Based on the information given, the number of fiction books will be 22.

Based on the information given, it was stated that there are 2/ 5 as many fiction books as there are nonfiction books and there are 56 books in the school library.Therefore, the number of fiction books will be:

= 2/5 × 56

= 22

Therefore, there are 22 fiction books.

Answer from: mercedesamatap21hx0

Step-by-step explanation:

Let the number of non-fiction books be x .

Then the number of fiction books= $\frac{2}{5}x$

Since, there are 56 books in the school library.

Then, $\\\Rightarrow\frac{2}{5}x+x=56$

$\frac{2x+5x}{5}=56\\\Rightarrow\ \frac{7x}{5}=56\\\Rightarrow\ x=\frac{56\times5}{7}\\\Rightarrow\ x=40$

Hence, the number of non fiction books = 40

Therefore, the number of fiction books = $\frac{2}{5}40=16$

Answer from: Quest

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

$ab^2+ac^2=bc^2$

$ab^2+ac^2=x^2$ )

triangle abd and cba are similar,

$\frac{ab}{bc}=\frac{bd}{ab}$

$ab^2=bc\cdot bd$

$25=bc\cdot bd$ (2)

triangle cad and cba are similar,

$\frac{ac}{bc}=\frac{cd}{ac}$

$ac^2=bc\cdot dc$

$7\times 7=bc\cdot dc$

$49=bc\cdot dc$ )

using (1), (2) and (3), we get

$25+49=x^2$

$74=x^2$

hence proved.

therefore option 2 is correct.

Answer from: Quest

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
