Answer:

a) 33; b) 8; c) 145

Step-by-step explanation:

There were 29 students in band.  This includes the 9 in both band and drama; this leaves 20 in only band.  

There were 17 students in drama.  This includes the 9 in both band and drama; this leaves 8 in only drama.

There were 70 students sampled; this means that

70-(20+8+9) = 70-37 = 33 students in neither band nor drama.

There were 8 in only drama.

Since there were 29/70 in band, this means the director can assume he will have

29/70(350) = 29/70(350/1) = 10150/350 = 145 to show up the first day.

a strip of paper is 9/10 of an inch long. you need to cut the paper into 3/12 inch pieces. how many pieces will you be able to c
e-lub [12.9K]
We have to divide 9/10 by 3/12.

if we divide by a fraction, we can instead multiply by it's inverse:

\frac{9}{12}/ \frac{3}{12}  = \frac{9}{12} * \frac{12}{3}

so now we count:

\frac{9}{12} * \frac{12}{3} =\frac{9}{1} * \frac{1}{3}=3

so we can cut exactly 3 pieces!
