Question

If David and jake each looked at a strand of their hair under a microscope measured the diameter jake strand was 0.005 cm in the diameter David strand was 0.0012 cm in diameter

Answer 1

`=(0.005)/(0.0012)`

= 4.17

`\approx 4`

Jake's strand represents 4 times David's strand.

Explanation:

* microscope measured the diameter jake strand was 0.005 cm in the diameter

* David strand was 0.0012 cm in diameter

To find the ratio , we will have to divide them

k=0.005cm and

d=0.0012cm

by dividing we get,

`=(0.005)/(0.0012)`

= 4.17

`\approx 4`

Therefore, Jake's strand represents 4 times David's strand.

Answer 2

Jake's strand represents 4 times David's strand.

Explanation:

To find the ratio between these diameters, we just need to divide them

`k=0.005cm` and
`d=0.0012cm`

If we divide

`(k)/(d)=(0.005)/(0.0012) \approx 4`

Therefore, Jake's strand represents 4 times David's strand.
