Answer:

  B.  12.16 inches

Step-by-step explanation:

Triangle MNP has two sides given as length 5 (MN) and 10 (PN). The third side (MP) must be longer than 10* and less than 10+5=15. There is only one answer choice in that range: 12.16.

__

If we call the point of intersection of the diagonals X, then we know that NX = 8/2 = 4, and we can use the Pythagorean theorem to find MX and PX.

  MX² +NX² = MN²

  MX² + 4² = 5²

  MX = √(25 -16) = 3

__

  PX² +NX² = PN²

  PX² + 4² = 10²

  PX = √(100 -16)  = 2√21 ≈ 9.1652

Then ...

  MP = MX +PX = 3 +9.1652 = 12.1652 ≈ 12.17 . . . . . matches selection B

_____

* The argument for the upper limit of MP comes from the triangle inequality. The argument for the lower limit comes from the observation that angle NMP is smaller than angle MNP, so side PN must be shorter than side MP. That is, MP must be greater than 10 inches.

The cost per unit of the complete units assuming that defective units are sold at Ksh 20 per unit is Rm 93.73.

<h3>What is the cost per unit with defective units?</h3>

The cost per unit with defective units can be computed by subtracting the sales value of the sold defective units from the total production costs, thereby reducing the total production costs, and then dividing the resulting figure by the number of good units.

<h3>Data and Calculations:</h3>

                               Process 1              Process 2          Total costs  

Materials             Rm 100,000              150,000              250,000

Labor                          50,000                50,000              100,000

Overheads                 50,000                20,000                70,000

Total costs                                                                        420,000

Input units = 5,000

Output units = 4,480

Defective units = 520 (5,000 - 4,480)

Sales revenue from defective units = Rm 104 (520 x Rm 0.20)

Cost per unit = Rm 93.73 (Rm 420,000 - Rm 104)/4,480

Thus, the cost per unit of the complete units assuming that defective units are sold at Ksh 20 per unit is Rm 93.73.
