Rational of course, because 
and both 3 and 5 are relatively prime integers.
First one is 42
second is 24
Third is 12
Answer:
the cubes are 1 in on all sides
but...
since there's gaps its more likely that there a 1/2 in or 3/4 in
Step-by-step explanation:
12/12=1
Your vertex is (8,7)
First find the x intercept
-2/2a
X = 16/2
X = 8
Substitute the value x and solve for y
Youd get 7
Hence
(8,7)
The probability that the two socks match can be translated into the probability of getting two blue socks or two grey socks.
The combination ways for taking 2 socks from 16 socks would be: 16C2= 16!/2!14!= 120
Way to get 2 blue socks of 6 blue sock: 6C2= 6!/2!4!= 15
Way to get 2 grey socks of 10 grey sock: 10C2= 10!/2!8!= 45
Then the probability is: 15+45/ 120= 60/120= 1/2
