Apool holds 33500 gallons of water. the pool is filled at a constant rate of 485 gallons every 6.5 minutes. select whether each statement is true or false.

the unit rate for filling the pool is 74 gallons per minute

it will take 4 hours and 15 minutes to fill the pool to 85% of its capacity.

the difference between the pool being 64% full and 48% full is 3600 gallons.

a slow leak has left the pool with only 19800 gallons, a 12% decrease.

the pool can be completely filled in less than 5 hours.

1. It's True. Since it's 485 gallons every 6.5 minutes, then to find 1 minute you would do 485/6.5 which is approximately 74 gallons.

2. It's False. 85% of 33500 is 28475 gallons. If you divide that by 74, since that's the number of gallons per minute, you get approximately around 384 minutes. Since you want the time in hours, you divide 384 by 60, and you get the decimal 6.4. Since 6 hours is greater than 4 hours, it's false.

3. It's False. 64% of 33500 is 21440 gallons. 48% of 33500 is 16080 gallons. 21440-16080 is 5360 gallons, not 3360 gallons.

4. It's False. To find the percent of change, you first need to subtract 19800 from 33500, which gives you a result of 13700. Then you divide 13700/33500, which gives you a quotient of approximately 0.41. You multiply that by 100 to find the percent, which is 41%. 41% is not equal to 12%.

5. It's False. Since the unit rate is 74 gallons per minute, you divide 33500 by 74 to see how many minutes it takes. That gives you a quotient of approximately 453 minutes. You divide that by 60 since you want the time in hours, and the quotient of that is 7.55. 7 hours is greater than 5, so it's false.

I'm not too sure about some of them, so you might want to check my math. :)
