Find the volume of the composite figure. Use the button and round to the nearest whole number. What is the volume of the cone? Copy and paste a formula to help show your work: V = r2h, V =13r2h, or V =43r3 Volume: 10 cm What is the volume of the hemisphere? Copy and paste a formula to help show your work: V = r2h, V =13r2h, or V =43r

Hemisphere: d x 4 cm

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

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
