Answer: Vector Resolution
Step-by-step explanation:
Vector components can form right triangle, since one acts vertically and the other acts horizontally. Thus, the original vector forms the hypotenuse of the right triangle formed by its components.
The process of breaking a vector down into its components is called vector resolution.
So... let's change the concentration percentage to decimal format. .. so 40% is just 4/100 or 0.4 and so on.

so... whatever "x" and "y" may be, we know the must add up to 6 liters.
and whatever 0.4x and 0.8y are, we also know, they must add up to a 3 of concentrated amount.
thus

solve for "x", to see how much of the 40% solution will be needed.
what about "y"? well, y = 6 - x.
Answer:
$4500
Step-by-step explanation:
Given data
State income tax= $234
we are told that the tax paid is 5.2% of her income
Let her earnings be x
so
5.2% of x = $234
5.2/100*x=234
0.052x= 234
x= 234/0.052
x= $4500
Hence her earnings is $4500
The correct answer is B. Multiply input number by 4
