Answer:
m∠JNP=43°
m∠KNJ=94°
m∠KNL=43°
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
m∠JNP+m∠KNJ+m∠KNL=180° ----> by definition of supplementary angles
we have
m∠JNP=(2x+3)°
m∠KNJ=(3x+34)°
m∠KNL=(3x-17)°
substitute the values
(2x+3)°+(3x+34)°+(3x-17)°=180°
Combine like terms in the left side
(8x+20)=180
Subtract 20 both sides
8x=180-20
8x=160
x=20
Find the measure of m∠JNP
m∠JNP=(2x+3)°
substitute the value of x
m∠JNP=(2(20)+3)=43°
Find the measure of m∠KNJ
m∠KNJ=(3x+34)°
substitute the value of x
m∠KNJ=(3(20)+34)=94°
Find the measure of m∠KNL
m∠KNL=(3x-17)°

How can I Factor 9x2-1
Answer:
17 = 17^1
Step-by-step explanation:
Factor the following integer:
17
17 is not divisible by 2 since 17 is odd and 2 is even:
17 = 17 (17 is not divisible by 2)
The sum of the digits of 17 is 1 + 7 = 8, which is not divisible by 3. This means 17 is not divisible by 3:
17 = 17 (17 is not divisible by 2 or 3)
The last digit of 17 is not 5 or 0, which means 17 is not divisible by 5:
17 = 17 (17 is not divisible by 2, 3 or 5)
Divide 7 into 17:
| | 2 | (quotient)
7 | 1 | 7 |
- | 1 | 4 |
| | 3 | (remainder)
17 is not divisible by 7:
17 = 17 (17 is not divisible by 2, 3, 5 or 7)
The alternating sum of the digits of 17 is 1 - 7 = -6, which is not divisible by 11. This means 17 is not divisible by 11:
17 = 17 (17 is not divisible by 2, 3, 5, 7 or 11)
Divide 13 into 17:
| | | 1 | (quotient)
1 | 3 | 1 | 7 |
| - | 1 | 3 |
| | | 4 | (remainder)
17 is not divisible by 13:
17 = 17 (17 is not divisible by 2, 3, 5, 7, 11 or 13)
No primes less than 17 divide into it. Therefore 17 is prime:
17 = 17
Since 17 is prime it has an exponent of 1:
Answer: 17 = 17^1

The length of a rectangle is 2 m greater than the width. The area is 168 m2 Find the length and the width
Answer:
Length = 14m
Width = 12m
Step-by-step explanation:
The length of a rectangle is 2m greater than the width.
The area of the rectangle = 168m²
Let's say the width is x meters.
The length will be (x + 2) meters.
Area of a rectangle = length × width
x(x + 2) = 168
x² + 2x - 168 = 0
Solving x by applying the quadratic formula we get;
x = 12 or -14
Since the width cannot be negative, we take 12 meters to be the dimensions of the width.
The length = 12 + 2 = 14 meters.
To find the length and width of the rectangle, we formulate an equation based on the known relationship between the dimensions and the given area. Solving the equation, we get the width as 12 m and length as 14 m.
Explanation:The question is about finding the length and width of a rectangle given the area and a relationship between the two dimensions. We can set up an equation based on the information given and the formula for the area of a rectangle. Namely, the area of a rectangle is equal to its length multiplied by its width (A = lw).
According to the problem, the length of the rectangle is 2 m more than the width. We can express this relationship as L = W + 2. We also know that the area of the rectangle is 168 m2, which results in the equation (W + 2)W = 168.
Solving this quadratic equation, we find that the width (W) is 12 m and the length (L) is 14 m. These are the dimensions of the rectangle.

Jim is paid for overtime when he works more than 40 hours per week.
a. Write an expression for the number of hours he works overtime when he works h hours.
b. Find the number of hours Jim works overtime when he works 40, 44, 48, and 52 hours.
Answer:
a. O = h - 40
b. 0, 4, 8, 12
Step-by-step explanation:
Let numver of overtime hours Jim workes for defined by O.
Standard working hours in a week for Jim = 40 Hours
If Jim is working for h hours then number of overtime hours will be given as difference between total hours he worked and standard working hours in a week.
⇒ O = h - 40
now, if jim has worked for 40, 44, 48 and 52 hours then his over time for all these cases will be
O = 40 - 40 = 0 Hours
O = 44 - 40 = 4 Hours
O = 48 - 40 = 8 Hours
O = 52 - 40 = 12 Hours respectively.
Triangles A B C and A double-prime B double-prime C double-prime are shown. Triangle A double-prime B double-prime C double-prime is smaller and to the right of triangle A B C. Which transformations could have taken place to map △ABC to △A"B"C"? a reflection and a dilation a rotation and a dilation a translation and a dilation a reflection and a translation
PLEASE I NEED HELP ASAP
A smaller shape would be a dilation.
A move to the right would be a transition. (As long as the letters for the triangle are in the same orientation).
The answer should be:
A dilation a translation
There are various types of transformations that can be applied to a coordinate point. The new point could become compressed/enlarged, reflected, rotated, etc.
The transformations that transform [tex]\triangle ABC[/tex] to [tex]\triangle A"B"C"[/tex] are a translation and a dilation.
Given that:
[tex]\triangle A"B"C"[/tex] is smaller than [tex]\triangle ABC[/tex]
This means that sides of [tex]\triangle ABC[/tex] were dilated (i.e. compressed) to give the sides of [tex]\triangle A"B"C"[/tex]
Also:
[tex]\triangle A"B"C"[/tex] is at the right of [tex]\triangle ABC[/tex]
This means that [tex]\triangle ABC[/tex] was translated (i.e. shifted) to give [tex]\triangle A"B"C"[/tex]

N is less then 6 units from 0
What is the answer?
The answer would be negative 6 or -6.
Hope this helps!
The values for N can be any number between and including -6 and 6, because the phrase 'N is less than 6 units from 0' signifies absolute distance from zero on the number line.
Explanation:In mathematics, when we say 'N is less than 6 units from 0', we are referring to absolute distance from zero on the number line. That means, N could be any number that falls within the range of -6 to 6, inclusive. This is because the less than 6 units from zero is referring to both directions on the number line. For example, -4 is less than 6 units away from 0, also 5 is less than 6 units away from 0. Thus, the possible values for N are any numbers between and including -6 and 6.

was the interest rate of the account? Round your answer to one decimal place. Do not write the percent sign,
Answer:
The rate of interest was approx 5.64%.
Step-by-step explanation:
The compound interest formula is :
[tex]A=p(1+\frac{r}{n} )^{nt}[/tex]
Here p = 4400
r = ?
n = 1
t = 5
A = 5790

[tex]5790=4400(1+\frac{r}{1} )^{5}[/tex]
=> [tex]5790=4400(1+r )^{5}[/tex]
=> [tex]\frac{5790}{4400} =(1+r )^{5}[/tex]
=> [tex]1.316=(1+r )^{5}[/tex]
=> [tex]1+r=\sqrt[5]{1.316}[/tex]

The amount of rainfall each month over the past four years is shown below
Answer: C
Step-by-step explanation: On Edge 2020
D) The data is symmetrical, showing that the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.
What is Symmetrical Graph?A graph is said to be symmetric about a line if the graph remains unchanged when we reflect the graph on one side of the line to the other side.
Given is a histogram representing the amount of rainfall in the last 4 years or 48 months.
So the graph is symmetrical if we draw a line at the point 3.
Amount of rainfall is 0 - 1 inches for first 11 months. Then it is 1.01 - 2 inches for the next 8 months. Then 2.01 - 3 for the next 5 months and again 3.01 - 4 for the next 5 months. Then it is 4.01 - 5 and 5.01 - 6 for the next 8 years and 11 years respectively.
19 months has the rainfall less than 2.01 inches.
19 months has the rainfall greater than 4 inches.
Only 48 - (19 + 19) = 10 months are having rainfall in between 2.01 and 4.
So majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.

Why would a person choose a PPO over an HMO?
Answer:
With an HMO plan, you pick one primary care physician. All your health care services go through that doctor. That means that you need a referral before you can see any other health care professional, except in an emergency. Visits to health care professionals outside of your network typically aren’t covered by your insurance.
PPO plans give you flexibility. You don’t need a primary care physician. You can go to any health care professional you want without a referral inside or outside of your network.
Staying inside your network means smaller copays and full coverage. If you choose to go outside your network, you'll have higher out-of-pocket costs, and not all services may be covered.
This got me 100% on the assignment!
PPO plans give you flexibility. You don’t need a primary care physician. You can go to any health care professional you want without a referral inside or outside of your network.
Staying inside your network means smaller copays and full coverage.
HMO providers are paid on a per-member basis, regardless of the number of times they see a member.
This makes HMO plans a more economical choice than PPOs. An HMO generally only covers care received from the plan's contracted providers, known as “in-network” providers.
PPO plans generally are more expensive than HMO plans. However, due to the pooling of people in a PPO network, fees associated with health care will be lower for participants.
In other words, you will pay far less for services if you are in a PPO plan vs. not having insurance at all.
So, the person choose a PPO over a HMO.
