To solve this problem you must use Permutation:
You want to made 4 digit numbers with the digits 1, 2, 3, 4, 5, 6 and<span> no digit can be used more than once. So, we have:
(A,B,C,D)
A can variate in six (6) differents forms.
B can variate in (6-1)=5 differents forms.
C can variate 4 digits.
D can variate 3 digits.
Keeping this on mind, we have:
=6!/2!
=6*5*4*3
=360
</span> The answer is: 360

Step-by-step explanation:
triangles are congruent
sp
kj/nm=kl/lm=jl/ln
40/16=x/14
5/2 = x/14
x=35
5/2=45/y
y = 18
Answer:
At 1:25 P.M.
Step-by-step explanation:
Thomas arrived at the library at 11:45 AM and he left 1 hour 40 minutes later.
So, 1 hour 40 minutes is equivalent to (60 + 40) = 100 minutes.
Now, after 15 minutes, the time will be 12 P.M.
So, remaining (100 - 15) = 85 minutes i.e. 1 hour and 25 minutes the time will be 1:25 P.M.
Therefore, Thomas leaves the library at 1:25 P.M. (Answer)
