Answer:

The answer to Question A is well explained in the attachment

B) The increase in the Z value with the increase in unit in the particular resource is said to be shadow source of a resource.

It can be resolved with the help of an optimal solution

Step-by-step explanation:

Consider the following problem.

Maximize Z = x1 ? 7x2 + 3x3

subject to

2x1 + x2 ? x3 ? 4

4x1 ? 3x2 ? 2

?3x1 + 2x2 + x3 ? 3

x1, x2, x3 ? 0

(a) (points: 6) Work through the simplex method step by step to solve the problem.

(b) (points: 4.5) Identify the shadow prices for the three resources and describe their significance.

The answer to A is explained in the attachment

b) The increase in the Z value with the increase in unit in the particular resource is said to be shadow source of a resource.

It can be resolved with the help of an optimal solution

Min-Jee is planting two rectangular flower beds. One bed is 2.78 feet by 4.81 feet, and the other bed is 2.78 feet by 5.61 feet.

Answer: $(2.78+4.81)(2.78+5.61)$

Step-by-step explanation:

<h3> The complete exercise is attached.</h3><h3></h3>

The area of a rectangle can be calculated with this formula:

$A=lw$

Where "l" is the lenght and "w" is the width.

Then, you can notice that it can be obtained by multiplying the dimensions of the rectangle.

Knowing this, you can determine that the total area of the two flowers bed can be obtained by adding the products of their dimensions.

Since one of the rectangular flower bed is 2.78 feet by 4.81 feet and the other bed 2.78 feet by 5.61 feet, you can write the following expression to find the total area (in square feet)of the two beds:

$2.78*4.81 +2.78*5.61$

If you factor out 2.78:

$2.78(4.81 +5.61)$ or $(4.81 +5.61)2.78$

Therefore, the expression that does not represent the total area in square feet of the two beds, is:

$(2.78+4.81)(2.78+5.61)$

Dahasolnce [82]

Answer:

The first two pieces are 5' 5" long; the last piece is 5' 2" long.

Step-by-step explanation:

If x is the length of one of the longer pieces, then the shorter one (in inches) is x-3. The total length of the three pieces is ...

x + x + (x-3) = 192

3x = 195 . . . . . . . . . add 3

x = 65 . . . . . . . . . . inches

65 inches = 5 ft 5 inches

The first two pieces are each 5' 5" long; the remaining piece is 5' 2" long.
