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:
x = 0
y = -2
Step-by-step explanation:
-5x + y = -2
x = 0

Answer:
Step-by-step explanation:
Total number of coolers that need to be shipped from a warehouse is 8.5
Each cooler holds 8.91 pounds of products. This means that the total weight of products in pounds, held by 8.5 coolers is 8.91 × 8.5 = 75.735 pounds
Each cooler also holds 2.54 pounds of packing peanuts for safe delivery.
This means that the total weight of packing peanuts in pounds, held by 8.5 coolers is 2.541 × 8.5 = 21.59 pounds
the total weight of the coolers to be shipped will be
75.735 + 21.59 = 97.325 pounds
