Application of Adding Rational numbers.
A Scuba diver 75 feet below sea level. She then ascends 12.7 feet. What is the current depth of the scuba diver? (1 point)
If its not working make it negative
To find the current depth of the scuba diver, we need to add the depth at 75 feet below sea level with the ascent of 12.7 feet.
-75 + 12.7 = -62.3
Therefore, the current depth of the scuba diver is -62.3 feet.
A scuba diver is 75 feet below sea level. She then ascends 12.7 feet. What is the current depth of the scuba diver?(1 point)
feet
To find the current depth of the scuba diver, we need to subtract the ascent of 12.7 feet from the initial depth of 75 feet below sea level.
75 - 12.7 = 62.3
Therefore, the current depth of the scuba diver is 62.3 feet below sea level.
To find the current depth of the scuba diver, we need to add the depth below sea level with the distance she ascended.
Step 1: Convert the depth below sea level and the distance ascended into decimals if necessary.
The depth below sea level is already given in feet, so no conversion is needed. The distance ascended is 12.7 feet.
Step 2: Add the depth below sea level and the distance ascended.
75 feet + 12.7 feet = 87.7 feet
Therefore, the current depth of the scuba diver is 87.7 feet.
To find the current depth of the scuba diver, we need to add the distance she ascended (12.7 feet) to her initial depth (75 feet below sea level).
To do this, we can use the concept of adding rational numbers:
1. Start by writing down the initial depth of the scuba diver: -75 feet (since she is below sea level).
2. Add the distance she ascended: -75 + 12.7.
To add the numbers, we line up the decimal points:
-75.0
+ 12.7
________
?
3. Now, we can add the numbers. Start by adding the digits in the ones place, 0 and 7. The sum is 7. Write down 7 below the line, and carry over the 1 to the tenths place.
4. Add the digits in the tenths place, 5 and 2 (including the carried-over 1). The sum is 7. Write down 7 below the line.
5. The digit in the hundreds place remains 0, as we have no digits to add in that place.
After adding, we get the sum -62.3.
Therefore, the current depth of the scuba diver is -62.3 feet.
