If you use the 20% off coupon your total will be $16.80.
+ Purchase Price = $21
- Discount (21 x 20)/100 = $4.20
<span>= Final Price 21 - 4.20 = $16.80
</span>
If you use the $5 dollars off coupon your total will be $16.00.
$21 - $5 = $16.00

The better coupon to use would be the five dollars off coupon because $5 dollars off will be 80 cents less than using the 20% coupon.

21/100 gives you .21 then multiply by 20 to get 4.20$ and the 5$ is 5$ so it is worth more

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

9514 1404 393

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.
