Answer:
10.5 cm
Step-by-step explanation:
Since we know that O lies on AB we know that:
- The distance from the midpoint of OA to O is 6 cm (12/2).
- The distance from the midpoint of OB to O is 4.5 cm (9/2).
You can add 6 to 4.5 to get 10.5 cm.
Answer:
$173.90
Step-by-step explanation:
The most obvious way to answer this question is to multiply $9.40 by 18.5
This would result in 173.90.
But I realize nobody like to deal with decimals in a multiplication problem, so here's the way I would do it (<em>especially if you don't have a calculator!</em>)
The strategy is to break it down!
Multiply $9.40 x 18 hours to start, since this is easier.

So, that's $169.20 for 18 hours of work.
We aren't finished, because Abdel worked for 18.5 hours.
So, what half of $9.40?

= 4.7
-or-
$4.70
So, knowing that Abdel makes $4.70 in half an hour, lets just add that onto the $169.20 we got earlier.
169.2 + 4.7 = 173.9
-or-
$173.90 for 18.5 hours of work!

Answer:
22 feet
Step-by-step explanation:
Area of circle = pi(r²)
the square root of 121 is 11, so r = 11
d = 2r
d = 22
