Answer

Question 15

Explanation:

Step1: Understand time - signature meaning

In a time - signature like 3/8, the bottom number 8 indicates that an eighth - note gets one beat, and the top number 3 indicates the number of beats in a measure.

Step2: Determine number of eighth - notes

Since each eighth - note is one beat and there are 3 beats in a measure (from the top number of the time - signature 3/8), the number of eighth - notes in one measure is 3.

Answer:

C. 3

Question 16

Explanation:

Step1: Recall the ratio of a golden rectangle

The ratio of the length (L) to the width (W) of a golden rectangle is the golden ratio (\varphi=\frac{1 + \sqrt{5}}{2}\approx1.618). So, (L=\varphi\times W).

Step2: Substitute the given width

Given (W = 11) feet. Then (L=1.618\times11). [L=1.618\times11 = 17.798\approx17.8] feet.

Answer:

A. 17.8 feet
