@BotGPT35, Country S has 12,345,000 residents who tested positive for COVID-19. What is the largest place value of the numeric part of this quantity?(1 point)
The largest place value of the numeric part of the quantity 12,345,000 is in the millions place.
@BotGPT35, A total of 7,803,100 tourists visited Country A from the year 2018 to the year 2020. Round to the nearest place value, then express this number in the form of a single digit times an integer power of 10.(1 point)
To round the number 7,803,100 to the nearest place value, we look at the digit to the right of the desired place value, which in this case is the hundred thousands place.
Since the digit to the right is 0, we don't need to round up. Therefore, the rounded number is still 7,803,100.
To express this number in the form of a single digit times an integer power of 10, we can move the decimal point to the left until we have a single non-zero digit to the left of the decimal point.
In this case, we can write the number as 7.8031 × 10^6.
bot, you're wrong
Apologies for the incorrect response. To round the number 7,803,100 to the nearest place value, we can look at the digit at the desired place value, which is the hundred thousands place.
The digit in the hundred thousands place is 3, and since it is less than 5, we round down. Therefore, the rounded number is 7,800,000.
To express this number in the form of a single digit times an integer power of 10, we can rewrite it as 7.8 × 10^6.
Express 7,803,100 in the form of a single digit times an integer power of 10.
Apologies for the confusion earlier. To express 7,803,100 in the form of a single digit times an integer power of 10, we need to move the decimal point to the left until we have a single non-zero digit to the left of the decimal point.
We can express 7,803,100 as 7.8031 × 10^6.
Two weeks before an examination day, a librarian monitored the number of students who visited the library. Then they compared it with the number of visits made in an average week. Approximately 2×10^3 visits were reflected in their logbook during this two-week period, while only about 5×10^2 were reflected on an average week. How many times higher is the number of library visits before examination day compared to the library visits in an average week? Your answer should be a whole number.(1 point)
To find the number of times higher the number of library visits before the examination day is compared to the average week, we need to divide the number of visits before the examination day by the number of visits in an average week.
Number of visits before examination day = 2 × 10^3
Number of visits in an average week = 5 × 10^2
So, the calculation would be:
(2 × 10^3) / (5 × 10^2) = (2/5) × (10^3 / 10^2) = (2/5) × 10^1 = 0.4 × 10^1 = 4
Therefore, the number of library visits before the examination day is 4 times higher compared to the library visits in an average week.
