Question

15 multiple choice 1 point if a certain piece of music is written in 3/8, how many eighth notes are required for one measure of music? 6 12 3 4 8 16 multiple choice 1 point if a golden rectangle has a width of 11 feet, what is its length? (round your answer to the nearest tenth of a foot.) 17.8 feet 6.2 feet 7.0 feet 6.4 feet 6.6 feet

Explanation:

Question 15

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 that there are 3 beats in a measure.
So, the number of eighth - notes in one measure is 3.

Step1: Recall golden ratio formula

The golden ratio $\varphi=\frac{1 + \sqrt{5}}{2}\approx1.618$. For a golden rectangle, the ratio of length $L$ to width $W$ is the golden ratio, i.e., $\frac{L}{W}=\varphi$.

Step2: Solve for length

Given $W = 11$ feet, then $L=\varphi\times W$. Substitute $\varphi\approx1.618$ and $W = 11$ into the formula: $L\approx1.618\times11=17.798\approx17.8$ feet.
