In the circus, a leopard has been trained to jump through a ring of fire that has a diameter of 2 meters. what is the ring's radius?

The radius is half the diameter. Divide the diameter by 2 to find the radius.

Radius = 2 meters / 2 = 1 meter.

it would take 7/10 of an hour too fill the pool.

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
