26.95 rounded to the nearest whole is 27, because .95 is bigger than .5. I hope this helps you.
Answer:
It really depends on what type of equation you are solving.
However, if you're working with an equation that contains variables, it's advised that you should get rid of the variables first before the whole numbers/integers.
Step-by-step explanation:
This question is the application of differential eqns in order to derive a model for the temperature dependence with time. Actually, a general equation has already been derived for this type of cases. This equation is known as the Newton's Law of Cooling. The equation is
(T - Ts) / (To -Ts) = e^(-kt)
where T is the the temperature at any time t
Ts is the surrounding temperature
To is the initial temperature
k is the constant
t is the time
several assumptions have been made to arrive at this form, i suggest you trace the derivation of the general formula.
First we need to look for k using the initial conditions that is @t = 1.5 min, T = 50 F
substituting we get a k = 0.2703
therefore @ t = 1 min, T = 55.79 F
@ T = 15 F the time required is 9.193 min.
