The student on the left end of the row can be any one of 30.
For each of those ...
The student in the next seat can be any one of the remaining 29.

The student in the next seat can be any one of the remaining 28.

The student on the right end of the row can be any one of the remaining 27.
The total number of ways to pick 4 students and seat them in the front row is
(30 x 29 x 28 x 27) = <em>657,720 ways.</em>
That's enough to do it a different way every school day for about 3,600 years !
(or until they all graduate, whichever comes first)

Answer:
Log (1/x) = –0.9925
Step-by-step explanation:
From the question given above, the following data were obtained:
Log x = 0.9925
Log (1/x) =?
Recall,
Log (M/N) = log M – Log N
Thus,
Log (1/x) = Log 1 – Log x
Recall
Log 1 = 0
Log x = 0.9925
Thus,
Log (1/x) = Log 1 – Log x
Log (1/x) = 0 – 0.9925
Log (1/x) = –0.9925
$263.50 were spent on 50 pounds of bulk goods.
Divide 50 from 263.50
263.50/50 = 5.27
The price per pound of bulk goods is $5.27
hope this helps
We can simplify second fratction by divide 2
4/2=2
6/2=3
2/(3xy^3)
common denomenator
factor
3x^2y=3*x*x*y
3xy^2=3*x*y*y
LCD=3*x*x*y*y=3x^3y^2
multiply first fraction by y/y and second fraction by x/x
(5y)/(3x^2y^2)-(2x)/(3x^2y^2)=
(5y-2x)/(3x^2y^2)
