Answer 6)
Given:
Room temperature at present = 40°C
Rate = 5° per hour
Decrease in temperature in 10 hours = 50°C
Room temperature after 10 hours = 40°C – 50°C = -10°C
Thus, the room temperature after 10 hours, after the process begins, is -10°C.
Answer 7)
a) 4 correct =5,5,5,5
6 incorrect =-2,-2,-2,-2,-2,-2,-2
His total score is 5+5+5+5+(-2)+(-2)+(-2)+(-2)+(-2)+(-2)
=5+5+5+5. & =(-2)+(-2)+(-2)+(-2)+(-2)+(-2)
=20. & =-12
=8
b) 5 correct =5,5,5,5,5
5 incorrect =-2,-2,-2,-2,-2
5+5+5+5+5+(-2)+(-2)+(-2)+(-2)+(-2)
=5+5+5+5+5. & = (-2)+(-2)+(-2)+(-2)+(-2)
=25. & =-10
