Set up a proportion of 5 over 3 and then x over 17
Cross multiply to get 17x=85
Then divide by 17
To get x to equal 28.33.
x=total height.
Answer:
20
Step-by-step explanation:
c = 5(68-32)/9
c = 5(36)/9
c = 20
Step-by-step explanation:
98 = 188t - 16t^2
-16t^2 + 188t = 98
-16t^2 + 188t - 98 = 0
8t^2 - 94t + 49 = 0
Use the quadratic formula with a = 8 , b = -94 , c = 49 to get the solutions
t = [(47 - root 1817) / 8]≈ 0.55
and
t = [(47 + root 1817) / 8] ≈ 11.20
