(43 cards)

What does the combination < mean?

Front

less than

Back

What is a right triangle?

Front

A triangle containing a 90° angle.

Back

What is the denominator and where is it located?

Front

the bottom number of the fraction. Example: 5 is the denominator for 3/5

Back

What is a quadrilateral?

Front

4 sided polygon

Back

What does circumference mean?

Front

the perimeter of a circle

Back

Define prime number. Give two examples.

Front

A prime number is a whole number that can be divided evenly by itself and by 1 but not by any other number. Only has two factors. Examples: 2 (factors are 1 and 2), 5 (factors are 1 and 5)

Back

What is a perfect square? Give examples.

Front

Perfect squares are numbers that have exact square roots. Example: the square root of 25 is 5

Back

What does the combination >_ mean?

Front

greater than or equal to

Back

What is the Pythagorean Theorem?

Front

Only for right triangles: a^2 + b^2 = c^2

Back

What is a equilateral triangle?

Front

3 equal sides

Back

How many degrees is an obtuse angle?

Front

more than 90 but less than 180

Back

What is the formula to find the are of a rectangle?

Front

A = l(w)

Back

What does diameter mean?

Front

The measurement from one side of a circle to another.

Back

Define factors. Give two examples.

Front

Factors are integers (whole numbers) that can be divided evenly into another integer. Example: 8 can be divided by 2 and 4, so 2 and 4 are factors of 8

Back

Define composite number. Give two examples.

Front

A whole number that can be divided evenly by itself and 1. Has more than two factors. Example: 6 (factors of 6 are 1, 2, 3, and 6), 9 (factors of 9 are 1 and 2)

Back

Define factorial. Give an example.

Front

Represented by an exclamation point (!). You calculate it by finding the product of a whole number and all the whole numbers less than it down to 1. Example: So 6 factorial (6!) is 6x5x4x3x2x1 = 720

Back

What is the formula used to find the area of circle?

Front

Area = π(R^2)

Back

How many degrees is a straight line?

Front

180 degrees

Back

Define base. Give an example.

Front

The number used as a factor at least two times. (number raised to an exponent) Example: 4^3 has a base of 4. 5^10 has a base of 5

Back

What is a complementary angle?

Front

two angles that add up to 90 degrees

Back

Whats the formula to find the volume in a cylinder?

Front

V = π (R^2) H

Back

What is the numerator and where is it located?

Front

the top number of the fraction. Example 3 is the numerator for 3/5

Back

How many degrees in a quadrilateral?

Front

360 degrees

Back

How do you find the area of a triangle?

Front

A=1/2bh

Back

What does the combination =/ mean?

Front

does not equal

Back

What is the formula for circumference?

Front

C=2πR or C=π(d)

Back

How many degrees is an acute angle?

Front

more than 0 but less than 90

Back

How many degrees is a right angle?

Front

90 degrees

Back

What is a cube root? Give an example.

Front

A factor of a number when multiplied by itself 3 times produces the original number. Example: cube root of 27 is 3. 3x3x3 = 27

Back

What is a fourth root? Give an example.

Front

Same as cube root but instead of 3 its not 4. Example: fourth root of 81 is 3. 3x3x3x3 = 81

Back

What is the formula to find the perimeter of a rectangle?

Front

P = 2l + 2w

Back

What is a common denominator?

Front

A common denominator is two or more fractions with the same denominator.

Back

What is a isosceles triangle?

Front

when two sides have equal length.

Back

What is a supplementary angle?

Front

two angles that add up to 180 degrees

Back

what does the combination <_ mean?

Front

less than or equal to

Back

Whats the formula to find the volume in a box?

Front

V = L x W x H

Back

What happens when two fractions don't have the same bottom number?

Front

When fractions don't have the same common denominator, you have to find one. There are two methods .1) divide the larger denominator by the smaller denominator. 2)multiply the denominator of the first fraction by the denominator of the second fraction.

Back

How many degrees in a circle?

Front

360 degrees

Back

Define reciprocal. Give an example

Front

The number by which another number can be multiplied to produce 1. Example: reciprocal of 3 is 1/3. if you multiply 3 times 1/3 you get 1.

Back

Define integers. Give two examples.

Front

Any positive or negative whole numbers. Example: -3, 0, 1, -4, 10

Back

What is an irrational number? Give examples.

Front

Numbers that don't have whole numbers as square roots. Example: square root of 30 is 5.4772255 with no end.

Back

What does radius mean?

Front

The measurement from the center of a circle to any point on the edge.

Back

What does the combination > mean?

Front

greater than
