Answer:

The triangle is a right triangle

Step-by-step explanation:

We use the pythagorean Theorem which is a^2+b^2=c^2

Now we have 12^2+16^2=20^2

Solve: 144+256=400

400=400

1. 624 students

If you multiply .24 (24%) by 2600, you'll find that the answer is 624.

2. 11% increase in protein

Divide 48 by 54 (48 ÷ 54), you'll notice the answer is around 0.88888. Next subtract 0.88888 by 1. The answer will be around 0.11111.

3. 44% sale

Divide 200 by 360 (200 ÷ 360). The answer will be around 0.5555555556. Next, subtract this number from 1. THIS answer is equal around 0.4444444.

4. 9 players were NOT eligible

Multiply 60 by 0.85 (85%). The answer to this is 51. Subtract 51 from the original number (60). The answer is 9.

5. 420 students plan to go to college

Multiply 1200 by 0.35 (35%). The answer to this is 420.

6. 20% don't have an Instagram account

To make this easier, we'll double to statistics (instead of 4 out of 5, it's 8 out of 10). 8 divided by 10 = 0.8. Subtract 0.8 from 1. Now, you have you're answer: 0.2 or 20%.

I hope this helps! Sorry if some were incorrect. :)
