Newton's Law of cooling is
T(t)=T_{a}+(T_{0}-T_{a})e^{-0.1947t}
where
T(t) = temperature of the body after t hours, 80 °F
T_{a} =  ambient temperature, 65 °F
T_{0} = normal body temperature, assumed to be 98.6 °F

The elapsed time since death is obtained from
65+(98.6-65)e^{-0.1947t|} = 80
33.6e^{-0.1957t}=15
-0.1947t=ln \frac{15}{33.6}
t= \frac{ln(15/33.6)}{-0.1947} =4.142

4.142 hours before 2 am is 9:52 pm (the previous day) approximately.

Answer:  9:52 pm the previous day.

How is 1 and 23/100 expressed as a decimal
AleksandrR [38]
1 is expressed in decimal simply as 1.00
23/100 is expressed in decimal by 0.23

1 is a whole number and for it to become a decimal we must convert it into a fraction and perform division. 1 in fraction form is simply 1/1 which equals to 1.

23/100 to become decimal we need to divide 23 by 100. It will give us a quotient of 0.23
