The area of a rectangle is found by multiplying the length by the width. So the area of the original rectangle is (6 m) x (9 m) = 54 m^2.
What is the sides of rectangle?If we want to find different side lengths that have the same area, we can keep the area constant and manipulate the length and width.
One way to do this is to multiply the original length by a certain factor and multiply the original width by the reciprocal of that factor.
For example, if we multiply the length by 2 and the width by 1/2, the area will remain the same: (6 m) x 2 = 12 m and (9 m) x (1/2) = 4.5 m. The new rectangle's dimensions would be 12 m x 4.5 m.
Another way to find different side lengths that have the same area is to multiply the original length and width by the same factor.
For example, if we multiply both the length and width by 2, the area will remain the same: (6 m) x 2 = 12 m and (9 m) x 2 = 18 m. The new rectangle's dimensions would be 12 m x 18 m.
So, to draw the rectangle with different side lengths that have the same area, you can use any of the above method, and label the side lengths accordingly.

Answer:
C. Angle Bisector Theorem
x = 5
PO = 34
Step-by-step explanation:
The theorem used is C: Angle bisector theorem
A can be eliminated because there is no midsegment here
B can also be eliminated - no perpendicular bisector
D relates to a median and there is no median here
C is the best choice. You can see in the figure that EO bisects ∠NEP.
Because of this angles ∠NEO and ∠OEP are equal
That makes the triangles congruent since we have one common side and two angles that are equal to each other
Therefore PO = NO
8x - 6 = 6x + 4
8x - 6x = 4 + 6
2x = 10
x = 5
PO = 8(5) - 6 = 40 - 6 = 34
Given the following probabilities for choosing 2 marbles from a bag of 10 marbles, determine if the events are dependent or independent.
P(blue) = 3/10 , P(green) = 1/5 , and P(blue and green) = 3/100
probabilities for choosing 2 marbles from a bag of 10 marbles is Dependent events
Given the following probabilities for choosing 2 marbles from a bag of 10 marbles are:-
P(blue) = 3/10, P(green) = 1/5, P(blue and green) = 3/100
We know the fact that two event are independents if we have following:-
P(X and Y) = P(X) times P(Y)
For this problem, we must have P(blue and green) = P(blue) times P(green).
P(blue and green) = (3/10) * (1/5) = 3/50
But given P(blue and green) = 3/100
Since we have 3/100 ≠ 3/50
Hence, the events are not independent events.
So, they are dependent events.

shown below is a regular octagon. each of the four red regions has area $12$. what is the area of the blue region?
Area of the blue region = A - B = (2+ 2*√(2))/2 * (side length)^2 - 48 square units.
What is the area of congruent right triangles?
Two right-angled triangles are said to be congruent to each other if the hypotenuse and one side of the right triangle are equal to the hypotenuse and the corresponding side of the other right-angled triangle.
The blue region is a square, and the four red regions are congruent right triangles.
The blue square is formed by connecting the midpoints of the four sides of the octagon. Since it is an octagon, each of its angles is 135 degrees, and the four red regions are 45-45-90 triangles.
Thus the area of the blue region is equal to the area of the square which is (side length)^2.
The four red regions have a combined area of 124 = 48 square units.
Since the octagon is a regular polygon, all its sides are congruent.
The area of the octagon can be found by multiplying the square of the length of one side by (2+ 2√(2))/2.
If we call the area of the octagon A, and the area of the four red regions B then:
A = B + 4 * 12
Now we can solve for the area of the blue region (A - B)
Area of the blue region = A - B = (2+ 2*√(2))/2 * (side length)^2 - 48 square units
Since we know the area of the red regions we can find the area of the blue region.
Hence, the Area of the blue region = A - B = (2+ 2*√(2))/2 * (side length)^2 - 48 square units.

Kevin hiked up Lamb's Canyon in 3 hr and then ran back down in 2 hr. His speed running downhill was 1.8 mph greater than his speed hiking uphill. How far up the canyon did he hike?
Kevin hiked (blank) mi up the canyon.
Kevin hiked up Lamb's Canyon with the goal of making it to the top.
How far up the canyon did he hike?To solve it, you need to set up two equations - one for hiking and one for running.Let x be the distance Kevin hiked up the canyon.
For hiking: 3 hr = x / h
For running: 2 hr = (x + 1.8) / r
Where h is the speed at which Kevin hiked uphill and r is the speed at which he ran downhill.Solving the two equations for x yields:
x = (3h * r) / (h + r)
To find the distance Kevin hiked up the canyon, you need to plug in the values for h and r.Therefore, Kevin hiked (3h * r) / (h + r) mi up the canyon.
For the distance that Kevin hiked uphill, the equation would look like this:Distance = (x mph) * (3 hr)
For the distance that Kevin ran downhill, the equation would look like this:Distance = (x + 1.8 mph) * (2 hr)
We can combine these two equations by setting them equal to each other and solving for x. We get:(x mph) * (3 hr) = (x + 1.8 mph) * (2 hr)
Solving for x, we get x = 2.4 mph.
Now that we know x, we can plug it back into our original equation for the distance that Kevin hiked uphill. We get:Distance = (2.4 mph) * (3 hr) = 7.2 mi. Therefore, Kevin hiked 7.2 mi up the canyon.To learn more about to find the distance refer to:

The Gini coefficient, commonly referred to as the Gini index or Gini ratio, is a measure of demographic distribution used in economics to estimate the average income of a population. The most often used method for estimating inequality is the Gini coefficient.
The Italian statistician and sociologist Corrado Gini is honoured as the creator of the Gini Coefficient.
If everyone has the same wealth or income, then a Gini coefficient of 0 implies complete equality, whereas a value of 1 indicates perfect inequality (that is, where one person owns all the wealth in a country).
For most nations, the value actually ranges between 0 and 1. It would be close to 1 in nations with significant levels of inequality.

The sum of two numbers is 71. The second number is 6 more than 4 times the first number. What are the two numbers?
We can start solving the problem by using algebra. Let's call the first number x and the second number y. From the problem statement, we know that:
y = 4x + 6 (because the second number is 6 more than 4 times the first number)
x + y = 71 (because the sum of the two numbers is 71)
We can substitute the first equation into the second equation:
x + (4x + 6) = 71
5x + 6 = 71
5x = 65
x = 13
Now that we know the value of x, we can substitute it back into the first equation to find the value of y:
y = 4(13) + 6
y = 54
So the two numbers are 13 and 54.

What is the domain and range of function?
A function's domain and range are its components. A function's range is its potential output; its domain is the set of all conceivable input values. Domain, Function, and Range. If a function f: A B exists that maps every element in A to an element in B, then A is the domain and B is the co-domain. The image of an element 'a' under a relation R is provided by 'b,' where (a,b) R. The set of photographs makes up the function's range.
From the graph, the value of x varies from The x-values -7, -2, 5, and 7
So the domain of the function will be
0≤x≤7
Hence, the domain of the function 0≤x≤7.

transponder for a toll bridge costs $22.50. With the transponder, the toll is $4 each time you cross the bridge. The only other option is toll-by-plate, for which the toll is $5.25 each time you cross the bridge with an additional administrative fee of $1.25 for each crossing. How many times would you need to cross the bridge for the costs of the two toll options to be the same?
You need to cross the bride _ times?
Using linear function you would need to cross the bridge 30 times for the costs of the two toll options to be the same.
What is meant by linear function ?To find out how many times you would need to cross the bridge for the costs of the two toll options to be the same, we need to set up an equation.Let x be the number of times you need to cross the bridge.For the transponder option: 22.50 + 4x = costFor the toll-by-plate option: 5.25x + 1.25x = costSince the costs of the two options need to be equal, we can set the two equations equal to each other and solve for x:22.50 + 4x = 5.25x + 1.25x + 22.504x = 5.25x + 1.25x0.75x = 22.50x = 30So you would need to cross the bridge 30 times for the costs of the two toll options to be the same.To learn more about linear function refer:

The statistics class was where the data were gathered. The variable is indicated by the column headers, along with each row's Eye Shoe Height 9.
Is the variable handedness numerical or categorical?5 different variables are present. Category-specific characteristics include gender, handedness, and field side. Quantitative factors include height and the distance covered when walking. Numbers are used to express variables like the number of siblings and student height. It is discrete since it is a count of siblings. As a continuous numerical variable, height varies throughout time.
There are three primary types of variables: controllable, dependent, and independent. His realization that shoe size is an interval variable came later. Eureka! There is no zero point in an interval variable, but there is a defined range between values. If we take shoe sizes into consideration,
we can conclude that the difference between
a size 2 and a size 3 = size 8 - a size 7
Two major categories—categorical and numeric—can be used to group variables.

During the past year, Mrs. Singh purchased 29 books at a wholesale club store. She purchased softcover books for $3.50 each and hardcover books for $11.50
each. The total cost of the books was $205.50. How many of each type of book did she purchase?
Part 1 of 2
Mrs. Singh purchased (blank) softcover books
Part 2 of 2
Mrs. Singh purchased (blank) hardcover books.
Answer:
Step-by-step explanation:
Let's assume the number of soft-cover books Mrs. singh purchased as y.
let's assume the number of hard-cover books Mrs. singh purchased as x.
Total number of books purchased = 29 (given)
i.e. (hardcover books) + (softcover books) = 29
x + y = 29 ........................(i)
Total amount spent on books = Rs.205.50
i.e. (cost of hardcover books) + (cost of softcover books) = 205.50
(price * no. of hardcover books) + (price * no. of softcover books) = 205.50
(11.50*x) + (3.50*y) = 205.50 ......................(ii)
from eq(i),
we find x,
x = 29-y
putting the value of x in eq(ii),
(29-y)11.50 + 3.50y = 205.50
333.50 - 11.50y + 3.50y = 205.50
8y = 128
y = 16
so, x = 29 - 16 = 13
Therefore, the number of soft cover books purchased by Mrs. Singh is 16 and the number of hardcover books purchased by Mrs. Singh is 13.
