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 represent a situation where a quantity must not exceed a maximum value using an inequality?

Back

You can represent it by setting up an inequality where the variable plus any existing quantity is less than or equal to the maximum value.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (r) that relates two proportional quantities, often expressed in the equation c = rg.

Front

How do you find the constant of proportionality from a given relationship?

Back

You can find it by dividing the total cost (c) by the number of gallons (g) to get r, or by rearranging the equation c = rg.

Front

What is the formula for volume of a rectangular prism?

Back

The volume V of a rectangular prism is calculated using the formula V = length × width × height.

Front

How do you calculate the volume of a box?

Back

To calculate the volume of a box, multiply its length, width, and height together.

Front

What does it mean for a box to be '70% full'?

Back

It means that the volume of the contents inside the box is 70% of the total volume of the box.

Front

How do you determine how many smaller boxes fit into a larger box?

Back

You can determine this by dividing the volume of the larger box by the volume of the smaller box.

Front

What is the process to increase the dimensions of a box?

Back

To increase the dimensions of a box, you add a certain amount to each dimension (length, width, height) to find the new dimensions.

Front

What is the significance of the maximum capacity in a real-world scenario?

Back

The maximum capacity indicates the limit to how much can be contained or held, which is crucial for planning and resource management.
