Answer:

Option A.

Step-by-step explanation:

Let x be the number of trays of corn muffins and y be the number of trays of bran muffins.

He makes $3.00 profit per tray of corn muffins and $2.00 profit per tray of bran muffins.

Objective function: Z=3x+2y

According to the the given information:

                      Corn muffins     Bran muffins                Total    

Milk                         4                        2                            16

Wheat flour            3                         3                            15

Subject to the constraints are

4x+2y\leq 16

3x+3y\leq 15

x\geq 0,y\geq 0

Draw the graph of above qualities as shown below.

The vertices of feasible region are (0,0), (0,5), (3,2) and (4,0).

Point         Z=3x+2y

(0,0)                0

(0,5)                10

(3,2)                13

(4,0)                12

The profit is maximum at x=3 and y=2.

3 trays of corn muffins and 2 trays of bran muffins.

Therefore, the correct option is A.

Answer:

<h2>X = 59°</h2>

Step-by-step explanation:

To find Angle X we use sine

sin∅ = opposite/ hypotenuse

From the question

WY is the opposite

WX is the hypotenuse

So we have

sin X = WY/ WX

sin X = 6/7

X = sin-¹ 6/7

X = 58.99

X = 59° to the nearest tenth

Hope this helps you
