Answer 1

Answer:

temperature at midnight is -39 and at 4 pm temperature will be -7

Answer 2

Step-by-step explanation:

temp. at noon - 9°c

decreasing rate - 4°/hr

temp. after some hrs - 7 below 0 = (-7°C)

difference between 9° and -7°

= 9-(-7)

= 9+7

= 16°

the temp. fell down by 16 degrees

time needed for temp to fall 16 degrees- 16÷4

= 4 hrs

4 hrs after 12 noon - 4 pm

no. of hrs from noon till midnight- 12 hrs

decreasing rate of temp - 4 degree/hr

temp fall at midnight (after 12 hrs) - 12*4 = 48degree

= 9 - 48

= -39°C
