borishaifa [10]

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.

A pharmacist has 40% and 80% iodine solutions on hand .How many liters of each iodine solutions will be required to produce 6 li
svetoff [14.1K]
So... let's change the concentration percentage to decimal format. .. so 40% is just 4/100 or 0.4  and so on.

\bf \begin{array}{lccclll}
&amount&concentration&
\begin{array}{llll}
concentration\\
amount
\end{array}\\
&-----&-------&-------\\
\textit{40\% sol'n}&x&0.4&0.4x\\
\textit{80\% sol'n}&y&0.8&0.8y\\
-----&-----&-------&-------\\
mixture&6&0.5&3
\end{array}

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    \bf \begin{cases}
x+y=6\implies \boxed{y}=6-x\\
0.4x+0.8y=3\\
----------\\
0.4x+0.8\left( \boxed{6-x} \right)=3
\end{cases}

solve for "x", to see how much of the 40% solution will be needed.

what about "y"?  well, y = 6 - x.

castortr0y [4]

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
