This is a question on Present Value of Annuity and we seek the periodic withdrawal.
where:
FVA = Future value of annuity
PMT = Periodic Withdrawal
i = interest/discount rate
n = no of years
m = no of compundings per interest period
PMT = $22.01
Density=mass/volume.
1) we have to calculate the iron volume in liters.
iron volume=second level - first level=49.10 ml-45.50 ml=3.6 ml
3.6 ml=3.6 ml(1 liter / 1000 ml)=0.0036 liters
2) we calculate the mass iron in kg.
28.5 g=28.5 g(1 kg /1000 g)=0.0285 kg.
2) we calculate the density of iron.
density=0.0285 kg / 0.0036 liters=7.92 kg/L
7.92 kg/l=7.92 kg/L(1000 g/1Kg)(1000 cm³/1 L)=7.92 g/cm³.
answer: From this information the Iron density is 7.92 Kg/L or 7.92 g/cm³.
You cannot work this out without the angles
Answer:
what are the options? I would say something like 50-60
