That is, x works at the same place of x.

b) R is symmetric if and only if ∀x,y ∈ X, xRy ---> yRx

That is if x works at the same place y, then y works at the same place for x.

c) R is transitive if and only if ∀x,y,z ∈ X, xRy∧yRz ---> xRz

That is, if x works at the same place for y and y works at the same place for z, then x works at the same place for z.

2) An equivalence relation on a set S, is a relation on S which is reflexive, symmetric and transitive.

3) A reflexive relation is a serial relation but the converse is not true. So, for number 3, a relation that is reflexive but not transitive would also be serial and not transitive.

He earns $10 per hour babysitting his neighbors children. This means that the amount that he earns, babysitting his neighbors children for x hours would be

10x

He earns $12 per hour working at the other job. This means that the amount that he earns, working at the other job for y hours would be

The provided frequency distribution is:

Speed Cars

30-39 4

40-49 19

50-59 50

60-69 15

70-79 12

The formula to compute the mean for the grouped data is:

[tex]\bar{X} =\frac{\sum(mf)}{\sum(f)}[/tex]

Here, m is mid point and f is frequency.

The mean speed can be computed as:

Thus, the mean speed is 55.7 mph.

To find the mean of data from a frequency table, multiply each speed by its frequency, sum those products, and then divide by the total number of items. This produces a weighted average that reflects the frequency of each speed value in the dataset.

To calculate the mean from a frequency table, we should multiply each speed by its frequency to get the 'combined speed' for each group. Add those combined speeds together, then divide by the total number of cars (or the sum of the frequencies).

For example, suppose we had 5 cars with a speed of 60 mph and 10 cars with a speed of 70 mph. We multiply each speed by its frequency (5*60 + 10*70), then sum these values to get the total combined speed. Divide this total combined speed by the total number of cars (5 + 10) to get the mean speed.

This method averages out the impact of each speed, weighted by how frequently each occurs in the dataset.

We know that the Principal amount received by Jim is $2000, while the interest that Jim needs to pay is 3% quarterly, therefore, he needs to pay the interest 4 times a year. Thus, the value of n is 4.

Now, we know all the values therefore, substitute the values in the formula of compound interest,

[tex]A = P(1+ \dfrac{r}{n})^{nt}[/tex]

[tex]A = 2000(1+ \dfrac{3}{4})^{4 \times 4}\\\\A = \$2,253.98[/tex]

Hence, the interest that is needed to be paid by Jim in the 4 years of tenure is $2253.98.

Answer:

Step-by-step explanation:

Triangle BCZ is a right angle triangle. Triangle BCU is also a right angle triangle. Side BU is common to both triangles.

To determine m∠ZBC, we would apply the tangent trigonometric ratio.

Tan θ = opposite side/adjacent side. Therefore,

Tan B = 8/6 = 1.33

m∠ZBC = Tan^-1(1.33) = 53.06

m∠UBC = m∠ZBC/2 = 26.53

To determine CU, we would apply

the tangent trigonometric ratio.

Therefore,

Tan 26.53 = CU/6

CU = 6Tan26.53

CU = 6 × 0.4992

CU = 2.9952

The 6th value in a sequence is -26.

Step-by-step explanation:

an = -2n-14

⇒ a6 = -2(6)-14

⇒ a6 = -12-14

⇒ a6 = -26

∴ The 6th value in a sequence is -26.

Answer:

6 baseball games remain in the season.

Step-by-step explanation:

Let the number of baseball games remaining be 'x'.

Given:

Number of innings in 1 baseball game = 9

Number of innings to be played at home = 45

Number of innings to be played away from home = 45

Total number of innings played in the given season = 36

Now, total number of innings to be played in a season is equal to the sum of the innings played at home and away from home.

So, Total number of innings = 45 + 45 = 90 innings.

Now, out of 90 innings, 36 innings are already played.

So, the number of innings that remain is given as:

Innings remaining = Total innings - Innings already over

Innings remaining = 90 - 36 = 54

Now, 9 innings is equivalent to 1 baseball game.

So, 54 innings is equivalent to 'x' baseball games.

Setting up a proportion and solving by cross multiplication, we get:

[tex]\frac{9}{1}=\frac{54}{x}\\\\9x=54\\\\x=\frac{54}{9}=6[/tex]

Therefore, 6 baseball games remain in the season.

Answer:

Dimensions are 8 Inches by 14 inches by 20 inches

Step-by-step explanation:

The volume of the box is 2240. This means:

lbh = 2240

Where b is the width.

Width is two inches less than twice the height

b = 2h - 2

length is 4 inches less than 3 times the height

l = 3h - 4

Substituting these parameters into the lbh equation will yield the following:

h * (3h - 4) * (2h - 2) = 2240

h[6h^2-14h+8] = 2240

6h^3 -14h^2 + 8h - 2240= 0

Solving this cubic equation will yield one of the values to be 8. The other two values are complex numbers.

b = 2h - 2

l = 3h - 4

b = 2(8) - 2 = 14

l = 3(8) - 4 = 20

By first calculating the Garcia family's travel rate of 409 miles per day, we can estimate it will take them approximately 9 days to travel from San Diego, California to Bar Harbor, Maine.

The subject of this question is Mathematics, and it involves understanding and applying the concept of rate – the speed at which something happens over a particular period of time. In this case, we have the Garcia family traveling from San Diego, California, to Bar Harbor, Maine. They have traveled 2,045 miles in 5 days.

To find out how long it will take them to travel the entire way, we first need to calculate the rate at which they are traveling. We do that by dividing the total distance they have traveled by the total number of days it took them to travel that distance: 2045 miles / 5 days = 409 miles per day.

The distance from San Diego to Bar Harbor is about 3,305 miles. So, if they continue to travel at a rate of 409 miles per day: 3305 miles / 409 miles per day = about 8.08 days. Since they can't travel a fraction of a day, we'll round that up to 9 days. So it will take them approximately 9 days to travel from San Diego to Bar Harbor at their current rate.

Final answer:

George will weigh 172 pounds after four years of college, gaining 0.25 pounds per month. If he continues this trend for 10 more years, he will weigh 202 pounds at his 10-year college reunion.

Explanation:

To calculate the weight gain of George after college and for the next 10 years, we can use simple arithmetic. George starts at 160 pounds and gains 0.25 pounds each month.

Weight After College

Four years of college is equivalent to 4 years × 12 months/year = 48 months. If he gains 0.25 pounds each month, then over 48 months he will have gained:

0.25 pounds/month × 48 months = 12 pounds.

So, after college, his weight will be:

160 pounds + 12 pounds = 172 pounds.

Weight After Next 10 Years

To calculate his weight after the next 10 years, which is 10 years × 12 months/year = 120 additional months, we do the following calculation:

0.25 pounds/month × 120 months = 30 pounds gain.

Adding this to his weight after college:

172 pounds + 30 pounds = 202 pounds.

Therefore, for his 10-year college reunion, George will weigh 202 pounds.
