Answer:
a 20 X 40 X x
b just a guess but 2 centimeters
c 1600 or 800 depending on what x is
The correct answer is "<span>Gallons per minute, because the independent quantity is time in minutes and the dependent quantity is the volume of water in gallons."
The dependent quantity is what is the calculated dependent on your independent. So, the volume of water in gallons is depending on the amount of time.</span><span>

C) (esther?) The orbal velocity is constant.
If it weren't constant, we wouldn't be revolving around the sun at all times, would we? :)

final answer, simplified:
Sinθ=opposite side/hypotenuse
cosθ=adjacent side/hypotenuse
where both the sides are relative to theta.
in this case, 22 is your hypotenuse. theta (θ) is the angle you are examining. i've included a diagram for reference because the equations may format differently depending on which angle you choose as theta.
using my diagram:
sinθ = o/h
sin 15 = o/22
sin 15(22) = o
o=5.69m/s
therefore the vertical component is about 5.69m/s.
cosθ=a/h
cos15 = a/22
cos15(22) = a
a = 21.25m/s
therefore, your horizontal component is about 21.25m/s.
