Step-by-step explanation:
If x = the amount of 12% and y = the amount of 20%, then x + y = 80
Since we need 80 grams of 15%, 80(.15) = 12.
We are given that .12x + .20y = 12.
We can solve the first equation for x or y. Let's do x.
x = 80 - y
.12(80 - y) + .20y = 12
9.6 - .12y + .20y = 12
.08y = 2.4
y = 30
x = 80 - 30 = 50

5/12, change the denominator to 12 cuz it has to be common
Answer:
1800 cubic in.
Step-by-step explanation:
Because the height is 1D, when it is multiplied by 10, the volume is multiplied by 10, so the answer is 180 cubic in. * 10 or 1800 cubic in.
