Question

One strand of human hair is about 0.001 inch in diameter. The diameter of a certain wire for jewelry is 10⁻² inch. How many times greater is the diameter of the wire than a strand of hair?

Answer 1

The diameter of the wire is 10 times greater than the diameter of a strand of hair.

Step-by-step explanation:

The diameter of a certain wire for jewelry is 10-2 inch, which can be written as 0.01 inch. On the other hand, a strand of human hair has a diameter of 0.001 inch. To find out how many times greater the diameter of the wire is than a strand of hair, we can divide the diameter of the wire by the diameter of the hair.

So, 0.01 inch / 0.001 inch = 10

Therefore, the diameter of the wire is 10 times greater than the diameter of a strand of hair.
