When a shape is rotated about its centre, if it comes to rest in a position and looks exactly like the original, then it has rotational<span> symmetry. </span>rotational<span> symmetry</span>order). This means that a regular hexagon has 6 sides, 6 lines of symmetry and anorder<span> of </span>rotational<span> symmetry of 6.</span>
Well 13 /3 = 4.3333, that sure the cost for one book and the rate. so if he bought 12 books at the same rate, then its 12*4.33333. which equals 52 dollars

Answer:
![A' = (-2,18)](https://tex.z-dn.net/?f=A%27%20%3D%20%28-2%2C18%29)
Step-by-step explanation:
Given
![A = (-1,9)](https://tex.z-dn.net/?f=A%20%3D%20%28-1%2C9%29)
![k = 2](https://tex.z-dn.net/?f=k%20%3D%202)
Required
The image
Let the point be called A, such that the image is A'.
A' is calculated as:
![A' = k * A](https://tex.z-dn.net/?f=A%27%20%3D%20k%20%2A%20A)
This gives:
![A' = 2 * (-1,9)](https://tex.z-dn.net/?f=A%27%20%3D%202%20%2A%20%28-1%2C9%29)
![A' = (-2,18)](https://tex.z-dn.net/?f=A%27%20%3D%20%28-2%2C18%29)
Answer:
1/2 gallon=2 quarts plus 3 quarts so 5 quarts then 11/4 would be 11 quarts so 11+2+3=16 quarts
Step-by-step explanation:
If the 11/4 part is confusing you on how many quarts it actually is it simply means that for every 4 quarts you get a gallon and you have 11 quarts so you can also look at it as 2 3/4 gallons if that somehow clarifies it.
