Answer:
see below
Step-by-step explanation:
For the first question, you should multiply the scale dimension by 30 to get the actual dimension. This is because the scale is 1:30 where the scale dimension is the 1 and the actual dimension is 30, so therefore, the scale dimension is 1/30th of the actual dimension, so to get the actual dimension, we can multiply the scale dimension by 30. I'm not totally sure how to attach pictures from my phone on my computer (sorry) but an example of a drawing could be two rectangles, the first (this is the scale drawing) having dimensions of 1 by 2 units and the second (this is the actual drawing) having dimensions of 30 by 60 units. I hope this helps!
If the 4 states have to be in a specific order say ABCD,
then the total number of different possible routes is:
43P4 = 2,961,840
So the probability is:
1 / 2,961,840 = 3.38 x 10^-7
But if the 4 states can be in any order such as DBAC,
ACBD etc, then the total number of different possible routes is:
43C4 = 123,410
So the probability is:
1 / 123,410 = 8.1 x 10^-6
No I don’t think it is practical to list all the
different possible routes to select the one that is best. We can simply use
mathematical models to solve for that one.

15/50 simplified would be 3/10 (divided by 5 on each side)
5/9 x 3/10 would be 15/90 or 1/6
1/4 divided by 3/5 would be 5/12, because when you divide fractions you flip the second fraction Ex: 1/4 divided by 3/5 would be 1/4 x 5/3
The prime factorization of 120 would be 2 x 2 x 2 x 3 x 5 or 2^3 x 3 x 5
25% = 1/4
So to get the unknown number, multiply 9 by 4:
9 × 4 = 36
