The most surprising thing for me personally was the set up of the trenches, there is a very good system where the front line is the first to attack or be attacked while the others are there as backups. If someone were to get hurt within the first trench, there are easily accessible routes for the soldiers to take to retreat to safety, on the contrary, if the front lines were in need of any reinforcement whatsoever, there is a clear way to travel for the soldiers to get more ammunition or man power.
Answer:
20 members of the rappelling club are going on the trip
Explanation:
Total cost of the trip is $540.
If only one person goes, the cost is $540.
We can make the total number of people going x since we are not given.
Therefore, each member would pay (540/x)
We can also rep 7 with non members since the number is given as 7
Total people going= Members + non members.
Therefore, the cost per person is now (540/x+7).
Problem.
540/x -540/x +7 = 7
Multiply each with lowest common denominator.
When you expand, you get
540(x+7) - x(540)/x(x+7) =7
Simplify multiplication.
540x+3780-540x=7(x^2+7x)
Combine like terms
540x-540x+3780=7x^2+49x
3780=7x^2+49x
7x^2+49x-3780= 0
When we divide through by 7, we have
x^2+7x-540
Factorize, we have
(x^2+27x)-(20x-540)=0
x(x+27)-20(x+27)=0
(x-20)(x+27)=0
x is therefore 20 or -27
Since we know -27 cannot be a reasonable answer hence must be excluded.
The exact number of the people going on the trip is 20.
Answer: b
Explanation: reforming the civil service and establishing the United States Civil Service Commission.
The correct answer should be the constitution because nobody is above the constitution. There are rules there on how the government is chosen, how it is changed, how it is kept in check, and if something is unconstitutional it is banned instantly by courts, and the government can't do anything that goes against the constitution.
