Step-by-step explanation:
Area =lw
=2x (8+1)

=18x
therefore the area is 18x
Answer:
getting the queen is smaller
5/8
Step-by-step explanation:
There are 4 queens in a 52 card deck
P(queen) = 4/52 = 1/13
There are 12 pairs socks, 3 of which are grey
P(grey socks) = 3/12 = 1/4
1/13 <1/4
So getting a queen is smaller
The possible outcomes
8 +0 9+0 10+0 <em> 11+0</em>
8+1 9+1 <em> 10+1 11+1</em>
8+2<em> 9+2 10+2 11+2</em>
<em>8+3 9+3 10+3 11+3</em>
There are 16 outcomes and 10 of them are after 11, (assuming we add the time to the bedtime)
P (bedtime later than 10) = 10/16 = 5/8
The answer is x equals 1/2.
3276800/8 = 409600 (how many bacteria in an hour)
Then just multiply that number by the amount of hours you want to solve for
9 hours = 3686400
10 Hours = 4096000
