100
If asked to round a decimal to the nearest thousandth, this place value determines the result.
What is the ten-thousandths place?
100
This is a set of all points equidistant from a given point.
What is a circle?
100
Every right triangle has two of these.
What are legs?
100
This is what we call two expressions separated by an equal sign. We solve this.
What is an equation
100
These two operations require common denominators when dealing with fractions.
What are addition and subtraction?
200
When dividing a number by a decimal between 0 and 1, the quotient is this relative to the dividend. (< , >, or =)
What is >?
200
An irrational number found from dividing a circle’s circumference by its diameter.
What is pi?
200
In a right triangle, this is the side opposite the right angle.
What is the hypotenuse?
200
We call the process of multiplying a number by itself this.
What is squaring a number?
200
An algebraic expression is called this when all like terms have been combined.
What is simplified?
300
If you want to convert a fraction to a decimal, you use this operation.
What is division?
300
The distance between a circle’s center and any of its point is called this.
What is the radius?
300
This is the relationship described by Pythagoras’ theorem.
What is a2+b2=c2
300
When we reverse the process of squaring a number, we find this of a number.
What is the square root?
300
Two numbers are this of each other if their product is 1.
What is reciprocal?
400
This type of real number never repeats nor terminates.
What is an irrational number?
400
This characteristic of a circle is the distance around its outside; it is represented by the equation: this = pi * diameter.
What is the circumference?
400
To find the area of a triangle, we use this formula.
What is (1/2)*base*height?
400
If a true statement (i.e. 0 = 0) is reached after solving an equation, this phrase describes the solution.
What is "all real numbers?"
400
This is the value that makes an equation true.
What is the solution?
500
When moving a number’s decimal point to the right, you are multiplying by a power of this.
What is ten?
500
This characteristic is the number of square units it takes to cover a circle; it is represented by the equation: this = pi * radius2.
What is the area of a circle?
500
We use the fact that a triangle is half of this shape to derive the area formula.
What is a rectangle?
500
When writing out a square root, this is the number under the radical sign.
What is the radicand?
500
If a contradiction (i.e. 5 = 0.3) is reached when solving an equation, this phrase is used to describe the solution.
What is "no solution?"
