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 add the diameter of a human 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 can add the diameter of a human hair (4×10^(-3) inches) to the thickness of a fingernail (0.011 inches).
Adding them together, we have:
4×10^(-3) + 0.011
= 0.004 + 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 additional thickness to the diameter of a human hair.
The diameter of a human hair is given as 4×10^-3 inches.
The additional thickness of a fingernail is given as 0.011 inches.
To find the total thickness of the fingernail, we add these two values together:
4×10^-3 + 0.011 = 0.015 inches.
Therefore, the thickness of a fingernail is 0.015 inches.
