<h3>
Answer: 15 hours (choice D)</h3>
================================================
Work Shown:
(6 hours)/(8 trees) = (x hours)/(20 trees)
6/8 = x/20
6*20 = 8*x ... cross multiply
120 = 8x
8x = 120
x = 120/8
x = 15
It takes him 15 hours to plant 20 trees.

Answer:
The width of the river is about 8.39 m.
Step-by-step explanation:
Tan = Opposite/Adjacent
The width of the river is the side of a right triangle opposite the angle of 40°. The 10 m distance is the length of the side adjacent to the measured angle. So, we have ...
tan(40°) = width/(10 m)
Multiplying by 10 m, we get ...
width = (10 m)tan(40°) ≈ 8.39 m
The width of the river is about 8.39 m.
