So,
120 gal./min.
There are 4 qt. in a gal.
Multiply 120 by 4.
120(4) = 480 qt.
The pool is being drained at a rate of 480 qt./min.
Now, since there are 60 min. in an hr., multiply 480 by 60.
480(60) = 28,800 qt./hr.
The pool is being drained at a rate of 28,800 qt./hr. (quarts per hour)
Answer:
5
Step-by-step explanation:
(8+4+5+4+9+0) /6 = 5
First you simplify the square root of -8, which is approximately -2.83. Subtract -2 by the square root of -8, and you'll get -4.83. Divide -4.83 by 2, and the answer should be -2.415 or -2.42. I'm not sure about this answer though.
Answer:
Step-by-step explanation:
5x + 4y = 20
You need to express y in terms of x.
isolate the y term
4y = -5x + 20
divide both sides by the coefficient of y
y = (-5/4)x + 5
f(x) = (-5/4)x + 5
