The alcohol concentration of the mixed solution is 20%
Simplification :
Based on the given condition, formulate :
35% ×0.40 + 0.6 ×10% ÷{ 0.4+0.6}
Calculate the product :
Calculate the sum or difference :
Any fraction with denominator 1 is equal to numerator : 0.2
Multiply a number to both numerator, denominator : 0.2 ×
Calculate the product or quotient :
A fraction with denominator equals to 100 to a percentage 20%.
How do you find the concentration of a mixed solution?
In general when your are mixing two different concentrations together first calculate number of moles for each solution (n=CV ,V-in liter) then add them together it will be total moles,then concentration of mixture will be = total moles / total volume(liter).

Hey there!:
The potential energy is U = m*g*h
Substitute 560.0 J for U = m*g*h so, 560.0 = m*g*h
g = 9.8 m/s²
50 ft in meters :
1 ft = 0.3048 m
50 ft = 50 * 0.3048 => 15.24 m
m = 560.0 / g*h
m = 560.0 / 9.8 * 15.24
m = 560.0 / 149.352
m = 3.74 kg
35 ft in m : 35 * 0.3048 => 10.668 m
The change initial in potencial energy from point A to B is:
mg ( h1 - h2 ) = 3.74* ( 9.8 )* (15.24 - 10.668 )
=> 36.652 * ( 15.24 - 10.688 ) =
36.652 * 4.552 => 167.57 J
According to the conservation of energy
The change in potencial energy should be equal to the change in kinetic energy , so the , the change in kinetic energy is :
ΔK = 167.57 J
