Answer:
v = 25.98
Step-by-step explanation:
You could do this a number of ways. Some are much longer than others. The shortest way is to use the tangent.
Formula
Tan(theta) = opposite / adjacent
Givens
Theta = 30o
Opposite = 15 km
Adjacent = x
Solution
tan(30) = 15 / v Multiply both sides by v
v*tan(30) = 15 Divide by tan(30)
v = 15/tan(30)
tan(30) = 0.5774
v = 15 / 0.5774
v = 25.98

Answer:
4,188,790,200 cubic miles to the nearest hundred.
Step-by-step explanation:
That will be the volume of an imagined sphere with radius 1000 miles.
= 4/3 * pi * (1000)^3
= 4,188,790,200 cubic miles.

Answer:
r = (5/8)q
Step-by-step explanation:
This means you want to express r in terms of q. Another way to say it is "solve for r."
Separate the variables by adding 4r+7q
16r = 10q
Divide by the coefficient of r
r = 10/16q
r = (5/8)q . . . . simplify
