22,800-gallon swimming pool is being filled by four hoses. water flows through each hose at a rate of 300 gallons per hour. how many hours will it take to fill the pool?
a) 19 hours
b) 76 hours
c) 152 hours
d) 304 hours

The correct option is a.

Step-by-step explanation:

The capacity of swimming pool is 22,800.

Water flows through each hose at a rate of 300 gallons per hour.

The number of hoses is 4.

Water flows through 4 hoses in each hour is

So in each hour the water level in the swimming pool is increased by 1200 gallon.

In one hour 1200 gallon water can be filled in the pool, so the time taken by hoses to fill the swimming pool completely is

Therefore the correct option is a.

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
