Answer:
The constant of proportionality is 1/4.
Step-by-step explanation:
That would be 40 divided by 5. So the price for one student ticket was $8.
Answer:
20 ........................
Answer:
From the given figure we can see that :---
MN||PO, MN=PO and MP=NO
Therefore, angle M=angle N (adjacent sides of the trapezoid)

angle M=angle N= (6×18)+20=108+20 =128°
angle O =(180°-128°)=52°
<h3>Hence, angle O is <u>52°.</u></h3>
