A PARALLEL line will have the EXACT SAME SLOPE

SLope = rise / run =   (2-8) / (0-8) = -6 / -8 = 3/4 

Perhaps they sold only  200 tickets?

d = day tix

200-d = night tix

d (800) + (200-d)550 = 153900

800d + 110000 - d550 =153900

d250 = 43900

d= 175.6     you can't sell a PARTIAL ticket so....

                     Alan is correct......even with this assumption of 200 tix, the numbers still don't work

= 5a - b/12

To find the ANGLE from the airplane to the second radio station:

tan x  =  136/115  (opposite/adjacent)     

x=  49.78 degrees    FROM DUE WEST    180 - 49.78 = 130 .22 degrees is the COMPASS BEARING from the plane

Two ways to find the DISTANCE  :  1: Pythagorean Theorem

or   Sin 49.78 = opposite/hypotenuse = 136/hypotenuse      

  136/ (sin 49.78) = hypotenuse      (the DISTANCE)  = 178.11 miles

We'll have to make an assumption that they finish the test at a constant rate.

then   3 in 30  means  10 in 100  (10 minutes for each student)

100 minutes

Usually by reducing them ...like example: sqt 8  = sqrt(4*2) = 2 sqrt2    or sqrt128 = sqrt(64*2) = 8sqrt2   etc

1030

30.53 sq units

1/8 = HV
