We have been given that Federica used 13.4 gallons of gasoline to drive 448.9 miles and we have to find out average number of miles she drove per gallon of gasoline.
In order to find out average number of miles Federica drove per gallon of gasoline we will divide total number of miles she drove by the total number of gallons of gasoline she used in driving total number of miles.
After simplifying our expression we will get
Therefore, the average number of miles that Federica drove per gallon of gasoline is 33.5 miles per gallon.

The three points A,B,C are all points on this circle.
Each point is then equal distance from the center, that distance being the radius of the circle.
Using the distance formula, we can find the center of the circle (x,y):
Plugging in points A and B into distance formula, then setting them equal to each other gives:
Right away we can cancel out the x terms leaving:
Expand Left side and Solve for y:
Plug in points B and C as before:
Here we can cancel the y-terms.
Expand and solve for x:
Therefore the center of the circle is the point (6,3)
