Answer:
20Step-by-step explanation:
According to Triangle P R Q, if angles R P Q and P Q R are congruent, this means that two of the sides of the triangle a re also congruent (Isosceles triangle).
We can say then that length of side PR is equal to that of RQ i.e PR = RQ
Given
PR = 5n
RQ = 32+n
Required
Length of PR
Since the two sides are equal i.e PR = RQ
5n = 32+n
5n - n = 32
4n = 32
n = 32/8
n = 4
Get PR;
Since PR = 5n
PR = 5(4)
PR = 20
Hence the length of PR is 20.

Step-by-step explanation:
Calculation for How much will Gretta pay in total for this transaction
First step is to calculate the new price
New price=$65- ($65*40%)
New price=$65-26
New price=$39
Second step is to calculate the sales tax amount
Sales tax=8%*39
Sales tax=$3.12

Susan just got a promotion that increased her annual salary from $52,000 to $68,000. Susan's monthly expenses included a mortgage payment of $1 500 three minimum credit card payments that total $350, a lease payment of $280, a student loan payment of $250, and a personal loan payment of $325. How did Susan's debt-to-income ratio change with her promotion?
a. Susan's debt-to-income ratio decreased by about 2%
b. Susan's debt-to-income ratio increased by about 2%
c. Susan's debt-to-income ratio decreased by about 15%.
d. Susan's debt-to-income ratio increased by about 15%
Answer:
c. Susan's debt-to-income ratio decreased by about 15%
Step-by-step explanation:
Susan's previous salary = $52,000
Susan's new salary = $68,000
Susan's mortgage = $1,500
The total of three minimum credit card payment = $350
Her lease payment = $280
Her student loan payment = $250
Her personal loan payment = $325
Therefore, her total debt = $1,500 + $350 + $280 + $250 + $325 = $2,705
Her new Debt to loan ratio = (Her total deb)/(Her total new income) = 2705/68000 = 3.9779 %
Her previous to loan ratio = (Her total deb)/(Her total previous income) = 2705/52000 = 5.2%
The percentage change in her debt to income ratio = (5.202 - 3.9779)/5.202 ≈ 23% decrease
Therefore, the best option is Susan's debt-to-income ratio decreased by about 15%.
Answer:
c. Susan's debt-to-income ratio decreased by about 15%

What is the value of x and what does ACB equal to? Please answer as soon as possible! Thanks for your support!
Answer:
11 ; 12°
Step-by-step explanation:
3x + 28 + 2x - 10 + 5x + 52 = 180
10x = 180 - 70
x = 11
m∠C = 2(11) - 10 = 12°
Answer:
Angle ACB = 12°
Step-by-step explanation:
All angles in a triangle always add up to 180°, which gives us an equation to solve for x:
3x + 28 + 5x + 52 + 2x -10 = 180
Combine like terms
10x + 70 = 180
Subtract 70 from both sides
10x = 110
Divide both sides by 10
x = 11
Now we know the value of x, we need to just plug it in to angle ACB's given value:
2(11) - 10 = Angle ACB
22 - 10 = Angle ACB
12 = Angle ACB

Nichole needs to spend at least four hours each week practicing the guitar
she already practiced 2 1/3 hours this week she wants to split the remaining practice time evenly between the last 2 days of the week write an inequality to determine the minimum number of hours she needs to practice on each of the 2 days
Answer:
two and one third + 2x ≥ 4
Step-by-step explanation:
From the information given:
The number of hours Nicole already practiced with = [tex]2 \dfrac{1}{3}[/tex]
However, she wants to further her practice for 2 days and make sure that each day equal each other
Let consider y be the hours she practiced each day
Then, the number of hours she will practice in two days will be 2y
Thus, the total number of hours she practiced can be computed as
= [tex]2 \dfrac{1}{3}+2[/tex]
Suppose Nicole desire to practiced for at least 4 hours,
Then,
[tex]2 \dfrac{1}{3}+2 \ge 4[/tex]
Therefore, the required inequality to determine the minimum number of hours she needs to practice on each of the 2 days suppose she practiced for at least 4 hours a day is:
two and one third + 2x ≥ 4 i.e. [tex]2 \dfrac{1}{3}+2 \ge 4[/tex]

A scuba diver is swimming -2.5 feet per minute. How many minutes did it take the scuba diver to reach the depth of 11 1/4 feet
Let me = the minutes we are searching for.
(-2.5)/11_1/4 = 1/m
Rewrite 11_1/4 as 45/4.
(-2 5)/(45/4) = 1/m
Cross-multiply to find m.
45/4 = -2.5m
Divide both sides by -2.5.
45/4 ÷ -2.5 = m

The system reveals that there are 15 questions worth 2 points and 10 questions worth 3 points on the test.
Given:
Total question = 25
Marks for question= 2 or 3 points
Total marks = 60
Let x be the 2-point questions and y be the number of 3-point questions.
As, there are a total of 25 questions then
Equation1 : x+ y= 25
and, total points in the test is 60 then
Equation 2 : 2x+ 3y = 60
From equation 1: y= 25 -x.
Substitute y = 25 -x into the Equation 2
2x + 3(25-x) = 60
2x + 75- 3x= 60
75 - x = 60
-x = 60 - 75
-x = -15
x= 15
Now, the value of y is
y = 25 -x
y = 25 - 15
y = 10

if the length of a cube is 6 inches, what is the surface area?
Answer:
[tex]\huge\boxed{216 \ \text{in}^2}[/tex]
Step-by-step explanation:
We can find the surface area of an object by finding the area of all its sides and adding them up.
We know that a cube has 6 identical sides. Therefore, we can just find one side and multiply by 6.
A cube is made up of 6 squares. We can find the area of this square by squaring the length (multiplying it by itself).
Since the length is 6, that means the area of one side of the cube must be [tex]6^2 = 6 \cdot 6 = 36 \ \text{in}^2[/tex]
Since there are 6 identical sides, the total surface area must be:
[tex]36 \cdot 6 = 216 \ \text{in}^2[/tex]
Hope this helped!
A square has a side length of x + 3. A regular octagon has a side length of 3x. If the polygons have the same perimeter, determine the value of x.
Answer:
x = ⅗ = 0.6
Step-by-step explanation:
A square has four equal sides.
If a square has a side length of [tex] x + 3 [/tex], therefore,
Perimeter of the square = [tex] 4(x + 3) [/tex]
[tex] = 4x + 12 [/tex].
Also, a regular octagon has 8 equal sides.
If it has a side length of 3x, therefore:
Perimeter of the octagon = [tex] 8(3x) [/tex]
= [tex] 24x [/tex]
Given that the Perimeter of the rectangle and the octagon are the same, to find the value of x, set each perimeter equal to the other.
Thus:
[tex] 24x = 4x + 12 [/tex]
Subtract 4x from each side
[tex] 24x - 4x = 12 [/tex]
[tex] 20x = 12 [/tex]
Divide both sides by 20
x = 12/20 = ⅗ = 0.6.
