Let's use the variable x to represent the length of the first and second pieces.
If the third piece has twice the length of the first and second, its length is 2x.
If the fourth piece has half the length of the first and second, its length is 0.5*x.
Adding all four pieces and equating to 54 inches, we have:

So the length of each piece is:
12 inches, 12 inches, 24 inches and 6 inches.
Answer:
Rotational symmetry of 180 degrees around the origin - yes
Rotational symmetry of 270 degrees around the origin - no
Step-by-step explanation:
thanks to math bits notebook we can see a visual representation
As you can see the parallelogram has rotational symmetry of 180
Answer:
The surface area of the cylinder will be "131.88".
Step-by-step explanation:
The given values are:
Height of cylinder,
h = 4 m
Radius of cylinder,
r = 3 m
As we know,
The surface are of cylinder is:
⇒ 
On substituting the values, we get
⇒ 
⇒ 
⇒ 
Answer:
English translate for my help please??!
Step-by-step explanation:
We know that
To determine the intervals you will need to find the lowest and highest numbers
lowest number------> 1
highest number-----> 35
(1 and 35).
A general rule would be 5-7 intervals,
so
I will choose 5.
Here are the intervals with the number of people that were in each:
[1-7] -----------> (9)
[8-14] ---------> (14)
[15-21] --------> (8)
[22-28] ------> (3)
[29-35]-------> (5)
The total of the frequencies was 39 people, and that is how many numbers there are.
