Aubrey is deciding between two truck rental companies. Company A charges an initial fee of $80 for the rental plus $1 per mile driven. Company B charges an initial fee of $50 for the rental plus $2 per mile driven. Let AA represent the amount Company A would charge if Aubrey drives xx miles, and let BB represent the amount Company B would charge if Aubrey drives xx miles. Write an equation for each situation, in terms of x, x, and determine the interval of miles driven, x, x, for which Company A is cheaper than Company B.

step-by-step explanation:

a = 11 : 4

b = 38

c = 1 for every 6

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
