Step-by-step explanation:
Key in the expression is "s" that represents students going to the trip
The first part shows what the adventure park is going to charge, a group day charge of $300 and $30 more for the students taking the ropes course
300+30*s
The second being the amount the class can get, $500 the have in the account and $25 per student in tickets they have to sell
500+25s
The result of this subtraction is the money they need to raise to complete
C: The expression shows how much money the freshman class may need to raise in order to afford the event
Step-by-step explanation:
Intersecting secant angles theorem: The angle between two secants is half the difference of the intersected arcs.
52 = ½ (x − 38)
x = 142
Arc angles add up to 360.
360 = 80 + 38 + z + x
z = 100
Tangent-chord theorem: The angle between a tangent and a chord is half the intercepted arc angle.
y = x/2
y = 71
