Answer:
The final depth of Melissa is 14 meters below the surface
Step-by-step explanation:
In this kind of problems, involving directions, etc, usually one position is the positive direction and the other position is the negative direction.
In our problem, we suppose that the surface is the positivo zero, above the surface is the positive position(positive depth) and below the surface is the negative directions(negative depth).
The problem states that Melissa is 29 meters below the surface. So, her initial position is 29 meters in the negative direction, so it is equal to -29.
Then, the problem states that Melissa rises upward 15 meters. Upward is the positive direction, so she moved to the positive direction. It means that we are going to do -29+15 = -14 meters.
It means that the final depth of Melissa is 14 meters below the surface

Answer:
54.872
Step-by-step explanation:
volume of a cube = s³
where s = side length
side length given here is 3.8
so volume = 3.8³ = 54.872
1st page: 580
2nd page: 576
in the 1st two pages: 580+576 = 1156
total word = 2000
total word = words written + words to write
2000 = 1156 + words to write
subtract 1156 from each side
2000-1156 = words to write
844 = words to write
Choice D
