The pages of a book are numbered and it's found that 495 digits are used How many pages were there?
There are 9 pages that use a single digit (pages 1-9), leaving 495 digits - 9 pages × 1 digit/page = 486 digits There are 90 pages that use 2 digits (pages 10-99), leaving 486 digits - 90 pages × 2 digits/page = 306 digits There are 900 pages that use 3 digits (pages 100-999); this would be 2,700 digits, so the number of pages is somewhere in the hundreds. 306 digits ÷ 3 digits/page = 102 pages in the hundreds. → total number of pages = 102 + 90 + 9 = 201 pages.
852 digits used to number the pages of a book how many numbered pages does the book have?
There are exactly 320 pages in 852 digits.
The sum of the page numbers on the facing pages of a book is 89. What are the page numbers?
They are 44 and 45.
The sum of the page numbers on two facing pages is 245 the product of the numbers is 15006 what are the page numbers?
122 and 123How?|vif the page is double sided then it has two numbers that are added... divide 245 by 2 and you get 122.5 so one page is pg. 122 and the other is pg. 123
What is the unit rate of 15 pages in 30 minutes?
2 pages per minutes
When 151 digits are used to number a book how many pages are there?
First 9 pages = 9 digit. That leaves 142 digits. @ 2 digit per page, that is 142/2 = 71 pages with 2-digit numbers. So, 9 pages with 1-digit numbers + 71 pages with 2-digit numbers = 80 pages.
How many digits are used for printing the page numbers of abook that has 215 pages?
If all pages are numbered (usually page 1 is not numbered) then 537.
Carlin wrote a 447 page book on the history of mathematics. She numbered the pages by hand beginning with page 1. How many total digits did she write when numbering the pages?
Answer1 x 9 (number of 1 digit numbers) plus 2 x 89 (number of 2 digit numbers) plus 3(number of 3 digit numbers) x 347 = 1228 The correct answer is 1323. Here is how you do it.1 digit numbers = 92 digit numbers = 90 (99-9) number of 2 digit numbers - number of 1 digit numbers3 digit numbers = 378 (477-99) number of 3 digit numbers - number of 1 & 2 digit numbersSo, the solution is:1x9 = 92x90 = 1803x378 = 11349+180+378 = 1323
When numbering the pages of a book 624 digits were used find the number of pages in the book?
This problem can be solved by applying the counting principle to digits in consecutive page numbers. To begin, we need to separate numbers into their numbers of digits in order to multiply the page numbers to find the number of digits needed to express them. Assuming that your book begins on page 1, there are 9 page numbers having one digit only (counting principle: 9 - 1 + 1 = 9). Since each of these pages is numbered with one digit, the number of digits used is 9 so far. Continue with the pages each numbered with two digits. These are pages 10-99, comprising 90 pages (99 - 10 + 1 = 90). Every page number multiplied by 2 digits each is 180. With the 9 digits coming from single-digit pages, the number of digits used so far is now 189. We can continue in the same manner for pages expressed with three digits, 100-999, but having 435 (624 total - 189 so far = 435) digits left, we probably won't be able to get through all the three-digit numbers. Also, a book is likely to have under a thousand pages. To find out how many pages are left, we divide the number of digits left by the number of digits needed for each page: 435/3 = 145 pages left. Since 145 pages only account for the pages numbered with three digits each, we need to add pages numbered with one and two digits each in order to find the total number of pages. Before 145 pages began to be accounted for, we had accounted for the digits of 99 pages (each numbered using one or two digits each), so the total number of pages is 99 + 145 = 244.
Do books have even numbered pages on right or left?
even numbers are on left
If the pages of a certain book are all numbered in order from 1 through 246 how many digits altogether are used?
Well, the simplest way to do this is to break the page numbers down into groups. Numbers 1-9 have 1 digit. Numbers 10-99 have 2. Numbers 100-246 have 3. Thus we have 9 one-digit numbers, 90 two-digit numbers, and 147 three-digit numbers. Therefore: (9)(1) + (90)(2) + (147)(3) = 630 digits.
How many odd numbered pages in 356 pages?
178 odd numbered pages in 356 pages.
What are odd pages?
The odd pages are just the pages that don't have even numbers... every other one. So, pages 2 and 4 are even, and pages 3 and 5 would be odd pages, because they are numbered with odd numbers. :) You could also say that pages are odd if there is something odd about them, for instance size or printer errors. But in general when someone says "odd pages" they will mean the odd numbered ones.
What is the term for pages that appear as a two-page spread with odd-numbered right pages and even-numbered left pages?
This is called Facing pages in Microsoft Word.
In a book with 382 pages how many 3's would be used to number the pages?
Oh, what a lovely question! Let's take a moment to appreciate the beauty of numbers. In a book with 382 pages, the number of times the digit 3 is used to number the pages would depend on how the pages are numbered. If we're counting individual pages (1, 2, 3...), you would find the digit 3 used 60 times. If we're counting in sets of 10s (10, 20, 30...), you would find the digit 3 used 40 times. Just like painting, it's all about perspective and how you choose to look at things.
Should Page numbers appear on all pages of a business plan?
This depends on the numbering protocol being followed. If the pages are being numbered from the cover, then it is not usual to number the cover or the contents pages, and the page after the contents page is the first one with the plan's text on it, and is numbered 3. Otherwise the page after the contents can be numbered 1. An appendix or appendices (if any) should be numbered in a different format from the body of the report - usually lower-case roman numerals are used.
