Answer:
55 pages
Step-by-step explanation:
Knowing that the <em>book holds 600 cards and 6 cards/page</em>, we can tell that there are <em>100 pages</em>.
From that, we know that 45% are empty, which means <em>55% of all of the pages have cards</em>.
55% of 100 is 55. Therefore, 55 pages have baseball cards.

Answer:
8.4 (rounded to 1 dp)
Step-by-step explanation:
1) Identify the number of angles and sides given if you cannot use Pythagoras or SohCahToa.
2) You have 2 angles and 1 side, so you know you must use sine rule: <em>a </em>over sinA =<em> b </em>over sinB
<em>a</em> = side length, sin(A) = angle opposite side
<em>b</em> = side length, sin(B) = angle opposite side
3) This means:
13/sin(90) = x/sin(40)
4) rearrange for x:
x = 13/sin(90) * sin(40)
= 8.356...
5) Round to however many sig figs/dps they're asking for
Example: 1 dp
AB = 8.4
3 sig figs
AB = 8.36
