Answer:
6 yards by 11 yards
Step-by-step explanation:
Factors of 66 are ...
66 = 1·66 = 2·33 = 3·22 = 6·11
The last pair of factors differ by 5, so represent the solution to the problem.
The width of the parking lot is 6 yards; the length is 11 yards.
Answer:
Part A: A ratio of 2:1 means that he uses<u><em> </em></u><u><em>2 cups of yellow paint for each cup of blue paint.</em></u>
-------------------------------------------------------------------------------------------------
Part B: The ratio of yellow to blue is 2:1 = 2/1. So, if for 2 yellow is 1 blue, then for 1 yellow is x:
2/1 = 1/x
x = (1*1) / 2
x = 1/2
<u><em>For each cup of yellow paint, Greg should add 1/2 cup of blue paint.</em></u>
<u><em></em></u>
-------------------------------------------------------------------------------------------------
Part C: 6 cups cost $54, then 1 cup cost:
54 / 6 = 9
<u><em>The price per cup of yellow paint is $9.</em></u>
