The number of cards left is 600-280=320.
So the 320 cards left are what percent? we count it like this:

=53.3..%
so the answer is 53.3%
C = 2pi(r). Find the radius of the circle first. Then multiply that by 2pi.
Pi=3.14159... 2pi = 2 x 3.14159...
Therefore C = 2 x 3.14159... x r
Answer:
-4
Step-by-step explanation:
Do (y1-y2)/(x1-x2) so (3-(-5))/(0-2)
8/-2=-4
D -3m-4n+14. Once you write out the equation, you have to combine all the like terms, also known as simplifiying
