Answer:
A
Step-by-step explanation:
Let x ml be the amount of paint color B mixed with 40 ml of paint color A.
In 40 ml of paint color A are 15% of black pigment, so there are

of black pigment.
In x ml of paint color B are 60% of black pigment, so there are

of black pigment.
In total we het x+40 ml of mixture. There are 25% of black pigment that is

Thus,

Answer:
All have same magnitude.
Step-by-step explanation:
Given that
Vector 1 = V+ (-W) = V - W
So the magnitude of vector 1, R₁

R₁ = V -W
For vector 2
Vector 2 = W - V = W - V
So the magnitude of vector 2, R₂

R₂ = V - W
For vector 3
Vector 3 = (-V) - (-W) = - V + W = W - V
So the magnitude of vector 3,

R₃ = W -V
So all have same magnitude.
