Still don't know what the heck "k" is... I have one equation and two unknowns... The formula simplifies to:
0.105 = e^(-k*t)
and I need to solve for t...
I honestly don't think this was meant to be a "trick" question... but you're right. We don't know the temperature of the pizza *before* we put it in the oven. Would this matter? I assumed (maybe wrongly) that after 20 minutes in the oven @ 450 degrees, that it would come out at that...
Homework Statement
Bob loves vegetarian pizza. How long will it take Bob's pizza to cool to 110 degrees if he bakes it at 450 degrees for 20 minutes? The temperature in his house is a balmy 70 degrees.
Homework Equations
T(t) = Ts + Do*e^(-k*t) where...
Do = initial temperature...
