A librarian put 42 books back on the shelves before lunch. Of the books, 14 were non-fiction. What is the ratio of the number of non-fiction books to the total number of books the librarian put away before lunch?

Answers

Answer:

Non fiction : Total number of books

= 14 : 42

= 1:3

Step-by-step explanation:

Total number of books = 42 books

Non fiction books = 14 books

The ratio of the number of non-fiction books to the total number of books is :

Non fiction : Total number of books

= 14 : 42

Further simplified

= 1:3

Solve the following equation.
-12d - 6 = -2(d + 3) - 10d

Answers

Answer:

All real numbers

Step-by-step explanation:

Distribute the -2 to the parentheses:

-12d - 6 = -2(d + 3) - 10d

-12d - 6 = -2d - 6 - 10d

Add like terms:

-12d - 6 = -12d - 6

Since each side is equivalent to -12d - 6, the answer is all real numbers

Answer:

This is true for any value of d. (d ∈ Set of All Real Numbers (I couldn't find the symbol))

Step-by-step explanation:

1. Simplify both sides. You cannot simplify -12d - 6, but you can simplify -2(d + 3) - 10d. Use the distributive property to simplify this. It would be -2d + -2 * 3 -10d, which is equal to -12d - 6. If you simplify both sides, you would get that d=d, which would be true for all values of d, which means that d is equal to all real numbers, meaning that for any value for d, this would be true (d ∈ Set of All Real Numbers (I couldn't find the symbol)).

five more than three times a number is 26 what is the number

Answers

Answer:

The required number is 7

Step-by-step explanation:

Let a number = x

We are given the condition: five more than three times a number is 26

We need to find the number.

Writing the condition in mathematical form:

five more than three times a number is 26: [tex]3x+5=26[/tex]

Now, solving this equation we can find x, the number

[tex]3x+5=26\\[/tex]

Subtract 5 from both sides

[tex]3x+5-5=26-5\\3x=21[/tex]

Divide both sides by 3

[tex]\frac{3x}{3}=\frac{21}{3}\\x=7[/tex]

So, we get: x = 7

The required number is 7

A shipping container will be used to transport several 100-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 26500 kilograms. Other shipments weighing 5300 kilograms have already been loaded into the container. Which inequality can be used to determine c, the greatest number of 100-kilogram crates that can be loaded onto the shipping container? Submit Answer 100c + 5300 26500 1000 + 5300 < 26500 26500 > 100(5300 + c) 26500 < 100(5300 + c)​

Answers

Answer:100c+5300<26500

Step-by-step explanation:

We are required to find the greatest number of 100-kilogram crates that can be loaded onto the shipping container

The the greatest number of 100-kilogram crates that can be loaded onto the shipping container is 212 crates

Greatest weight that can be loaded = 26500 kilograms

Weight of each crate = 100 kilogram

Weight of other shipment = 5300 kilograms

let

c = the greatest number of 100-kilogram crates that can be loaded

The inequality is

26500 ≥ 5300 + 100c

26500 - 5300 ≥ 100c

21200 ≥ 100c

c ≥ 21200 / 100

c ≥ 212

Coordinates of Points

A point is the basic relationship displayed on a graph. Each point is defined by a pair of numbers containing two coordinates.

A coordinate is one of a set of numbers used to identify the location of a point on a graph.

Identifying the x-coordinate

The x-coordinate of a point is the value that tells you how far from the origin the point is on the horizontal, or x-axis. To find the x-coordinate of a point on a graph:

- Draw a straight line from the point directly to the x-axis.

- The number where the line hits the x-axis is the value of the x-coordinate.

Identifying the y-coordinate

Now that you know how to find the x-coordinate of a point, you have to be able to find the y-coordinate.

The y-coordinate of a point is the value that tells you how far from the origin the point is on the vertical, or y-axis. To find the y-coordinate of a point on a graph:

- Draw a straight line from the point directly to the y-axis.

- The number where the line hits the axis is the value of the y-coordinate.

Notation for Identifying Points

Once you have the coordinates of a point you can use the ordered pair notation for labeling points. The notation is simple. Points are identified by stating their coordinates in the form of (x, y). Note that the x-coordinate always comes first.

Consider the equation below
a + 9 =23
3b + 9 =23
6c + 9 = 23

Determine whether each statement about the equations is true or false
​

Answers

Answer:

1. False

2. True

3. True

4. False

Step-by-step explanation:

a + 9 = 23

a = 14

3b + 9 = 23

3b = 14

b = 14/3

6c + 9 = 23

6c = 14

c = 14/6 = 7/3

Statement 1: 3a = 14 x 3 = 42, which is not equal to b.

Statement 2: 7/3 is less than 14.

Statement 3: 2c = 7/3 x 2 = 14/3 = b.

Statement 4: 6c = 14 = 3b, so the value of 6c is not greater than 3b. It is just equal to.

Greek actors traveled across the Athenian empire performing dramas and tragedies reflecting Greek ideals.correct answer pleas In 1800, Herschel wondered if the different colors of the rainbow were equal in brightness and heat. He used a prism to separate sunlight into it's different colors and thermometers to measure how much "heat energy" was included with each color. He also measured how much "brightness" was associated with each color. He noticed a "brightness" peak at the middle of the spectrum. Red and violet had the least amount of brightness with a "peak" at green and yellow. But for "heat energy", violet had the least and the amount of heat climbed more and more and showed no sign of a "peak" . His observations supported the idea that neither Brightness nor heat were evenly distributed between the different colors. Some colors had more brightness (green and yellow) and a different color had the most heat (red).But this lead to a new question. Did the "heat" exist even where there was no visible light and did it peak at wavelengths less than red. He did another set of experiments and found this to be the case. He again used a prism to separate sunlight into the colors of the rainbow. These colors were cast on a sheet of paper and a thermometer could be moved from one color to the next to measure the amount of heat. But this time, he moved the thermometers beyond the red light and made measurements on the paper where there was no visible light. He found the maximum amount of heat at wavelengths longer visible red light.When Herschel selected where to place his thermometer and then measure the temperature, which variable was the Independent variable.Question options:A.
