Answer:
It will take 8 minutes for the temperature to reach 76°
Step-by-step explanation:
The expression for the total temperature in degrees at time t can be written as;
T=I+EM
where;
T=total temperature
I=initial temperature
E=temperature increase per minute
M=number of minutes
This can also be written as;
total temperature=initial temperature+temperature increase per minute×number of minutes
In our case;
T=76°
I=40°
E=4.5°
M=m
replacing;
76=40+(4.5×m)
4.5 m=76-40=36
(4.5 m)/4.5=36/4.5
m=8
It will take 8 minutes for the temperature to reach 76°
Answer:
The answer would be B
Step-by-step explanation:
The reason that we know this is because the line is falling and because it is a solid line then we know that it is ≥ and not just >. the solid line already gets rid of C and D. A is a positive number which would cause the line to go the opposite direction. Therefore B is your only answer left.
