12/18 = 8/x <=> 2/3 = 8/x <=> x = (3*8)/2 = 12;
Plug h = 3 and g = 27 into the expression:
Answer:
Step-by-step explanation:
Given that,
the rectangular prism has ;
- length=8meters
- width=6meters
- height=3meters
<u>As</u><u> </u><u>we</u><u> </u><u>know</u><u>,</u><u> </u>
- volume =length×width×height
- V=8×6×3
308 gallons of 7% and 77 gallons of 2% are needed to obtain the desired 385 gallons.
<h3><u>Combination</u></h3>
Since a dairy needs 385 gallons of milk containing 6% butterfat, to determine how many gallons each of milk containing 7% butterfat and milk containing 2% butterfat must be used to obtain the desired 385 gallons, the following calculation must be performed:
- 385 x 0.06 = 23.1
- 300 x 0.07 + 85 x 0.02 = 22.7
- 310 x 0.07 + 75 x 0.02 = 23.2
- 308 x 0.07 + 77 x 0.02 = 23.1
Therefore, 308 gallons of 7% and 77 gallons of 2% are needed to obtain the desired 385 gallons.
