Melanie drove a total of 500 miles over three days. To determine how many miles she drove each day, we divided total miles by total days. This gives us 166.67 miles or 166 2/3 miles as a mixed number.
Explanation:The subject of the provided question is related to simple division. Here, Melanie has traveled 500 miles in total over the course of three days, and she drove the same distance each day. Mathematically speaking, to find out how many miles Melanie drove each day, we need to divide the total distance by the number of days. Hence, we divide 500 miles by 3 days.
This comes out to be 166.67 miles, which is the decimal format of the distance traveled by Melanie each day. However, the question asks for the answer to be written as a mixed number. Therefore, 166.67 miles can be expressed as 166 2/3 miles per day, as a mixed number. This is calculated by expressing the decimal .67 as a fraction.

5. Write the equation in standard form using integers
(no fractions or decimals): = −2/3 − 1

your final equation in slope-intercept form.
7. Write an equation of
1. The slope of the line is 3.
2. The direct variation equation is y = 3x
3. The equation in slope-intercept form is:y = 4
4. The equation in slope-intercept form is y = 2/3x + 1.
5. The equation = −2/3 − 1
6. The equation of the parallel line is y = 5x - 11.
1. Slope of the line:
The slope (m) of the line passing through (-1, 2) and (0, 5) can be calculated using the formula:
m = (y2 - y1) / (x2 - x1)
m = (5 - 2) / (0 - (-1))
m = 3 / 1
m = 3
Therefore, the slope of the line is 3.
2. Direct variation equation:
Since y varies directly with x, we can write their relationship as y = kx, where k is the constant of proportionality. We can find k using the given information:
y = 15 when x = 5
15 = k * 5
k = 3
Therefore, the direct variation equation is y = 3x
When x = 9, y = 3 * 9 = 27.
3. Equation in slope-intercept form: First, calculate the slope using the same formula as in question 1:
m = (4 - 4) / (1 - (-3))
m = 0 / 4
m = 0
Since the slope is 0, the line is horizontal. The equation in slope-intercept form is:
y = 4 (constant y-intercept because it passes through (1, 4))
4. Equation in slope-intercept form using point-slope form:
The point-slope form equation is:
y - y1 = m(x - x1)
Plug in the given values:
y - (-1) = 2/3(x - (-3))
y + 1 = 2/3(x + 3)
3y + 3 = 2x + 6
3y = 2x + 3 (subtract 3 from both sides)
y = 2/3x + 1 (divide both sides by 3)
Therefore, the equation in slope-intercept form is y = 2/3x + 1.
5. Writing the equation in standard form:
The equation = −2/3 − 1 is already in standard form (ax + by = c), where a = -2/3, b = 0, and c = -1.
6. Equation of the parallel line:
Since the parallel line has the same slope (5) as the given line, its equation will be of the form y = 5x + b. To find b, plug the point (2, -1) into this equation:
-1 = 5(2) + b
-1 = 10 + b
b = -11
Therefore, the equation of the parallel line is y = 5x - 11.

Answer:
x = 5 sqrt(6)/3
y= 10 sqrt(6)/3
Step-by-step explanation:
We know sin 60 = opposite/hypotenuse
sin 60 = 5 sqrt(2) /y
Multiply each side by y
y sin 60 = 5 sqrt(2)
Divide each side by sin 60
y sin 60/ sin 60 = 5 sqrt(2)/ sin 60
y = 5 sqrt(2) / sin 60
y = 5 sqrt(2) / sqrt(3) /2)
y = 10 sqrt(2)/ sqrt(3)
You cannot leave a sqrt in the denominator
y= 10 sqrt(2)/ sqrt(3) * sqrt(3)/sqrt(3)
y= 10 sqrt(6)/3
tan 60 = oppositve/ adjacent
tan 60 = 5 sqrt(2)/ x
Multiply each side by x
x tan 60 = 5 sqrt(2)
Divide by tan 60
x = 5 sqrt(2)/tan 60
x =5 sqrt(2)/sqrt(3)
You cannot leave a sqrt in the denominator
x = 5 sqrt(2)/sqrt(3) * sqrt(3)/sqrt(3)
x = 5 sqrt(6)/3
Marquise has 200 meters of fencing to build a rectangular garden. The gardens area (in square meters) as a function of the gardens width w (in meters) is modeled by:
Answer: 2500 meters²
Step-by-step explanation:
Perimeter: 200 = 4w
⇒ 50 = w
Area = w²
= (50)²
= 2500
The width of 50 meters will produce the maximum garden area of the rectangle of 2500 square meters.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
The perimeter of the rectangle = 2( length + Width)
200 = 2( length + Width)
100 - w = L
The area of the rectangle = length × Width
= w(100 - w)
= (-w)²+ 100w
So, (-w)²+ 100w where, a = -1 and b = 100
w = -100/2(-1)
w = 50
The area of the rectangle = (-w)²+ 100w
= (-50)²+ 100(50)
= 2500
Thus, The width of 50 meters will produce the maximum garden area of the rectangle of 2500 square meters.

On a standardized test, a score of 82 falls exactly 1 standard deviation below the mean. If the standard deviation for the test is 4, what is the mean score for the test?
Answer:
The correct answer is 86.
Step-by-step explanation:
Because 82 is only one standard deviation below the mean, then to find the mean, only add 82 + 4 = 86
The mean score for the test is 86.
What do you mean by standard deviation?In statistics, Standard deviation is a measure of the variation of a set of values.
σ = standard deviation of population
N = number of observation of population
X = mean
μ = population mean
We are given that;
Score=82
Number of tests=4
Now,
We can substitute σ=4 and xi=82 into the formula. We also know that there is only one data point that satisfies this condition, so we can use N=1.
[tex]\mu = \frac{\sum_{i=1}^{N}(x_i - \mu)^2}{N\sigma^2} + \mu[/tex]
We get:
μ=(82−μ)^2/4^2 +μ
Simplifying and solving for μ, we get:
μ=86

The solution to the inequality is [tex]\(x > -17\).[/tex]
To solve the inequality [tex]\(\frac{5-2x}{-3} - 4 < -x\)[/tex], let's first find a common denominator and then combine the fractions:
[tex]\(\frac{5-2x}{-3} - 4 < -x\)[/tex]
Multiply each term by -3 to clear the fraction:
[tex]\(5 - 2x + 12 < -3x\)[/tex]
Combine like terms:
[tex]\(-2x + 17 < -3x\)[/tex]
Add [tex]\(2x\)[/tex] to each side:
[tex]\(17 < -x\)[/tex]
Multiply each side by -1 (remember to reverse the inequality when multiplying by a negative number):
[tex]\(-17 > x\)[/tex]
So, [tex]\(x > -17\).[/tex]
The value of x in the inequality [tex]\(\frac{5-2x}{-3} - 4 < -x\) is \(x \in \left(-\infty, -\frac{7}{5}\right)\).[/tex]
Step 1: Start with the given inequality:
[tex]\[\frac{5-2x}{-3} - 4 < -x\][/tex]
Step 2: Multiply both sides of the inequality by -3 to clear the fraction:

Tank A has a capacity of 9.5 gallons. 6 1\3 gallons of the tank"s water are poured out. How many gallons of water are left in the tank
Answer: Since 1/3 can't be turned into a decimal, change .5 into 1/2. In order to subtract, the fractions need a common denominator. The least common denominator is 6. So 1/3 turns into 2/6, and 1/2 turns into 3/6. Now you need to take 9 3/6 minus 6 2/6. The answer is 3 1/6 gallons of water.
Step-by-step explanation:
Final answer:
To find the remaining water in Tank A after pouring out 6 1/3 gallons, subtract 6.333 from the tank's total capacity of 9.5 gallons, which leaves 3.167 gallons remaining in the tank.
Explanation:
The question involves determining the remaining quantity of water in a tank after a certain volume has been removed, which is a basic subtraction problem in mathematics. To solve it, subtract the volume of water that was poured out from the total capacity of the tank.
Tank A capacity: 9.5 gallons
Volume of water poured out: 6 1/3 gallons
To perform the subtraction, we first need to convert 1/3 of a gallon into a decimal. A third of a gallon is approximately 0.333 gallons. Adding this to 6 gallons gives us 6.333 gallons.
Now, subtract the volume poured out from the tank's capacity:
9.5 gallons (capacity) - 6.333 gallons (poured out) = 3.167 gallons (remaining in the tank)
Therefore, 3.167 gallons of water are left in the tank.

What is the remainder R when the polynomial p(x) is divided by (x + 1)? Is (x + 1) a factor of p(x)? p(x) = -3x4 + 2x3 - x2 + 6
Answer:
(x+1) is a factor with remainder 0.
Step-by-step explanation:
We divide (x+1) into the polynomial [tex]-3x^4+2x^3-x^2+6[/tex] through long division or synthetic. We choose long division and look for what will multiply with (x+1) to make the polynomial [tex]-3x^4+2x^3-x^2+6[/tex] .
[tex](x+1)(-3x^3)=-3x^4-3x^3[/tex]
We subtract this from the original [tex]-3x^4-(-3x^4)+2x^3-(-3x^3)-x^2+6[/tex].
This leaves [tex]5x^3-x^2+6[/tex]. We repeat the step above.
[tex](x+1)(5x^2)=5x^3+5x^2[/tex].
We subtract this from [tex]5x^3-(5x^3)-x^2-(5x^2)+6=-6x^2+6[/tex]. We repeat the step above.
[tex](x+1)(-6x)=-6x^2-6x[/tex].
We subtract this from [tex]-6x^2-(-6x^2)+0x-(-6x)+6=6x+6[/tex]. We repeat the step above.
[tex](x+1)(6)=-6x+1[/tex].
We subtract this from [tex]6x-(6x)+6-(6)=0[/tex]. There is no remainder. This means (x+1) is a factor.

Answer:
c (0,-4)
Step-by-step explanation:
-5x+y = -4
4x - 4y =16
Solve the first equation for y since we are using substitution.
-5x+y = -4
Add 5x to each side
-5x+5x+y = -4+5x
y = 5x-4
Substitute this equation y = 5x-4 into the second equation.
4x -4(5x-4) = 16
Distribute the -4
4x - 4(5x) -4(-4) = 16
4x-20x +16 = 16
Combine like terms
-16x +16 =16
Subtract 16 from each side
-16x+16-16 = 16-16
-16x =0
Divide by -16
x=0
But we still need to find y
y = 5x-4
y = 5(0) -4
y = -4

Given a standard deck of playing cards, what is the probability of randomly selecting a card that is either red or a face card or both? (a standard deck of playing cards has 52 cards, divided equally between red cards and black cards. there are twelve face cards among these 52, which are also divided equally between red cards and black cards. no card may be both red and black.)
Answer: [tex]\bold{\dfrac{8}{13}}[/tex]
Step-by-step explanation:
Red or Face - duplicates (both red & face)
[tex]\dfrac{26}{52}[/tex] + [tex]\dfrac{12}{52}[/tex] - [tex]\dfrac{6}{52}[/tex]
= [tex]\dfrac{32}{52}[/tex]
= [tex]\dfrac{8}{13}[/tex] simplified
Final answer:
The probability of selecting a red or face card from a standard deck of cards is 8/13. This outcome is more likely than selecting a heart suit face card specifically, which has a probability of 3/52.
Explanation:
The problem can be solved by understanding that the deck has 26 red cards (hearts and diamonds) and 12 face cards (jacks, queens, and kings), with 6 face cards being red. The total number of unique choices that are either red cards or face cards is the number of red cards plus the number of black face cards. This avoids double-counting red face cards.
There are 26 red cards, but we need to exclude the 6 red face cards already counted, and add the 6 black face cards (from clubs and spades), giving us 26 + 6 = 32 unique cards that are either red or face cards. The probability, P, is then 32/52, which simplifies to 8/13.
To compare, the probability of drawing specifically a heart suit face card is 3/52 as there are only 3 face cards (jack, queen, and king) in the heart suit. Comparing probabilities, 8/13 is greater than 3/52, so it is more likely to draw a red or face card than a heart suit face card.
Evaluate the expression described below if the variable given is 9. Two times the difference of one-third of a number and three. A. –9 B. –3 C. 0 D. 12
Answer:
Option C is correct.
The answer for the given expression is 0.
Step-by-step explanation:
Given the statement: Two times the difference of one-third of a number and three. and also variable given is 9.
Let x be the variable or number.
"One-third of a number" means [tex]\frac{1}{3}x[/tex]
Also, "difference of one third of a number and three " means [tex]\frac{1}{3}x-3[/tex]
Now, "Two times the difference of one-third of a number and three" means [tex]2 \times (\frac{1}{3} x -3)[/tex]
Then, the expression for the given statement : [tex]2 \times (\frac{1}{3} x -3)[/tex]
Substitute the value of x =9 in above expression we have;
[tex]2 \times (\frac{1}{3}(9) -3)[/tex] = [tex]2 \times (3 -3)[/tex] = [tex]2 \times (0)[/tex] = 0
therefore, the answer for the given expression is, 0

Marta's annual salary increases by $2700 each year. Applying the recursive formula: f(n) = f(n-1) + 2700; f(4)=f(3)+2700=f(2)+2700+2700=f(1)+2700+2700+2700=f(0)+2700+2700+2700+2700=24900+4*2700=35500, we determine that Marta's salary in 4 years would be $35,500.
Explanation:The subject of the question involves recursion, or constructing a sequence of numbers in a specific way. In Marta's case, her salary can be calculated using a recursive formula that builds upon her previous salary. This formula relies on the concept of numerical patterns and can be represented as follows: f(n) = f(n-1) + 2700; where f(n) is Marta's salary after n years and f(n-1) is her salary the previous year.
At the start, Marta's salary is 24,900, which serves as the base case for our recursive function. Therefore, her income increases by $2700 each year. To get Marta's salary in 4 years, we would use the recursive formula: f(4) = f(3) + 2700 = f(2) + 2700 + 2700 = f(1) + 2700 + 2700 + 2700 = f(0) + 2700 + 2700 + 2700 + 2700 = 24,900 + 4*2700 = 35,500. So, Marta's salary is $35,500 after 4 years.
Therefore, the correct option among choices provided is none from the given options.

A.1/3 B.1/6 C.1/12 D.1/36 2.What is the number of possible outcomes if two marbles are picked out of a bag that contains three red marbles and three blue marbles? [Note: Order does not matter.] A) 2 B) 3 C) 4 D) 6
Answer:
1. The correct answer is D) 1/36
Step-by-step explanation:
WE can tell this because the chance of rolling either is 1/6. To find the total probability we multiply those together.
1/6 * 1/6 = 1/36

Quadrilateral OPQR is inscribed inside a circle as shown below. What is the measure of angle Q? You must show all work and calculations to receive credit.
Circle N is shown with an inscribed quadrilateral labeled OPQR. O is labeled 2x degrees. P is labeled y degrees. Q is labeled 2x plus 4 degrees. R is labeled 3y plus 8 degrees.
Answer:
m<Q = 92 degrees
Step-by-step explanation:
Opposite angles of a quadrilateral inscribed in a circle are supplementary.
Angles O and Q are opposite angles, so they are supplementary, so their measures add up to 180 degrees.
m<O + m<Q = 180
2x + 2x + 4 = 180
4x + 4 = 180
4x = 176
x = 44
m<Q = 2x + 4 = 2(44) + 4 = 92
Answer:
Q =92
Step-by-step explanation:
Since the quadrilateral is inscribed in a circle, the opposite angles add to 180 degrees.
<O + <Q = 180
2x+ 2x+4 = 180
4x+4 =180
Subtract 4 from each side
4x= 180-4
4x= 176
Divide by 4
x = 44
Q = 2x+4
Q = 2(44)+4
Q = 88+4
Q = 92
Richie the Racoon and his family are all going to a family reunion! At the reunion there is a grandmother, a grandfather, two mothers, two fathers, four children, three grandchildren, one brother, two sisters, two sons, two daughters, a mother-in-law, a father-in-law and a daughter-in-law. How many people came to Richie's family reunion?
Answer:
Seven
Step-by-step explanation:
We have the following list of people coming to the reunion,
A grandmother = 1
A grandfather = 2
Two mothers = 1 and 3
Two fathers = 2 and 4
i.e. Up until here there are total 4 people - Grandmother, Grandfather, Mother, Father ( 1, 2, 3, 4)
Four children = 4, 6, 7, 8
Three grandchildren = 6, 7, 8
One brother = 6
Two sisters = 7, 8
Two sons = 4, 6
Two daughters = 7, 8
Therefore, in addition to the four people above, one of the child will be the father and so there are 3 grandchildren.
So, number of people added in this step is 3 and total number of people up until here becomes 7.
A mother-in-law = 1
A father-in-law = 2
A daughter-in-law = 3
So, no new family member is added in this step.
Hence, total number of family members coming to reunion are 7 namely Grandmother, Grandfather, Mother, Father, Three children.
The table shows the input and output of a function Table(input:3,4,6,11. Output:5,7,11,21)
(a) Explain what makes this set of data a function.
(B) what could cause this set of data to not be a function? Provide a specific example to support your statement and explain throughly.
(c) write an equation, in function nation, that would fit in the inputs and outputs in the table. Show your work that proves your equation is true for the given data.
Answer:
(A)This set of data is a function because every input has an output.
(B) This set of data would not be a function if two inputs had the same output, for example, if the inputs were 3,4,4,11 and the outputs were 5,7,11,21 then the data set would not be a function because for input 4 it has two different outputs.

Triangle GHJ has the exterior angles shown below.
Answer options:
-2.7
-5.8
-12
-29
Exterior angles of triangles = 360°.
So by definition:
[tex]9x + 6 + 10x - 1 + 10x + 7 = 360\\29x + 12 = 360\\29x = 348\\x = 12[/tex]
The value of x is 12.
Answer: 12
Step-by-step explanation:
We know that the sum exterior angles of a polygons is [tex]360^{\circ}[/tex].
Therefore,according to the given picture , we have
[tex]\angle{GHJ}+\angle{HJG}+\angle{JGH}=360^{\circ}\\\\\Rightarrow\ (9x+6)^{\circ}+(10x-1)^{\circ}+(10x+7)^{\circ}=360\\\\\Rightarrow\ 9x+6+10x-1+10x+7=360\\\\\Rightarrow\ 29x+12=360\\\\\Rightarrow\ 29x=348\\\\\Rightarrow\ x=\dfrac{348}{29}\\\\\Rightarrow\ x =12[/tex]
Hence, the value of x = 12
