<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.
Angle of depression = 12.52°
The right angle triangle formed has a height of 200 ft and a base of 900 ft.
The opposite side of the triangle is 200 ft while the adjacent side of the triangle is 900 ft.
Using tangential ratio we can find the angle of depression. Therefore,
Let
x = angle of depression
tan x = opposite/adjacent
opposite = 200 ft
adjacent = 900 ft
tan x = 200/900
tan x = 2/9
x = tan⁻¹ 2/9
x = tan⁻¹ 0.222
x = 12.5166739144
x = 12.52°

Answer:
Step-by-step explanation:
A monomial is a type of polynomial that has only one term and when there are two terms in the polynomial then it is called binomial.
Say for example (ax) is a monomial and (ax + b) is a binomial.
In our case the cube of a monomial is 
Therefore, the monomial will be ![\sqrt[3]{\frac{a^{27} }{8}} =\frac{a^{9} }{2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7Ba%5E%7B27%7D%20%7D%7B8%7D%7D%20%3D%5Cfrac%7Ba%5E%7B9%7D%20%7D%7B2%7D)
(Answer)
Since it's a cube all the side lengths are the same. So the calculation would be 6.1x6.1x6.1 or 6.1^3
V=226.981cm^3
V=Length x width x height
Multiply 11 yards by 7 yeards and you will get ur answrr
