First, convert 3 1/2 into an improper fraction, which is 7/2. Now, you have to make sure both sides have a common denominator. This will be 6. So now the equation is 21/6 - 4/6. Subtract the numerators, which is 17. Keep the denominator, however. Now, simplify. You new answer will be 2 5/6.

Not a right triangle. See below for my reasoning.
Step-by-step explanation:

Mr.Josol : what will be the height of the ball after 2 seconds?
Answer:
2.69 x 
Step-by-step explanation:
We are given the heart's speed - 70 bpm
We count the number of minutes in 73 years :
- 1 year = 365 days
- 1 day = 24 hours
- 1 hour = 60 minutes
- 73 x 365 x 24 x 60 = 38,368,800 minutes
We multiply the heart's bpm with 73 years worth of minutes
38,368,800 x 70 = 2,685,816,000
Write the number in scientific notation = 2.68581 x ≈ 2.69 x
