Answer:
Ounces of green paint needed = 13.8
Step-by-step explanation:
Blue paint : green paint = 25 : 115
how many ounces of green paint should she mix with 3 ounces of blue paint?
Let
Ounces of green paint needed = x
Blue paint : green paint = 3 : x
Equate both ratios
25 : 115 = 3 : x
25/115 = 3/x
25 * x = 115 * 3
25x = 345
x = 345/25
x = 13.8 ounces
Ounces of green paint needed = 13.8
Answer:
(2,3)
Step-by-step explanation:
The solution to a linear set of equations is the (x,y) point that satisfies both equations.
When you graph the equations, like in this picture, that means the intersection of the two lines.
The formula for volume of a cylinder is 3.14r^2h.
r = 3
h = 6
3.14 x 3^2 x 6
3.14 x 9 x 6
=169.56
