Ray uses 1/4 of a gallon of gasoline to drive a distance of 5 1/2 miles. at this rate, how many miles can he drive on 1 gallon of gas?

ray can drive miles on 1 gallon of gas.

Ray can drive 22 miles on 1 gallon of gas.

Step-by-step explanation:

Ray uses of a gallon of gasoline to drive a distance of miles.

Ray drive a distance of 5.5 miles by using 0.25 gallon of gasoline.

Now we can solve this question by unitary method.

∵ Ray can drive on 0.25 gallon of gas = 5.5 miles

∴ Ray can drive on 1 gallon of gas =

                                                        = 22 miles

Ray can drive 22 miles on 1 gallon of gas.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
