Question

Charla wants to cover a certain rectangular area of her driveway with a picture using chalk. If she completes 23 of the area in 12 hour, how long will it take her to complete the entire picture

Answer 1

Rosie is planning to make raspberry lemonade for a party. She needs to add 2 scoops of raspberry to every 5 cups of lemonade. The data table shows the ratios needed. At what ratio does the constant of proportionality appear?

Answer 2

If Charla completes 23% of the area in 12 hours, then she completes 1% of the area in 12/23 = <<12/23=0.5217391304347826>>0.5217 hours.
Therefore, it will take Charla 0.5217 x 100 = 52.17 hours to complete the entire picture. Answer: \boxed{52}.

Answer 3

To find the ratio at which the constant of proportionality appears, we need to compare the number of scoops of raspberry to the number of cups of lemonade.

From the data table, we can see that for every 2 scoops of raspberry, there are 5 cups of lemonade.

Therefore, the constant of proportionality appears at the ratio of 2 scoops of raspberry to 5 cups of lemonade, which can be written as 2:5.
