Suppose 29 cars start at a car race. in how many ways can the top 3 cars finish the race?

any of the 34 cars can finish first  

any of the remaining 33 cars can finish second

any of the remaining 32 cars can finish third  

Thus, the top 3 finishes can be done in (34)(33)(32) = 35904 ways

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
