Answer: The expression representing the amount of money spent is 5x+60 by Emily.

Step-by-step explanation:

Since we have given that

Let the cost price of per pair of sandals be 's'

Let the cost price of per pair of  boots be 's+30'.

Number of pairs of boots = 2

Number of pairs of sandals = 3

Total cost would be

2(s+30)+3s\\\\=2s+60+3s\\\\=5s+60

Hence, the expression representing the amount of money spent is 5x+60 by Emily.

The price of a swimming pool
Goryan [66]

Answer:

  • Sales\:\:Price=List\:\:Price-Discount
  • Sales price= $1167.25 List price=L Discount=19.5\%\:of\:L=0.195L
  • 1167.25=L-0.195L

Step-by-step explanation:

The percentage discount is 19.5\%

The discount is always given on the list price.

Sales\:\:Price=List\:\:Price-Discount

Let the list price be L, then

List price=L

Sales price= $1167.25

Discount=19.5\%\:of\:L=0.195L

We substitute into the equation to get:

1167.25=L-0.195L

1167.25=0.805L

Divide both sides by 0.805

\frac{1167.25}{0.805}=L

1450=L

The list price of the swimming pool is $1450

Tennis balls with a diameter of 2.5 in.are sold in cans of three. The can is a cylinder. What is the volume of the space in the
Alexxandr [17]

Using 3.14 for PI.

The radius of a ball and the can is half the diameter = 1.25

The height of the can is the height of 3 diameters = 7.5

Volume of one tennis ball:

4/3 x PI x 1.25^3 = 8.18 cubic inches.

Volume of 3 tennis balls: 3 x 8.18 = 24.54 cubic inches.

Volume of can:

PI x 1.25^2 x 7.5 = 36.80 cubic inches.

Space = 36.80 - 24.54 = 12.26 cubic inches.
