Answer:

He bought 17 books.

Step-by-step explanation:

Given that:

Total money spent = $89

Cost of each book = $5

Shipping price = $4

We have to find, Total number of books

So if the number of books be represented by b, the equation will become:

Cost of one book * total number of books + shipping price = total money

Putting values we get:

5*b + 4 = $89

By simplifying:

5*b = 89 - 4

5*b = 85

Dividing both sides by 5 we get:

b = 17

So the total number of books bought is 17.

i hope it will help you!

Given 6, 8, and 11 as the three sides of a triangle, classify it as one of the following:
Katyanochek1 [597]

Answer:

  C. Obtuse

Step-by-step explanation:

The "form factor" I use for this is ...

  a^2 + b^2 - c^2 = 6^2 + 8^2 - 11^2 = 36 +64 -121 = -21

The value is negative, indicating an OBTUSE triangle.

__

<em>Additional comment</em>

In this expression, 'a' and 'b' are the two shortest sides (in no particular order) and 'c' is the longest side. The interpretation is ...

  negative — obtuse

  zero — right

  positive — acute

__

If you're familiar with Pythagorean triples, you know that the 3-4-5 right triangle triple can be doubled to give 6-8-10. The long side of 11 is longer than the hypotenuse for the right triangle, so would correspond to a largest angle greater than 90°. The 6-8-11 triangle would be OBTUSE.
