how many kilograms of pure water is to be added to 100 kilograms of a 30% saline solution to make it a 10% saline solution
Irina-Kira [14]

Answer:

  200 kg

Step-by-step explanation:

If w is the amount of water added, then the concentration of the solution is ...

  salt/solute = 100(0.30)/(100 +w) = 0.10

  30 = 10 +0.10w . . . . . simplify

  20 = 0.10w . . . . . . . . subtract 10

  20/0.10 = w = 200 . . . . divide by 0.10

200 kg of water must be added to dilute the solution to 10%.

Nolan is deciding between two truck rental companies. Company A charges an initialfee of $90 for the rental plus $2 per mile dri
kotegsom [21]

first we writte the information they are giving to us:

For company A:

initial fee = $90

rent per mile = $2

For combany B:

initial fee = $50

rent per mile = $3

Now for company A the equation that represent the charge in one mile will be: (where n is the number of miles)

\begin{gathered} A=90+2(n) \\ A=90+2(1) \\ A=90 \end{gathered}

And for company B:

\begin{gathered} B=50+3n \\ B=50+3(1) \\ B=53 \end{gathered}

Now to determine the number miles driven, that would make the cost of each company the same, we have to make A = B

\begin{gathered} A=B \\ 90+2n=50+3n \\  \end{gathered}

and finaly we can solve for n

\begin{gathered} 90-50=3n-2n \\ 40=n \end{gathered}

so if they drive for 40 miles the will pay the same
