The perimeter of the polygon with the vertices L = (1, 4), P = (-1, -2),
N = (2, 0) and M = (4, 0) is approximately 17.93 units.
We have,
The polygon has the following sides:
LP, PN, NM, and ML.
The coordinates for each point are:
L = (1, 4)
P = (-1, -2)
N = (2, 0)
M = (4, 0)
The perimeter of the polygons.
= LP + PN + NM + ML
Using the distance formula for the distance between two points (a, b) and (c, d):
Distance = √((c - a)² + (d - b)²)
Let's calculate the distances between the points:
LP:
Distance(LP)
= √((-1 - 1)² + (-2 - 4)²)
= √((-2)² + (-6)²)
= √(4 + 36)
= √40
= 6.32
PN:
Distance(PN)
= √((2 - (-1))² + (0 - (-2))²)
= √((2 + 1)² + (0 + 2)²)
= √(3² + 2²)
= √(9 + 4)
= √13
≈ 3.61
NM:
Distance(NM)
= √((4 - 2)² + (0 - 0)²)
= √(2² + 0²)
= √4
= 2
ML:
Distance(ML)
= √((4 - 1)² + (0 - 4)²)
= √((4 - 1)² + (-4)²)
= √(3² + 16)
= √(9 + 16)
= √25
= 5
Now,
Perimeter = LP + PN + NM + ML
Perimeter ≈ 6.32 + 3.61 + 2 + 5 ≈ 16.93
Thus,
The perimeter of the polygon is approximately 17.93 units.

How do you find the measure of angle A?
Answer:
m∠A = 18
Step-by-step explanation:
Formula:
the sum of the interior angles of a triangle is 180.
____________________
According to the formula :
[tex]m\angle A\ +\ m\angle B\ +\ m\angle C=180[/tex]
⇔ x - 22 + 3x + 19 + x - 17 = 180
⇔ 5x + (19 - 17 - 22) = 180
⇔ 5x + (2 - 22) = 180
⇔ 5x - 20 = 180
⇔ 5x = 180 + 20
⇔ 5x = 200
[tex]\Leftrightarrow x = \frac{200}{5} \\\Leftrightarrow x = 40[/tex]
Conclusion:
m∠A = x - 22 = 40 - 22 = 18

6-8x=7x-9x-36 i really need help
Answer:
Simplifying
6 + -8x = 7x + -9x + -36
Reorder the terms:
6 + -8x = -36 + 7x + -9x
Combine like terms: 7x + -9x = -2x
6 + -8x = -36 + -2x
Solving
6 + -8x = -36 + -2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2x' to each side of the equation.
6 + -8x + 2x = -36 + -2x + 2x
Combine like terms: -8x + 2x = -6x
6 + -6x = -36 + -2x + 2x
Combine like terms: -2x + 2x = 0
6 + -6x = -36 + 0
6 + -6x = -36
Add '-6' to each side of the equation.
6 + -6 + -6x = -36 + -6
Combine like terms: 6 + -6 = 0
0 + -6x = -36 + -6
-6x = -36 + -6
Combine like terms: -36 + -6 = -42
-6x = -42
Divide each side by '-6'.
x = 7
Simplifying
x = 7

Express -48 by 60 as a rational number with denominator 25 pura Karen
Answer:
-20/25
Step-by-step explanation:
To change a fraction to one with a different denominator, common factors can be removed or added to numerator and denominator as required.
__
-48/60 can be reduced to lowest terms by removing the common factor of 12. It can be made to have a denominator of 25 by adding a common factor of 5.
[tex]-\dfrac{48}{60}=-\dfrac{4\cdot12}{5\cdot12}=-\dfrac{4}{5}\\\\=-\dfrac{4\cdot5}{5\cdot5}=\boxed{-\dfrac{20}{25}}[/tex]
__
Alternatively, the numerator of the desired fraction can be found by multiplying the given fraction by the desired denominator.
numerator = 25×(-48/60) = -1200/60 = -20
new fraction = -20/25

Answer:
904.8 units^3
Step-by-step explanation:
The formula for the area of a circle is [tex]4/3 \pi r^3[/tex]
By the picture we know r = 6
Thus our answer is 4/3 * π * [tex]6^3[/tex]
This is the same as 4/3 * 216 * π = 904.778684234
Rounding to the nearest tenth yields 904.8 units^3
Find the median of the data.
24,74,61,29,38,27,68,54
Answer:
The median is 46
Step-by-step explanation:
To find the median, you must first order the numbers, from left to right, lowest to highest:
24, 27, 29, 38, 54, 61, 68, 74
Next, we have to find the number in the middle. We can do this by counting inwards one and crossing out each of the lowest and highest each time we get closer to the middle/center.
24, 27, 29, 38, 54, 61, 68, 74
, 27, 29, 38, 54, 61, 68,
, , 29, 38, 54, 61, ,
, , , 38, 54, , ,
Now, if there is no exact middle, we would add them add divide by 2. If there was an exact middle, that would be the answer. But there isn't.
38 + 54 = 92
92 / 2 = 46
The median is 46

inches. This is (18.84, 9.42, 37.68, 12.57)
inches less than the circumference of the new container.
The circumference of the original container is 12.57 inches.
The cirucmference of the original container is 12.57 inches less than the circumference of the new container.
What is the circumference of the cylinder?The circumference of a cylinder is the distance round the cylinder. It is the perimeter of the cylinder.
The circumference of a cylinder = πD
Where:
π = 22/7D = diameterThe circumference of the original container = 22/7 x 4 = 12.57 inches
The circumference of the family sized container 12.57 x 2 = 25.14 inches
Difference in the circumference = 25.14 - 12.57 = 12.57 inches

of 60° with the ground. Find the distance from the house to the
foot of the ladder.
A 13 feet
)
B 7.5 feet
C 10 feet
D
8.2 feet
Answer:
B
Step-by-step explanation:
assume a right angle between the house and the ground.
then the ladder is the hypotenuse and distance from ladder to house is d
using the cosine ratio in the right triangle and the exact value
cos60° = [tex]\frac{1}{2}[/tex] , then
cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{d}{15}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2x = 15 ( divide both sides by 2 )
x = 7.5
distance from house to foot of ladder is 7.5 feet
