Answer:A rectangular storage container with an open top is to have a volume of 18 cubic meters. The length of it's base is twice the width.: let x = the width of the base then 2x = the length of the base and h = height of the box: 2x^2 = the area of the base 2(2xh) = 4xh = area of the two vertical sides 2xh = area of the two other vertical sides then
Step-by-step explanation:
Answer:
y=1/2x-2
Step-by-step explanation:
1. Find slop by subtracting y values over subtracting x values, which will get you the m value
-1+3 / 2+2 = 1/2

Let
be the amount (gal) of the 40% slime solution you end up using. You want to end up with 120 gal of the 50% solution, so that you would use
gal of the 70% solution.
You want the final solution to consist of 50% slime, or 60 gal of slime. Each gal of the 40% solution contributes 0.4 gal of slime, while each gal of the 70% solution contributes 0.7 gal of slime. This means
![0.4x+0.7(120-x)=0.5\cdot120=60](https://tex.z-dn.net/?f=0.4x%2B0.7%28120-x%29%3D0.5%5Ccdot120%3D60)
![\implies0.4x+84-0.7x=60](https://tex.z-dn.net/?f=%5Cimplies0.4x%2B84-0.7x%3D60)
![\implies24=0.3x](https://tex.z-dn.net/?f=%5Cimplies24%3D0.3x)
![\implies x=80](https://tex.z-dn.net/?f=%5Cimplies%20x%3D80)
so the answer is B.
Dylan is wrong because if you multiply that ratio times 2 it would be 6/2 not 7/2.
