Make each known side into a ratio like so...
75/6
(Because 75 is the shadow casted by the building, and 6 is the shadow casted by sarah)
and 50/x
(50 is how tall the building is and sarah's height is what needs to be found)
Therefore,
75 50
---- -----
6 x
Do cross products;
50 x 6 = 75 x X
300 = 75x
Divide by 75
x = 4ft
Answer:
Jim - Ocean, because lakes don't have waves to surf on. Oceans do.
Darrell - Lake, because it's the only other water option.
Janet - Mountains, because Stephanie doesn't live in the mountains.
Stephanie - Desert, because it's the only one left.
Hope I could help!

Sixth power of 10 (10^6) equals 10 with five extra zeros (1000000), which is nothing else but million. If you multiply it by 93, you will get the answer - the Sun is approx. 93000000 miles from Earth.
