1. You want to deliver an article with the most impact and easy reading to the readers; you decide that you need to present the data as percentages. For each of the data statements, though, none of them have percent’s. Convert each statement’s data into a percentage. Show your work below. Then, state which topic has the highest percent and which topic has the lowest percent.
In 2011, the total Municipal Solid Waste generated was 250 million tons; only 87 million tons were recovered for recycling.
Of the world’s estimated 7,100,000,000 people in 2012, the United States is the third most populated country with an estimated 313,850,000 people.
In 2009, over 3/10 of the 306.77 million people in the US were considered obese.
In 2009, the United States had installed 1,650 megawatts worth of solar energy compared to the world’s 20,146 megawatts total solar energy installed. This is the fourth highest amount of solar energy installed, trailing behind Germany, Spain, and Japan.
87 / 250 = 0.348 = 35%
314 / 7100 = 0.044 = 4%
3/10 = 0.3 = 30%
I'll be glad to check your answer for the last problem.
20146/1650=12.21%
To convert the data statements into percentages, we need to follow these steps:
1. Determine the percentage by calculating the ratio of the given value to the total value.
2. Multiply the ratio by 100 to get the percentage.
3. Round the percentage to the desired number of decimal places.
Let's proceed with each statement:
1. In 2011, the total Municipal Solid Waste generated was 250 million tons; only 87 million tons were recovered for recycling.
To find the percentage of waste recovered for recycling:
- Divide 87 million tons (recovered waste) by 250 million tons (total waste).
- Multiply the result by 100 and round to the nearest whole number.
- The percentage of waste recovered for recycling is approximately 35%.
2. Of the world’s estimated 7,100,000,000 people in 2012, the United States is the third most populated country with an estimated 313,850,000 people.
To find the percentage of the United States' population:
- Divide 313,850,000 (United States' population) by 7,100,000,000 (world's population).
- Multiply the result by 100 and round to the nearest whole number.
- The percentage of the United States' population is approximately 4%.
3. In 2009, over 3/10 of the 306.77 million people in the US were considered obese.
To find the percentage of obese people in the US:
- Calculate 3/10 of 306.77 million.
- Multiply the result by 100 and round to the nearest whole number.
- The percentage of obese people in the US is approximately 30%.
4. In 2009, the United States had installed 1,650 megawatts worth of solar energy compared to the world’s 20,146 megawatts total solar energy installed. This is the fourth highest amount of solar energy installed, trailing behind Germany, Spain, and Japan.
To find the percentage of the fourth highest amount of solar energy installed:
- Divide 1,650 megawatts (USA's installed solar energy) by 20,146 megawatts (total installed solar energy worldwide).
- Multiply the result by 100 and round to the nearest whole number.
- The United States contributed approximately 8% of the total solar energy installed.
Based on the calculated percentages, the statement with the highest percentage is "In 2009, the total Municipal Solid Waste generated was 250 million tons; only 87 million tons were recovered for recycling" with approximately 35%. The statement with the lowest percentage is "Of the world’s estimated 7,100,000,000 people in 2012, the United States is the third most populated country with an estimated 313,850,000 people" with approximately 4%.
