Solve and connect the correct model to the algorithm: A submarine dives 1,200 feet below sea level. It then dives down 943 feet. What is its current depth?(1 point)
Responses
The correct model to solve this problem is subtraction.
Algorithm: Current Depth = Initial Depth - Distance Dived
Let's apply this algorithm to the problem:
Initial Depth: 1,200 feet
Distance Dived: 943 feet
Current Depth = 1,200 - 943
Current Depth = 257 feet
Therefore, the submarine's current depth is 257 feet.
What model matches the situation: Maxwell’s bank account is currently in the negative by $47. He spent another $29 at the store. What is his current balance?(1 point)
The correct model to solve this problem is addition.
Algorithm: Current Balance = Initial Balance + Money Spent (if in the negative, it is considered as spent)
Let's apply this algorithm to the problem:
Initial Balance: -47 dollars
Money Spent: 29 dollars
Current Balance = -47 + 29
Current Balance = -18 dollars
Therefore, Maxwell's current balance is -18 dollars, meaning he still owes $18.
To find the current depth of the submarine, we need to add the two diving distances together.
1,200 feet (initial depth) + 943 feet (second dive) = 2,143 feet
Therefore, the submarine's current depth is 2,143 feet below sea level.
