A figure in the flag has rotational symmetry if the figure can be mapped onto itself by a rotation between 0° and 360° about the center of the figure.
What is symmetry?Symmetry in everyday language refers to a sense of harmonious and beautiful proportion and balance. In mathematics, "symmetry" has a more precise definition, and is usually used to refer to an object that is invariant under some transformations; including translation, reflection, rotation or scaling. Something is symmetrical when it is the same on both sides. A shape has symmetry if a central dividing line (a mirror line) can be drawn on it.To learn more about symmetry refer to:

Step-by-step explanation:
You would do 24 × 13/12
This would be 26
Answer:
26
Step-by-step explanation:
First, we convert the question into an equation.
12/13x = 24.
We multiply both sides by 13 to get rid of the fraction that is on the left side of the equation.
12x=312.
Dividing both sides by 12, we get:
x = 26

Answer: 4 1/6
Step-by-step explanation:
Find the value of x .
Answer:
Step-by-step explanation:
Set up a proportion
BE/BC = BD/BA
BE = 3
BC = 2 + 3 = 5
BD = x + 2
BA = x + x + 2
BA = 2x + 2
3/5 = (x + 2) / (2x + 2) Cross multiply
3(2x + 2) = 5 (x + 2) Remove the brackets
6x + 6 = 5x + 10 Subtract 6 from both sides
6x = 5x + 4 Subtract 5x from both sides
x = 4

The area of a rectangle is 16 1/3 square inches.The width is 4 2/3. Inches.Find the length
Answer:
Let the length of the rectangle be L. Then we can use the formula for the area of a rectangle:
Area = Length x Width
Substituting the given values, we get:
16 1/3 = L x 4 2/3
To solve for L, we can first convert the mixed numbers to improper fractions:
16 1/3 = 49/3
4 2/3 = 14/3
Substituting these values, we get:
49/3 = L x 14/3
To solve for L, we can multiply both sides by the reciprocal of 14/3:
49/3 ÷ 14/3 = L
Simplifying, we get:
L = 49/3 x 3/14
L = 7/1
L = 7
Therefore, the length of the rectangle is 7 inches.

Susan’s apartment is shown below. Assuming that all rooms are rectangular, find the areas described below. All measurements are in feet
Please help me solve this equations. I am working on rational and irrational numbers this week. The equation is attached
A)
The area of a square is equal to the square of the length of its side. Since the side of the square is x, then the area is equal to x^2. Since the area must be equal to 400 square inches, then:
\(x^2=400\)B)
To solve this equation, take the square root to both members of the equation:
\(\Rightarrow\sqrt[]{x^2}=\sqrt[]{400}\)The square root of the square of a variable is always equal to the absolute value of that variable. The square root of 400 is 20. Then:
\(\Rightarrow|x|=20\)This equation has two solutions:
\(\begin{gathered} x_1=20 \\ x_2=-20 \end{gathered}\)C)
Since x represents a distance, the negative solution does not make sense in the context of the problem.
D)
Since a square has four sides of equal lengths, and one side has a length of 20 inches, then four times 20 inches is the length needed to go around the painting. Since 4*20=80, then, the length of the wood trim needed to go around the painting, is:

A right rectangular prison is shown with some measurements given in units. The length of the diagonal from point A to point B is 13 units. What is the height, h, of the prison in units?
The required value of h, representing the height of the three-dimensional rectangle, is 12.
The diagonal of a three-dimensional rectangle is defined by the equation d² = x² + y² + h². To solve for h, we can rearrange the equation as follows:
h² = d² - x² - y²
Given the values d = 13, x = 3, and y = 4, we can substitute them into the equation:
h² = 13² - 3² - 4²
h² = 169 - 9 - 16
h² = 144
Taking the square root of both sides, we find:
h = 12
Therefore, the value of h, representing the height of the three-dimensional rectangle, is 12.

An interior designer is redecorating a room that is 26 feet long by 18 feet wide by 9 feet high. At one end of the room is a door that is 6 feet 6 inches high and 4 feet wide. One of the walls contains 2 windows, each of which is 2 feet wide by 2 feet 6 inches high.
A: How much will it cost to carpet the floor if the carpet sells for $18.00 a square yard? $
B: How much will it cost to wallpaper all four walls if wallpaper costs $0.75 per square foot? $
C: How much will it cost to paint the ceiling using paint that sells for $25 per gallon if a quart of paint will cover 88 square feet? $
D: What will be the cost of the entire project? $
Answer: A: It will cost $936.00 to carpet the floor.
B: It will cost $297.00 to wallpaper all four walls.
C: It will cost $33.25 to paint the ceiling.
D: The cost of the entire project will be $1266.25.
Step-by-step explanation:
To calculate the costs for carpeting, wallpapering, painting, and the overall cost of the project, we need to determine the areas that need to be covered and the corresponding prices for each material.
Given dimensions:
Room length: 26 feet
Room width: 18 feet
Room height: 9 feet
Door dimensions:
Height: 6 feet 6 inches
Width: 4 feet
Window dimensions (each):
Width: 2 feet
Height: 2 feet 6 inches
A: Carpeting the floor:
To find the area of the floor, we multiply the length and width of the room:
Floor area = Length × Width = 26 feet × 18 feet = 468 square feet.
To convert to square yards (since the carpet is sold per square yard), we divide by 9:
Floor area in square yards = 468 square feet / 9 = 52 square yards.
Cost to carpet the floor = Floor area in square yards × Cost per square yard = 52 square yards × $18.00 = $936.00.
B: Wallpapering the walls:
To find the area of the walls, we calculate the perimeter of the room (2 × (Length + Width)) and multiply it by the height of the room:
Wall area = Perimeter × Height = 2 × (26 feet + 18 feet) × 9 feet = 396 square feet.
Cost to wallpaper the walls = Wall area × Cost per square foot = 396 square feet × $0.75 = $297.00.
C: Painting the ceiling:
To find the area of the ceiling, we multiply the length and width of the room:
Ceiling area = Length × Width = 26 feet × 18 feet = 468 square feet.
Since a quart of paint covers 88 square feet, we need to determine the number of quarts required:
Number of quarts = Ceiling area / Coverage per quart = 468 square feet / 88 square feet = 5.32 quarts.
Since a gallon contains 4 quarts, the number of gallons required is 5.32 quarts / 4 quarts = 1.33 gallons.
Cost to paint the ceiling = Number of gallons × Cost per gallon = 1.33 gallons × $25.00 = $33.25.
D: Cost of the entire project:
Total cost = Cost to carpet the floor + Cost to wallpaper the walls + Cost to paint the ceiling
= $936.00 + $297.00 + $33.25 = $1266.25.
Therefore:
A: It will cost $936.00 to carpet the floor.
B: It will cost $297.00 to wallpaper all four walls.
C: It will cost $33.25 to paint the ceiling.
D: The cost of the entire project will be $1266.25.

I didn't want to overthink it like I normally do with everything else in life so i was like, there are 3 boxes on the side and 4 boxes on the bottom, so 3 times 4= 12.
Now i know that the area of the neighborhood is 12 blocks and 20 blocks equals a mile. 12 is obviously not 20, twelve is actually a little bit over half of twenty or .50%, so the best answer would be D.60%.

show that both are commutative
Based on the information, both ∧ (conjunction) and ∨ (disjunction) satisfy the commutative property.
How to explain the commutative property.It should be noted that to prove the commutativity of the logical connectives ∧ (conjunction) and ∨ (disjunction), we need to show that they satisfy the commutative property
From the truth table, both P ∧ Q and Q ∧ P have the same truth values for all combinations of truth values of P and Q. Therefore, we can conclude that P ∧ Q ≡ Q ∧ P, and ∧ (conjunction) is commutative.
In order to prove P ∨ Q ≡ Q ∨ P, we construct a truth table for both expressions. Both P ∨ Q and Q ∨ P have the same truth values for all combinations of truth values of P and Q. Therefore, we can conclude that P ∨ Q ≡ Q ∨ P, and ∨ (disjunction) is commutative.
Hence, both ∧ (conjunction) and ∨ (disjunction) satisfy the commutative property.
