Which geometric figure has 120 rotational symmetry?
A. rhombus
B. regular pentagon
C. square
D. equilateral triangle
Answer:
D
Step-by-step explanation:
An equilateral triangle, and all regular polygons with 3n sides, thus D.
A figure that has 120 rotational symmetry will look exactly the same after the figure is rotated by 120 degrees. An equilateral triangle has 120 rotational symmetry.
When a rhombus, a regular pentagon or a square is rotated by 120 degrees, the resulting shapes do not have the same layout as the initial shape.
However, an equilateral triangle will look the same when rotated by 120 degrees.
I've added an attachment that illustrates the rotation by 120 degrees of an equilateral triangle.
From the attached figures, you can see that points ABC on figure 1 and are changed on figure 2 ; however, both triangles maintain the same layout.
Hence, an equilateral triangle has 120 degrees rotational symmetry

Answer:
6.2 cm
Step-by-step explanation:
Apply the Law of cosines, given as:
c² = a² + b² - 2ab×Cos(C)
Where,
a = 4 cm
b = 8 cm
c = AB = ??
C = 50°
Plug in the value into the equation
c² = 4² + 8² - 2*4*8*Cos(50)
c² = 16 + 64 - 64*Cos(50)
c² = 80 - 64*Cos(50)
c² = 38.861593
c = √38.861593
c = 6.2 cm (nearest tenth)

So there teams and you had to put the highest value and the lowest ones the numbers are 20 -25 -10 25 -15 how would you put them in order
Answer:
25, 20, -10, -15, - 25
Step-by-step explanation:
first you start with the positive so since its going from Highest to Lowest the positive would always come first, So you would start with 25 since its your highest number and then get to 20. Now the negatives are the same just with the Negative (-) sign, so just do it like how you would with the positive numbers by counting up so first would be -10 and then your next one.
Hope this helps

Step-by-step explanation:
Step 1: Define
5(w + 2.2) - 4w = 9.3
Step 2: Solve for w
Distribute 5: 5w + 11 - 4w = 9.3Combine like terms: w + 11 = 9.3Isolate w: w = -1.7Step 3: Check
Plug in w into the original equation to verify it's a solution.
Substitute in w: 5(-1.7 + 2.2) - 4(-1.7) = 9.3(Parenthesis) Add: 5(0.5) - 4(-1.7) = 9.3Multiplication: 2.5 + 6.8 = 9.3Addition: 9.3 = 9.3Here we see that 9.3 does indeed equal 9.3.
∴ w = -1.7 is the solution to the equation.

Which of the following ratios are equivalent to 60%?
Check all that apply.
D A. 15:25
D B. 4:6
C. 3:5
D. 10:20
OE. 12:36
Answer:
its A and C
Step-by-step explanation:
The ratios that are equivalent to 60% are 15:25 and 3:5.
The correct options are A and c.
What is ratio?A ratio is a numerical relationship showing how often one value includes or is included inside another. It is used to compare two numbers.
To determine which ratios are equivalent to 60%, we can first convert 60% to a fraction or decimal.
To convert 60% to a fraction, we can write it as 60/100 and simplify by dividing both the numerator and denominator by their greatest common factor, which is 20.
This gives us 3/5.
To convert 60% to a decimal, we can divide 60 by 100, which gives us 0.6.
Now, we can check which ratios are equivalent to 60% by simplifying them and seeing if they result in 3/5 or 0.6.
A. 15:25 can be simplified by dividing both the numerator and denominator by 5, giving us 3:5, which is equivalent to 60%.
B. 4:6 can be simplified by dividing both the numerator and denominator by 2, giving us 2:3. To check if this ratio is equivalent to 60%, we can convert it to a fraction by writing it as 2/3. To see if this is equivalent to 3/5, we can cross-multiply and simplify:
2/3 = x/100
Multiplying both sides by 100:
200/3 = x
Approximating 200/3 to the nearest whole number gives us 67. Therefore, the ratio 4:6 is not equivalent to 60%.
C. 3:5 is already in the form of a ratio equivalent to 60%.
D. 10:20 can be simplified by dividing both the numerator and denominator by 10, giving us 1:2. To check if this ratio is equivalent to 60%, we can convert it to a fraction by writing it as 1/2. This is not equivalent to 3/5, so 10:20 is not equivalent to 60%.
E. 12:36 can be simplified by dividing both the numerator and denominator by 12, giving us 1:3. To check if this ratio is equivalent to 60%, we can convert it to a fraction by writing it as 1/3. This is not equivalent to 3/5, so 12:36 is not equivalent to 60%.
Therefore, the ratios that are equivalent to 60% are A and C.

Find each quotient write the answer in simplest form 2 3/4 Divided by 1 7/8
Answer: 22/15, or 1 7/15
Step-by-step explanation:
1. Convert each mixed number into an improper fraction
2 3/4 -> 11/4
1 7/8 -> 15/8
2. Divide fractions using the keep, change, flip method
Keep the first fraction: 11/4
Change the division sign to a multiplication sign
Flip the second fraction: 15/8 -> 8/15
3. Evaluate by multiplying the numerators and denominators together, respectively
11/4 x 8/15
88/60
4. Simplify
88/60 -> 44/30 -> 22/15
The quotient is 1 7/15
What is division of fraction?The division of fractions means dividing a fraction into further equal parts.
For example, If you have three-fourth, and you divided each into 2 parts you would get a total of six, but this would represent six-eighths of the total.
Given are two mixed fractions, 2 3/4 and 1 7/8, we need to divide them,
Convert each mixed number into an improper fraction :-
2 3/4 = 11/4
1 7/8 = 15/8
Divide fractions :-
The second fraction we be reciprocated, and both will get multiplied,
11 / 4 x 8 / 15
Evaluate by multiplying the numerators and denominators together, respectively
88/60 = 22 / 15
= 1 7/15
Hence, the quotient is 1 7/15

als den is 12 feet longer than it is wide. if the dens area is 405 square feet, what are the dimensions of the room?
Answer:
The room has a length of 27 feet and width 15 feet.
Step-by-step explanation:
Given that:
Area of den = A = 405 square feet
Let,
L represent the length of room and W represent the width of room.
L = W+12
Area = Length * Width
[tex]405=(W+12)*W\\405=W^2+12W\\W^2+12W-405=0[/tex]
Factorizing the equation
[tex]W^2-15W+27W-405=0\\W(W-15)+27(W-15)=0\\(W-15)(W+27)=0\\[/tex]
Either,
W-15 = 0
W=15
Or,
W+27=0
W=-27
As the width cannot be negative, therefore,
Width of den = 15 feet
Length of den = 15+12 = 27 feet
Hence,
The room has a length of 27 feet and width 15 feet.

Answer:
Step-by-step explanation:
Area of shape A = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]
= [tex]\frac{1}{2}(4)(5)[/tex]
= 10 square units
Area of shape B = Length × width
= 4×2
= 8 square units
Area of shape C = 5 square units
Area scale factor = [tex](\frac{\text{Area of image}}{\text{Area of original}} )[/tex]
Area scale factor = (Scale factor)²
If scale factor = 2
Area scale factor = 2² = 4
Rule for the dilation,
Area of image = Area scale factor × Area of preimage
Therefore, area of figure A after dilation = 4×10 = 40 square feet
Area of figure B after dilation = 4×8 = 32 square feet
Area of figure C after dilation = 4×5 = 20 square feet
Similarly, we can get areas by different scale factors given in the table.
