What is a value of the denominator that will make the number 12 / ? A whole number?

The maximum volume of the box in terms of the height h is (30 - h/2)^2 x h, and the height that allows us to have the maximum volume is 40 inches

To answer your question, let's first understand that the volume of a box is given by the formula V = L x W x H, where L is the length, W is the width and H is the height. Since we are assuming the height is fixed, we can rewrite this formula as V = L x W x h.

Now, we know that the length plus width plus height of the box cannot exceed 60 inches. Therefore, we have the equation L + W + h = 60, which we can solve for L or W in terms of h. Let's solve for L: L = 60 - W - h.

Substituting this value of L into the formula for volume, we get V = (60 - W - h) x W x h. We can simplify this equation by expanding the brackets and collecting like terms to get V = -W^2h + 60Wh - h^2.

To find the maximum volume, we need to find the value of W that maximizes this equation. We can do this by differentiating the equation with respect to W and setting the derivative equal to zero. After some calculations, we get W = 30 - h/2.

Substituting this value of W back into the equation for volume, we get V = (30 - h/2)^2 x h. To find the height that gives us the maximum volume, we can differentiate this equation with respect to h and set the derivative equal to zero. After some calculations, we get h = 40 inches.

Therefore, the maximum volume of the box in terms of the height h is (30 - h/2)^2 x h, and the height that allows us to have the maximum volume is 40 inches.

The length of the unknown sides of the triangles are as follows:

CD = 10√2

AC = 10√2

BC =  10

AB = 10

Since, Triangle ACD

ΔACD is a right angle triangle.

Therefore, Pythagoras theorem can be used to find the sides of the triangle.

c² = a² + b²

where

c = hypotenuse side = AD = 20

a and b are the other 2 legs

lets use trigonometric ratio to find CD,

cos 45 = adjacent / hypotenuse

cos 45 = CD / 20

CD = 1 / √2 × 20

CD = 20 / √2 = 20√2 / 2 = 10√2

Hence,

20² - (10√2)² = AC²

400 - 100(2)  = AC²

AC² = 200

AC = √200 = 10√2

Triangle ABC

ΔABC is a right angle triangle too. Therefore,

AB² + BC² = AC²

Using trigonometric ratio,

cos 45 = BC / 10√2

BC = 10√2 × cos 45

BC = 10√2 × 1 / √2

BC = 10√2 / √2 =  10

Hence,

(10√2)² - 10² = AB²

The measure of the third angle is approximately 18.93 degrees.

To find the measure of the third angle of a triangle, we need to use the fact that the sum of the three angles in any triangle is always equal to 180 degrees.

First, we need to convert the given angles from degrees, minutes, and seconds into decimal degrees. To do this, we can use the following formulas:

decimal degrees = degrees + (minutes/60) + (seconds/3600)

For the first angle, 41° 31' 29", we have:

decimal degrees = 41 + (31/60) + (29/3600)

= 41.5247

For the second angle, 119° 32' 59", we have:

decimal degrees = 119 + (32/60) + (59/3600)

= 119.5497

Now we can find the measure of the third angle by subtracting the sum of the first two angles from 180 degrees:

third angle = 180 - (41.5247 + 119.5497)

= 18.9256 degrees

Therefore, the measure of the third angle is approximately 18.93 degrees.

It takes Steve 12 hours to process the research paper alone.

Let's use the terms "research," "hours," and "paper" in our answer.

Step 1: Represent the rate of work for Alan and Steve using variables.
Let A = Alan's rate of work (paper per hour) and S = Steve's rate of work (paper per hour).

Step 2: Set up equations based on the given information.
Alan can complete the research paper in 6 hours, so his rate is 1/6 paper per hour: A = 1/6.
Together, Alan and Steve can complete the paper in 4 hours, so their combined rate is 1/4 paper per hour: A + S = 1/4.

Step 3: Substitute the known value of A (Alan's rate) into the equation and solve for S (Steve's rate).
(1/6) + S = 1/4

Step 4: Solve for S.
To do this, first find a common denominator for the fractions, which is 12. Then, rewrite the equation with equivalent fractions:
(2/12) + S = (3/12)

Now, subtract 2/12 from both sides of the equation:
S = (3/12) - (2/12)

This simplifies to:
S = 1/12

Step 5: Determine how long it takes Steve to complete the research paper alone.
