Step-by-step explanation:

first take an inequality .remove the inequality sign and then draw its graph .

now put the value x=y=0 in the inequality equation to check if its within the graph .if it satisfies the eqn then shade that part of the line which has the origin in it .similarly do for other inequalities.

you will/may get a polygon .it may be bounded or not. now by fundamental theory of lpp, obtain the terminal points

and get the values of x and y. calculate the respective value of fx and find the maximum and minimum of them .the answer will be the respective x and y values.

you can comment me to do a sum of other questions

A cube-shaped aquarium has edges that are 3 feet long and is filled with water that has a density of 62 lbs/ft3 Should the aquar

Sunny_sXe [5.5K]

Given:

There are given the edge of the cube-shaped aquarium has 3 feet.

Explanation:

To find the value, we need to use the volume of the cube formula:

So,

From the formula of volume:

$V=a^3$

Where

a represents the value of edge.

So,

Put the value of edge into the above formula:

Then,

$\begin{gathered} V=a^3 \\ V=3^3 \\ V=27cube\text{ feet} \end{gathered}$

Now,

The water has a density of 62 pounds per cube foot.

According to the question:

If the weight of 1 cubic foot of water is 62 pounds, then the weight of 27 cube feet water is:

$62\times27=1674pound$

Final answer:

Hence, the water weight of the full aquarium is 1674 pounds, and the table only susupports00 pounds. So the table cannot hold the aquarium.

And,

No, the density of water would not change.
