Given:
It is stated that
PQ ⊥ PS and
∠QPR = 7x-9
∠RPS = 4x+22
To find the measure of ∠QPR.
Formula
According to the problem PR sits between PQ and PS,
Consequently,
∠QPR+∠RPS = 90°
Now,
Inserting the values for ∠RPS and ∠QPR yields

or, 
or, 
or, 
or, 
Substituting the value of
into ∠QPR gives us
∠QPR = 
or, ∠QPR = 
So,
The measure of ∠QPR is 40°.
Answer: See explanation
Step-by-step explanation:
To determine how many boxes of sugar Alonso can purchase, we can express the scenario as follows:
= 2.75 + 11.50S ≤ 55
Expanding this gives us:
2.75 + 11.50S ≤ 55
11.50S ≤ 55 - 2.75
11.50S ≤ 52.25
S ≤ 52.25 / 11.50
S ≤ 4.54
Thus, he is able to buy 4 boxes of sugar.
The mean is found by summing all data values and dividing that total by the number of values.
The mean fitness score equals 3.2 points. If every student had the identical score, each student's fitness score would be 3.2 points.
Therefore, the correct choice is D. 3.2 points.
Answer:Part a) 
Part b) When Jenny divides the square root of her favorite positive integer by
, the result is an integer.
Step-by-step explanation:
Let
x-------> the favorite positive integer
Part a)
1) For 
-----> the product results in an integer
thus
The number
could potentially be Jenny's favorite positive integer
2) For 
-----> the product results in an integer
thus
The number
could potentially be Jenny's favorite positive integer
3) For 
-----> the product results in an integer
thus
The number
could potentially be Jenny's favorite positive integer
Part B)
1) For 
-----> the outcome is an integer
2) For 
-----> the outcome is an integer
3) For 
-----> the outcome is an integer
Therefore
When Jenny divides the square root of her favorite positive integer by
, she obtains an integer as a result.
