Given:
It is given that,
PQ ⊥ PS and
∠QPR = 7x-9
∠RPS = 4x+22
To find the value of ∠QPR.
Formula
As per the given problem PR lies between PQ and PS,
So,
∠QPR+∠RPS = 90°
Now,
Putting the values of ∠RPS and ∠QPR we get,
![7x-9+4x+22 = 90](https://tex.z-dn.net/?f=7x-9%2B4x%2B22%20%3D%2090)
or, ![11x = 90-22+9](https://tex.z-dn.net/?f=11x%20%3D%2090-22%2B9)
or, ![11x = 77](https://tex.z-dn.net/?f=11x%20%3D%2077)
or, ![x = \frac{77}{11}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B77%7D%7B11%7D)
or, ![x = 7](https://tex.z-dn.net/?f=x%20%3D%207)
Substituting the value of
in ∠QPR we get,
∠QPR = ![7(7)-9](https://tex.z-dn.net/?f=7%287%29-9)
or, ∠QPR = ![40^\circ](https://tex.z-dn.net/?f=40%5E%5Ccirc)
Hence,
The value of ∠QPR is 40°.
The value of the quotient will result in a positive integer compared to the original two integers that started off as a negative integer
I like A as the best one
420 = 100*price - (fixed costs)
220 = 60*price - (fixed costs)
If we subtract one from the other one, we get 200 = 40*price, price = 5
that said, fixed costs are 500 - 420 = 80
Now if we move -220 to the right in Answer A, we'll get:
y = 5x -300 + 220 = 5x - 80
So it looks like A describes the model best
Answer:
I. Length, L = 9.552 meters
II. Width, W = 7.96 meters
Step-by-step explanation:
Let the length = L
Let the width = W
Given the following data;
Perimeter = 35 m
Translating the word problem into an algebraic equation, we have;
Length = 1.2W
To find the dimension of the room;
The perimeter of a rectangle is given by the formula;
P = 2(L + W)
Substituting into the formula, we have;
35 = 2(1.2W + W)
35 = 2(2.2W)
35 = 4.4W
Width, W = 7.96 meters
Next, we would find the length of the rectangle;
L = 1.2*W
L = 1.2 * 7.96
Length, L = 9.552 meters
