If Charla completes 2/3 of the area in 1/2 hour, it means she has 1 - 2/3 = 1/3 of the area left to complete.
Since she completes 2/3 of the area in 1/2 hour, she completes 1/3 of the area in 1/2 * (1/3) = 1/6 hour.
Thus, it will take her 1/6 + 1/2 = 1/6 + 3/6 = 4/6 = 2/3 hour to complete the entire picture. Answer: \boxed{\frac{2}{3}}.

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? (1 point) Responses (1, 2.5) left parenthesis 1 comma 2.5 right parenthesis (5, 2) left parenthesis 5 comma 2 right parenthesis (2, 5) left parenthesis 2 comma 5 right parenthesis (2.5, 1)
The correct answer is: (5, 2) (left parenthesis 5, comma 2 right parenthesis)
In the given scenario, the constant of proportionality appears when the ratio of 2 scoops of raspberry to 5 cups of lemonade is maintained. This means that for every 5 cups of lemonade, Rosie will always add 2 scoops of raspberry. This consistent ratio of 2 scoops of raspberry to 5 cups of lemonade defines the constant of proportionality in this scenario.
