Hmm
we see the one point is at (0,0), how nice of them
we can see esily that the width is 2 and height is 8
when rorated around the y axis, the radius is th ewidth
so the volume is that of a cylinder
V=hpir^2
h=8
r=2
pi=3.141592
V=8*3.141592*2^2
V=8*3.141592*4
V=32*3.141592
V=100.530944
round to tenth
V=100.5 cubic units
height=8 units
width=2 units
radius=2 units
cylinder
volume was 100.5 cubic units
Answer:
24 Cats.
Step-by-step explanation:
You can set up an inequality of 21/18 and 28/x.
Multiply 18 and 28, you get 504. Divide 504 by 21 and you get your answer of 24.
Answer:
(E) 450
Step-by-step explanation:
Let x represent the number of gallons of solution X that must be added to the mix. Then the amount of sugar in the mix is ...
0.20x +0.40·150 = 0.25(150 +x)
0.20x +60 = 37.5 +0.25x . . . eliminate parentheses
22.5 + 0.20x = 0.25x . . . . . . subtract 37.5
22.5 = 0.05x . . . . . . . . . . . . . subtract 0.20x
450 = x . . . . . . . . . . . . . . . . . . multiply by 20
450 gallons of solution X must be added to make a 25% sugar solution.
