60 cm^3 of gasoline are mixed with 55 cm^3 of water. What is the average density of the mixture? answers in meters
i did (.6*680)+(.55*1000)
then divided by 95...is this workable?

if i have a question with a picture then how can i post it?

You should have divided by 1.15. That will give you the answer in kg/m^3
Actually, you are mixing up volumes in liters and densities in kg/m^3, but as long as the denominator volume is in liters (as are the numerator volumes), you will get the right answer in kg/m^3.

A uniform ladder which is 10m long and weighs 300N, leans with its upper end against a smooth vertical wall and its lower end on rough horizontal ground. A man weighing 700N stands on the ladder at point of 6m above the ground. Calculate the magnitutes and the directions of the forces exerted on the ladder by: (a) the wall (b) the ground
