a² + b² = c²

6² + 3² = c²

36 + 9 = c²

45 = c²

$\sqrt{45} = c$

$\sqrt{5 \times 3 \times 3} = c$

$\sqrt{5} \times 3 = c$

$3 \sqrt{5} = c$

Sixty percent of the books at a library are non-fiction. The library has about 15000 books. How many of the library’s books are

ddd [48]

There are 9000 non-fiction books in the library.

$100:60::15000:x\\$ represents the situation.

Step-by-step explanation:

Given,

Total books at library = 15000

Percent of non-fiction books = 60

Percent of all books = 100

Ratio of percent of books to non-fiction books = 100:60

Let,

x represent the number of non-fiction books.

Ratio of number of all books to non-fiction books = 15000:x

Using proportion

Ratio of percent of books :: Ratio of number of books

$100:60::15000:x\\$

Product of extreme = Product of mean

$100*x=15000*60\\100x=900000$

Dividing both sides by 100

$\frac{100x}{100}=\frac{900000}{100}\\x=9000$

There are 9000 non-fiction books in the library.

$100:60::15000:x\\$ represents the situation.
