Answer:

D) 45 ft

Step-by-step explanation:

The two triangles are shown below.

Given:

BC = 60 ft, CD = 24 ft and DE = 18 ft.

Since, the two triangles are similar, their corresponding sides are in proportion.

So, \frac{AB}{DE}=\frac{BC}{CD}=\frac{AC}{CE}

Now, consider the proportion of sides,

\frac{AB}{DE}=\frac{BC}{CD}\\AB=\frac{BC}{CD}\times DE\\AB=\frac{60}{24}\times 18\\AB=\frac{60\times 18}{24}=45\ ft

Therefore, the distance between A and B is 45 ft.

The middle school choir concert was 1 1/4 hours long. Each song was 1/8 of an hour. How many songs did the audience hear during
kobusy [5.1K]

Answer:

10

Step-by-step explanation:

let s = total songs sung at the concert

If it took 1/8 to sing one song, it would take 1/8 x s hours to sing s songs

\frac{1}{8}s = 1\frac{1}{4}

1/8 s = 5/4

Divide both sides of the equation by 8

s = 5/4 x 8

s = 10
