Answer:
I'm going to write both of these because maybe you have a fill in the blank question. I don't know.

Simplify:

Step-by-step explanation:
is the equation of a circle with center (h,k) and radius r.
You are given (h,k)=(4,5) because that is the center.
You are given r=9 because it says radius 9.
Let's plug this in.

Simplify:

So if 54 is 100% then 200% is double therefore 200% of 54 is 108
Answer:
11 am
Step-by-step explanation:
Bus A and Bus B leave the bus depot at 9 am.
Bus A takes 30 minutes to complete its route once
Bus B takes 40 minutes to complete its route once.
We solve this finding the Lowest Common Multiple of the minutes each bus uses to complete it's route
30 = 3 × 10
40 = 4 × 10
= 3 × 4 × 10
= 120 minutes
120 minutes after 9 am is
60 minutes = 1 hour
60 minutes = 1 hour
= 2 hours.
9am + 2 hours
= 11 am.
Therefore, they be back at the bus depot together at 11 am
A-10, D-11, F-8, I-2, G-1, K-9, B-7, C-3
That's what I got so far, but I'm still working
14080 ft is the answer
hope this helps you
