Answer:
C. 0.12
Step-by-step explanation:
Let's use a sample number of 100
Out of 100 members, 50 are in the brass section
Out of those 50, 24% play the trombone. This means that 12 people total play the trombone.
12/100 is .12.. That is the final answer
12 - 23 = -11
-11 + 1,345 = 1,334
1,334/123 = 10.85
Answer:
74 words per minute
Step-by-step explanation:
If the tiles
3478 words ———————-> 47 mins
? Words ————————> 1 min
cross multiply
?=74
The two triangles BQA and DQC are similar triangles. The ratio of corresponding sides of similar triangle is the same.
So, we can write:
BQ : BA = DQ : DC
15 : 32 = DQ : 19.2
⇒
32 * DQ = 19.2 * 15
DQ = 9
We are to find the length of BD.
BD = BQ + QD = 15 + 9 = 24
So the answer to this question is 24
