We have to find out which of the given figures have 180 degree rotation symmetry.

What do you mean by rotational symmetry ?

Rotational symmetry is defined as the property a shape has when it looks the same after some no. of rotations.

As per the question ;

We have to check which of given figures have rotational symmetry.

We know that ;

For a shape to have a rotational symmetry, the following must be true ;

If we check according to the above conditions ;

Figures (A) and (D) don't meet the conditions.

However, the above conditions are true for figures (B), (C) and (E).

This is because a rectangle , a square and a regular hexagon has equal & parallel opposite sides; and also even number of sides.

Thus , the figures having 180 degree rotation symmetry are figure B , figure C and figure E.

Answer: 45.

Step-by-step explanation: I'm not the greatest at math but I do believe that is the answer.

Answer:

The answer to your problem is, D. Yes, because 2 + 3 = 5.

Step-by-step explanation:

Refer to the converse of the pythagorean theorem. We need to have both sides equal to each other to have a right triangle.

So we need to have:

\(a^{2} + b^{2} = c^{2}\)

We would need to fill out the problem and replace A, B, and C. Which leads to either being B or D

The longest side is the hypotenuse and the value of c.

Thus the answer to our problem is, D. Yes, because 2 + 3 = 5

Answer:

By power of a point, AC⋅CB=DC⋅CE. That is, 12⋅12=6⋅(2R–6).

Then, R=15.

Answer:

A is 36 small cubes, because by looking at the image, you can see 3 rows of cubes containing 6 cubes each. So that would be 3 times 6, which is 18. There are 2 of these arrangements, one on top and the other on the bottom. So we multiply 18 by 2 to get 36 small cubes.

B is 1/64ft cubed, because the volume of a cube is length x width x height, and because each is the same (it is a cube) we take the length of the cube (1/8) and multiply it 2 times, to get 1/8 x 1/8 x 1/8 = 1/64 cubic feet.

C is 9/16 cubic feet for the volume of the entire cube. Because we know that there are 36 small cubes total, and we know that each cube is 1/64 cubic foot in volume, we multiply 36 small cubes, by their volume, 1/64 feet cubed to get the fraction of 9/16 .

Step-by-step explanation:

Answer:

3/4 x 6/4 x 2/4

Step-by-step explanation:

You need to multiply length * width * height to find volume.

Since each cube is 1/4, we have to multiply 3 for the width.

3 x 1/4 = 3/4.

Since there are 6 cubes for the length, you have to multiply 6 x 1/4 = 6/4

Finally, since the height is 2 cubes, you have to do 2 x 1/4 = 2/4

Finally, you multiply them all.

3/4 x 6/4 x 2/4

Answer:

  17 numbers with any number of digits

  12 numbers using as many digits as possible

Step-by-step explanation:

It depends on how many digits you are required to use. If you're not required to use more than one digit, then the possible numbers are ...

  0, 2, 8, 20, 28, 80, 82, 88,

  208, 280, 288, 802, 808, 820, 828, 880, 882

for a total of 17 numbers.

__

If you must use the maximum possible number of digits, then the 1-digit numbers and the 2-digit numbers containing 0 must be taken off the list, leaving ...

  028, 082, 088, (and all the above 3-digit numbers)

for a total of 12 numbers.

Hope i helped :)

Answer:

558,404

Step-by-step explanation:

Answer:

452.4 square feet

Finding the diameter:

Since there are 3 centimeters for every 4 feet, we need to divide 18 by 3

18 ÷ 3 = 6 which means the ratio is scaled up by 6 so we multiply 4 by 6

4 · 6 = 24 that means that the diameter of the base of the fountain is 24 feet

Finding the area:

Since the area of a circle is πr² we need to divide the diameter by 2 to get the radius(r)

24 ÷ 2 = 12 now we need to square 12 (which is multiplying it to itself ex. 5² is 5 · 5)

12 · 12 = 144 now we multiply it by π

π · 144 ≈ 452.38934 lastly we round it

452.4 square feet

Answer:

512 1/2 inch cubes

Step-by-step explanation:

-In order to get 4 inches width, you will need 8 1/2 cubes (1/2 x 8 = 4)

-In order to get 4 inches height, you will need 8 1/2 cubes (1/2 x 8 = 4)

-In order to get 4 inches length, you will need 8 1/2 cubes (1/2 x 8 = 4)

8 length x 8 width x 8 height = 512 1/2 inch cubes to build a solid 4x4x4 inch cube.

Answer:

512 1/2 cubes

Step-by-step explanation:

The volume of the cube model : 4 x 4 x 4 = 64 cubic inches

1/2 x 1/2 x 1/2 = 1/8 - one 1/2 inch cube

64 / 1/8 = 512 1/2 inch cubes

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

Hope you understood the answer and I hope it helps you :)

Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

Step-by-step explanation:

The difference beteen 9.2 ounces and 8.1 ounces is  1.1 ounces

   and the difference in price is   .49

       so 1.1 ounces cost .49

           $ .49 / 1.1 oz = $  .445  per ounce

Then Reid's bowl should cost   7.8 oz  * $ .445 / oz = $3.47

By proportion that is:(54/150) * 8450= 54 * 56 1/3= 3042

Answer: The correct answer is:

Probability of rolling a number less than 3: 2/6 or 1/3

Step-by-step explanation:

Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.

Probability of not rolling a number less than 3: 4/6 or 2/3.

Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D
