Answer:
20:5 - If you're going to simplify it, do 20/5 which is 4/1.
Step-by-step explanation:
To solve this, create an equation that follows 45% of a value is 18. This would look like x*.45=18. Now, solve for x, x*.45=18, divide by .45, x=18/.45=40, making your value 40. To check, plug in your value to the equation 40*.45=18 and see if it stays true.
The order of rotational symmetry of a kite is 1
The answer is 42,84,126 and so on.(you keep on adding 42)
