Answer:
Extreme weather conditions
Polar ice melting
Acidification of oceans
Explanation:
Global warming is a phenomenon that refers to increase in temperature of the earth surface as a result of the concentration in the amount of greenhouse gases in the atmosphere. Greenhouse gases like carbon dioxide, methane, water vapour in their normal amount helps to trap some part of solar radiation which is useful for all life on earth. If the proportion of these gases increase beyond normal, more radiation will be trapped and a surge in surface temperature results. This increase in temperature leads to:
- Extreme weather conditions: Hurricanes, tornadoes becomes more prevalent as there is more heat in the atmosphere.
- Polar ice begins to melt as a result of increase in the temperature of the earth surface.
- Due to surge in the amount of carbon dioxide on the earth, the ocean dissolves the gases and this leads to the formation of weak carbonic acid.
Answer:
- $60
- 103 sales
Explanation:
1. The sweater was originally priced at $80 and then got marked down by 25%. The new price is;
= 80 * ( 1 - 25%)
= 80 * 0.75
= $60
2. Terry earns a basic salary of $250 plus $5 per sale. To make a total of $765, from sales commission alone Terry must make;
= 765 - 250
= $515
Sales to make = 515/5
= 103 sales
