IM Math 7 Unit 5 Lesson 2 Practice

Front

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

Back

When you add a positive temperature to a negative temperature, you find the difference between the two absolute values and determine the sign based on which temperature is larger.

Front

If the temperature is -2°C and it rises by 15°C, what is the new temperature?

Back

The new temperature is 13°C.

Front

What number is less than -0.1°C but greater than -0.8°C?

Back

The number is -0.7°C.

Front

What is a number that is less than 7°C?

Back

The number is 6°C.

Front

How do you calculate the rise in temperature from -6°C to 9°C?

Back

Subtract the initial temperature from the final temperature: 9°C - (-6°C) = 15°C.

Front

If Noah made 125% of 64 cookies, how many cookies did he make?

Back

Noah made 80 cookies (125% of 64 is 80).

Front

If 90% of Noah's cookies were sold, how many cookies were left?

Back

Noah had 8 cookies left after the bake sale.

Front

What is the formula to calculate percentage increase?

Back

Percentage Increase = ((New Value - Original Value) / Original Value) * 100.

Front

What does it mean to find a number that makes a statement true?

Back

It means to identify a value that satisfies the given inequality or equation.

Front

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

Back

Negative temperatures indicate temperatures below freezing, which can affect weather, climate, and physical states of matter.
