A Dolphin is 30 feet below the surface of the water. She rised 23 feet, sinks 17 feet, and finally rises another 27 feet. If there are no other changes, the dolphin is
-30+23= -7
-7-17= -24
-24+27= 3
is it above water or below water
30 + 23 + 27 - 17 = ?
Apparently it's a flying fish... 3 feet above water. Wtf... ugh stupid flying fishs
it is above the water
It is 3 feet above the water. If you wrote out a number line and did the math there, you would've easily figured it out.
30+ 23+27-17= 80-17= 63
63
-30+23-17+27=3
To determine the final position of the dolphin, we need to track its cumulative change in depth. Let's break down each movement step by step:
1. The dolphin initially starts 30 feet below the surface.
2. It rises 23 feet, so its depth changes to 30 - 23 = 7 feet below the surface.
3. It sinks 17 feet, so its depth changes to 7 + 17 = 24 feet below the surface.
4. Finally, it rises another 27 feet, so its depth changes to 24 - 27 = -3 feet below the surface.
The negative depth value of -3 feet means that the dolphin is 3 feet above the water surface. Therefore, the dolphin is 3 feet above the water.
