## 100 terms · The following words need to be mastered before entering advanced mathematics content for the 2012-2013 school year.

### Percent of Increase

the percent of change when the new amount is greater than the original, percent by which an amount has been raised compared to the original amount

### Composite Number

A whole number with more than two factors. In other words, a number that is not prime. Zero and one are neither prime nor composite

### Volume of Triangle Pyramid

V=1/3 Bh, where is the area of the triangular base and is the height of the pyramid

### Volume of a Figure

measured in cubic units, it is the number of cubes required to fill it completely

### 5 Area & Length Conversions

1 acre = (1/640) miles2

1 mile = 1760 yards = 5280 feet

1 yard = 3 feet = 36 inches

1 foot = 12 inches

1 inch = 2.54 centimeters

### 7 Volume Conversions

1 cup = 8 fluid ounces = (1/2) pint = (1/4) quart = (1/16) gallon

1 mile = 63360 inches = 5280 feet = 1760 yards

1 yard = 36 inches = 3 feet = (1/1760) mile

1 foot = 12 inches = (1/3) yard = (1/5280) mile

1 pint = 16 fluid ounces = (1/2) quart = (1/8) gallon

1 inch = 2.54 centimeters = (1/12) foot = (1/36) yard

1 liter = 1000 centimeters = 1 decimeters = (1/1000) meters

### 5 Properties of Addition

Additive Identity a + 0 = a

Additive Inverse a + (-a) = 0

Associative of Addition (a + b) + c = a + (b + c)

Commutative of Addition a + b = b + a

Definition of Subtraction a - b = a + (-b)

### 5 Properties of Multiplication

Multiplicative Identity a * 1 = a

Multiplicative Inverse a * (1/a) = 1

Associative of Multiplication (a ** b) ** c = a ** (b ** c)

Commutative of Multiplication a ** b = b ** a

Distributive Law a(b + c) = ab + ac

### reciprocal

The inverse of a fraction; when multiplied by the original fraction, it results in a product that equals one

### vertex

The point of intersection for two sides of a plane figure, three sides of a solid figure, or the endpoints of two rays that form an angle.

### polygon

Three or more line segments in a plane that forms a closed figure. The line segments never cross but meet at their endpoints.

### diameter

A line segment that passes through the center of a circle and has its endpoints on the circle

### mean

The sum of a group of numbers divided by the number of numbers; also known as the average

### median

A value found by ordering a group of data from least to greatest and choosing the middle value of the group.

### scale drawing

A drawing of an object that is different in size (usually smaller than the original) but keeps the same proportions

### radius

A length that is half the diameter of a circle; the distance from the center of the circle to the circle itself

### lowest terms

A fraction with all common factors (other than 1) factored out of the numerator and denominator

### prism

a solid figure that has two congruent, parallel polygons as its bases. Its sides are parallelograms.

### x-coordinate

The value on the x-axis used to locate a point on the coordinate graph. It is the first value in an ordered pair.

### y-coordinate

The value on the y-axis used to locate a point on the coordinate graph. It is the second value in an ordered pair.

### ordered pair

Two numbers listed in a specific order; it describes a point on the coordinate graph

### outlier

data that are more than 1.5 times the value of the interquartile range beyond either quartile

### inequality

an open sentence that uses greater than, less than, and equal to, to compare two quantities
