Q:

If hair grows at a rate of approximately 0.44 mm per day, how manydays has a hair been growing if it measures 40 mm from follicle to tip?​

Accepted Solution

A:
Answer:It would take 90.9 daysStep-by-step explanation:The sample of the hair considered grows at 0.44mm per day, thus;      0.44mm = 1 day       40 mm = x daysSo that, by appropriate deductions,       0.44 × x = 40 × 1      0.44x = 40Divide both side by 0.44 to determine the value of x;               x = [tex]\frac{40}{0.44}[/tex]               x = 90.9090909091Therfer, it would take up to 90.9 days for the hair to measure 40mm from its follicle to tip.
