A box contains 15 lbs.of books. There are 20 books in the box. How much does each book weigh?

Setler79 [48]

Answer:

0.75 lbs.

Step-by-step explanation:

Okay, this one is more simple. To find the weight of each book, You have to solve this division problem:

15/20

If you divided it the other way around, you would be saying each book weighed 1.33 pounds. That wouldn't be correct because then you would have over 20 lbs. of books, when you only have 15.

So, the answer is 0.75 pounds.

You can focus on the two sub-triangles ABC and ACD

We know that they are both right triangles, because we're given that AC and BD are perpendicular.

The sides AB and AD are the hypothenuses of these triangles, so we know their length through the pythagorean theorem:

$AD^2 = AC^2+CD^2$

$AB^2 = AC^2+BC^2$

But since we're given $BC=CD$ , the expressions for AD and AB are actually the same expression. This proves that AD=AB, and thus that the triangle is isosceles.
