Here, Pages in books = Number of books * number of pages in one book
So, Pages of picture book = 10 * 25 = 250
& Pages of chapter book = 120 * 5 = 600
So, Number of Total pages = 250 + 600 = 850
So, Option (D) is your answer! Hope this helps!!

since there's 2 sides divide 8 by 2
8/2 = 4
4 is your answer.
hope this helps.
The half-life of carbon-14 is 5730 years, so you have
.. 0.662 = 2^(-t/5730) . . . . . . . . . . . . . . . . . t is age in years (before present)
.. log(0.662) = -t/5730*log(2)
.. t = -5730*log(0.662)/log(2) ≈ 3410 . . . . years
