I believe it was called greenbacks.
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:
Initially, Department of State officials and Bush’s foreign policy team were reluctant to speak publicly about German “reunification” due to fear that hard-liners in both the German Democratic Republic (GDR) and the Soviet Union would stymie reform. Although changes in the GDR leadership and encouraging speeches by Gorbachev about nonintervention in Eastern Europe boded well for reunification, the world was taken by surprise when, during the night of November 9, 1989, crowds of Germans began dismantling the Berlin Wall—a barrier that for almost 30 years had symbolized the Cold War division of Europe. By October 1990, Germany was reunified, triggering the swift collapse of the other East European regimes.
Thirteen months later, on December 25, 1991, Gorbachev resigned and the Union of Soviet Socialist Republics dissolved. President Bush and his chief foreign policy advisers were more pro-active toward Russia and the former Soviet republics after the collapse of the Communist monolith than while it was teetering. In a series of summits during the next year with the new Russian President Boris Yeltsin, Bush pledged $4.5-billion to support economic reform in Russia, as well as additional credit guarantees and technical assistance.
The two former Cold War adversaries lifted restrictions on the numbers and movement of diplomatic, consular, and official personnel. They also agreed to continue the Strategic Arms Reduction Treaty negotiations (START), begun before the collapse of the Soviet Union, which set a goal of reducing their strategic nuclear arsenals from approximately 12,000 warheads to 3,000-3,500 warheads by 2003. In January 1993, three weeks before leaving office, Bush traveled to Moscow to sign the START II Treaty that codified those nuclear reductions.

True.
The reason why photographs capture images of distant galaxies much younger then they are at the moment the photograph was taken is because a picture that is taken can see what you see. What I mean is that you can see things because you're receiving the light produced by distant objects and by the time you can see distant objects the light has already been traveling. An Example of this is our sun when we look up and see our sun we're seeing about 8 minutes into the past because of the time it takes for light to travel from the sun to our planet.
Hope this helped.
