Question

25 POINTS TO ANSWER!! THIS IS URGENT! ⚠️⚠️⚠️⚠️ the public swimming pool is being emptied by a pump, W in gallons at any time, T in hours. answer the following questions using the equation W=9,000-250t.

after 11 hours how much water is led in the pool?

how long will it take to empty the pool?

Answer 1

To find how much is in the pull in 11 hours, we can plug 11 in for t
W = 9000 -250(11)
W = 9000 - 2750
W = 6250 gallons
To find how long it will take to empty the pool, we can set the gallons equal to 0
0 = 9000 - 250t
To solve for t, we will first subtract both sides by 9000
-9000 = -250t
We will then divide both sides by -250
t = 36 hours
