If 50% of 2:3 solution of milk and water is replaced with water, then the concentration of the solution is reduced by?

Step-by-step explanation:

Let the quantity of milk and water be 40 and 60 respectively.

After removing 50% of solution,

Quantity of milk = 20 and quantity of water = 30

Therefore, the concentration of the solution is reduced from 40 to 20. Hence the solution is reduced by 50%.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
