V = <span>πr^2h
We are given the diameter of 2, which means the radius is 1.
V = </span><span>π*1^2 * 3
</span>V = <span>π * 3
So the answer is V = 3</span>π or V ≈ 9.42
-w+4(w+3)=-12
-w+4w+12=-12
3w=-12-12
3w=-24
w=-8
HOPE I HELPED!!!
Answer:
Step-by-step explanation:
We have 2 linear equations, and in both, the amount of merchandise you would have to purchase is "x", the unknown. We are asked to find that value of x.
The first equation is
C(x) = .30x + 90, which says that the cost of this plan is a fixed $90, and you pay 30% of the manufacturer's cost, x.
The second equation is
C(x) = .80x + 40, which says that the cost of this plan is a fixed $40, and you pay 80% of the manufacturer's cost, x.
If we want to know when the cost of these 2 are equal to each other, we set the equations equal to each other and solve for x:
.3x + 90 = .8x + 40 so
-.5x = -50 so
x = $100
The cost for each plan will be the same at this value of x, but we will plug in 100 for x in each just to make sure we did it right:
C(100) = .3(100) + 90
C(100) = 30 + 90
C(100) = 120 and
C(100) = .8(100) + 40
C(100) = 80 + 40
C(100) = 120
Your answer will be D. hope I helped and its the only one that is reasonable
Answer:
One
Step-by-step explanation:
The graphs of these two equations intersect at one point. This means there will only be one solution to the system.
