Answer: There are 3360 homes in a community of 12000 would be heated by electricity.

Explanation:

Since we have given that

According to the 2000 U.S. census, 7 out of every 25 homes are heated by electricity.

At this rate, we need to find the number of homes in a community of 12000 would be heated by electricity.

Let the number of homes in a community would be heated by electricity be x.

Since there is a direct variation,

So, it becomes,

`(7)/(25)=(x)/(12000)\\\\x=(7* 12000)/(25)\\\\x=3360`

Hence, there are 3360 homes in a community of 12000 would be heated by electricity.

Answer 2

7/25 homes are heated by electricity. Multiply that by 12,000. You'll get 3,360. So therefore 3,360 homes out of 12,000 are heated by electricity according to the 2000 census.
