Answer:

Rounded to the nearest hundredths: 11.69.
Step-by-step explanation:
I would use the Pythagorean theorem for this problem.
The difference between the highest point and the lowest point of AD is 9.8-7.2 = 2.6, so that would be the height of the triangle. The length/base of the triangle would be 11.4.
Now, just solve using Pythagorean's theorem:

Rounded to the nearest hundredths: 11.69.
I hope this helped you.
Answer:
5
Step-by-step explanation:
The easiest way to do this is to add the new members to the old and then divide by 11. Ignore the remainder.
13 + 52 = 65
65 / 11 = 5 with 10 left over. Ignore the 10. That's not a complete team.
The answer is 5
<u>Answer:</u>

<u>Step-by-step explanation:</u>
We are given the following expression and we are to simplify it:

To make it easier to solve, we can also write this expression as:

Now we will cancel out the like terms to get:

Taking the square root of the terms to get:
