What is a cross section?

Back

A cross section is a two-dimensional shape that is obtained by cutting through a three-dimensional object.

Front

If a model is cut vertically, what does the resulting cross section represent?

Back

The resulting cross section represents the shape and dimensions of the object at the point of the cut.

Front

What does a scale drawing represent?

Back

A scale drawing is a representation of an object where the dimensions are proportionally reduced or enlarged according to a specific scale.

Front

If 1 inch on a scale drawing equals 5 feet in reality, how do you find the actual dimensions?

Back

Multiply the dimensions in inches by the scale factor (5 feet) to find the actual dimensions.

Front

What is an inequality?

Back

An inequality is a mathematical statement that shows the relationship between two expressions that are not equal, using symbols like >, <, ≥, or ≤.

Front

How do you solve an inequality?

Back

To solve an inequality, isolate the variable on one side of the inequality sign using inverse operations, similar to solving an equation.

Front

What does the graph of an inequality represent?

Back

The graph of an inequality represents all the possible solutions to that inequality on a number line or coordinate plane.

Front

What is the significance of the dotted line in a graph of an inequality?

Back

A dotted line indicates that the points on the line are not included in the solution set (for < or > inequalities).

Front

What does it mean if a number line shows an open circle?

Back

An open circle on a number line indicates that the endpoint is not included in the solution set of the inequality.

Front

What does it mean if a number line shows a closed circle?

Back

A closed circle on a number line indicates that the endpoint is included in the solution set of the inequality.
