The carson family paid $192 for two adult and three youth tickets to an amusement park. at the same park, the davis family paid $148 for one adult and four youth tickets. let x represent the cost of an adult ticket, and let y represent the cost of a youth ticket. which system of equations can be used to find ticket cost?

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

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
