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 as a decimal to 3 places.

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).

So, the total thickness of a fingernail is 4 * 10^-3 inches + 0.011 inches.

Adding these values, we get 0.015 inches.

Therefore, the thickness of a fingernail is 0.015 inches when written as a decimal to 3 places.

To find the thickness of a fingernail, we can add the thickness of a human hair (4 * 10^-3 inches) to the additional thickness of a fingernail (0.011 inches).

So, the total thickness of a fingernail is:
4 * 10^-3 inches + 0.011 inches = 0.015 inches

Therefore, the thickness of a fingernail is 0.015 inches.

To determine the thickness of a fingernail, we need to add the thickness of a human hair to the given difference. Let's break down the calculation step by step:

1. Start with the diameter of a human hair: 4 × 10^-3 inches.
2. Add the given difference of a fingernail: 0.011 inches.
3. Combine the two values: 4 × 10^-3 + 0.011 = 0.015 inches.

Therefore, the thickness of a fingernail is 0.015 inches.
