Question

a strand of hair grows at a constant rate of $\frac{1}{2}$ inch per month. a different strand of hair grows at a constant rate of 4 inches per year. the proportional relationships select choice equivalent because select choice

Explanation:

Step1: Convert the second - hair's growth rate to monthly rate

Since there are 12 months in a year, if a strand of hair grows 4 inches per year, then the monthly growth rate is $\frac{4}{12}=\frac{1}{3}$ inches per month.

Step2: Compare the growth rates

The first strand of hair grows at a rate of $\frac{1}{2}$ inch per month and the second strand grows at a rate of $\frac{1}{3}$ inch per month. Since $\frac{1}{2}
eq\frac{1}{3}$.

Answer:

are not; the growth rates per month are different ($\frac{1}{2}
eq\frac{1}{3}$)
