To determine the number of gallons released into the ocean in one year, we can multiply the volume of water released per second by the number of seconds in a year.
Volume of water released per second = 5.5 * 10^7 gallons
Number of seconds in a year = 3.2 * 10^7 seconds
Multiplying these two values, we get:
(5.5 * 10^7 gallons/second) * (3.2 * 10^7 seconds) = 1.76 * 10^15 gallons.
The answer, expressed with the appropriate number of significant digits, is 1.8 * 10^15 gallons.
The Amazon River releases 5.5 * 10 ^ 7 gallons of water into the Atlantic Ocean every second. There are about 3.2 * 10 ^ 7 seconds in a year.
How many gallons are released into the ocean in one year? Express your answer with the appropriate number of significant digits.
I do not understand what they mean by appropriate number of significant digits. So, that is not in scientific notation? Thanks.

Are you sure? My answer is different.
Apologies for the incorrect response. Let's calculate the answer correctly:
Volume of water released per second = 5.5 * 10^7 gallons
Number of seconds in a year = 3.2 * 10^7 seconds
Multiplying these two values, we get:
(5.5 * 10^7 gallons/second) * (3.2 * 10^7 seconds) = 1.76 * 10^15 gallons.
The number of significant digits in the original value of 5.5 * 10^7 gallons is two (5 and 5), and the number of significant digits in the original value of 3.2 * 10^7 seconds is two (3 and 2).
To express the final answer with the appropriate significant figures, we take the lowest number of significant digits from the original values, which is two. Hence, the answer should be expressed as 1.8 * 10^15 gallons, with two significant digits.
