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 a fingernail, we will add the thickness of a hair (4×10^−3 inches) to the additional thickness of a fingernail (0.011 inches):
4×10^−3 + 0.011 = 0.015 inches
Therefore, the thickness of a fingernail is 0.015 inches.
To find the thickness of a fingernail, we need to add the diameter of a human hair to the additional thickness of a fingernail.
Given:
Diameter of a human hair = 4 × 10^(-3) inches
Additional thickness of a fingernail = 0.011 inches
To find the total thickness of a fingernail, we add these two values:
Total thickness = Diameter of a human hair + Additional thickness of a fingernail
Total thickness = 4 × 10^(-3) + 0.011
Total thickness = 0.004 + 0.011
Total thickness = 0.015
Therefore, the thickness of a fingernail is 0.015 inches (rounded to 3 decimal places).
To find the thickness of a fingernail, we need to calculate the difference between the diameter of a human hair and the additional thickness of a fingernail.
Given that the human hair has a diameter of 4 × 10^(-3) inches and the fingernail is about 0.011 inches thicker, we can set up the equation:
Thickness of fingernail = Diameter of hair + Additional thickness of fingernail
Thickness of fingernail = 4 × 10^(-3) + 0.011
Adding these values, we get:
Thickness of fingernail = 0.015 inches
Therefore, the thickness of a fingernail is 0.015 inches.
