Answer 1

15 x 39/500 = 585/500 = 1.17 inches tall

Answer 2

The vertical height of the stack in inches is:

1.17 inches.

Explanation:

The thickness of one nickel is: 39/500 inch.

Now, it is given that we stack (39/500)*(15) = 585/500 = 1 85/500 = 1 17/100 = 1.17 inches fifteen nickels vertically.

This means that the total vertical length will be:

Thickness of one nickel×Number of nickels stacked.

i.e.

(39/500)*(15) =585/500=1.17 inches
