1st year= 18000 x 0.85 = 15300
2nd year= 15300 x 0.85 = 13005
3rd year= 13005 x 0.85= 11054.25
The value of the length DF is 1/4 of that of CD because of the Angle Bisector Theorem for triangles.
<h3>
What is the Angle Bisector Theorem?</h3>
The Angel Bisector Theorem states that if a ray bisects an angle of a triangle, it dissects the side of the triangle that is opposite to the dissected angle into parts that are proportionate to the adjacent sides.
Note that the angle that has been dissected here is ∠CBD. Thus,
=

➷ The formula for circumference is
1)
Divide both sides by
d = 9.99 (consider this to be 10)
Half this to find the radius
10/2 = 5
It would be figure B.
2)
Divide both sides by :
d = 11.99 (consider this to be 12)
Divide by 2 to find the radius:
12/2 = 6
It would be figure C.
3) area =
r^2 = 48.97515909
r = 6.998 (consider this to be 7)
It would be figure D
4)
r^2 = 35.98174
r = 5.998 (consider this to be 6)
It would be figure C.
5) radius = diameter / 2
radius = 3
It would be option C

Answer: 30 $15 tickets and 20 $35 tickets
Step-by-step explanation:
.X%2BY=50
2.15X%2B35Y=1150
From eq. 1,
15X%2B15Y=750
Subtract from eq. 2,
15X%2B35Y-15X-15Y=1150-750
20Y=400
Y=20
Then,
X%2B20=50
X=30
30 $15 tickets and 20 $35 ticket
