A volleyball league invited 84 teams to compete in
a tournament. After each round
half of the teams were
eliminated. Which equation
represents the number of
teams, t, that remained in the
tournament after r rounds?

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
