Answer:
90 -63=27 so the answer is 27 because complementary angles add to 90
Given that <span>the average volume of water that flows over the falls each second is

gallons.
There are 3,600 seconds in one hour.
Thus, in one hour,

gallons of water </span><span>flows over the falls.
</span>Therefore, the amount of water that flows over the falls is <span>

5/8÷1/3=5/8×3/1
(multiply by reciprocal instead of dividing)
5/8×3/1=15/8=1.875
Hello
This question requires us to change the subject of a formula. This can be achieved by following the order of operations in reverse. First, isolate the terms with our variable of interest, x:
ax - bx = z - y
Then, we take x out as it is being multiplied to both a and b:
x(a - b) = z - y
Dividing (a - b) on both sides, we get:
x = (z - y) / (a - b)
Thus, the answer is A
