Question

Dolly says a person's hair grows at about one-half inch per month. Julia measured her own hair strands and after three months, they grew 1 and 15/16 inches. Does this square with what Dolly said?

a) Yes, it aligns perfectly with Dolly's estimation.
b) No, the growth exceeds Dolly's estimation.
c) Yes, it falls slightly short of Dolly's estimation.
d) No, the growth is substantially less than Dolly's estimation.

Answer 1

Julia's hair growth of 1 and 15/16 inches over three months exceeds Dolly's estimate of ½ inch per month, which would be 1½ inches.

Step-by-step explanation:

Dolly says that hair grows at about one-half inch per month. Julia measured her own hair strands and found that they grew 1 and 15/16 inches after three months. To verify whether Julia's observation aligns with Dolly's statement, we need to calculate the expected hair growth over three months based on Dolly's estimate.

According to Dolly, the expected hair growth in three months would be:

½ inch/month × 3 months = 1½ inches.

Julia's hair growth of 1 and 15/16 inches is slightly greater than the expected 1½ inches. Therefore, the correct answer is:

b) No, the growth exceeds Dolly's estimation.
