Suppose a standard six-sided die is rolled and you receive $0.50 for every dot showing on the top of the die. What should the cost of playing the game be in order to make it a fair game? The cost of playing the game should be $. ?

the last choice

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
