3. describes the accuracy of a measured or estimated value compared to an actual amount. It is always a positive percent.
7. a percent used to calculate interest on the principal
8. the distance around the circle
10. the amount of increase from the cost of an item to its selling price
11. the long side of a right triangle that is opposite the right angle.
12. the initial amount
14. The y- coordinate of the point where the line crosses the y-axis.
17. a number that produces a specific number when multiplied by itself.
18. an enlarged or reduced drawing of an object that is proportional to the actual object.
19. a segment that passes through the center of a circle and has both endpoints on the circle.
20. the ratio of a length in the image to the corresponding length in the original figure.
22. an equation that relates proportional quantities. We can compare the part to the whole written in the same format as a constant of proportionality: y=mx

1. rise/run
2. interest that is applied to the initial amount only
3. a rule in geometry that states that the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other sides.
4. The formula used is y = mx + b
5. the markup as a percent increase from the original cost
6. in math, a statement that shows that two expressions are equal.
9. the amount of decrease from the cost of an item to its selling price
13. the markdown as a percent decrease from the original cost
15. is a segment that has one endpoint at the center and the other endpoint on the circle.
16. describes how much a quantity has changed relative to its original amount. It can be an increase or decrease.
21. either of the two sides that form the right angle in a right triangle.
