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.
To find the number of gallons released into the ocean in one year, we can multiply the number of gallons released per second by the number of seconds in a year.
First, let's multiply the number of gallons released per second by the number of seconds in a year:
5.5 * 10^7 gallons/second * 3.2 * 10^7 seconds/year = 17.6 * 10^14 gallons/year
Next, let's express the result in scientific notation and round to the appropriate number of significant digits:
1.76 * 10^15 gallons/year
Therefore, the number of gallons released into the ocean in one year is 1.76 * 10^15 gallons.
what is 1.76 * 10^15?
1.76 * 10^15 is equal to 1,760,000,000,000,000 or 1.76 quadrillion.
Calculate the value of the expression 35(Divided by) 5 * 7-2^3
-7
-1
7
41
To calculate the value of the expression 35 ÷ 5 * 7 - 2^3, we follow the order of operations:
First, we calculate 2^3, which equals 8.
Then, we perform the division 35 ÷ 5, which equals 7.
Next, we multiply 7 by 7, which equals 49.
Finally, we subtract 8 from 49, which equals 41.
Therefore, the value of the expression 35 ÷ 5 * 7 - 2^3 is equal to 41.
Calculate the value of the expression ²√(110-137)+4(-5)²
97
103
37
To calculate the value of the expression ²√(110-137)+4(-5)², we follow the order of operations:
First, we calculate the value inside the square root, which is 110-137 = -27.
Next, we take the square root of -27, which is √(-27). However, the square root of a negative number is not a real number, so the expression is undefined.
Therefore, the value of the expression ²√(110-137)+4(-5)² is undefined.
wich answer is right?
I apologize for the incorrect response. Let's reevaluate the expression.
The expression is ²√(110-137) + 4(-5)².
We first calculate the value inside the square root, which is 110 - 137 = -27.
According to the order of operations, we evaluate exponentiation before evaluating the square root. Thus, we calculate (-5)², which is 25.
Now, the expression becomes ²√(-27) + 4(25).
We cannot take the square root of a negative number. Therefore, this expression is undefined.
I apologize for the mistake in my previous response. The correct answer is that the value of the expression is undefined.
