Xy (less than or equal to sign) 4
First you have to figure that it sounds confusing but. What you have to do is that 171 is 189 LESS than from one place to another. So just do : 189-171= 18. And then you know 18.
Each ticket costs $19.50
You are trying to buy 125
Multiply both together
125 x 19.50 = 2437.50
$2437.50 is the total cost
hope this helps
We can treat each distance distance traveled by the four wheelers are vectors. Their sum must be zero since the last four wheeler truck ends up where the first four wheeler truck started
d1∠1 + d2∠2 + d3∠3 + d4∠4 + d5∠5 = 0
d5∠5 = - (d1∠1 + d2∠2 + d3∠3 + d4∠4)
Since we don't know the speed of the fifth wheeler, we just add the angles and equate it to 360
20 + 30 + 0 + -40 + ∠5 = 360
∠5 = 350 or -10
The fifth wheeler must travel at an angle of -10 degrees.
