Answer:
A
Step-by-step explanation:
6/3 = 2
Answer: 44%
Step-by-step explanation:
There are other ways of doing this but here's how I did it:
Starting with an arbitrary price for the shirt of $100, I took 30% off and arrived at $70.
Then 20% off $70 is $56 (20% is one-fifth, so divide 70 by 5 and you get 14. Subtract 14 from 70 and you get 56.
Now subtract 56 from 100 and you get 44, so to get to 56 from 100 you subtract 44%.
You could also use a calculator or google it but that would be missing the point of studying math and benefiting from its practical applications, e.g., how to figure things out for yourself. And that wouldn't be much fun, would it?
Use the Circumference Formula of a Circle: C=2(pi)(r). The radius is the length from the center to a point on the circle. The circumference is essentially the perimeter of the circle, so the “edge” around the circle is the circumference.
