Answer:
payback period is 9.4785 ≅ 9.5 years
Explanation:
BTU stands for British thermal units and MCF stands for the volume of 1,000 cubic feet.
We know that one thousand cubic feet (Mcf) of natural gas equals 1.037 million Btu.
Difference between heat loss before and after installation = (42-28) millions BTU = 14 millions BTU
14 million BTU is equivalent to --
1.037 million BTU = 1 MCF
1 million BTU = (1/1.037) MCF
14 million BTU = (1/1.037) x 14 MCF = 13.5004 MCF
Cost of 13.5004 MCF = = $8.94 x 13.5004 = $120.6935
Pay back period = (1144/120.6935) = 9.4785
Therefore, her payback period is 9.4785 ≅ 9.5 years
Answer:
The Scientific Revolution was a series of events that marked the emergence of modern science during the early modern period when developments in mathematics, physics, astronomy, biology, and chemistry transformed the views of society about nature. The Scientific Revolution took place in Europe towards the end of the Renaissance period and continued through the late 18th century, influencing the intellectual social movement known as the Enlightenment. While its dates are debated, the publication in 1543 of Nicolaus Copernicus' De revolutionists erbium celestial is often cited as marking the beginning of the Scientific Revolution.
Explanation:
All of the above. Haiti is located near a major fault zone, half of its population at the time lived in densely populated urban areas; their weak government, which is a remnant of colonial impact, is very poor for the same reason and therefore did not have buildings up to code regarding earthquakes.
Not sure about poor soil but it probably didn't help if that is true. Islands aren't exactly famous for a lot of quality soil (large amount of sand which is unstable).
