Answer:
14
Step-by-step explanation:
Let the number of white marbles be W and the number of red marbles be R, therefore, W + R = 25
and, W = 2R -8
Using first equation, R = 25 - W and putting it in second, we get,
W = 2(25 - W) - 8
W = 50 - 2W - 8
3W = 42
W = 14
Answer:
x = -72
Step-by-step explanation:
-72 + 8 = -64
The third square root of -64 is -4
The formula for the volume of a cylinder is V=3.14r^2(h).
So substituting the volume: 20,403.72=3.14r^2(h).
To solve for ‘r’, divide both sides by 3.14h
r^2=6,498/h
Then find square root of both sides
r= sqrt(6,498/h)
Since ‘h’ is not specified here, it cannot be solved further.
