Answer:
choice f
Step-by-step explanation:
take ∆ abc
ab^2 = ac^2 + ab^2
400 = 225 + ab^2
ab =√ 175
∆aDB
bd = 20-x
ad^2 = 175 -(20-x)^2
∆acd
225 = x^2 + 175 - 400+ 40x - x^2
225 = -225 + 40x
450 = 40x
x = 45/4
The equation which can determine v, the number of visits Ariana must make to earn a free movie ticket is given by :76=25+8.5v
v=6
What is the total number of points required for a free movie ticket?
The total number of points that Ariana needs to watch a free movie is 76 points, which can be earned by the sum of signing up points plus the number of visits(v) multiplied by the points per visit, 8.5 points
76=25+8.5v
We can make v the subject of the formula
76=25+8.5v
76-25=8.5v
51=8.5v
v=51/8.5
v=6
