The energy saved by recycling one glass bottle is enough to power a washing machine for 10 minuets. How many recycled glass bott

Mrac [35]

There are 60 minutes in one hour.
Divide 60 minutes by 10 minutes.

You get 6. That means you would need 6 recycled bottles to power a washing machine for one hour (that will be awesome if that were the case).

Have an awesome day! :)

Find the measure of a central angle of a regular polygon with 10 sides

Paraphin [41]

Answer:

114 degrees

Step-by-step explanation:

The formula to find the measure of all angles in a regular polygon is $(n-2)180$ , where n = total number of sides.

Thus, we substitute n for 10, and you get:

$(10-2)180=1440$

If the shape is a regular polygon and it has ten sides, meaning all sides are equal, then all you do is divide 1440 by 10, to get the final answer of 114.

A central angle in a regular ten-sided polygon would be 144 degrees.
