There are 5 new books and 7 used books on a shelf. What is the ratio of new books to all books?

Answers

Answer 1

Answer:

The ratio of new books to all books is 5:12.

In this scenario, there are 5 new books and 7 used books on a shelf. We will determine the ratio of new books to all books and explain it mathematically.

To find the ratio of new books to all books, we need to compare the number of new books to the total number of books, which includes both new and used books. In this case, there are 5 new books and 7 used books, so the total number of books is 5 + 7 = 12.

Now, let's define the ratio of new books to all books using the mathematical notation. We'll use "n" to represent the number of new books, "u" to represent the number of used books, and "t" to represent the total number of books.

Let:

n = 5 (number of new books)

u = 7 (number of used books)

t = n + u = 5 + 7 = 12 (total number of books)

The ratio of new books to all books is given by n/t. Substituting the values, we get:

Ratio of new books to all books = 5 / 12

The ratio can also be expressed in fractional form as 5/12. This means that out of every 12 books on the shelf, 5 are new books, and the remaining 7 are used books. The ratio is simplified to its lowest terms, making it a concise representation of the relationship between new books and all books on the shelf.

Answer:

t = 51

Step-by-step explanation:

Given

360 = 20 $√(t+273)$ ( divide both sides by 20 )

18 = $√(t+273)$ ( square both sides )

18² = t + 273, that is

t + 273 = 324 ( subtract 273 from both sides )

t = 51

A farmer collected 12 dozen eggs from her chickens. She sold 5/6 of the eggs to the farmers market and gave the rest to friends and neighbors. How many dozens of eggs did the farmer give away

Answers

Multiply 12 x 12 which is 144. And then you divide that by 6 and you get 24

She collect 12 dozens , a dozen = 12

12 Dozens = 12 * 12 = 144

She gave 1/6 to her friends and family, to find 1/6 you divide it.
144 / 6 = 24
24 = 1/6

She gave 24 to her friends and family

What happens when you move to the left of a decimal point?

Answers

If you move left of a decimal point, that means that the number is decreasing like for example:
45.89 to a decimal point - 4.589

I hope this helped!

When you move a decimal point to the left $n$ times, the number becomes $10^n$ times smaller.

Which two points should the line of best fit go through to best represent the data in the scatterplot? On a graph, points are at (1, 16), (2, 15), (3, 14), (4, 9), (5, 8), and (6, 1). (1, 16) and (2, 15) (1, 16) and (6, 1) (2, 15) and (4, 9) (5, 8) and (6, 1)

Answers

Answer:

C. (2, 15) and (4, 9)

Step-by-step explanation:

The line of best fit in a scatterplot is a straight line that shows the relationship among the data. It is drawn in such a way that it groups the points evenly on each side of the line. It is used when a straight line could not be drawn through all or major number of points plotted on the graph.

From the question, when points (1, 16), (2, 15), (3, 14), (4, 9), (5, 8), and (6, 1) are plotted on a graph, the line of best fit would go through points (2, 15) and (4, 9). This would achieve an even spread of the points on the two sides of the line.

Answer:

C. (2, 15) and (4, 9)
