When the surrounding flaps are folded up, the base of the box will have dimensions 11-2x by 16-2x, and the box will have a height of x. So the box has volume, as a function of x,

V(x)=(11-2x)(16-2x)x=176x-54x^2+4x^3

I don't know what technology is available to you, but we can determine an exact value for x that maximizes the volume by using calculus.

Differentiating V with respect to x gives

\dfrac{\mathrm dV}{\mathrm dx}=176-108x+12x^2

and setting this equal to 0 gives two critical points at

x=\dfrac{27\pm\sqrt{201}}6\implies x\approx2.1\text{ or }x\approx6.9

For the larger critical point we would get a negative volume, so we ignore that one. Then the largest volume would be about 168.5 cubic in.

I am climbing up a mountain that has a lake at the bottom. The lake is 100 feet deep. If I have climbed one third of the way up
Vitek1552 [10]

Answer: 760 feet

Step-by-step explanation:

So, 220 feet is 1/3 of the mountain.

Now, multiply 220 x 3 = 660.

The top of the mountain is 660 feet.

The bottom of the lake is -100 feet.

Now just simply add 100 + 660 = 760

So, the total elevation change is 760 feet.

In a parallelogram, one angle is 9 times the size of another. Find the measures of the angles.
Pavlova-9 [17]
In a parallelogram, opposite angles are congruent. However, the same thing cannot be said for the other.

You can label one pair of opposite angles with x and the other 9x. 

You also know that each quadrilateral has interior angles that add up to 360 so you can create the equation of
9x+9x+x+x=360
which can be simplified into 

20x=360

x=18 

Now, you know the angle measures of one pair of opposite angles. to find the other you plug in 18 to our other equation and multiply 9 to get 162. 

The angles of the parallelogram is 18,18, 162 and 162. 

Note: you can check if this is right if all the angles add up to 360.
