The midpoint and length of the points J(4,3) and K(2,-3) is calculated as (1,0) and 40.
The midpoint and length of the points L(-4,5) and N(5,-3) is calculated as (-12,1) and 145.
Given : The endpoints J(4,3) and K(2,-3) and L(-4,5) and N(5,-3)
We need to find the midpoint and length of these endpoints.
The formula for midpoint is x1+x22, y1+y22
From the first endpoints, x1=4 , y1=3 , x2=2 , y2=-3
4+22, 3-32 => (22,02) => (1,0)
So, the midpoint for the endpoints is (1,0)
The formula to find the length is (x2-x1)2+(y2-y1)2
From the first endpoints , the length becomes
(2-4)2+((-3)-3)2=> (-2)2+(-6)2 => 4+36 => 40
The formula for midpoint is x1+x22, y1+y22
From the first endpoints, x1=-4 , y1=5 , x2=5 , y2=-3
-4+52, 5-32 => (-12,22) => (-12,1)
So, the midpoint for the endpoints is (-12,1)
The formula to find the length is (x2-x1)2+(y2-y1)2
From the first endpoints , the length becomes
(5+4)2+((-3)-5)2=> (9)2+(-8)2 => 81+64 => 145
Hence, the midpoint and the length from the endpoints is calculated and determined.

You want to make 20 plates and have 30 bags of shredded cheese. How can you determine how much cheese to put on each plate so that each plate has the same amount of shredded cheese?
The amount of cheese in each plate = 1.5x
There are 30 bags of shredded cheese.
Let 'x' be the quantity of cheese in each bag. Then,
The total quantity of cheese in 30 bags = 30x
Number of plates = 20 plates
We need to determine the quantity of cheese put on each plate so that each plate has the same amount of shredded cheese.
For this we just need to divide the total amount of shredded cheese by the number of plates.
The equal amount of cheese in each of 20 plates = 30x/20
= 3x/2
= 1.5x

What are the coordinates of the point on the
directed line segment from (4, 3) to (9, 8) that
partitions the segment into a ratio of 2 to 3?
The required coordinates are (6, 5).
Let A denotes the point (4, 3), and B denotes the point (9, 8).
Let C denote the point which divides the line segment AB in the ratio of 2:3.
The distance between A(4, 3) and B(9, 8) is given by
AB = √{(x₂ - x₁)² + (y₂ -y₁)²}
= √{(9 - 4)² + (8 - 3)²
= √{5² + 5²}
= √(2×5²)
= 5√2
We have AC + BC = AB
AC and BC are in the ratio 2:3.
Therefore 2x + 3x = AB
⇒5x = 5√2
⇒x = √2.
Therefore, AC = 2√2 and BC = 3√2.
Using the distance formula,
AC = √{(x - 4)² + (y - 3)²}
⇒ 2√2 = √{(x - 4)² + (y - 3)²}
⇒ √(2² + 2²) = √{(x - 4)² + (y - 3)²} (taking the 2 inside the square root.)
⇒ x - 4 = 2 ⇒ x = 6
⇒ y - 3 = 2 ⇒ y = 5.
Therefore the required coordinates are (6, 5).

Standard deviation is a statistical measure of how much scores in a sample vary around the mean. The correct option is B.
What is the standard deviation?The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.
Therefore, the standard deviation is a statistical measure of how much scores in a sample vary around the mean. The correct option is B.

a fishing boat accidentally spills 15 barrels of diesel oil into the ocean. each barrel contains 42 gallons. if the oil film on the ocean is 2.5×102nm thick, how many square meters will the oil slick cover?
The square meters of the area the oil slick will cover is 9.6 × 10⁶ m².
What is meant by volume?Volume is defined as the amount of three-dimensional space enclosed by a closed surface.
The liter (L) is the metric system's base volume unit, with several extended volume units also available. There are also many metric volume units based on the a cubic length dimension, including such cubic meters or cubic centimeters. Gallons and ounces are examples of imperial volume units.Now, as per the given question;
First, we determine the entire volume of oil in gallons by multiplying the volume per barrel even by total number of barrels:
15×42 gal = 630 gal
This volume must be converted to square meters:
V = 630 gal × (0.00379 m³/ gal
V = 2.4 m³
The thickness (height) of a oil film in meters is required:
h = 250 nm × (m/10⁻⁹nm)
h = 2.5 × 10⁻⁷m
The surface area of a oil film is calculated by dividing the oil volume by height of the oil film.
A = V/h
A = 2.4 m³/2.5 × 10⁻⁷m
A = 9.6 × 10⁶ m²
Therefore, the area of the oil slick cover is found to be 9.6 × 10⁶ m².

find the perimeter of the polygon with vertices U (-2,4) V (3,4) and W (3,-4)
So the perimeter of the polygon with vertices U (-2,4) V (3,4) and W (3,-4) is Perimeter = 22.434
Perimeter of any close shape is the total length of the boundary of any closed shape.
We have been given vertices of polygon that are U (-2,4) V (3,4) and W (3,-4)
To find the perimeter we need to find the length of all three sides, and we do that by finding the distance between the points that form the sides:
The formula for the distance between two points is:
[tex]$d=\sqrt{\left(x_1-x_2\right)^2+\left(y_1-y_2\right)^2}$[/tex]
side UV:
[tex]$U V=\sqrt{(-2-3)^2+(4-4)^2}=5$[/tex]

The solution to a system of equations is (2,-4).one equation in the system is 2x+y=0.explain how you can find a second equation for the system.then find a second equation.solve by system of equations to justify your answer
The second equation is 3x + y = 2.
Let the other equation be of the form ax + by = c, where a, b and c are constants.
Given equation is 2x + y = 0
We have, a₁ = 2 and a₂ = 1
And b₁ = a and b₂ = b
Since, both equations have a unique solution,
∴ a₁ ÷ b₁ ≠ a₂ ÷ b₂
2 ÷ a ≠ 1 ÷ b
2b ≠ a … (1)
Also, (2, -4) is the solution of the equations, so it will satisfy the equations
2a - 4b = c
b = (2a - c)/4
Let c=2
b = (2a - 2) ÷ 4
b = 1
Now we can take any value for a and b which satisfy eq.(1)
Let a=3
b = (2(3) - 2) ÷ 4
b = 1
Thus, a = 3 and b=1 satisfy eq.(1)
Hence the second equation is 3x + y = 2
The equations are justified by keeping the values -
2x+y=0 ... (2)
3x+y=2 ... (3)
From eq.(2),
y=-2x
Putting value of y in eq. (3), we get,
3x+(-2x)=2
3x-2x=2
x=2
Now, putting x=2 in eq.(2)
2(2)+y=0
y=-4
Hence, the solution is justified.

When the same number is added to the numerator and denominator of 5/7, the result is 17/23. what is that number?
The number added to the numerator and the denominator is 2/3.
It is given in the question that when the same number is added to the numerator and denominator of fraction 5/7, the result is 17/23.
We have to find the number added to the numerator and the denominator.
Let the number be x.
Hence, according to the data given in the question, we get,
(5 + x)/(7 + x) = 17/23
By cross - multiplication, we get
23(5 + x) = 17 (7 + x)
Opening the bracket according to the distributive property of addition and multiplication, we get,
