Hey there! I'm happy to help!
439.6 is 56% of the first Ferris wheel. The word is means equals, so we can set up the following equation. We will call the original wheel w.
439.6=0.56w
We divide both sides by 0.56
w=785
We divide by 3.14 to find the diameter.
785/3.14=250
Radius is half of the diameter.
250/2=125
The radius of the first Ferris wheel is 125 ft.
Have a wonderful day! :D
K - 2k = 15 + 1 + 6k - 2
-k = (15 + 1 - 2) + 6k
-k = 14 + 6k |subtract 6k from both sides
-7k = 14 |divide both sides by (-7)
k = -2

Step-by-step explanation:
H^2 = x^2 + y^2
where h is the hypotenuse, x and y are the legs.
h = 19cm
x = 12cm.
y = ?
h^2 = x^2 + y^2
y^2 = h^2 - x^2
y^2 = 19^2 - 12^2
y^2 = 361 - 144
y^2 = 217
y = sqrt(217)
y = 14.7
Letter B
