The perimeter of a square is 80-64y units. Which expression can be used to show the side length of one side of the square?
A. 16(5-4y): Each side measures 5-4y units.
B. 16y(5-4): Each side measures 5-4 units.
C. 4(20-16y): Each side measures 20-16y units.
D. 4y(20-16): Each side measures 20-16 units.

Answer:

Brook is faster.

Step-by-step explanation:

1 hour=60 minutes

2 hours=2*60=120 minutes

-------------

7 miles in 30 minutes vs 25 miles in 120 minutes

7/30=0.233...mile per minute

25/120=0.20833...mile per minute

Brook is faster than Joshua.

To determine which person is faster, we can compare their average speeds.

Average speed is calculated by dividing the total distance traveled by the total time taken.

For Brook, she traveled 7 miles in 30 minutes, so her average speed is:

7 miles ÷ 30 minutes = 0.2333 miles per minute.

For Joshua, he traveled 25 miles in 2 hours, which is equivalent to 120 minutes. So his average speed is:

25 miles ÷ 120 minutes = 0.2083 miles per minute.

Therefore, Brook is faster than Joshua as her average speed is higher.

               = 6x - 0.5x - 50 = 5.5x - 50

Answer:

a) [tex]y=m+6.75[/tex] where [tex]m[/tex] is the number of comic books

b) Case B has better deal  

Step-by-step explanation:

a)

Thus, this is in the form of :

[tex]y=m*x+b[/tex]

Given :

subtracting both ,

The cost of one comic book is $1;

substituting in the first equation ,

[tex]12.75=6+b\\b=6.75;[/tex]

The equation is :

[tex]y=m+6.75[/tex]

b)

Since the shop sells poster with a comic book , initial value is the cost of one comic book plus one poster.

[tex]7.99=x+b\\x=1;[/tex] --since its similar.

In case of a. , The cost of one book plus poster = $1+6.75=$7.75

which is lesser than $7.99 .

Thus case B has the best deal.  

Answer:

6.7√2 in ≈ 9.48 in

Step-by-step explanation:

First, use the area of the square to find the side length.

A = s²

44.89 in² = s²

s = 6.7 in

The diagonal of a square divides it into 45-45-90 triangles.  You can use Pythagorean theorem to find the length of the diagonal.

c² = a² + b²

c² = (6.7 in)² + (6.7 in)²

c = 6.7√2 in

c ≈ 9.48 in

Answer: 6.7√2

Step-by-step explanation: Let's start this problem by drawing a picture of a square with a diagonal of length x.

Now to find the length of the diagonal, let's first find the length of a side of the square. To find the length of a side, remember that the formula for the area of a square is S² and since we know that the area of the given square is 44.89 inches, we can set up the equation 44.89 = S².

Square rooting both sides, we have 6.7 = S so we can give the side of our square a length of 6.7. Now to find the value of x, it's important to understand that the diagonal of a square creates 45° 45° 90° triangles and in a 45° 45° 90° triangle, the hypotenuse = √2 × leg.

So we have x = 6.7√2.

So the length of the diagonal of the square is 6.7√2 inches.

Answer:

The correct answer is B. $310 at $2 per kilogram

Step-by-step explanation:

1. Let's find out the maximum profit Ms. Ortiz can make with a loaf of tomatoes:

function p(x)=–80x² + 320x – 10

For x = 1, price per kilogram of tomatoes would be: 4 - x = 3

–80x² + 320x – 10, replacing with x = 1

-80 * 1² + 320 * 1 - 10 = -80 + 320 - 10 = 230

For x = 2 price per kilogram of tomatoes would be: 4 - x = 2

–80x² + 320x – 10, replacing with x = 2

-80 * 2² + 320 * 2 - 10 = -320 + 640 - 10 = 310

For x = 3, price per kilogram of tomatoes would be: 4 - x = 1

–80x² + 320x – 10, replacing with x = 3

-80 * 3² + 320 * 3 - 10 = -720 + 960 - 10 = 230

The correct answer is B. $310 at $2 per kilogram

Answer:The correct answer is B.) $310 at $2 per kilogram

Answer:

Total Cost of Week = 81.20 Euros

Total Cost of Week (in dollars) = $102.31

Step-by-step explanation:

117 km per day

You drive 7 days

So,

Total miles driven = 117 * 7 = 819 km

Mileage is 42 miles per gallon. So how many gallons would it require to drive 819 km?

819/42 = 19.5 gallons

We know 1 gallons = 3.78 liters

So,

19.5 gallons would be:

19.5 * 3.78 = 73.82 liters

1.10 Euro PER LITER, so the total cost:

Total Cost of Week = 73.82 * 1.10 = 81.20 Euros

In dollars (1 euro = 1.26 dollars):

Total Cost of Week (in dollars) = 81.20 * 1.26 = $102.31

The cost on gas is approximately 7.2 euros

Data given;

If 1mi = 1.609km

And we cover 117km daily, let's convert this into miles

[tex]1mi=1.62km\\ x mi = 117km\\ x = 117/1.62\\ x = 72.2mi[/tex]

This shows that we cover a distance of 72.2 miles daily.

But the car consumes 1 gallon in 42 miles, let's calculate the gas required to cover 72.2 miles

[tex]42mi = 1g\\ 72.2mi =x\\ x = 72.2/42\\ x = 1.719[/tex]

The total gas consumed daily is approximately 1.72 gallons.

The cost of gas daily can be calculated from the data given but we have to convert the volume from gallon to liter

1L = 0.26 gallon

xL = 1.72 gallons

cross multiply this and solve for x

[tex]x = \frac{1*1.72}{0.26}\\ x = 6.6[/tex]

This shows that we consume 6.6L daily.

But we were given that the cost of 1 liter of gas is equal to 1.10 euros

1L = 1.10 euros

6.6L = x euros

[tex]x = \frac{1.1*6.6}{1}\\ x = 7.26[/tex]

The cost of gas daily is 7.26 euros or approximately 7.2 euros.

x = 5

Step-by-step explanation:

7x is a secant- secant angle and has measure equal to half the difference of the intercepted arcs, that is

7x = 0.5(22x + 10 - 50)

7x = 0.5(22x - 40) ← distribute

7x = 11x - 20 ( subtract 11x from both sides )

Step-by-step explanation:

Answer:

160/x = 4/3

x = (160/4)(3) = 40(3) = 120

Apples: 160 pounds

Grapes: 120 pounds

Blackberries: 160 pounds

The total weight of this truckload of fruit is 160 + 120 + 160 = 440 pounds.

To find the total weight of the truckload of fruit with apples weighing 160 pounds in a ratio of 4:3:4, calculate the total ratio parts and apply it to the weight of apples. The total weight of the fruit is 440 pounds.

The truck carries apples, grapes, and blackberries in the ratio of 4:3:4.

To find the total weight, you need to calculate the total ratio parts, which is 4 + 3 + 4 = 11 parts. Then, for apples alone, 4 parts represent 160 pounds, so each part is 160/4 = 40 pounds. The total weight of the truckload of fruit would be 11 parts * 40 pounds = 440 pounds.

3, 30, 20

Step-by-step explanation:

Start by determining the ratio of yellow to red paint. Use the column where both amounts are given:

yellow to red = 2 to 6 = 1 to 3

2 to 6 the same as 1 to 3 when reduced, by dividing both sides by 2.

This means yellow paint is a third of red paint. Backwards, red paint is three times yellow paint.

To go from yellow to red, do yellow X 3.

To go from red to yellow, do red ÷ 3.

Column 1:

1 X 3 = 3

Column 3:

10 X 3 = 30

Column 4:

Final answer:

To raise the fraction 1/5 to 15ths, multiply both the numerator and the denominator by 3 to get the equivalent fraction 3/15.

Explanation:

To raise the fraction 1/5 to 15ths, we need to find an equivalent fraction that has a denominator of 15. To do this, we need to find a number that we can multiply both the numerator and the denominator of 1/5 by to get a new fraction with a denominator of 15. Since 5 multiplied by 3 equals 15, we multiply both the numerator and the denominator of 1/5 by 3.

Thus, we have:

1/5 × 3/3 = 3/15

To raise the fraction 1/5 to 15ths, multiply both the numerator and the denominator by 3 to get the equivalent fraction 3/15.

The fraction 1/5 is equivalent to 3/15 when raised to 15ths.

Number of hamburgers bought is 23 and number of bags of fries bought is 14

Let "h" be the number of hamburgers bought

Let "f" be the number of bags of fries bought

Cost of one hamburger = $ 1.49

Cost of one bag of fries = $ 1.19

Given that Ben spent a total of 50.93

Thus we can frame a equation as:

number of hamburgers bought x Cost of one hamburger + number of bags of fries bought x Cost of one bag of fries = $ 50.93

[tex]h \times 1.49 + f \times 1.19 = 50.93[/tex]

1.49h + 1.19f = 50.93 ------ eqn 1

Also given that the number of hamburgers was five less than twice the amount of fries

number of hamburgers bought = 2(number of fries) - 5

h = 2f - 5  ---------- eqn 2

Let us solve eqn 1 and eqn 2 to find values of "h" and "f"

Substitute eqn 2 in eqn 1

1.49(2f - 5) + 1.19f = 50.93

2.98f - 7.45 + 1.19f = 50.93

4.17f = 50.93 + 7.45

4.17f = 58.38

[tex]f = \frac{58.38}{4.17}[/tex]

Substitute f = 14 in eqn 2

h = 2(14) - 5

h = 28 - 5 = 23

Summarizing the results:

number of hamburgers bought = h = 23

number of bags of fries bought = f = 14

The question doesn't require any specific probabilities, but I'm adding my own calculations to make it easier for you to solve your own problem

Answer:

Questions added and answered below

Step-by-step explanation:

Venn Diagram

When we have different sets, some of them belong only to one set, some belong to more than one, some don't belong to any of them. This situation can be graphically represented by the Venn Diagrams.

Let's analyze the data presented in the problem and fill up the numbers into our Venn Diagram. First, we must use the most relevant data: there are 60 people in both the choir and the band. This number must be in the common space between both sets in the diagram (center zone, purple).

We know there are 110 people in the choir, 60 of which were already placed in the intersection zone, so we must place 110-60=50 people into the blue zone, belonging to C but not to B.

We are also told that 240 people are in a band, 60 of which were already placed in the intersection zone, so we must place 240-60=180 people into the red zone, belonging to B but not to C.

Finally, we add the elements in all three zones to get all the people who are in the choir or in the band, and we get 50+60+180=290. Since we have 450 people in the school, there are 450-290=160 people who are not in the choir nor in the band.

The question doesn't ask for a particular probability, so I'm filling up that gap with some interesting probability calculations like

a) What is the probability of selecting at random one person who is in the band but not in the choir?

The answer is calculated as

[tex]\displaystyle P(A)=\frac{180}{450}=0.4[/tex]

b) What is the probability of randomly selecting one person who belongs only to one group?

We look for people who are in only one of the sets, they are 50+180=230 people, so the probability is

[tex]\displaystyle P(B)=\frac{230}{450}=0.51[/tex]

b) What is the probability of selecting at random one person who doesn't belong to the choir?

We must add the number of people outside of the set C, that is 180+160=340

[tex]\displaystyle P(C)=\frac{340}{450}=0.76[/tex]

Answer: 1/3

Step-by-step explanation: The ratio 12:36 can be written as the fraction 12/36. So, we simply put the 12 as the numerator of our fraction and put the 36 as the denominator of our fraction.

12/36 can be simplified by dividing the numerator and the denominator by the greatest common factor of 12 and 36 which is 12 and we get the fraction 1/3.

The fraction 1/3 still represents the ratio 1/3 even though we have written it in the form of a/b or fraction form.
