Two polygons are similar if and only if there is a correspondence among their angles and among their sides so that all corresponding angles are congruent and all corresponding sides are proportional.
Two polygons are said to be similar if they have the same shape, but not the same size. A polygon is any two-dimensional closed shape with straight lines. Similar polygons have the same number of sides and angles. The sides of the similar polygons are proportional to the corresponding sides of the other polygon.
The ratio of their corresponding sides is the same as the ratio of their perimeter. The angles of the similar polygons are congruent to the corresponding angles of the other polygon. The ratio of their corresponding angles is the same as the ratio of their measure.
The corresponding sides and angles are the ones that match between the two polygons. In other words, they are the sides and angles that are in the same position in the two polygons. For example, side AB in polygon ABC corresponds to side DE in polygon DEF. Angle A in polygon ABC corresponds to angle D in polygon DEF.

3/5 kilogram of soil fills 1/3 of a container can 1 kilogram of soil fit
in the container
1 kilogram of soil will fit in the container, since 1 kilogram is less than 27/5 kilograms.
What is the fraction of 1 kg soil in the container?
We can start by using ratios to solve this problem.
From the information given, we know that:
3/5 kilogram of soil fills 1/3 of the containerWe want to know how much soil will fit in the entire container (which is equivalent to 3 times the amount that fills 1/3 of the container)
To find out how much soil fills the entire container, we can set up a ratio:
(3/5 kg of soil) : (1/3 of container) = (x kg of soil) : (1 container)
We can cross-multiply to solve for x:
(3/5 kg of soil) * (1 container) = (1/3 of container) * (x kg of soil)
Multiplying both sides by 3/1 gives:
(3/5) * 3 * (1 container) = (1/3) * x
Simplifying gives:
9/5 = 1/3 * x
Multiplying both sides by 3 gives:
27/5 = x

The couple asked the architect to add a square garden shed to the plans that she
drew. She added a square garden shed with coordinates (-2,8), (1,8), (1, 11), and
(-2, 11) to the plans. Discuss the following with a partner:
• How could you find the perimeter and area of the shed without graphing
the coordinates?
• How is this problem different from finding the perimeter and area of the
base of the house?
. Can you use the same strategy to solve both problems? Why or why not?
Answer:
To find the perimeter and area of the square garden shed without graphing the coordinates, you can use the distance formula to calculate the length of one side of the square. The distance formula is d = √((x2 - x1)^2 + (y2 - y1)^2), where (x1, y1) and (x2, y2) are the coordinates of two points. Using this formula with the coordinates of two adjacent corners of the square, such as (-2,8) and (1,8), we find that the length of one side of the square is 3 units. Since all sides of a square are equal in length, the perimeter is 4 times the length of one side, or 12 units. The area of a square is equal to the length of one side squared, so the area of the square garden shed is 9 square units.
This problem is different from finding the perimeter and area of the base of a house because it involves a square shape rather than a more complex shape. However, you can use similar strategies to solve both problems by calculating distances between points and using geometric formulas to find perimeter and area. The specific formulas used may vary depending on the shape of the base of the house.

Polynomial multiplication is the process of multiplying two polynomials together to get a new polynomial that represents the product of the two original polynomials.
What is Polynomial multiplication?It should be noted that to multiply two polynomials, you need to perform a distributive operation. You take each term of the first polynomial and multiply it by each term of the second polynomial. Then, you add all the resulting terms together to get the final polynomial.
For example, let's say you want to multiply the polynomials (x + 2) and (x - 3).
First, you multiply the x term in the first polynomial by the x term in the second polynomial:
(x) * (x) = x²
Next, you multiply the x term in the first polynomial by the -3 term in the second polynomial:
(x) * (-3) = -3x
Then, you multiply the 2 term in the first polynomial by the x term in the second polynomial:
(2) * (x) = 2x
Finally, you multiply the 2 term in the first polynomial by the -3 term in the second polynomial:
(2) * (-3) = -6
Now, you add up all the resulting terms to get the final polynomial:
x² - x - 6
Therefore, the product of (x + 2) and (x - 3) is x² - x - 6.

DETAILS , LARPCALCL the equation of the circle in standard forn 9x^(2)+9y^(2)+36x-72y+11=0
(x + 2)2 + (y - 4)2 - 11 = 0
The equation of the circle in standard form is x2 + y2 + 36x - 72y + 11 = 0. To arrive at this answer, you need to complete the square for both the x and y terms in the equation. First, divide the equation by 9 to get the following:
x2 + y2 + 4x - 8y + 1 = 0
To complete the square for the x terms, add and subtract (4/2)2 = 16/4 = 4 to the equation:
x2 + 4 + y2 + 4x - 8y + 1 - 4 = -4
Simplifying gives you:
(x + 2)2 + y2 - 8y + 5 = 0
To complete the square for the y terms, add and subtract (8/2)2 = 64/4 = 16 to the equation:
(x + 2)2 + (y - 4)2 + 5 - 16 = -11
Simplifying gives you:
(x + 2)2 + (y - 4)2 - 11 = 0
This is the equation in standard form.

Answer:
The measure which changes the most is the mean and the new value is 84°
The correct answer option is option B
Step-by-step explanation:
How to calculate mean and median?
Given data set:
58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57
Median = (100 + 105) / 2
= 205/2
= 102.5°
Mean = (58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57) / 12
= 965 /12
= 80.4°
Range = Highest value - lowest value
= 105 - 57
= 48°
Interquartile range = Third quartile - First quatile
= 88.5° - 74°
= 14.5°
If 58° is changed to 101°
101, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57
Median = (100 + 105) / 2

Mean = (101 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57) / 12
= 1008 /12

Range = Highest value - lowest value
= 105 - 57
= 48°
First quartile = (71 + 77) / 2
= 148/2
= 74°
Third quartile = (95 + 82)/2
= 177/2

An equation is an algebraic claim that asserts the equivalency of two formulae in algebra. In the calculation 3x + 5 = 14, for example, the equivalence sign separates the numbers 3x + 5 and 14. To explain the relationship among the two words on each surface of a letter, a formula can really be employed. The software and the logo are usually interchangeable. For instance, 2x - 4 equals 2.
Set T = 300 in the equation and solve for t to discover the number of minutes it takes for the oven's temperature to reach 300°F:
T = 400 - It
300 = 400 - It / subtraction T = 300
It = 400 - 300
It = 100
t = 100 / I
T = 400 minus It I = (400 minus T) / t
When we substitute T = 0 and T = 1, we get:
I = (400 - 0) / 1\sI = 400
Now we can substitute I = 400 into the equation we found before for t:
t = 100 / I\st = 100 / 400\st = 0.25

The probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards is 11/26 or approximately 0.423.
Step-by-step explanation:
Part A
No, selecting a face card and selecting a spade when randomly selecting one card from a standard deck of cards are not mutually exclusive events. This is because there are face cards that are also spades, so there is an overlap between the two events.
Part B
The probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards can be calculated as follows
P(face card or spade) = P(face card) + P(spade) - P(face card and spade)
Part C
The probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards can be calculated as follows
P(face card or spade) = P(face card) + P(spade) - P(face card and spade)
P(face card or spade) = 12/52 + 13/52 - 3/52
P(face card or spade) = 22/52
P(face card or spade) = 11/26
Hence, the probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards is 11/26 or approximately 0.423.

Answer:
Add to eliminate X
Step-by-step explanation:
To eliminate a variable, we need to make its coefficient equal and opposite in the two equations. In this case, we can see that the coefficient of x in both equations is the same (6x), so we can eliminate x by adding the two equations.
When we add the two equations, the x term will cancel out, leaving us with the equation:
9y = 36
We can then solve for y by dividing both sides by 9:
y = 4
Now that we know the value of y, we can substitute it back into one of the original equations to solve for x. Let's use the first equation:
6x + 5y = 12
6x + 5(4) = 12
6x + 20 = 12
6x = -8
x = -4/3
Therefore, the solution to the system of equations is x = -4/3, y = 4.

Step-by-step explanation:
We can use the identity [tex]cos^3(t) = cos(t)*cos^2(t) and sin^3(t) = sin(t)*sin^2(t)[/tex] to rewrite the given parametric equations in terms of x and y:
[tex]x = 2cos(t)*cos^2(t) = 2x^2 - 2y^2[/tex]
[tex]y = 2sin(t)*sin^2(t) = 2xy^2[/tex]
Solving for y in terms of x, we get:
[tex]y = x^{3/2} / 2x^{3/4}[/tex]
Therefore, the cartesian equation of the curve is:
[tex]y = x^{3/2} / 2^{3/4}[/tex]

What is a stem and leaf plot?A stem-and-leaf plot is a table that is similar to a histogram. A stem-and-leaf plot divides a number into a stem and a leaf.
The stem is the first number in the digit. In this question, the stem is the tens value. While the leaf is the last number. In this question, it is the units digit. For example in the number 20, 2 would be the stem and 0 would be the leaf. All the numbers that have the same stem would occupy the same row.
An advantage of a stem and leaf plot is that it is easy to create while a disadvantage is that it can be tedious when the dataset is large.

Find the distance, c, between (3, –4) and (–7, 1) on the coordinate plane. Round to the nearest tenth if necessary.
Answer:
c ≈ 11.2
Step-by-step explanation:
Using the distance formula, we have:
c = √[(x2 - x1)² + (y2 - y1)²]
c = √[(-7 - 3)² + (1 - (-4))²]
c = √[(-10)² + 5²]
c = √(100 + 25)
c = √125
c ≈ 11.2
Therefore, the distance between the two points is approximately 11.2 units.
[tex]\sqrt{(-7-3)^{2} + (1-(-4))^{2} } = \sqrt{(-10)^{2} + (5)^{2} } = \sqrt{100 + 25} \\[/tex]
[tex]= \sqrt{125} = 5\sqrt{5} =11.2[/tex]
