Step 1: Define

[RxN]   2NO₂ ⇆ N₂O₄

[Equilibrium Rate Law]   [tex]\displaystyle K_c = \frac{[N_2O_4]}{[NO_2]^2}[/tex]

NO₂ = 11.95 M

N₂O₄ = 6.05 M

Step 2: Find K

This value of K tells us that the reactants are favored in the equilibrium reaction (K < 0.1).

The third table

Step-by-step explanation:

It's the third table because each input does not repeat, so it means all of the inputs are unique

Repeating inputs (x) make it not a function

As their is no mention of test assuming it's not a test question

Solution

Now

As per definition of function

Every domain has an unique rangef(x)=y

The line plots shows the weights of 9 grapefruits. What is the difference in the total weight of all the 1 1/2 lb grapefruits and the total weight of all the 1 1/4 lb grapefruits? A 1/4lb B 2 lb C 4 1/2lb D 7 lb

Answers

Answer:

The difference of weight is [tex]2[/tex] pounds.

Step-by-step explanation:

Given:  The line plots shows the weights of [tex]9[/tex] grapefruits

To find: The difference in the total weight of all the [tex]1\frac{1}{2} lb[/tex]  grapefruits and the total weight of all the [tex]1 \frac{1}{4}lb[/tex] grapefruits.  

Firstly, we need to convert the given mixed fractions as following:

[tex]1\frac{1}{2} lb=\frac{2+1}{2}=\frac{3}{2}lb[/tex]

[tex]1\frac{1}{4} lb=\frac{4+1}{4}=\frac{5}{4}lb[/tex]

Now, we know that,

Point diagrams divide a sample into different classes, and allow to observe the frequencies of each class.

In this case, the different weights of the grapefruit constitute the classes. From a sample of 10 grapefruit, some will weigh  others weigh.

We need to observe the dot diagram to know how many  grapefruit we have of weight [tex]\frac{3}{2} lb[/tex] and how many  grapefruit we have of weight [tex]\frac{5}{4} lb[/tex]. In other words, we need to know, in the diagram, how many points there are about class of  [tex]\frac{3}{2} lb[/tex] and how many points there are about class of   [tex]\frac{5}{4} lb[/tex].

Then, the total difference between all grapefruit of  pounds and all grapefruit of pounds is calculated as follows:

[tex]x (1\frac{1}{2} ) - y (1\frac{1}{4} ) = Z[/tex]

Where

[tex]Z[/tex]: Weight difference

[tex]x[/tex]: Quantity of [tex]1\frac{1}{2} lb[/tex]  grapefruit

[tex]y[/tex]: Quantity of [tex]1\frac{1}{4}lb[/tex] grapefruit

Suppose that of the [tex]10[/tex] total grapefruits, [tex]3[/tex] of them weigh [tex]1\frac{1}{2} lb[/tex]  and [tex]2[/tex] of them weigh [tex]1 \frac{1}{4}[/tex]  pounds. This is: [tex]x=3[/tex] and [tex]y=2[/tex]

Now,

[tex]3(\frac{3}{2} )-2(\frac{5}{4} )[/tex]              

[tex]=\frac{9}{2} -\frac{5}{2}[/tex]                    

[tex]=\frac{4}{2}[/tex]            

[tex]=2[/tex]

Hence, for this case, the difference of weight is [tex]2[/tex] pounds.

3x + 10 = 4x +54. How did you get your answer?

Answers

Answer:

[tex]x=-44[/tex]

Step-by-step explanation:

[tex]3x+10=4x+54[/tex]

To solve for the variable [tex]x[/tex], start by subtracting [tex]3x[/tex] from both sides of the equation:

[tex]10=x+54[/tex]

Then, subtract [tex]54[/tex] from both sides of the equation:

[tex]-44=x[/tex]

Therefore, [tex]x=-44[/tex]

-

To check your work, simply substitute the solved value of [tex]x[/tex] into the initial equation:

[tex]3(-44)+10=4(-44)+54[/tex]

Multiply:

[tex]-132+10=-176+54[/tex]

Add:

[tex]-122=-122[/tex]

Since both sides of the equation are equal to each other, our solution is correct!

Answer:

[tex] = > 3x + 10 = 4x + 54[/tex]

We need to get the x on the one side and the numbers on the other.

Subtract 3x from both sides:

[tex] = > 3x - 3x + 10 = 4x - 3x + 54[/tex]

[tex] = > 10 = x + 54[/tex]

Subtract 54 from both sides:

[tex] = > 10 - 54 = x + 54 - 54[/tex]

[tex] = > - 44 = x[/tex]

Thus,the value of x is -44.

For checking:

[tex] = > 3x + 10 = 4x + 54[/tex]

[tex] = > 3( - 44) + 10 = 4( - 44) + 54[/tex]

[tex] = > - 132 + 10 = - 176 + 54[/tex]

[tex] = > - 122 = - 122[/tex]

Through which point must the graph of y = 4 logs (x) + 2 pass?
A. (5,6)
B. (5,8)
C. (5, 12)
D. (5, 40)

Answers

The graph of y = 4 logs (x) + 2 passes through the point (5,8).

The given equation of the graph is y = 4 logs (x) + 2

We have to find the point which passes through the graph

The equation y = 4 logs (x) + 2 can be rewritten as y = log(x⁴) + 2. Substituting x = 5 into the equation gives us y = log (5⁴) + 2

= log (625) + 2

= 8.

Therefore, the graph of y = 4 logs (x) + 2 passes through the point (5,8).

Jason is baking a cake. The recipe calls for 2 cups of sugar for every 5 cups of flour. If he is making a small cake and is only using 1 cup sugar, how many cups of flour should he use? *

Answers

Answer:

2 1/2 cups

Step-by-step explanation:

First, our ratio is sugar:flour or 2:5, so our question is 1:? We find ? by finding how we got to 1 on the other side.

2 ÷ 2 = 1

And what we do to one side, we always have to do to the other to make it proportional, so

5 ÷ 2 = 2.5 or 2 1/2

So, if Jason is using 1 cup of sugar, he should use 2 1/2 cups of flour
