McGraw-Hill Math Grade 5 Answer Key Chapter 9 Lesson 5 Using Celsius Temperatures
Solve
Question 1.
The high temperature for a day in July was 35°C. The low temperature that same day was 23°C less. What was the low temperature on that day?
Answer:
12°C was the low temperature on that day.
Explanation:
The high temperature for a day in July = 35°C.
The low temperature that same day = 23°C less.
Difference:
The high temperature for a day in July – The low temperature that same day
= 35°C – 23°C
= 12°C.
Question 2.
What temperature does the thermometer show?
If the temperature increased by 14°C, what would the thermometer show?
Answer:
30°C would the thermometer show.
Explanation:
The thermometer shown = 16°C.
If the temperature increased by 14°C.
=> The thermometer shown + 14°C
=> 16°C + 14°C
=> 30°C.
Question 3.
Kevin and Sharon live in different cities. One day, the temperature in Kevin’s city was 24°C. The temperature in Sharon’s city that same day was 9°C higher. What was the temperature in Sharon’s city?
Answer:
33°C was the temperature in Sharon’s city.
Explanation:
The temperature in Kevin’s city one day = 24°C.
The temperature in Sharon’s city that same day was 9°C higher.
=> The temperature in Sharon’s city that same day = The temperature in Kevin’s city one day + 9°C
=> 24°C+ 9°C
=> 33°C.
Question 4.

If the temperature decreased 25°C, what would the thermometer show?
Answer:
The thermometer shows = 9°C.
Explanation:
The thermometer showing = 34°C
If the temperature decreased 25°C.
=> The thermometer shows = The thermometer showing – the temperature decreased
=> 34°C – 25°C
=> 9°C.
