A human hair has a diameter of about 4 * 10 ^ - 3 inchesA fingernail is about 0.011 inches thickerHow fingernail? Write your answer as a decimal to 3 places. (1 point)
To find the thickness of the fingernail, we can subtract the diameter of the hair from the thickness of the fingernail:
0.011 inches - 4 * 10^-3 inches = 0.011 - 0.004 = 0.007 inches.
The thickness of the fingernail is 0.007 inches.
To find out the thickness of a fingernail, we need to add the diameter of a hair to the additional thickness of a fingernail.
Given:
Diameter of a hair = 4 * 10^-3 inches
Additional thickness of a fingernail = 0.011 inches
To find the thickness of a fingernail, we add these two values:
Thickness of a fingernail = Diameter of a hair + Additional thickness of a fingernail
= 4 * 10^-3 + 0.011
= 0.015
Therefore, the thickness of a fingernail is 0.015 inches.
To determine the thickness of a fingernail, we need to add the given thickness of a human hair to the thickness of a fingernail.
Given:
Diameter of a human hair = 4 * 10^-3 inches
Thickness of a fingernail = 0.011 inches
To find the thickness of a fingernail, we can subtract half of the diameter from the thickness. Since the diameter is given, we divide it by 2.
Diameter of a human hair / 2 = 4 * 10^-3 inches / 2 = 2 * 10^-3 inches
Now, we can add the value we obtained above to the thickness of a fingernail:
Thickness of a fingernail + (Diameter of a human hair / 2) = 0.011 inches + 2 * 10^-3 inches
Now, we can calculate the answer:
0.011 inches + 2 * 10^-3 inches = 0.013 inches
Therefore, the thickness of a fingernail is 0.013 inches.
