Q. A scientist uses a submarine to study ocean life.\newline- She begins at sea level, which is an elevation of o feet.\newline- She travels down 8383.44 feet.\newline- She then travels directly up 1515.66 feet.\newline- Next, she descends a second time, 2727.66 feet.\newlineHow many feet must she now rise to get back to sea level?\newlineAnswer: □\squarefeet
  1. Calculate total descent: Calculate the total descent by adding the two descents.\newlineFirst descent: 83.483.4 feet\newlineSecond descent: 27.627.6 feet\newlineTotal descent = 83.483.4 feet + 27.627.6 feet
  2. Perform calculation: Perform the calculation for the total descent.\newlineTotal descent = 83.483.4 feet + 27.627.6 feet = 111111 feet
  3. Calculate total ascent: Calculate the total ascent by adding any ascents the scientist made.\newlineTotal ascent so far: 15.615.6 feet
  4. Determine net descent: Determine the net descent by subtracting the total ascent from the total descent.\newlineNet descent = Total descent - Total ascent\newlineNet descent = 111111 feet - 15.615.6 feet
  5. Perform calculation: Perform the calculation for the net descent. Net descent = 111 feet−15.6 feet=95.4 feet111 \text{ feet} - 15.6 \text{ feet} = 95.4 \text{ feet}
  6. Find net descent: The net descent is the amount the scientist must rise to get back to sea level.\newlineAnswer = 95.495.4 feet
