Diving. An underwater exploration team is swimming at a depth of -20 feet.
Then they drive to an underwater cave that is at 7 times this depth.
What is the depth of the underwater cave?
dont; know what to do??
-20(7)=?
think it is -140 idk
To find the depth of the underwater cave, we need to find 7 times -20 feet.
First, let's determine the value of -20 feet multiplied by 7. Multiplying a negative number by a positive number will result in a negative number.
-20 feet multiplied by 7 = -140 feet
Therefore, the depth of the underwater cave is -140 feet. Since we're dealing with depths, the negative sign indicates that the cave is below sea level.
