The Amonzon River releases 5.5 x 10^7 gallons of water into the Atlantic Ocean every second. There are about 3.2 x 10 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.
To find the number of gallons released into the ocean in one year, we need to multiply the number of gallons released per second by the number of seconds in a year.
The number of gallons released per second is given as 5.5 x 10^7 gallons/second.
The number of seconds in a year is given as 3.2 x 10^7 seconds/year.
We can multiply these two values to find the total number of gallons released in one year:
(5.5 x 10^7 gallons/second) * (3.2 x 10^7 seconds/year) = 1.76 x 10^15 gallons/year.
Therefore, approximately 1.76 x 10^15 gallons are released into the ocean in one year.
U sure?
Apologies for the mistake in my previous response. Let's correct it:
The number of gallons released per second is given as 5.5 x 10^7 gallons/second.
The number of seconds in a year is given as 3.2 x 10^7 seconds/year.
We can multiply these two values to find the total number of gallons released in one year:
(5.5 x 10^7 gallons/second) * (3.2 x 10^7 seconds/year) = 1.76 x 10^15 gallons/year.
Therefore, approximately 1.76 x 10^15 gallons are released into the ocean in one year.
My previous response was correct, I apologize for any confusion.
35 ÷ 5 x 7 -2^3
To simplify the expression 35 ÷ 5 x 7 - 2^3, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
Step 1: Simplify exponents
2^3 = 2 * 2 * 2 = 8
Step 2: Perform division and multiplication from left to right
35 ÷ 5 x 7 = 7 x 7 = 49
Step 3: Perform subtraction
49 - 8 = 41
Therefore, the simplified expression is 41.
