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: ![\pi r^2h](https://tex.z-dn.net/?f=%5Cpi%20r%5E2h)
Blue cup:
![\pi 2^2(8)\\\pi 4(8)\\\pi 32](https://tex.z-dn.net/?f=%5Cpi%202%5E2%288%29%5C%5C%5Cpi%204%288%29%5C%5C%5Cpi%2032)
It would take 16 times to drain it completly.
Green cup:
![\pi 4^2(8)\\\pi 16(8)\\\pi 128](https://tex.z-dn.net/?f=%5Cpi%204%5E2%288%29%5C%5C%5Cpi%2016%288%29%5C%5C%5Cpi%20128)
It would take 4 times to drain it completly.

Answer:
k=5b/4−3/4
Step-by-step explanation:
3-3k+7k=5b
Isolate the variable by dividing each side by factors that don't contain the variable.
k=5b/4−3/4

Answer:
350
Step-by-step explanation:
Let the number of adult tickets be x, then the number of student tickets sold would be (x–54).
We now have
x+(x–54)=646
2x=700
x=350
Therefore, 350 adult tickets were sold.
