In science class, the students were asked to create a container to hold an egg. They would drop this container from a window that is 25 feet above the ground. If the equation of the container's pathway can be modelded the equation h=-16t^2+25 , how long will it take the container to reach the ground?

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
