Answer:
The green would take 4 and the blue would take 16 times respectivly. I did it by finding the volumes of the cups in terms of pi, then dividing it by the volume of the sink.
Step-by-step explanation:
So the volume of the whole half sphere is 512pi.
Now we have to find the volumes of the cup.
Equation: 
Blue cup:

It would take 16 times to drain it completly.
Green cup:

It would take 4 times to drain it completly.
Answer:
x = 18 + 9y/2
x-18 = 9y/2
(x-18)x2=9y
2(x-18)=9y
2(x-18) / 9 = y
y= 2(x-18)/9
Step-by-step explanation:
<em>Simplify 9/2y to 9y/2</em>
<em>Then Subtract 18 from both sides</em>
<em>Now Multiply both sides by 2</em>
<em>Then Regroup the terms</em>
<em>now divide both sides by 9</em>
<em>Then you will Switch sides</em>
