Answer:
Parallelogram = 2 pairs of parallel sides and opposite angles are equal
Triangle BEA and triangle DFC are equivalent by side angle side
Therefore, angle DCF is equivalent to angle BAE
Angles FEB and DFE are right angles due to them being supplementary angles with angles BEA and DFC, respectively.
This means triangles BEC and DFA are equivalent.
This means angles FCB and EAD are equivalent, which means angles BCD and DAB are equivalent.
This also means angles ABC and ADC are equivalent.
Opposite angles equivalent = parallelogram
Answer: 227 pounds.
Step-by-step explanation:
By definition, the volume of a rectangular prism can be calculated with the following formula:

Where "w" is the width of the rectangular prism, "l" is the length and "h" is the height of the rectangular prism.
In this case you know that:

Substituting values into the formula, you get that the volume of the shipping container is:

You know that it was completely filled with contents that weigh 0.56 pound per cubic foot, approximately. Then, its density is:

Since:

Where "m" is mass and "V" is volume, you can susbstitute values and solve for "m":

Answer:
Suppose that you have a square of side length x, the area of this square will be:
A = x^2.
Now, by dynamics, we know that the position of an object that is falling down from a height H, can be written as:
H(t) = (-g/2)*t^2 + H.
We can see a pattern, x^2 is used in both.
Now, profit can be also modeled with quadratic equations, where our objective is to find the maximum of the quadratic (so we can have the maximum profit)
Then the parent function that is useful for gravity, calculating area and profit is the quadratic function:
f(x) = x^2
Just add them up 15+5+3+8
