If 1 inch = 2.54cm, then set up and solve a proportion that finds how many inches, n, there are in 10 cm. (Round your answer to the nearest tenth)

Given:

1 inch = 2.54 cm

To find:

The number of inches, n, in 10 cm.

Solution:

We have,

1 inch = 2.54 cm

On dividing both sides by 2.54, we get

inch = 1 cm

On multiplying both sides by 10, we get

inch = 10 cm

Now, number of inches n in 10 cm is

Therefore, the number of inches in 10 cm is 3.9.

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
