Please give answer of 6 number

Irina18 [472]

Answer:

$7,500$

Step-by-step explanation:

Let's solve this problem step-by-step. The library had 1,500 books in 2011. The ratio of books in 2011 and in 2012 is 1:2. Therefore, let the number of books in 2012 be $x$ .

We have the following proportion:

$\frac{1}{1,500}=\frac{2}{x},\\x=2\cdot 1,500=3,000$

Therefore, there were 3,000 books in 2012. The ratio of books in 2012 and in 2013 is 2:5. Let the number of books in 2013 be $y$ .

We have:

$\frac{2}{3,000}=\frac{5}{y},\\2y=5\cdot 3,000,\\2y=15,000\\y=\boxed{7,500}$

Therefore, there were 7,500 books in 2013.

In the figure below, FJ and GI intersect at H to

Oksanka [162]

Answer:

Step-by-step explanation:

∠ FHI and ∠ JHI form a straight angle and are supplementary, thus

3x + x = 180, that is

4x = 180 ( divide both sides by 4 )

x = 45

Thus

∠ FHI = 3x = 3 × 45 = 135° → C
