A chemist has one solution that has 50% acid. She has another solution that is 25% acid. How many liters of the 50% acid solutio
Tatiana [17]

Answer:

Step-by-step explanation:

Let's begin by assigning letters to represent our two unknowns:

   x (liters of 25% solution)

   y (liters of 50% solution)

 

Our system of equations will consist of two equations:

   Equation #1 (total volume of solution)

   Equation #2 (total concentration of acid)

 

Our total volume of solution is 10 liters, which can be expressed as the sum of our unknowns:

   Equation #1:  x + y = 10

 

Our total concentration of acid can be expressed as the sum of the individual acid concentrations to make up the concentration of the final solution:

   Equation #2:  (0.25)(x) + (0.50)(y) =

                            (0.40)(10)

 

We can use Equation #1 to express one unknown in terms of the other and then plug that expression into Equation #2 to solve for one of the unknowns:

   x + y = 10

         y = 10 - x

 

Now we'll plug our expression for y in terms of x into Equation #2 and solve for x:

   0.25(x) + 0.50(10 - x) = 0.40(10)

   0.25x + 5 - 0.50x = 4

   -0.25x = 4 - 5

   -0.25x = -1

          x = (-1)/(-0.25)

          x = 4 (liters of 25% solution)

 

Now we'll plug our value for x into Equation #1 and solve for y:

   4 + y = 10

         y  = 10 - 4

         y = 6 (liters of 50% solution)

 

Finally, we will verify the correctness of our answers by plugging these values into Equation #2 to see if the sum of the component acid concentrations equals the final solution concentration:

   0.25(4) + (0.50)(6) = 0.40(10)

   1 + 3 = 4

         4 = 4 (our answers are correct)

What is a simpler form of the radical expression?<br><br> SOMEONE PLEASE HELP!!
Brilliant_brown [7]

Answer:

Choice B

Step-by-step explanation:

Given radical expression:

\sqrt[4]{1296 {x}^{16}  {y}^{12} }

To Find:

The Simpler form of this expression

Soln:

=  \sqrt[4]{1296 {x}^{16}  {y}^{12} }

We could re-write the given expression, according to the law of exponents:

=  \tt \sqrt[4]{(6x {}^{4}y {}^{3})  {}^{4}  }

Now we need to bring terms out of the radical as:

\tt =   | 6x { }^{4} y {}^{3}  |

Bring out 6x^4 from the absolute & put y^3 only in it:

\tt = 6x {}^{4}  |y {}^{3} |

Choice B is accurate.
