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 finger nail? 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 (4 x 10^-3 inches) to the additional thickness of the fingernail (0.011 inches).
4 x 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 start with the diameter of a human hair, which is given as 4 x 10^-3 inches (in scientific notation). This means that the hair has a decimal value of 0.004 inches.
To find the thickness of the fingernail, we need to add 0.011 inches to the hair's diameter.
0.004 inches + 0.011 inches = 0.015 inches
Therefore, the thickness of a fingernail is 0.015 inches when rounded to three decimal places.
To find the thickness of a fingernail, we need to add the thickness of a hair to the given thickness difference.
Given:
Thickness of a hair: 4 x 10^(-3) inches
Thickness difference: 0.011 inches
To find the thickness of a fingernail:
Thickness of a fingernail = Thickness of a hair + Thickness difference
Thickness of a fingernail = 4 x 10^(-3) + 0.011
Calculating the sum:
Thickness of a fingernail = 0.015 inches
Therefore, the thickness of a fingernail is 0.015 inches
