Answer:
B) 6+6+33+44+55
Step-by-step explanation:
We assume your prism has bases that are 3-4-5 triangles, and that it is of length 11. The the surface area is the sum of the areas of the bases and the areas of each of the rectangular sides.
base area = (1/2)(3)(4) = 6
face area = (3)(11) +(4)(11) +(5)(11) = 33 +44 +55
Surface area = base area + base area + face area
Surface area = 6 + 6 + 33 + 44 + 55
Answer:
8 is the answer
Step-by-step explanation:
Answer: 20 liters
<u>Step-by-step explanation:</u>
The mixture is 60 liters. The ratio is 2 : 1 (2 parts to one part)
60 ÷ (2 + 1) = one part
60 ÷ 3 = 20
Therefore, the ratio of 2 : 1 means 2(20) liters milk to 1(20) liters water
If we change it to a ratio of 1 : 2, then we have 1(20) liters milk to 2(20) liters water.
2:1 ratio has 20 liters water
1:2 ratio has 40 liters water
The amount of water added is 40 - 20 = 20 liters
