<h3>Answer:  1.3 seconds</h3>

Explanation:

Replace h with 0. Solve for t.

h = -16t^2 + 26\\\\0 = -16t^2 + 26\\\\16t^2 = 26\\\\t^2 = 26/16\\\\t^2 = 1.625\\\\t = \sqrt{1.625}\\\\t \approx 1.2748\\\\t \approx 1.3\\\\

It takes about 1.3 seconds for the balloon to hit the ground.

The ages of Edna, Ellie, and Elsa are consecutive integers. The sum of their ages is 108. What are their ages?
diamong [38]
All I did was guess and check. I started with the 30s because their sum would be nine and there might be a one to carry to make it 10. After many tries (well, not many, I'm just being dramatic) I got 35, 36, and 37. Hope I helped.
