Answer: It is because if ∠N and ∠K are congruent and are same in size and shape.
Answer:
KLM is equal to NLM because in order to share a bisector, they have to have the same length. Also we can assume that <L and <M are the same since they share the same vertex, making both triangles equal.

In the diagram below of triangle KLM, N is a midpoint of KL and P is a midpoint
of LM. If mZPNL = 2x + 61, and MKN = 97 - 7x, what is the measure of
ZPNL?
Answers
Answer:
Solution:
(1/12)^(-2b) * 12^(-2b+2) = 12
(12^-1)^(-2b) (12)^(-2b+2) = 12
(12^2b)(12)^(-2b+2) = 12
12^(2b-2b+2) = 12
12^2 = 12
144 does not equal 12
No solution.
Step-by-step explanation:
The measure of angle PNL will be equivalent to 69 degrees.
What is triangle?A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
The sum of two sides of a triangle is greater then the third side. Mathematically -
a + b > c
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given is a triangle KLM such that N is a midpoint of KL and P is a midpoint of LM.
Triangles LMP and LKM are similar to each other. Therefore, PN will be parallel to MK. So angle PNL will be equal to angle MKN. Therefore -
2x + 61 = 97 - 7x
9x = 97 - 61
9x = 36
x = 4
So, angle PNL will be equal to -
2 x 4 + 61
69 degrees
Therefore, the measure of angle PNL will be equivalent to 69 degrees.

What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as it's degree is two.
We know the graph of a quadratic equation ax² + bx + c is a parabola that opens upwards and is symmetrical about the y-axis.
Given, a parabola f(x) = 2x² - 5x + 3.
Now it is changed to f(x) = 2x² - 5x + 1 which also can be written as,
f(x) = 2x² - 5x + 3 - 2, So it has been translated 2 units down along the y-axis.

If 1/5 of the money in a cash box is 30 dollars, how much money is in the cash box?
Answers
Answer:
Money in the cash box is $150
Step-by-step explanation:
Let
x = money in the cash box
1/5 of the money in a cash box is 30 dollars
1/5 of x = $30
1/5 * x = 30
1/5x = 30
Divide both sides by 1/5
x = 30 ÷ 1/5
= 30 × 5/1
= 150/1
x = $150
Money in the cash box is $150

In an algebraic expression what is the product of 15 and c
Answers
Answer:
15c
Step-by-step explanation:
15 multiplyed by c gives 15c
In an algebraic expression, the product of 15 and c can be represented as 15c.
The term "product" refers to the result of multiplying two or more numbers or variables together. In this case, we are multiplying the number 15 by the variable c.
The expression 15c represents 15 multiplied by the value of c. It can be thought of as 15 times an unknown value represented by c. The variable c can represent any real number or algebraic expression, depending on the context of the problem or equation.
For example, if c is equal to 2, then the product 15c would be equal to 15 multiplied by 2, resulting in 30. Similarly, if c is equal to -3, then the product would be -45 since multiplying 15 by -3 gives -45.

Walter is planning a hiking trip and he estimated the gradient of trail to be 213.6 ft/mile. After hiking and tracking the trail, he found that the trail was actually 202.7 ft/mile. What was his percent error? Did he overestimate or underestimate the gradient?
Answers
Answer: His percent error = 5.38 %
He overestimated the gradient.
Step-by-step explanation:
Formula : [tex]Percent\ error =\dfrac{|Estimated\ value- Actual\ value|}{Actual\ value}\times100[/tex]
Given, Estimated gradient of trail = 213.6 ft/mile
Actual gradient of trail = 202.7 ft/mile
Since, 213.6 > 202.7 , that means he overestimated the gradient.
Percent error: [tex]\dfrac{|213.6-202.7|}{202.7}\times100[/tex]
[tex]=\dfrac{10.9}{202.7}\times100\\\\\approx5.38\%[/tex]
Hence, percent error = 5.38 %

A scale drawing of a school bus has a scale of 1 inch to 5 feet. If the length of the school bus is 6 inches on the scale drawing, what is the actual length of the bus? Explain or show your reasoning. *
Answers
Answer: 30 Feet
Step-by-step explanation:
In Technical drawings scales are used to reduce the size ( scaling ) of drawings so they fit in our drawing sheets. in this example above the drawer stated that 1inch was representing 5feet. what this means is that because we can’t get a drawing sheet which would be 40-100 feet wide we need to rescale our drawing to fit into the available sheet. So by saying 1inch equals 5feet this means the school bus is 30Feet in length.

Answers
Answer:
Hey there!
Consecutive integers mean that the numbers are next to each other.
Consecutive even integers mean that the numbers are separated by a number between them.
Thus, if x is the smaller number, x+2 can be used to write the larger number.
x+x+2=1594
2x+2=1594
2x=1592
x=796.

-5(4x-2) = -2(3+6x)
what is the answer and how do you get it
Answers
Answer:
x = 2
Step-by-step explanation:
-5(4x - 2) = -2(3 + 6x)
-20x + 10 = -6 - 12x Distribute -5 to 4x and -2 and distribute -2 to 3 and
6x
10 = -6 + 8x Add 20x to both sides
16 = 8x Add 6 to both sides
2 = x Divide 8 to both sides
Answer:
-0.5
Step-by-step explanation:
-5(4x-2) = -2(3+6x)
-20x-10 = -6-12x
-10 = -6+8x

Answers
Answer:
1,000 friends will get 1 gram of gold bar each from 1 kilogram of gold bar
Step-by-step explanation:
1 kilogram of gold bar = 1,000 grams of gold bar
You have 1 kilogram of gold bar
You want each of your friends to get 1 gram
Number of friends that will get 1 gram of gold bar each = 1 kilogram of gold bar / 1 gram
= 1000 gram / 1 gram
= 1,000
Number of friends that will get 1 gram of gold bar each = 1,000 friends
