9)1= one 1/9 for each
so do that 5 more times and u get 6/9 for each friend
or 2/3
Well, you will need to find out how much each person reads per hour. To find that out, you will need to divide 126 by 3, resulting in 41 pages an hour. If you do the same thing with Zack, you will be able to find out that he reads 45 pages an hour. Now, you will need to multiply the number of pages per hour by 5! if you multiply 41 by 5, you get 205 pages. If you multiply 45 by 5, you get 225 pages. Pam isnt able to read more than 215 pages in 5 hours, but Zack is able to.
Answer:
The refrigerator was at around 13 ∘C
Step-by-step explanation:
Newton's Law of Cooling:
The rate of change of a body temperature (amount of heat loss/time of loss) is directly proportional to the difference between its own temperature and the surroundings.
T ⇒ temperature
t ⇒ time
Tenv ⇒refrigerator temperature
⇒ rate of change of he temperature
-h ⇒ constant of proportionality (negative because the temperature is decreasing inside the refrigerator)
We have 3 points:
time (minutes) - Temperature (∘ C)
0 (when the pan was put in the refrigerator) - 46
15 (after 15 minutes) - 27
30 (15 minutes after the first 15 minutes) - 19
= -h (27 - Tenv)
= -h (19 - Tenv)
Now we have a system of two equations and two variables
The refrigerator was at around 13 ∘C
