Alina [70]

Answer:

C

Step-by-step explanation:

The rate of change here will be the difference in the number of tracks divided by the difference in the number of albums.

Let's pick two random rows (it doesn't matter which two because they will produce the same result): (2, 16) and (4, 32).

The rate of change is: $\frac{32-16}{4-2} =\frac{16}{2} =8$

The answer is thus C.

LeAnn is purchasing giftwrap for a box that measures 8 inches long, 6 inches wide, and 6 inches tall. Calculate the total area o

Pavel [41]

Let

L---------> the length side of the box

W--------> the width side of the box

H-------> the height of the box

we know that

$L=8\ in\\W=6\ in\\H=6\ in$

the surface area of the box is equal to

$S=2*area\ of\ the\ base+perimeter\ of\ the\ base*H$

Find the area of the base

$A=L*W=8*6=48\ in^{2}$

Find the perimeter of the base

$P=2*L+2*W=2*8+2*6=28\ in$

Find the surface area

$S=2*48+28*6$

$S=264\ in^{2}$

therefore

the answer is

the total area of the box that will be covered in gift wrap is $264\ in^{2}$

Kathi and Robert Hawn had a pottery stand at the annual Skippack Craft Fair. They sold some of their pottery at the original pri

grigory [225]

Answer:27 pieces were sold at the original price.

63 pieces were sold at the new price

Step-by-step explanation:

Let x represent the number of pieces of pottery that was sold at the original price.

Let y represent the number of pieces of pottery that was sold at the new price.

They sold some of their pottery at the original price of $9.50 for each piece. This means that the amount that they got from selling x pieces of pottery at the original price would be 9.5x

They later decreased the price of each piece by $2. This means that the new price was 9.5 - 2 = $7.5

This means that the amount that they got from selling x pieces of pottery at the new price would be 7.5y

If they sold all 90 pieces and took in $729, then the equations are

x + y = 90

9.5x + 7.5y = 729 - - - - - - - - - -1

Substituting x = 90 - y into equation 1, it becomes

9.5(90 - y) + 7.5y = 729

855 - 9.5y + 7.5y = 729

- 9.5y + 7.5y = 729 - 855

- 2y = - 126

y = - 126/- 2 = 63

Substituting y = 63 into x = 90 - y, it becomes
