To find the number of times higher the number of library visits before the examination day is compared to the visits in an 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
Times higher = (Number of visits before examination day) / (Number of visits in an average week)
= (2×10^3) / (5×10^2)
= (2/5) × (10^3/10^2)
= 0.4 × 10
= 4
Therefore, the number of library visits before examination day is 4 times higher than the number of visits in an average week.
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)

It takes 10 years for a $100 monthly bank deposit to amount to $15,528.23 when invested at 5% interest compounded monthly. Round to the nearest place value, then express the amount $15,528.23 in the form of a×10^n where a is single digit.(1 point)
To find the amount in the form of a×10^n, we need to round the given amount, $15,528.23, to the nearest place value.
Rounded amount = $15,528
Since we are rounding the amount to the nearest place value, we can express it in the form of a×10^n as follows:
$15,528 = 1.5528 × 10^4
Therefore, the amount $15,528.23 can be expressed in the form of a×10^n as 1.5528 × 10^4.
Rounded amount = $15,528
Since we are rounding the amount to the nearest place value, we can express it in the form of a×10^n as follows:
$15,528 = 1.5528 × 10^4
Therefore, the amount $15,528.23 can be expressed in the form of a×10^n as 1.5528 × 10^4.

To express the amount $15,528.23 in the form of a×10^n where a is a single digit, we need to round the given amount to the nearest place value.
Rounded amount = $15,528
To express this rounded amount in the desired form, we can rewrite $15,528 as 1.5528 × 10^4. However, this is not in the form of a×10^n where a is a single digit.
To convert it to the desired form, we can divide both sides of the equation by 10^4:
⇒ (1.5528 × 10^4) / (10^4) = 1.5528
Therefore, the amount $15,528.23 can be expressed in the form of a×10^n as 1.5528 × 10^4, where a = 1 and n = 4.
