The teacher has 48 fiction books and 36 non-fiction books.

1) 4*12=48 3*12=36
2) 48+36=84
3)4:3 = 48:36

Since the ratio is 4:3, you can set the equation 7x = 84
and 4x = fiction, 3x = nonfiction.
x=12

so there are 48 fiction and 36 nonfiction

Answer: BC = 5.83

Step-by-step explanation:

Luckily, the triangle is placed on the graph nicely so we can count the legs of the triangle:

AB = 5

AC = 3

BC = ?

To find BC, we can simply use the Pythagorean Theorem:

$a^{2}+b^{2}=c^{2}$

5^2 + 3^2 = c^2

25 + 9 = c^2

34 = c^2

Now square root to find c, or BC.

$\sqrt{34}=\sqrt{c^{2} }$

c = 5.83 (rounded by nearest hundredth)
