The volume of wood in a tree (V) varies directly as the height (h) and the square of
the girth (g). If the volume of a tree is 144 cubic meters (m3) when the height is 20meters and the girth is 1.5 meters, what is the height of a tree with a volume of 1000 and girth
of 2 meters?

y - y1 = m(x- x1)

y - (-5) = 2/3(x -0)

y + 5 = 2/3x

y = 2/3x - 5

each side has a different length.  

step-by-step explanation:

17

step-by-step explanation:

51/3=17

thus 17 is your answer.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
