Answer:
24t + 270 gallons
Step-by-step explanation:
Given that :
Addition rate 1 = 15 gallons per minute
Addition rate 2 = 9 gallons per minute
Total time spent adding water = half an hour = 30 minutes = 0.5 hour
Time spent adding water at faster rate = t
Time spent addition water at slower rate = (30 - t)
Total number of water added to the pool :
Amount of water added = addition rate * time
Hence,
Amount of water added at faster rate :
(15 gal / min) * t = 15t gallons
Amount added at slower rate :
(9 gal / min) * (30 - t) = (270 - 9t) gallons
Total amount of water added to the pool:
15t gallons + (270 - 9t)gallons
15t + 270 + 9t
24t + 270 gallons
Answer:
Keaton solved it right.
Step-by-step explanation:
Both students did the first step correctly, but Emily divided on the last step instead of multiplying. When there is a division on the other side of the equation, you would have to multiply the denominator on both sides. Keaton correctly multiplied the denominator of 3 on each side which gives 12 * 3 = 36.
I really hope this helps! :)
Answer:
Cups of white paint = 24 * 1/4 = 6 cups
Cups of red paint = 24 * 1/4 = 6 cups
Cups of blue paint = 24 * 1/2 = 12 cups
Step-by-step explanation:
1/4 cup of white paint is added for every :
1/4 cup of red paint and 1/2 cup of blue paint :
1 gallon = 16 cups
1 1/2 gallons = 16 + 8 = 24 cups
To make 1 cup of lighter purple paint ;
1/4 cup of white + 1/4 cup of red + 1/2 cup of blue
Therefore ;
To make 24 cups of lighter purple paint :
Cups of white paint = 24 * 1/4 = 6 cups
Cups of red paint = 24 * 1/4 = 6 cups
Cups of blue paint = 24 * 1/2 = 12 cups
