Answer:
2nd tank
Step-by-step explanation:
The rate of filling, in gallons per minute, is found by dividing gallons by minutes.
<u>Tank 1</u>
(3/4 gal)/(2/3 min) = (3/4)(3/2) gal/min = 9/8 gal/min
<u>Tank 2</u>
(5/8 gal)/(1/2 min) = (5/8)(2/1) gal/min = 10/8 gal/min
10/8 gal/min is more than 9/8 gal/minute.
The second tank is filling faster.
Answer:
The width of each bedroom is 12 feet.
Step-by-step explanation:
Each bedroom has 2 walls 13 feet long. That is a total of 8 times 13, which equals 104.
Subtract 104 from 200. That leaves 96 feet to be divided into the 8 widths.
96 ÷ 8 = 12.
12 feet is the width of each bedroom.
