Answer:

19gallons

Step-by-step explanation:

Given parameters:

  Mike's car rate  = 21miles per gallon

   Distance  = 400 miles

Unknown:

Number of gallons of gas = ?

Solution:

 The rate of fuel consumption by Mikes car is given as;

         Rate  = \frac{distance traveled }{number of gallons}

             Number of gallons = \frac{distance traveled }{rate}  

            Number of gallons = \frac{400}{21}   = 19gallons

The temperature in frostville was at 50*F at midnight,and it dropped at a constant rate for the next 10 hours.
bazaltina [42]

After 10 hours the temperature is shown on the graph as 30 degrees.

50 degrees - 30 degrees = 20 degrees.

The temperature dropped 20 degrees in 10 hours.

Divide the change by the time:

20 degrees / 10 hours = 2 degrees per hour.

Because the temperature dropped, the change would be negative.

The answer is D. -2 degrees per hour.
