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 ;
The shape must have an even number of sides i.e., 4 , 6 , etc.The shape must have equal and parallel opposite sides.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.

A sequence can be generated by using an = 4a(n - 1), where a1 = 6 and n is a whole
number greater than 1. What are the first four terms in the sequence?
A: 6, 24, 96, 384
B: 6, 10, 14, 18
C: 6, 20, 100, 500
D: 6, 20, 76 300
Answer:
First four terms are: 6 , 24 , 96 , 384
Step-by-step explanation:
a₁ = 6
an = 4a(n-1)
a₂ = 4* a₍₂₋₁₎ = 4 * a₁ = 4*6 = 24
a₃ = 4*a₍₃₋₁₎ = 4 * a₂ = 4 * 24 = 96
a₄ = 4* a₍₄₋₁₎ = 4 * a₃ = 4 * 96 = 384

You randomly choose one of the four marbles. Without replacing the first marble, you choose a second marble. there are 1 blue, 1 green, 1 yellow, and 1 red. Use tree diagram
Answer:
12 total possible outcomes
Step-by-step explanation:
To do this, we can use the Fundamental Counting principle, which is :
An event M has m possible outcomes. An event N has n possible outcomes. The total number of outcomes of event N followed by event N is m x n.
When you first pick up a marble (event M), there are 4 possible outcomes (yellow, red, green, blue). Since you do not replace the marble, when you pick the second time (event N) there are only 3 other possible colors.
As we know, m x n = to total possible outcomes.
So, 4 x 3 = 12 total possible outcomes.

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:
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*
