Answer:
It will take 17.5 minutes to reach 50 degrees F.
Step-by-step explanation:
Current temperature = -13 degrees F
With the engine on, the temperature goes up by 3.6°F per minute.
Let us assume that it takes x minutes to reach 50 degrees F.
So, the time taken will be =
=> 
=> 
x = 17.5 minutes
The expression that tells how much the temperature needs to change from -13°F to 50°F is :
It will take 17.5 minutes to reach 50 degrees F.
Answer:

Step-by-step explanation:
cos(x)=
x=38.5(correct to the nearest tenth)
Answer: 3.37 i think
Step-by-step explanation:
It is 28.8 because if you do 48% * 60 you get 28.8 =)
Answer:
Proportionality equation: 
Linear equation: 
Step-by-step explanation:
So the amount that Cameron earns = 7/hr
Hours = x
And total earned amount = y
So we can form an equation from this for the total amount:
But the question asks us for a proportionality equation so:
Proportionality constant = k
So we get the equation:
