Q. A scientist was in a submarine,

feet below sea level, studying ocean life. Over the next ten minutes, she rose

feet. How many feet was she now below sea level?

\newline

Answer:

\square

feet

Identify Depth Information: Identify the initial depth and the change in depth. $\newline$ The scientist was initially $41.4$ feet below sea level. She then rose $33.6$ feet. To find the new depth, we need to subtract the change in depth from the initial depth. $\newline$ Initial depth = $41.4$ feet $\newline$ Change in depth = $33.6$ feet $\newline$ New depth = Initial depth $-$ Change in depth
Calculate New Depth: Perform the subtraction to find the new depth. $\newline$ New depth = $41.4$ feet - $33.6$ feet $\newline$ New depth = $7.8$ feet $\newline$ The scientist is now $7.8$ feet below sea level after rising $33.6$ feet.
