tive to sea level ? 1. ( -105 meters) 2. ( -75meters) 3.( -35 meters) 4. ( 25 meters)
2 answers:
First condition of submarine=50 m below the sea=-50 m
It goes up 15 m, that means we must add up 15 m.
-50 m+15 m=
15 m-50 m=-35 m (35 m below the sea)
And, then goes down 40 m, so we subtract it with 40 m.
-35 m-40 m=-75 m (75 m below the sea)
So, the right answer is 2. (-75 meters)
Thank you.
Answer:
-75 meters
Step-by-step explanation:
First, subtract 15 from 50, since it is going up:
50 - 15
= 35
Then, add 40, since it is going back down:
35 + 40
= 75
So, the new position is -75 meters relative to sea level
