Answer:
The day's high temperature written as degrees Celsius is 25 degrees' Celsius.
Step-by-step explanation:
The day's high temperature in St. Louis ,Missouri was recorded as 77 degrees F.
We are supposed to find the day's high temperature written as degrees Celsius.

So,

C=25
Thus, The day's high temperature written as degrees Celsius is 25 degrees' Celsius.
It is 16,000. because 0 is lower than 5
P(t)=number of sheet of paper after t minutes.
p(t) will have to be equal to 0, wnen the printer use all 100 sheets of paper;
Therefore;
if p(t)=0
Then:
-8t+100=0
We solve this equation.
-8t+100=0
8t=100
t=100/8
t=12.5
Answer: the printer prints 100 sheets of paper in 12.5 minutes.
