A human hair has a diameter of about 4x10^-3 inches. A fingernail is about 0.011 inches thicker. How thick is a fingernail? Write your answer as decimal to 3 places.
To find the thickness of a fingernail, we add the diameter of a hair to the given thickness of a fingernail: 4x10^-3 inches + 0.011 inches = 0.014 inches. Answer: \boxed{0.014}.
To find the thickness of a fingernail, we'll subtract the diameter of a human hair from the thickness of a fingernail.
Given:
Diameter of a human hair = 4 x 10^-3 inches
Thickness of a fingernail = Diameter of a human hair + 0.011 inches
Substituting the given values:
Thickness of a fingernail = (4 x 10^-3) + 0.011 inches
Calculating the value:
Thickness of a fingernail = 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 find the difference between the diameter of a human hair and the thickness of a fingernail.
The diameter of a human hair is given as 4x10^-3 inches.
The thickness of a fingernail is given to be 0.011 inches thicker than the diameter of a hair.
To find the thickness of a fingernail, we add this difference to the hair diameter:
Thickness of fingernail = Diameter of hair + Difference
Thickness of fingernail = 4x10^-3 inches + 0.011 inches
Simplifying, we get:
Thickness of fingernail = 0.015 inches
Therefore, the thickness of a fingernail is 0.015 inches.
