Answer 1

Answer:

Answer will be +5 degree

Step-by-step explanation:

because at first HR = 3 degree rises per HR so -4 was there so -4 +3= -1

second hr= -1+3=2

third HR = 2+3 = 5

Answer 2

Answer:

The Temprature of fridge= -4 ( equation 1)

The electric supply cuts Temprature rises=3

Hours electricity cuts=3

In 1 hrs 3

=9

So, answer will be come from current Temprature - new temprature=9-4

= 5
