which of these figures has rotational symmetry?
Answer: Choice C
We can rotate the figure 180 degrees so that it lines up with its original image perfectly. In other words, the before and after would be identical images.
The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. The correct option is C.
What is Rotational Symmetry?The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. When turned 180 degrees or with specific angles, clockwise or anticlockwise, many geometrical forms appear to be symmetrical. Examples include squares, circles, hexagons, and more.
The shape that has a rotational symmetry is option C, which is a parallelogram.
Hence, the correct option is C.

A factory inspector found flaws in 3 out of 18 wooden boxes what is the experimental probability that the next wooden box will be flawed
A factory inspector found flaws in 3 out of 18 wooden boxes. What is the experimental probability that the next wooden box will be flawed?
Write your answer as a fraction or whole number.
-------------------------------------------------------------------------------------------------------------
Remember, The experimental probability is the number of times an event occurs out of the total number of trials.
-------------------------------------------------------------------------------------------------------------
Flawed Boxes / Total
=3/18
=1/6
So The Answer is 1/6
The experimental probability that the next wooden box will be flawed is 1/6=0.167.
What is experimental probability?
The experimental probability of an event is the ratio of the number of outcomes in which a specified events occurs to the total trials.
Mathematically, Experimental probability= f/n, where f is the number of times an event occurs, n is the total number of trials.
Total number of wooden boxes= 18
Total number of boxes that are flawed= 3
Therefore, required experimental probability = 3/18
=1/6
Hence, the experimental probability that the next wooden box will be flawed= 1/6

What is a trinomial?A trinomial is an algebraic expression that has three non-zero terms and has more than one variable in the expression.
Given is a trinomial, 2x²-16x+30
On factorizing,
= 2x²-16x+30
= 2x²-10x-6x+30
= 2x(x-5)-6(x-5)
= (2x-6)(x-5)
= 2(x-6)(x-5)
Hence, the factors for the given trinomial is 2(x-6)(x-5)

Answer: The error is the number of sides, it should be 9 sides and not 25. Correct is 1 260 degrees
Step-by-step explanation:
The error is the number of sides, it should be 9 sides and not 25.
Polygon sum of interior angles formula: 180 x (n-2)
So here n = 9 (sides)
180 x (9-2)
180 x 7 = 1 260 degrees
Answer:
sum of interior angles = 180 * n - 2
n = number of sides
in this case, the shape has 9 sides so n = 9
so the correct answer should be
= 180 * (9-2)
= 180 * 7
= 1260

Judys town voted on a new speed limit. 95% of the 2,000 votes were in favor of the new speed limit. How many voted were in favor
Answer:
1,900 votes were in favor.
Step-by-step explanation:
Given that the statement indicates that 95% of the 2,000 votes were in favor, you can find the number of votes in favor by calculating the 95% of the total number of votes:
2000*95%=1900
According to this, the answer is that 1,900 votes were in favor.
why is the order you use to name polygons important when writing a congruency statement?
Answer:
When stating that two triangles are congruent, use a congruence statement. The order of the letters is very important, as corresponding parts must be written in the same order. Notice that the congruent sides also line up within the congruence statement. One congruence statement can always be written six ways.

What is the distance between the points (7, 8) and (-8, 0) on a coordinate grid?
Answer:
17 units
Step-by-step explanation:
Going from one point to the other, the change in x is 15 and that in y is 8. Therefore, applying the Pythagorean Theorem,
distance = √(225 + 64) = √289 = 17
The distance between the two points is 17 units.
Answer:
Solution :-Distance = √(x2 - x1)² + √(y2 - y1)²
Distance = √(7 - (-8))² + √(8 - 0)²
Distance = √(7 + 8)² + √(8)²
Distance = √(15)² + √(8)²
Distance = √(225 + 64)
Distance = √(289)
Distance = 17 unit

A 24-ounce can of mixed nuts contains 50% peanuts, 0.20 almonds, 1/10 cashews, and 0.20 hazelnuts. Which of the following represents the total amount of almonds and hazelnuts in the can?
Answer:
9.6 ounces
Step-by-step explanation:
Step 1
We find the amount of ounces of Almonds
Total amount of nuts in the container = 24 ounces
0.20 of the nuts are almonds.
Hence,
The amount of almonds = 0.20 × 24 ounces
= 4.8 ounces
Step 2
We find the amount of ounces of hazelnuts
Total amount of nuts in the container = 24 ounces
0.20 of the nuts are hazelnuts.
Hence,
The amount of hazelnuts = 0.20 × 24 ounces
= 4.8 ounces
Step 3
Therefore, the total amount of almonds and hazelnuts in the can is
4.8 ounces + 4.8 ounces
= 9.6 ounces
