Logan can read at a rate of 2/3 page per minute. At that rate, how many pages can he read in 2 hours?

Anon25 [30]

Answer:

240- 360

Step-by-step explanation:

You have to find out how many minutes in an hour which is 60. Then multiply it by 2 for 2 hours to get 120. Then you multiply 2x120 to get 240. Then you multiply 3x120 to get 360.

I'm not sure if this is correct but this is how I would go about it. :)

Sam is fencing in his property. The length is 12 feet less than twice the width. If the total amount of fence needed is 216 feet

DaniilM [7]

Answer:

L = 68 ft

Step-by-step explanation:

To find the perimeter of something you need to add up all the sides

In this case I am assuming Sam's property is a square/rectangle

Which means the formula for the perimeter is P = 2L + 2W

If L = 2W - 12 and P = 216, we can use these values and plug them into our perimeter equation to solve for w and then solve for l

216 = 2(2W -12) + 2W → ditributing the 2 to the (2w - 12) gives us
216 = 4W - 24 + 2W → combing like terms gives us
216 = 6W - 24 → adding 24 to both sides gives us
240 = 6W → dividing both sides by 6 gives us
40 ft = W

With the width being solved, we can now plug that value into our length equation

L = 2(40) - 12 → distributing the 2 to the 40 gives us
L = 80 - 12 → combing like terms give us
L = 68 ft

Pls do this quickly<br> Thank you

Answer:

288 cu in

Step-by-step explanation:

The Two end pieces

l = 6

w = 4

h = 4

V = l*w*h

V = 6*4*4

V = 96

But there are two end pieces. So the volume for both is 2 * 96 = 192

Middle Piece

L = 8

w = 4

h = 3

Volume = l * w * h

Volume = 8 * 4 * 3

Volume = 96

Total Volume

Total Volume = 96 + 192

Total Volume = 288 Cu in

Each page of a top-secret report on aliens requires 2 \text{ KB}2 KB2, start text, space, K, B, end text of space in digital for

fredd [130]

The maximum number of pages the report can have, using scientific notation, is of:

2 x 10^6.

<h3>What is scientific notation?</h3>

A number in scientific notation is written as follows:

$a \times 10^b$

With the base symbolized $a \in [1, 10)$ , meaning that it can assume values from 1 to 10, with an open interval at 10 meaning that for 10 the number is written as 10 = 1 x 10¹, meaning that the base is 1.

For this problem, the maximum number of pages that the report can have is given by the following division:

Maximum number of pages = Total capacity/Size of page.

These variables, from the text, are given as follows:

Total capacity: 4 x 10^6 KB.

Size of a page: 2 KB / page.

Hence the number of pages is obtained as follows:

Maximum number of pages = 4 x 10^6 KB / (2 KB/ page) = 2 x 10^6 pages.

When two numbers are divided in scientific notation, the bases are divided(4/2 = 2), while the exponents are subtracted (6 - 0 = 6).
