Chemoautotrophs use ___ as an energy source and __

Once you have your heap structure created, next you must use it as a backing structure to a priority queue. Develop a PriorityQu

Using the knowledge in computational language in python it is possible to write a code that Develop a PriorityQueue data structure in a file.

<h3>Writting the code in python:</h3>

Which situation is the best example of opportunity cost? A country chooses to produce bananas instead of wheat. A country choose

Citrus2011 [14]

The correct answer is A. Country chooses to produce bananas instead of wheat.

Opportunity cost is termed as value of choice. It is the important concept in economics and also the relationship which is between choice and scarcity.

A good example of opportunity cost is you can spend money and time on other things but you can not spend time reading books or the money in doing something which can help.

Opportunity takes important part in economic theory.

The property taxes in a town decrease as the distance from the local elementary school increases. The greatest property taxes ar

Ann [662]

To solve this question, we will need the help of the picture attached:

1. According to this, every 101010 miles from the elementary school (Assuming the school is in point 0 of the line) the property taxes decrease 0.5%.

2. We also know that the greatest value in property taxes is 4.5%, and this decreases every 101010 miles.

So, if we draw a line divided in sections of 101010 miles and taking into account the data given, we have to sum each 101010 miles section until we get to the property tax value of the house, which is 3% in this problem.

Then, the distance from the school to the house, taking into account the 0.5% decrease with the distance is:

303030 miles
