SY23-24 Unit 1 Final Exam Review (Standard and ACC)

Front

What is the scale of a map?

Back

A scale of a map is a ratio that represents the relationship between a distance on the map and the actual distance on the ground. For example, a scale of 1 inch = 20 miles means that 1 inch on the map corresponds to 20 miles in reality.

Front

How do you calculate the distance between two points on a map using the scale?

Back

To calculate the distance between two points on a map, measure the distance in inches on the map and then multiply that measurement by the scale factor. For example, if two points are 4.5 inches apart and the scale is 1 inch = 20 miles, the actual distance is 4.5 * 20 = 90 miles.

Front

What is a zero pair in mathematics?

Back

A zero pair is a pair of numbers that add up to zero. For example, if you have +4 and -4, they form a zero pair because 4 + (-4) = 0.

Front

What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. For example, the absolute value of -7 is 7, and the absolute value of 9 is 9.

Front

How do you find the distance between two numbers on a number line?

Back

To find the distance between two numbers on a number line, subtract the smaller number from the larger number and take the absolute value of the result. For example, the distance between -7 and 9 is |9 - (-7)| = |9 + 7| = 16.

Front

What is the formula for calculating total earnings from hourly work?

Back

Total earnings can be calculated using the formula: Total Earnings = Hourly Rate x Number of Hours Worked. For example, if you earn $4.25 per dog and walk 10 dogs, your total earnings are 4.25 * 10 = $42.50.

Front

What does it mean to add integers?

Back

Adding integers involves combining positive and negative whole numbers. If both integers are positive, you add them normally. If one is negative, you subtract the absolute value of the negative integer from the positive integer.

Front

What is the result of adding a negative number to a positive number?

Back

When you add a negative number to a positive number, you subtract the absolute value of the negative number from the positive number. For example, -10 + 10 = 0.

Front

What is multiplication in terms of repeated addition?

Back

Multiplication can be thought of as repeated addition. For example, 4 x 3 means adding 4 three times: 4 + 4 + 4 = 12.

Front

How do you calculate the total cost of multiple items?

Back

To calculate the total cost of multiple items, multiply the price of one item by the number of items purchased. For example, if one dog costs $4.25 and you walk 10 dogs, the total cost is 4.25 * 10 = $42.50.
