4. Find the volume of the following hemisphere.

(Give your answer correct to 3 decimal places.)

The figures with a 180° rotation symmetry is B C and E.

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

Some figures are given in the question.

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.

Step-by-step explanation:

Answer:

m∠G = 58°

m∠J = 122°

Step-by-step explanation:

m∠G:

Straight line is 180°, so 32° + 90° + m∠G = 180°

m∠G  = 180° - 32° - 90°

m∠G  = 58°

m∠J:

vertical angles are equal to each other

m∠J = 32° + 90°

m∠J = 122°

Answer:

a. EQUATION : 180 - (90+32) =

b. Angle G = 58*

c. equation : 180 - 58* =

d. Angle J = 122*

13, 15, 27   and    13, 27, 15

you could rearrange the order but they would still be the same two triangles in different rotated positions:

15, 13, 27    is the same as 13, 27, 15, just rotated

15, 27, 13    is the same as 13, 15, 27, just rotated

27, 13, 15    is the same as 13, 15, 27, just rotated

27, 15, 13    is the same as 13, 27, 15, just rotated

Answer:

B or 2y² + 18x

Step-by-step explanation:

4y² + 6x - 2y² + 12x

combine like terms together:

4y² + (-2y²) = 2y²

6x + 12x = 18x

2y² + 18x = B

Answer:

1. 3,168 in³

2. [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

1. The total volume of the tank - as calculated by the formula for a rectangular prism - [tex]V=LWH[/tex], where L is length, W is width, and H is height. 15 · 24 · 11 = 3,960 in³. Next, we divide 3,960 by five to get 792. If 792 in³ is the air at the top, we can then subtract that from 3,960 and get 3,168. So there are 3,168 in³ of water in the tank.

2. If we dump 3,168 in³ of water into a 12,672 in³ tank, then [tex]\frac{3,168}{12,672}[/tex] of the tank will be full. Simplified, that is [tex]\frac{1}{4}[/tex]. So that means [tex]\frac{3}{4}[/tex] of the tank will be empty.

Answer:

25 boxes

Step-by-step explanation:

1)  Volume of each box = edge * edge * edge

                                        = 2.5 * 2.5 * 2.5

                                        = 15.625 cubic feet

Find the volume of the cargo hold and the volume of one box.

When you load one box, the space of the cargo hold will reduce. So when you add more boxes, the space of cargo hold will reduce continuously. So continuous subtraction is divsion.

To find the number of boxes, divide the volume of cargo hold by the volume of each box.

Number of boxes = Volume of cargo hold÷ volume of one box

                             [tex]= \frac{length *width * height}{edge * edge*edge}\\\\= \frac{15*7.5*7.5}{2.5*2.5*2.5}\\\\= 54[/tex]

Answer:

5/6 or 50 minutes

Step-by-step explanation:

Ok so first thing you want to do is find the rates of both the girls and add them up:

Amanda can finish 1 room in 2 hours

hence,

1/2   ( rooms/hours)

And we know Monica can paint the same room in 3 hours:

1/3

Now add them together such that the equation is \:

1/2+1/3=1/x .      x being the total hours they can finish the room together.

Once you add those you should get 5/6!!!

Answer:

base is 2.72 and height is 8 so you just multiply those together and i believe the correct answer is 21.7. mark me brainliest thank you!!
