The pages in nisha s book are numbered from 1.she found that total number of 501 digids are used to write all the page numbers. for example 2 digids for page number 23 and 3 digids for page number 101.how manny pages does the book have?

The number of pages in the book is 203.

Numbers 1 to 9 have 1 digit. This means that 9 pages in the book would have 1 digit. Numbers 10 to 99 have 9 digits. This means that 90 pages in the book would have 18 (9o x 2) digits. Numbers 100 to 199 have 300 (100 x 3) digits. This means that 100 pages in the book would have 3 digits.

Total digits left = 501 - (180 + 9 + 300)

= 501 - 489

= 12

Number of pages left = 12 / 3 = 4

Total number of pages in the book = 9 + 90 + 100 + 4 = 203 pages

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
