The Smiths went to dinner at Cheesecake Factory and their bill was $123.75 plus 7.5% sales tax. What is the total bill? Round to the nearest cent.
The total bill that was given to the Smiths at the Cheesecake factory was $133.03
An equation is an expression used to show the relationship between two or more numbers and variables.
Given that the Smiths bill was $123.75 plus 7.5% sales tax. Hence:
Total bill = $123.75 + Sales tax
Sales tax = 7.5% of bill = 0.075 * $123.75 = $9.28
Total bill = $123.75 + $9.28 = $133.03
The total bill that was given to the Smiths at the Cheesecake factory was $133.03

A drought is a long period of abnormally low precipitation. Suppose a drought occurred in Yellowstone National Park from 1916 to 1917. Predict how a graph line would appear for this time period. Explain your prediction in terms of the effect on resource availability.
Answer:
A drought is a long period of abnormally low precipitation. Suppose a drought occurred in Yellowstone National Park from 1916 to 1917. Predict how a graph line would appear for this time period. Explain your prediction in terms of the effect on resource availability.
Explanation: The graph line would have a downward trend because the amount of bison would start to decrease. Droughts heavily impact grassland ecosystems. A drought would increase the risk of a wildfire starting causing the bison to lose their habitat. The drought would also result in reduced plant growth. Therefore the bison would die off either because they were impacted by a wildfire, because they don’t have grass to eat etc.

The effect that most likely occurs due to a hurricane is:
Option A. Damaged houses due to flooding.
The effect can be explained as:
The hurricane can cause storm surge in which the levels of the sea rises than normal and causes high tides that can lead to floods.The heavy rainfalls and typhoons caused by hurricanes lead to floods that damage homes.Hail and forest fires due to lightning strikes are not caused by hurricanes and hence are not affected by the hurricane.Therefore, hurricane causes flooding.

how does the human body return carbon to the atmosphere in the carbon cycle?
Answer:
There is a constant exchange of carbon from the abiotic and biotic environmental elements to the atmosphere. The breakdown of glucose is known as cellular respiration, and creates the byproduct carbon dioxide. This exhaled carbon dioxide is the method by which humans return carbon to the carbon cycle.
Explanation:
can anybody describe why it rains? Include the words that scientists use
when talking about how water changes from liquid to gas and back to liquid
again
In a cloud, water droplets condense onto one another, causing the droplets to get bigger and increase. When these droplets heavy enough, they fall to Earth as rain droplets. That is when we feel and see the rain. Water vapor turns into clouds when it cools and then condenses,or when it turns back into liquid water or ice.

On the internet, read about the Clean Air Act of 1990:
a. Summarize what it says.
b. How should it help with the problem of acid rain?
c. How successful has it been in reducing the harmful chemicals from the burning of fossil fuels that cause acid rain?
d. What can you do personally to help alleviate the problem of acid rain?
3. Find two examples of actual ecological places that have been affected by acid rain. Tell their location and describe what happened.
Acid rain is formed when gases such as SOx and NOx are released by burning fossil fuels.
The clean air act has to do with the reduction of the gases that lead to acid rain such as SOx and NOx. The full implementation of the legislation ought to reduce the occurrence of acid rain.
However, since the introduction of the act in 1990, reduction in acid gas pollution has not reduced significantly since acid gases are still produced by the burning of fossil fuels.
To help alleviate the problem of acid rain, I must reduce my use of gasoline powered vehicles and embrace vehicles that depend on renewable energy sources and clean fuels such as hydrogen fuel.
