Can someone please answer this quick! It is recommended that one smoke detector be installed for every 500 square feet of floor area in a building. Write an equation to determine s, the number of smoke detectors needed for a building with 7,250 Square feet of floor space.

How many smoke detectors are needed for that building?

Equation- 7,250 divided by 500

Answer- 15

Step-by-step explanation:

thanks google for letting me look this up! ;)

s = 7,250/500

Step-by-step explanation:

If you want a smoke detector every 500 feet you divide the total amount (7,250) into (s) many 500 foot spaces. This means that you could also divide 7,250 by 500 ft to get s or the number of smoke detectors needed.

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
