If a pool holds 22,000 gallons, how long will it take to fill the pool at a rate of 400 gallons per minute, rounded off to the nearest minute?

A pool can fill 22,000 gallons in 55 minute.

Step-by-step explanation:

Given :  A pool holds 22,000 gallons and to fill the pool at a rate of 400 gallons per minute,

To find  :  how long will it take to fill the pool .

Solution : We have given that

A pool can fill 400 gallons = 1 minute.

A pool can fill 1 gallons =

A pool can fill 22,000 gallons =  .

A pool can fill 22,000 gallons = 55 minute.

Therefore, A pool can fill 22,000 gallons in 55 minute.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
