Ageologist found two underground wells that contained large deposits of water. the first well was 46 2/3 meters below the surface. the second well had more water, and was 77 5/6 meters deeper than the first well. how deep below the surface was the second well?

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.

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
