A submarine was 144 feet below sea level. A shark was hovering at a constant depth above the submarine. The submarine’s depth wa

Lelu [443]

Answer:

$-72$ feet : Shark is 72 feet below sea level.

Step-by-step explanation:

Let x represent depth of the shark.

We have been given that the submarine’s depth was twice the depth of the shark. This means that depth of submarine would be $2x$ .

We have been given that a submarine was 144 feet below sea level, so submarine's elevation would be $-144\text{ ft}$ .We can represent this information in an equation as:

$2x=-144$

To find shark's position, we need to solve for x.

$\frac{2x}{2}=\frac{-144}{2}$

$x=-72$

Therefore, $-72$ feet represents shark's elevation, which represents that shark is 72 feet below sea level.

Jalen is painting her great room including the ceiling but not the floor. The room measures 20 ft long, 30 wide and 9 ft tall.

Luden [163]

4 cans of paint

$\sf ---> \ \ {\boxed {\boxed {\frac{area \ of \ room - area \ of \ floor}{area \ the \ paint \ covers} }}}$

$\hookrightarrow \sf {\dfrac{2(wl+hl+hw)- (lw)}{400}}$

$\hookrightarrow \sf {\dfrac{2((30)(20)+(9)(20)+(9)(30))-(20*30)}{400}$

$\hookrightarrow \sf {\dfrac{1500}{400}$

$\hookrightarrow \rm {\sf {3.75}}$

→ She should buy max 4 cans as she cannot buy 3.75 cans.

Here l refers to length, w refers to width, h refers to height.
