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
To find the thickness of a fingernail, we need to add the diameter of a hair to the additional thickness of a fingernail.
Diameter of a hair = 4×10^(-3) inches
Additional thickness of a fingernail = 0.011 inches
Total thickness of a fingernail = 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 thickness of a human hair (4×10^(-3) inches) to the additional thickness of a fingernail (0.011 inches).
Adding these two values together:
4×10^(-3) + 0.011 = 0.015
The thickness of a fingernail is 0.015 inches.
To find the thickness of a fingernail, we need to add the thickness of a hair to the additional thickness of a fingernail.
First, let's find the thickness of a hair: 4 × 10^(-3) inches.
Next, let's add the additional thickness of a fingernail: 0.011 inches.
To find the total thickness of a fingernail, we add these two values together:
4 × 10^(-3) inches + 0.011 inches = 0.015 inches.
Therefore, the thickness of a fingernail is 0.015 inches to 3 decimal places.
