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.

In Frank's piggy bank, there are only quarters
and dimes. He has 37 coins, and has a total of
$5.50. How many quarters does he have?
Answers
Answer:
12 quarters
Step-by-step explanation:
number of quarters ---------x
number of dimes ------------y
therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1
0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2
equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12
there are 12 quarters
Write the decimal as a percent
Answers
Answer:
3/5
Step-by-step explanation:
Answer:
66%
Step-by-step explanation:
0.6 repeating is 66%.
From decimal to percent:
To get a percent from a decimal number, move the decimal over twice to the right. In this case, 0.66 would become 66% because the decimal moved to the right twice.
From decimal to fraction to percent:
I already know that 2 divided by 3 is 0.6 repeating. 2 divided by 3 could also be written as [tex]\frac{2}{3}[/tex]. So the first step is complete, from the decimal 0.6 repeating to the fraction [tex]\frac{2}{3}[/tex]. Now from [tex]\frac{2}{3}[/tex] to a percent. If you get a 2 out of 3 ([tex]\frac{2}{3}[/tex]) you would get a 66%.

Answers
Answer:
Midpoint is[tex](-25.15,10.2)[/tex]
Step-by-step explanation:
A line segment refers to line that has two endpoints.
Let [tex](a,b),(c,d)[/tex] be the endpoints of a line segment.
Midpoint of the line segment is given by [tex](\frac{a+c}{2} ,\frac{b+d}{2})[/tex]
Take the given points as follows:

Miko and her parents rent boats for the afternoon. Her parents rent a canoe and Miko rents a kayak. • It costs $20.49 to rent a canoe plus an additional $7.49 for each hour. • It costs $17.99 to rent a kayak plus an additional $5.99 for each hour. Miko and her parents rent one canoe and one kayak for the same amount of time, and their total cost for the rentals is $78.92. Write and solve an equation to determine the amount of time, in hours, that they rented the kayak and canoe.
Answers
Answer:
Kayak and Canoe rented for 3 hours
Step-by-step explanation:
Let the time for which they rent canoe & kayak = x hours
Total canoe cost = 20.49 + 7.49x , Total kayak cost = 17.99 + 5.99x
Given] Total canoe & kayak cost = 78.92
So, (20.49 + 7.49x) + (17.99 + 5.99x) = 78.92
20.49 + 17.99 + 7.49x + 5.99x = 78.92 ; 38.48 + 13.48x = 78.92
13.48x = 78.92 - 38.48 ; 13.48x = 40.44
x = 40.44 / 13.48 ; x = 3

Since its a 45-45-90 triangle then the 2 legs are going to be the same.
Answer:
90°
Step-by-step explanation:
Always remember that the sum of all angles is 180°.
So there are two 45° angles, so just add them up and you get 90
So if you subtract 90 from 180, you get 90, and that's your answer

The other legs of the right-angle triangle will be 12.23 units and 11.81 units.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The right angle triangle is shown with the angle of 44° and the length of the hypotenuse is 17 units.
Then the measure of the length of x will be given by a cosine angle of 44°.
cos 44° = x / 17
x = 12.23 units
Then the measure of the length of y will be given by a sine angle of 44°.
sin 44° = y / 17
y = 11.81 units
Thus, the other legs of the right-angle triangle will be 12.23 units and 11.81 units.
