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.(1 point)
To find the thickness of the fingernail, you need to add the diameter of the hair (4×10^(-3)) and the additional thickness (0.011):
4×10^(-3) + 0.011 = 0.015
The thickness of the fingernail is 0.015 inches.
