Answer:
15 gallons
Step-by-step explanation:
If x is the gallons of 30% butterfat cream, and y is the gallons of 3% butterfat milk, then:
x + y = 45
0.30 x + 0.03 y = 0.12 (45)
Solve the system of equations with substitution or elimination. Using substitution:
0.30 x + 0.03 (45 − x) = 0.12 (45)
0.30 x + 1.35 − 0.03 x = 5.4
0.27 x = 4.05
x = 15
You need 15 gallons of 30% butterfat cream.
Answer:
Let the height of the larger box = h
and length and width of the larger box = l and w , repectively
Now , Let find the volume of the larger box
Volume = length * width * height
So Volume of the larger box = l*w*h = lwh
Now the question says
the height of the smaller box is 80% of the height of the larger box
It means
Height of the smaller box = 80% of h = 0.80*h = 0.80h
and the other two dimensions are same so it means length and width of the smaller box = l and w
so, Volume of the smaller box = l*w*0.80h = 0.80lwh
So the Difference in the volume of the two boxes = Volume of larger box - Volume of smaller box
therefore , Difference in the Volume of two boxes = lwh - 0.80 lwh = 0.20lwh
