3. A 24.000-gallon pool is being filled at a rate of 40 gallons per minute. At this rate, how many
minutes will it take to fill this pool 9 full?

Step-by-step explanation:

total gallon be filled in one minute =40 gallon

to fill half full you have to fill gallon =24000/2

=12000 gallon

Total time taken to fill 12000 gallon = 12000/40

=300 minutes.

or 5 hours

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

first one because it can't have a fraction in it
