Achilds pool is in the shape of a rectangular prism with a height of 2 ft and a base that is 4ft wide by 5ft long

during the course of the summer, the childs pool needed to be filled 3 times

how many cubic feet of water were needed to fill the pool during the summer

120 cubic feet

Step-by-step explanation:

Dimensions of the rectangular prism shaped child's pool is:

Height = 2 ft

Width of base = 4 ft

Length = 5 ft

To find the volume of water to be filled in pool once, we need to find volume of the pool.

Volume of pool = cubic feet

where represents length of base, represents width of base and represents height of base.

Plugging in given values.

Volume of pool = cubic feet

Volume of pool = cubic feet

∴ To fill the pool once, we will require 40 cubic feet of water.

In summers the child's pool needed to be filled 3 times.

So, the volume of water filled in summers would be 3 times i.e = cubic feet (Answer)

inequality:

620-37.4p ≥ 450

the minimum amount of packages needed to be removed from the elevator is 5.

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
