rs. Young is buying tshirts for her students in a class. There are 24 students in her class. Each student will pay $9.50 for their shirts. During the first week, 15 students paid. The remaining students paid the second week. How much money will be collected on the second week?

Answers

Answer:

The answer is $85.50

Step-by-step explanation:

You have to multiple the number of students that are paying on the second week, which is 9 by $9.50, then you'll get $85.50

WEEK ONE --

9.50 x 15 = $142.5 (15 out of 24 students)

--

WEEK TWO --

9 x 9.50 = $85.5 (9 out of 24 students)

--

$85.5 will be collected on the second week.

A recipe calls for 2/3 of cups of milk for 11 cookies. How many cups of milk are needed to make 165 cookies?

Answers

Answer:

10 cups of milk

Step-by-step explanation:

Make a proportion, where x is the number of cups of milk for 165 cookies:

[tex]\frac{2/3}{11}[/tex] = [tex]\frac{x}{165}[/tex]

Cross multiply and solve for x:

11x = 110

In the figure below, triangle ABC is similar to triangle PQR, as shown below.

What is the length of side PQ? (1 point)
a-33
b-34
c-35
d-36

Answers

Answer: 36

Step-by-step explanation:

As you can see, side AB is similar with side PQ.

Also, side BC is similar with side QR.

If you divide the length of side QR (34.5) by the length of side BC (11.5)

you get 3.

3 is the ratio that you will use to find the other side. The ratio of triangle ABC to  PQR is 1:3

Multiply the side of AB (12) by 3 and you will get 36.

The measure of side PQ in triangle PQR is 35 units. Therefore, option D is the correct answer.

What are similar triangles?

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

Given that, triangle ABC is similar to triangle PQR.

By similar triangles statement, we have

AB/PQ = BC/QR

12/PQ = 11.5/34.5

12×34.5=PQ×11.5

11.5PQ=414

PQ=414/11.5

PQ=36

Therefore, option D is the correct answer.

Write an equation in​ point-slope form of the line that passes through the given​ points, then write the equation in​ slope-intercept form. ​(​-6,6), (6,2)

Answers

Point-Slope form = y-y1=m(x-x1)

Y-6 = -1/3 (x+6)

Slope-intercept form = Y=mx+b

y = -1/3 + 4

The equation of line is y= -2/3x + 2.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

Points: (​-6,6), (6,2)

Slope= (-2 - 6)/( 6 -(-6))

slope= -8 / 12

slope= -2/3

Now, using slope intercept form

y-b = m(x- a)

y- 6 = -2/3( x + 6)

y -6 = -2/3x - 4

y= -2/3x + 2

Hence, the equation of line is y= -2/3x + 2.

The directions on a sewing pattern say to buy an extra 12.5% of fabric to account for error. Sam needs 2.75 yards of fabric to make a shirt, so he buys 2.4 yards. Choose the correct statement.

A.Sam bought the correct amount of fabric because he bought what was suggested.

B.Sam bought the correct amount of fabric because he needs less than 2.4 yards.

C.Sam did not buy the correct amount of fabric because he needs less than 2.4 yards.

D.Sam did not buy the correct amount of fabric because he should have bought 3.09 yards​

Answers

Answer:

Sam should have bought 3.09 yards of fabric instead of 2.4 yards

So, Option D is correct.

Step-by-step explanation:

Total fabric needed by Sam = 2.75

According to directions on a sewing pattern they say to buy an extra 12.5%

So, extra fabric would be: 12.5% of 2.75

Solving

[tex]12.5\% \ of \ 2.75\\=\frac{12.5}{100}\times 2.75 \\=0.343[/tex]

Now adding 0.343 into 2.75 to get extra fabric quantity:

2.75+0.343

=3.09

Therefore Sam should have bought 3.09 yards of fabric instead of 2.4 yards

So, Option D is correct.

10. What are the break-even points of the profit function (the values of x where profit equals 0)? Use the quadratic formula. (4 points: 2 points for each x-value)

Answers

Answer:

r = 50000

P (r) = 0.7r - 35000

Step-by-step explanation:

Given cost function is

C (r) = 0.85r + 35000

and revenue function is

R (r) = 1.55r

At break even point, revenue is equal to cost

R(x)= C(x)

1.55r = 0.85r+35000

Subtract 0.85 from both sides

0.7r = 35000

divide by 0.7 on both sides

r = 50000

Profit function

P(x)= R(x)- C(x)

P(r) = 1.55r - (0.85r+35000)

P(r) = 1.55r - 0.85r - 35000

P(r) = 0.7r - 35000

Clare knows that Priya has a bunch of nickels and dimes in her pocket and that the total amount is $1.25. Find one possibility for the number of nickels and number of dimes that could be in Priya's pocket. Write an equation that describes the relationship between the number of dimes and the number of nickels in Priya's pocket. Explain what the point (13,6) means in this situation. Is the point (13,6) a solution to the equation you wrote? Explain your reasoning.

Answers

Answer:5x + 10y = 125

Step-by-step explanation

Number of nickel = x

Number of dime = y

Nickel = 5 cent

Dime = 10 cent

Total value = $1.25

Total value should be converted to cent since both dime and nickel are both in cent

= $1.25 * 100 = 125 cents

Therefore,

5x + 10y = 125 cents
