Final answer:
Approximately 23,000 people visited the zoo today. This was determined by rounding the number 23,259 down to the nearest thousand since the hundreds digit is less than 5.
Step-by-step explanation:
The question asks about rounding the number of people who visited the zoo to a simpler approximation. To find an approximate answer, we can round the number 23,259 to the nearest thousand. Rounding to the nearest thousand involves looking at the hundreds digit, which is a 2 in this case. Since the hundreds digit is less than 5, we round down. Therefore, the rounded figure is 23,000. So, about 23,000 people visited the zoo today.
To address the reference information given, here are some examples:
- Using scientific notation to represent the number of adults who believe aliens have visited Earth: 222,000,000 adults * 36% = 79,920,000, which can be written as 7.992 x 107 in scientific notation.
- If a country's population is 20 million and we're calculating expected growth or decline for next year, we would need additional information such as birth and death rates.
- In a university cafeteria, if 889,875 burgers are eaten and 997 are veggie-burgers, the fraction of veggie-burgers is 997/889,875. To find the percent, divide 997 by 889,875 and then multiply by 100.
