b. In 1979, the estimated elephant population was 1.3 million and in 2007 it was 640,000. By approximately what percentage did t

saveliy_v [14]

Answer:

The initial amount, 1.3 million = 1,300,000 is the 100%.

now, 640,000 is a given percentage (lower than 100%) of that.

How we can find it?

suppose that 640,000 represents an x%.

Then we have that the quotient between the actual quantities and the percentages must be the same

(640,000/1,300,000) = x%/100%

x% = (640,000/1,300,000)*100% = 49.23%

Then the percentage declined is:

100% - 49.23% = 50.77%

The other question can not be answered with the given information.

Why does the United States purchase oil from other countries and the problem this sometimes causes

defon

Answer:

The oil produced in United States is light and low sulfur content and they do not have proper processing facilities, hence purchase it from other countries.

Explanation:

About 9.93 million barrels per day U.S purchase oil from 86 countries. Because the crude oil present is not homogeneous in nature. It is very light in nature with low sulfur content or may be high,this particular factor depends upon the method of the refining. Most of the oil are being exported by the Saudi Arabia and then comes Russia followed by Iraq. Despite the collapse in price, U.S. dependence on foreign oil should continue to decrease.
