Y = 6x
4x + y = 7
(substitute y = 6x in the ‘y’ spot in 4x + y = 7)
4x + 6x = 7
10x = 7
/10 on both sides
x = 7/10
(substitute x = 7/10 in the ‘x’ spot in either of the two equations)
y = 6x
y = 6(7/10)
y = 4.2 = 21/5
Answer:
x = 7/10
y = 21/5
ANSWER: V=167.5
EXPLANATION: Input the radius and height given in the problem and plug into the cone volume formula attached below!
45/100 is 4,500%
2/5 is 40%
18/40 is 45%
15/25 is 60%
You must do 1/2 times base times height
it should be rounded to 30.1
