What is a coordinate in a Cartesian plane?

Back

A coordinate is a pair of numbers (x, y) that define a point's position on a Cartesian plane, where 'x' represents the horizontal position and 'y' represents the vertical position.

How do you determine the new location of an object after descending and ascending from a depth?

Back

To find the new location, subtract the descent from the initial depth and then add the ascent. For example, if an object is at -430 feet, descends 90 feet, and ascends 300 feet, the calculation is: -430 - 90 + 300 = -220 feet.

What is the unit rate?

Back

The unit rate is a comparison of two different quantities when they are combined together. It expresses how much of one quantity corresponds to one unit of another quantity.

Front

How do you calculate the unit rate of soccer balls kicked per minute?

Back

To find the unit rate, divide the total number of soccer balls kicked by the total time in minutes. For example, if Sarah kicks 48 soccer balls in 6 minutes, the unit rate is 48 ÷ 6 = 8 soccer balls per minute.

Front

What does it mean when a temperature is below zero degrees Celsius?

Back

A temperature below zero degrees Celsius indicates that it is below the freezing point of water, meaning it is cold enough for water to freeze.

Front

How do you calculate the temperature change from one day to the next?

Back

To calculate the temperature change, subtract the new temperature from the previous temperature. For example, if the temperature on Sunday is -15°C and it decreases by 12 degrees, the new temperature is -15 - 12 = -27°C.

Front

What is the significance of negative numbers in real-world contexts?

Back

Negative numbers are used to represent values below a defined point, such as temperatures below freezing, depths below sea level, or financial losses.

Front

How do you convert a fraction to a unit rate?

Back

To convert a fraction to a unit rate, divide the numerator by the denominator to find the value per one unit of the denominator.

Front

What is the formula for finding the new depth after descending and ascending?

Back

The formula is: New Depth = Initial Depth - Descent + Ascent.

Front

What is the relationship between distance and time in calculating rates?

Back

The relationship is expressed as Rate = Distance ÷ Time, which shows how much distance is covered in a specific amount of time.
