The length of the support post is 40 ft.
<u>Solution:</u>
Given, the height of the wall is 20 ft; support post forms 30 degree
Refer the attached image
Let us name the triangle as ABC where AB is the wall (opposite side) of 20 ft and
is 30 degree (
) and AC is the length of the post.
To find: The length of the post (AC)
we know the formula,
(trigonometric formula)
On substituting the values we get,

The value of sin 30 degree is 0.5

Due to the nature of spheres, they are all similar to each other.
Answer:
A) f(x) = 6x + 14
Step-by-step explanation:
6(1) + 14 = 20
6 + 14 = 20
6(1.5) + 14 = 23
9 + 14 = 23
6(2) + 14 = 26
12 + 14 = 26
and so on...
<h3>Philipe has to make a weekly sales of $ 3000 so that he can earn $ 360</h3>
<em><u>Solution:</u></em>
Given that,
Philipe works for a computer store that pays a 12% commission and no salary
We have to find his weekly sales have to be for him to earn $360
From given, we can say,
12 % of weekly sales will earn him $ 360
12 % of weekly sales = 360
Let "x" be the weekly sales
12 % of "x" = 360
Solve the above expression

Thus Philipe has to make a weekly sales of $ 3000 so that he can earn $ 360
