The Dewey Decimal Classification System is a method used to calssify books in the library. It was named after Melvil Dewey who developed it in 1876. The system uses numbers to organize the subjects of each nonfiction books and are divided into 10 main subject groups called categories. Each category is presented by a figure starting from 000 to 999. Each number presents a special topic. Books with the same number are placed in alphabetical order by the last name of the author. The first digit of a three digit number signifies the main class. Suppose you have 500, the 5 in signifies natural sciences and mathematics. The second digit signifies the division and the last digit signifies the sections.

Mark wants to fence 4 rectangular gardens, each with a length of 9 1/4 feet and a width of 4 1/2feet. What is the length of fenc

kolbaska11 [484]

Answer:

110 ft

Step-by-step explanation:

The length of fencing is four times the perimeter of one garden.

The formula for the perimeter of a rectangle is

P = 2l + 2w

The total perimeter for all four rectangles is

P = 4× (2l + 2w) = 8l + 8w

Data:

l = 9¼ ft

w = 4½ ft

Calculation:

P = 8l + 8w = 8×9¼ + 8×4½ = 72⁸/₄ + 32⁸/₂ =(72 + 2) + (32 + 4) = 74 + 36 = 110 ft

The total length of fencing is 110 ft.

What is the Width, explain how you got your answer (8 points btw)

asambeis [7]

Answer:

Based off of my calculations, I got 126

Step-by-step explanation:

The formula for area would be: A = L * W

So, when finding the width (W), you would need to divide the area (A) by the length (L).

Equation: W = A / L

Now you know the equation, all you need to do is plug in the numbers:

[84 divided by 2/3]

W = 84 / 2/3

After solving this, you would get: 126

So, W = 126.

To check if we got the correct answer, we could just multiply the length times the width:

126 * 2/3

Since this equation gives us 84 as the answer, 126 is the correct width.

What is the solution to the inequality

Dvinal [7]

Answer:

p > 5 and p <-8

Step-by-step explanation:

To solve this, you first need to isolate p.

First add 6 on both sides of the equation:

$-6 + |2p+3| >7\\\\(+6) -6 + |2p+3| >7 +6\\\\2p + 3 > 13$

Then subtract 3 from both sides of the equation.

$2p+3-3>13-3\\\\2p > 10\\$

The divide both sides by 2.

$\dfrac{2p}{2}>\dfrac{10}{2}\\\\p>5$

Another solution is possible because of the absolute value.

If $|2p+3|>13$

Then $|2p+3|$

<em>Thus we can solve the second solution:</em>

$|2p+3|$

$2p+3$

Isolate P again by subtracting both sides by 3

$2p+3-3$

$2p$

Then divide both sides by 2:

$\dfrac{2p}{2}$

$p$
