Given mass=1 kg, volume=400cm³, density=?
The formula for finding density is ρ=m/v where ρ is density, m is volume and vis volume
ρ=1kg/400cm³
ρ=0.0025kg/cm³
Therefore the density of the sand is 0.0025kg/cm³
The greatest common factor of 9, 18 and 21 is 3 so that is the number that we'll factor out
to do this divide all three numbers by 3 to get
3(3a-6b+7c)
I hope I've helped!
so we know that 9 friends are going to a movie right. So what we are going to do in this problem is you are going to divide 83.25 ÷ 9. and then you will find out how much they each paid. So each person will pay 9.25.
hope that helped
