a human hair has a diameter of about 4*10^-3 inches a fingernail is about 0.011 inches thicker. How thick is a fingernail write your answer as a decimal to 3 places

Answer 1

To find the thickness of a fingernail, we need to calculate the difference between the diameter of a human hair and the fingernail thickness.

Given:
Diameter of a human hair = 4 * 10^-3 inches
Thickness of a fingernail = 0.011 inches

Fingernail thickness - Human hair diameter = 0.011 inches - 4 * 10^-3 inches

= 0.011 inches - 0.004 inches

= 0.007 inches

Therefore, the thickness of a fingernail is 0.007 inches.
