What is rectangle?
A rectangle in Euclidean plane geometry is a quadrilateral with four right angles. You might also describe it as follows: a quadrilateral that is equiangular, which indicates that all of its angles are equal. The parallelogram might also have a straight angle. Squares are rectangles with four equally sized sides. A quadrilateral of the shape of a rectangle has four 90-degree vertices and equal parallel sides. As a result, it is sometimes referred to as an equirectangular rectangle. Because its opposite sides are equal and parallel, a rectangle is also known as a parallelogram.
Given that the length of the rectangular space is three times its breadth
The chamber has a 56-meter perimeter.
Assume that the room's width is x.
As a result, the room is three times as long.
The room's perimeter is now equal to 2(3x + x).
[tex]Here, 2(3x + x) = 56\\ 2 * 4x = 56\\ 8x = 56\\ x = 7.[/tex]
Consequently, the room has a 7 meter width.
The room's length is

Moussa's age if the product of their ages is 24 is 4 years.
How to calculate their age?An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario.
Moussa is younger than Sophia. Their ages are consecutive even integers.
Let the ages be x and x + 2.
This will be illustrated as:
x(x + 2) = 24
x² + 2x = 24
x² + 2x - 24 = 0
x² + 6x - 4x - 24 = 0
x(x + 6) -4(x + 6) = 0
x - 4 = 0
x = 4

If the product of Sophia age and Moussa age is 24, the age of Moussa is 4 years.
How to find the Moussa's age?Moussa is younger than Sophia. Their ages are consecutive even integers.
The product of there ages is 24. Moussa's age can be found as follows:
Even numbers are those numbers that can be divided into two equal groups or pairs and are exactly divisible by 2.
Hence,
Let
x = age of Moussa
x + 2 = age of Sophia
Hence, the product of their age will be as follows:
x(x + 2) = 24
x² + 2x = 24
x² + 2x - 24 = 0
lets factorise the quadratic equation. The numbers one can multiply to get -24 and add to get 2 are -4 and 6. Therefore,
x² - 4x + 6x - 24 = 0
x(x - 4) + 6(x - 4) = 0
(x + 6)(x - 4) = 0
Therefore,
x = - 6 and x = 4
We can only use positive numbers.
Therefore, the age of Moussa is 4 years

Elie built a large rectangular vegetable garden that i 9 meter long and ha an area of 72 quare meter. What i the perimeter of Elie’ vegetable garden
Answer:
The perimeter of Elie's vegetable garden is 34 meters.
Step-by-step explanation:
The formula for area is: a=w*l.
A = area
W = width
L = length
If the length is 9 meters, then we know two of the values, the area, and the length. Substitute.
72=w*9
You can divide both sides by 9 to get the width, which is 8 meters.
To find perimeter, we add l+w+l+w, or 2l+2w. Substitute for our values:
2(9)+2(8)=34
The perimeter of Elie's vegetable garden is 34 meters.

After the end of the lease period the pay, the rent would increase to $3030.83 approx.
What is a Lease agreement?A lease is a legal agreement by which the owner of a building, a piece of land, or something such as a car allows someone else to use it for a period of time in return for money.
Given here, a 2-year lease is - $2,657 per month plus a $200 security deposit. Now, the average increase in the rate in the U.S is 14.07%
thus, at the end of the two-year lease period, the new rent would be
= (1+14.07/100) × $2,657
= $3030.83
Hence, the new rent with a security deposit is $3030.83 + security deposit.

The tatue i 4. 6 meter high. The angle of elevation from the oppoite corner of the courtyard to the top of the tatue i 8
The statue is 4. 6 meter high. The angle of elevation from the opposite corner of the courtyard to the top of the statue is 8,Tan 8 = 4.6/opposite and opposite = 4.6/tan 8 = 5.8 meters
First, we calculate the opposite side of the triangle using the tangent function. To do this, we need to use the angle of elevation (8 degrees) and the height of the statue (4.6 meters). We use the tangent function to calculate this, which is written as:
tan 8 = 4.6/opposite
Solving for the opposite, we get:
opposite = 4.6/tan 8 = 5.8 meters
This means that the opposite corner of the courtyard to the top of the statue is 5.8 meters away.

Store A sells a dozen donuts in packages as a BOGO, with the regular price of dozen at $6.35. Store B offers a dozen donuts without a special for $3.35. Store C offers a dozen and a half at a price of $6.50. Store D gives you a 25% discount if you buy 2 at a price of $3.70 each. Which is the better buy?
Store D provides the best value, with the lowest price per donut at $0.24.
To determine which store has the best deal, you should compare the price per donut at each store.
At Store A, the BOGO offer means that you can buy one dozen donuts for the regular price of $6.35 and get a second dozen for free. This means that you are paying $6.35 for 2 dozen donuts, or $0.27 per donut.
At Store B, a dozen donuts cost $3.35, or $0.28 per donut.
At Store C, a dozen and a half donuts cost $6.50, or $0.26 per donut.
At Store D, if you buy 2 dozen donuts at $3.70 each and receive a 25% discount, you will pay $3.70 × 2 × (1 - 0.25) = $5.77 for 2 dozen donuts, or $0.24 per donut.
Thus, based on these prices, Store D is the best deal, as it has the lowest price per donut at $0.24.

here is a famous problem: nn guests arrive at a party. each person is wearing a hat. we collect all hats and then randomly redistribute the hats, giving each person one of the nn hats randomly. what is the probability that at least one person receives his/her own hat?hint: use the inclusion-exclusion principle.
The probability that at least one person receives his/her own hat is 1 - (1/n)^n, using the inclusion-exclusion principle.
The inclusion-exclusion principle states that the probability of event A or B occurring is equal to the probability of event A plus the probability of event B minus the probability of event A and B occurring. In this case, the probability of at least one person receiving his/her own hat is the probability of one person receiving his/her own hat plus the probability of two people receiving their own hats minus the probability of three people receiving their own hats, and so on. This can be expressed mathematically as 1 - (1/n)^n, where n is the number of guests. This formula can be applied to any situation where a random event is being repeated multiple times with the same set of outcomes.1 - (1/10)^10 = 0.99.

Each year the value of a car decreases by 12% of its value at the beginning of that year. The original value of the car is $20000. Calculate the value of the car at the end of 3 years
Answer:
The value of the car at the end of 3 years will be $13707.
Step-by-step explanation:
If the original value of the car is $20000, then after the first year, the value of the car will be $20000 - (12/100)*$20000 = $17600.
After the second year, the value of the car will be $17600 - (12/100)*$17600 = $15552.
After the third year, the value of the car will be $15552 - (12/100)*$15552 = $13707.
Therefore, the value of the car at the end of 3 years will be $13707.

Graph the following system of equations.
2x + 4y = 8
2x + 6y = 18
What is the solution to the system?
There is no solution.
There is one unique solution, (−6, 5).
There is one unique solution, (−4, 4).
There are infinitely many solutions.
Answer:
There is one unique solution, (−6, 5).
Step-by-step explanation:
2x + 4y = 8
2x + 6y = 18
2x + 4y = 8 ==> solve for 2x
2x + 4y - 4y = 8 - 4y
2x = 8 - 4y
2x + 6y = 18 ==> solve for 2x
2x + 6y - 6y = 18 - 6y
2x = 18 - 6y
8 - 4y = 18 - 6y ==> 2x = 8 - 4y and 2x = 18 - 6y
8 - 4y + 6y = 18 - 6y + 6y ==> solve for y by first adding 6y on both sides to
remove negative y
8 + 2y = 18 ==> simplify
8 - 8 + 2y = 18 - 8 ==> isolate y
2y = 10
y = 5
2x + 4(5) = 8 ==> substitute 5 for y in 2x + 4y = 8
2x + 20 = 8
2x - 20 + 20 = 8 - 20 ==> subtract 20 on both sides to isolate 2x
2x = -12
x = -6
x = -6, y = 5 ==> (6, 5)
Answer: There is one unique solution, (−6, 5).

Ma Amati’s bought x number of shirts for the new members of the dance team. The total amount paid for x shirts, including $2.99 shipping, was $118.99. Each shirt cost $14.50. There was no sales tax on this purchase. Which equation could be used to find x, the number of shirts bought
Answer: y = 14.50x + 2.99
Step-by-step explanation:
The equation is y = mx + b
y is the total cost and x is the number of shirt
We know each shirt is $14.50, and she bought x shirts, so 14.50 is the slope
The 2.99 shipping fee is the y-intercept
So our equation is
y = 14.50x + 2.99
