Answer:
$1246.90
Explanation:
Since the bike lost 
% of it's value and it now currently at $
, we have to do 20% * $1039 to find the amount of money lost. 20%*1039=207.8. We have to add it up to find the original value so 1039+207.8=$1246.8
<span>The addition and subtraction of negatively charged electrons can easily change an atom’s charge, because they perpetually spin in valence shells outside the nucleus. It is easier for a neighboring atom to share or steal an electron rather than a positively charged proton, which is found in the nucleus. It requires a strong energy input to split a proton free from other protons and neutrons. thus, the atoms lose or gain electrons from neighboring ones and become what is known as "ions". Hope it helped!</span>
Answer:
2. An object that transfers heat well
Explanation:
Conductors has closer molecules in which can bump into each other easily to help transfer thermal energy. Examples are iron, steel, gold, copper, and other metals.
Correct option:
The statement "America is the world’s number one producer of natural gas derived from shale oil" is True.
Shale gas:
- Shale, a form of sedimentary rock, is used to make shale gas, which is natural gas.
- Over the past ten years, shale gas has gained importance as a natural gas source in the United States. Interest has also grown in possible shale gas reserves in Canada, Europe, Asia, and Australia.
- With large production in the US and Canada, North America is the region that produces the most shale gas globally. Only Argentina and China have so far produced shale gas on a commercial basis outside of the US and Canada.
- The environmental dangers associated with shale gas production like, Induced seismicity from hydraulic fracturing has been known to cause earthquakes in three different places across the world and leaks of extraction waste and chemicals into water systems, the release of greenhouse gases during extraction, and the pollution brought on by the poor processing of natural gas have led to its suspension in numerous nations.
