Well id like to inform you but you got it right already its 3/4

Because to get your answer you would have to set up the equation  5 and 1/4

divided by 7 which would be 3/4 in a fraction or .75 decimal

Pelase answer the question in the picture
olchik [2.2K]

Answer:

B

Step-by-step explanation:

Notice that the equation shows KNO_3 going from a solid to an aqueous solution, which is dissolved. Entropy is essentially when a system becomes more disordered. Whenever we go from solid to liquid to gas, that's becoming more disordered because the molecules in the system are moving much more and in more random directions.

In addition, when we dissolve solids into water, that's another increase in entropy because we technically have a liquid component here and the molecules are now breaking apart.

So, the entropy here will increase.

Hope this helps!

What is the square root
shusha [124]

Answer:

Step-by-step explanation:

Trying to factor as a Difference of Squares :

1.1      Factoring:  r2-96

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 96 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares.

Equation at the end of step  1  :

 r2 - 96  = 0

Step  2  :

Solving a Single Variable Equation :

2.1      Solve  :    r2-96 = 0

Add  96  to both sides of the equation :

                     r2 = 96

When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:  

                     r  =  ± √ 96  

Can  √ 96 be simplified ?

Yes!   The prime factorization of  96   is

  2•2•2•2•2•3

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 96   =  √ 2•2•2•2•2•3   =2•2•√ 6   =

               ±  4 • √ 6

The equation has two real solutions  

These solutions are  r = 4 • ± √6 = ± 9.7980  

Two solutions were found :

                  r = 4 • ± √6 = ± 9.7980
