You are totally correct, except for the representation of the formula. If h is 2 times the radius, then h = 2r, and the formula would be . But your answer is correct. Good job!
5x = # of games won 2x = # of games lost The total number of win and lose is 147. 5x + 2x = 147 Solve for x, 5x +2x=147 7x = 147 x=21 The ratio of games won: #of games lost is 5:2 5x21=105: 2x21=42 105 wins: 42 lost
