Part A would be 2 lines below the surface because since he is 2 lines above the surface (represented by +10 feet).
Part B would be -50 feet because he would be BELOW the surface (represented by "-", like -45).
Part C would be 20 because DeWayne would be at the tip of the seaweeds, -20 feet. Since each line is 5 feet, then he would have to swim 20 feet up to reach the surface.
Part D would be 0 feet. Since one line above the surface is 5, and one line below the surface is -5, subtracting or adding 5 would be 0.

Answer:
a: is false the base is an rectangle
b: is true because you multipluy the hight depth and length. that gives you 81

Answer:
Second well was deep below the surface.
Step-by-step explanation:
Given:
Depth of First well =
can be Rewritten as
Depth of First well =
Also Given:
The second well had more water, and was deeper than the first well.
can be Rewritten as
Hence We can say that;
Depth of second well is equal to plus Depth of First well.
framing in equation form we get;
Depth of second well =
Now the denominators are common so we can solve the numerators
now to solve the fractions we need to make the denominator common we will use L.C.M we get;
Depth of second well =
Now the denominators are common so we can solve the numerators.
Depth of second well =
Hence Second well was deep below the surface.
