Which of the following is a rational number: -1/5, pi, 0.333..., 5/9?

Back

-1/5, 0.333..., and 5/9 are rational numbers. Pi is not a rational number.

Front

What are the coordinates of a point in the Cartesian plane?

Back

Coordinates are expressed as (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What does it mean for a number to be irrational?

Back

An irrational number cannot be expressed as a simple fraction; its decimal representation goes on forever without repeating.

Front

In a game where players catch a ball in their quadrant, what does the quadrant represent?

Back

Front

How do you find the missing vertex of a rectangle given three vertices?

Back

To find the missing vertex, use the properties of rectangles: opposite sides are equal and diagonals bisect each other.

Front

What is the significance of the point (-1, 9) in a game involving quadrants?

Back

The point (-1, 9) indicates the location in the Cartesian plane where the ball bounces, determining which player must catch it.

Front

What is the formula for determining if a number is rational?

Back

A number is rational if it can be expressed as a/b, where a and b are integers and b ≠ 0.

Front

What are the four quadrants of the Cartesian plane?

Back

Quadrant I: (+,+), Quadrant II: (-,+), Quadrant III: (-,-), Quadrant IV: (+,-).
