Pelase answer the question in the picture

Mathematics
1 answer:
olchik [2.2K]3 years ago
3 0

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!

There are 172 South American animals in the Springdale zoo. That is 45 more than half the number of african animals in the zoo.
patriot [66]
N=number of African animals in the zoo;
we suggest this equation:
172=45+n/2
Least common multiple=2
172*2=45*2+n
344=90+n
n=344-90
n=254

Answer: there are 254 African animals in the zoo.

The price of a game that's been discounted<br> 18% off its list price (x)
Dmitry_Shevchenko [17]

Answer:

The price of a game is  0.82x

Step-by-step explanation:

Let

x ----> the list price of a game

Remember that

100\%-18\%=82\%=82/100=0.82

To find out the price of a game that's been discounted  18% off its list price, multiply the list price by the number 0.82

so

(x)(0.82)=0.82x

<h3>Answer:</h3>
  1. d. The y-intercept is 1 space higher.
  2. a. 9 to the power of -1/2
<h3>Step-by-step explanation:</h3>

1. Changing f(x) to f(x) + 1 adds 1 to every output value of the function, moving that value "1 space higher". This is true for the y-intercept, too.

___

2. The rules of exponents apply:

  • a^b · a^c = a^(b+c)
  • 1/a^b = a^-b

You apparently want to simplify ...

... 9^(1/4) × 9^(1/2) / 9^(5/4)

... = 9^(1/4 + 1/2 - 5/4)

... = 9^((1+2-5)/4)

... = 9^(-2/4) = 9^(-1/2)
