Answer:

The pool can hold about 5755 US gallon of water

Step-by-step explanation:

From the illustration of the pool, we see the pool to be in cylindrical shape with 5 feet deep and has a radius of 7 feet.

Volume of a the pool = volume of a cylinder

Recall that volume of cylinder = πr²h

In this case

r = 7, h = 5, π = 3.14

Therefore:

Volume = πr²h

= 3.14 x 7² x 5

= 3.14 x 49 x 5

= 769.3ft³

How much water the pool can hold is

Since: 1 cubic foot = 7.481 US gallon of water

769.3ft³ = 769.3 * 7.481 US gallon of water

769.3ft³ = 5755.13 US gallon of water

The pool can hold about 5755 US gallon of

The sum of 3 times the value of x and 2 is equal to four less than five times the value of x. Which equation can be used to find
bonufazy [111]

The question has omitted  options but i will solve, so you will just check my answer from the options you have.

Answer: The equation  to find the value of x = 3x+ 2= 5x-4

The value of x= 3

Step-by-step explanation:

Step 1

The sum of 3 times the value of x and 2 is equal to four less than five times the value of x can be expressed as

3x+ 2= 5x-4

Step 2

Solving this equation  to find the value of x , we have that

3x+ 2= 5x-4

3x-5x= -4-2

-2x= -6

x= -6/-2

x=3
