Answer 1

Answer:

15 (C) as the current temperature is -12 +7 = -5°C

16 (D) similarly -12 - 2 = -14°C

17 (D) -4 + 4 = 0°C -3 = -3°C + 6 = 3°C

Answer 2

Answer:

15. C. -5 degree Celsius

16. D. -14 degree Celsius

17. D. 3 degree Celsius

Step-by-step explanation:

According to the given picture, each marking has a difference of 2 degree celsius. Therefore, the recorded temperature is -12 degree Celsius.

15. If temperature increases by 7 degree centigrade, then the resulting temperature will be: -12 + 7 = -5 degree Celsius

16. If temperature decreases by 2 degree centigrade, then the resulting temperature will be: -12-2 = -14 degree Celsius

17. If the recorded temperature is -4 degree Celsius and then it increases by 4 degree centigrade, then the temperature becomes 0 degree Celsius (-4+4). Now, if the temperature again falls by 3 degree centigrade, the resulting temperature becomes -3 degree Celsius. Again, the temperature is said to increase by 6 degree centigrade. Hence, the final temperature will be: -3+6= 3 degree Celsius
