Answer:
56 mins
Step-by-step explanation:
Number of gallons of water in the pool per minute;
750 divided by 35 = 150/7
Let the time needed to fill a 1,200 gallon pool be t.
t x 150/7 = 1,200
t x 21.42857142857143... = 1,200
t = 1,200/21.42857142857143
t = 56 mins
Answer: Let length = 2x + 3
Let width = x
Area = 54 ft2
length × width = Area
x(2x + 3) = 54
2x2 + 3x = 54
2x2 + 3x - 54 = 0
(2x - 9)(x + 6) = 0
x = 9/2 and x = -6
x = 4.5 and x = -6
We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:
width = 4.5 ft
length = 2(4.5) + 3 = 9 + 3 = 12 ft
