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

Blue cup:

\pi 2^2(8)\\\pi 4(8)\\\pi 32

It would take 16 times to drain it completly.

Green cup:

\pi 4^2(8)\\\pi 16(8)\\\pi 128

It would take 4 times to drain it completly.

Scorpion4ik [409]

ANSWER

3) b

EXPLANATION

Given that:

\sin(20 \degree)  = a

and

\cos(20 \degree)  = b

Recall that the sine and cosine functions are equal for complementary angles.

This implies that,

\sin(70 \degree)  =  \cos(20 \degree)

\sin(70 \degree) = b
