A human hair has a diameter of about 4 x 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 thickness of the hair to the difference between the hair's diameter and the fingernail's thickness.
Hair diameter = 4 x 10^-3 inches
Fingernail thickness = hair diameter + 0.011 inches
Fingernail thickness = 4 x 10^-3 inches + 0.011 inches
Fingernail thickness = 0.015 inches
Therefore, a fingernail is 0.015 inches thick.
To find the thickness of a fingernail, we need to add the diameter of a hair to the additional thickness of a fingernail.
The diameter of a hair is given as 4 x 10^-3 inches.
The additional thickness of a fingernail is given as 0.011 inches.
Adding these two values, the total thickness of a fingernail is:
4 x 10^-3 + 0.011
Calculating this sum, the thickness of a fingernail is approximately 0.015 inches.
To find the thickness of a fingernail, we need to subtract the diameter of a human hair from the thickness of a fingernail. The diameter of a human hair is given as 4 x 10^-3 inches. The thickness of a fingernail is stated to be 0.011 inches thicker than a hair.
To calculate the thickness of a fingernail, we can use the following formula:
Fingernail thickness = Diameter of a hair + Thickness difference
First, let's plug in the given values into the formula:
Fingernail thickness = 4 x 10^-3 inches + 0.011 inches
Now, we need to add these two values together:
Fingernail thickness = 0.015 inches
Therefore, the thickness of a fingernail is 0.015 inches.
