on his shelves trenton has 15 biogrophies,15 science fiction books,7 refrence books,and 11 mystery books. find the ratio of biographies to the total number of books

Answer:

You have to substitute the x-values into the function :

[tex]f(x) = {11}^{x} [/tex]

[tex]f( - 2) = {11}^{ - 2} = \frac{1}{121} [/tex]

[tex]f( - 1) = {11}^{ - 1} = \frac{1}{11} [/tex]

[tex]f(0) = {11}^{0} = 1[/tex]

[tex]f(1) = {11}^{1} = 11[/tex]

[tex]f(2) = {11}^{2} = 121[/tex]

I'm a little rusty lol but I believe that is C, the distributive property.

Answer:

Total area of four walls is 450ft

Step-by-step explanation:

First to find area of one wall is lenghth times height 2(12 x 9)

Second to find the area of the two other walls it’s height times width 2(13 x 9)

third add then up and you get 450

Answer:

y > -1/4x + 4

Step-by-step explanation:

First find the equation of the line itself, which is y = -1/4x + 4, then determine if graph shades above the line or below the line. If it shades above which is true in this case, it will be greater than. If it shades below which does not occur in this case, it will be less than. Because the line is dashed and not solid, it will just be greater than or less than.

Therefore y = -1/4x + 4 → y > -1/4x + 4 [Shades above the line, line is dashed].

Answer:

-234

Step-by-step explanation:

1-235=-234

Answer:

Step-by-step explanation:

1-u=235  subtract the 1 from both sides

-u=234  divide by -1

u= -234

Answer:

Percent of occurrences= (Numbers of behavior/Numbers of opportunities)*100

Step-by-step explanation:

Based on the information given if a child is to put his/her plate in the sink everyday after having dinner the formula that will be use to calculates percent of occurrences is :

Percent of occurrences=( Numbers of behavior/Numbers of opportunities)*100

Where:

Numbers of behavior represent the Numbers of times the plate was put in the sink by child everday

Numbers of opportunities represent the Numbers of dinners the child had everyday

Answer:

20%

Step-by-step explanation:

26/130 = .2

decimal to percentage, times the decimal by 100

.2 x 100 = 20%

Answer:

4 games

Step-by-step explanation:

23 - 3 = 20

20 / 5 = 4

Answer:

1) They were multiplied by one power of ten because 2.5x 1^10 is 25, and so that it is easier to divide.

19.625/ 2.5 * 10/10 = 196.25/25

Answer:

0.875

Step-by-step explanation:

To find the decimal, you divide the 21 by the 24.

21/24 = 0.875

Answer:

b // f

c // e

Step-by-step explanation:

b // f

89.5 = 180 - 90.5

89.5 = 89.5       {corresponding angles are congruent.So b // f}

c//e

91.5 = 180 - 88.5

91.5 = 91.5    {corresponding angles are congruent.So b // f}

Answer: 1/27 is greater than 1 7/20 I believe.

Answer:

178.5mcg

Step-by-step explanation:

If you need 5000 per 125mcg, we can express it as;

5000 = 125mcg

To get the amount of mcg needed for 7140, we will say;

7140 = x mcg

Divide both expression

5000/7140 = 125/x

Cross multiply

5000x x= 7140 * 125

5000x = 892,500

x = 892,500/5000

x = 178.5

Hence the amount og mcg needed is 178.5mcg

Answer:

X-8 is the best answer there

Answer:

x=7

Step-by-step explanation:

This problem uses vertical angles! I'm sure you know this but just in case I will explain. Whenever there are two angles that are across from each other in a junction of two straight lines, they are perfectly equal! In this problem, the angles 6x-7 and 4x+7 are the same angle, so those equations have to have the same answer. In order to solve it, you need to write the equations like this:

6x-7=4x+7

From there you can solve for x. I will write my process here:

2x-7=7

2x=14

x=7

Just writing those vertical angle equations as equalities of each other should give you the answers you are looking for!
