Answer:
58.75 degreeF
Step-by-step explanation:
The initial temperature of the Soda = 40degreeF
The temperature outside is steady at 99 degreeF
The temperature of the soda became 50 degreeF after 8 minutes
In 8 minutes, the Soda gained
(50 - 40)degreeF
= 10 degreeF
If the soda gains 10 degreeF in 8 minutes, in 1 minute, it will gain 10/8degreeF
Therefore in 7 minutes, the soda will gain (10/8)*7
= 70/8
= 8.75 degreeF
The expected temperature of soda after an additional 7 minutes = 50 + 8.75
= 58.75degreeF
Answer:
7
Step-by-step explanation:
Set up an equation where x is the number
2x = 14
Divide by 2 on each side
x = 7
So, the number is 7.
Answer:
T maximum=T average -7.8 seconds
T minimum=T average +7.8 seconds
Step-by-step explanation:
Calculation for the equation that can be
use to find the maximum and minimum times for the track team
Using this equation to find the maximum times for the track team
T maximum=T average -7.8 seconds
T maximum=64.6 seconds-7.8 seconds
Using this equation to find the minimum times for the the track team
T minimum=T average +7.8 seconds
T minimum=64.6 seconds +7.8 seconds
Therefore the equation for the maximum and minimum times for the track team are :
T maximum=T average -7.8 seconds
T minimum=T average +7.8 seconds
