Answer:
66 oz
Step-by-step explanation:
Every 2 cups have 11 ounces of ground coffee. Two times six is 12, so 11 times 6 is 66.
Another explanation is-
2/12 = 11/x
12 times 11 is 132. Then divide that by two to get 66
The answer would be
x = 160/147
or
x = 1 and 13/147
Answer:
1. area of new pen = 11

2. i. 5 feet by 2
feet
ii. 2 ½ feet by 4 ½ feet
Step-by-step explanation:
The size of the pen as planned = 5 ft long by 4 ½ ft wide
Area of the pen = length x width
= 5 x 4 ½
= 5 x 
Area of the pen = 
= 22 ½ 
But, Krista has to make the pen ½ the size of planned. So that;
area of new pen = ½ x 22 ½
= ½ x 
= 
= 11 
area of new pen = 11

The area of the new pen would be 11
.
The possible values she could use are:
i. 5 feet by 2
feet
ii. 2 ½ feet by 4 ½ feet
