Answer:

  • 200 more years
  • 15 years

Explanation:

Tantalum is a metal used to manufacture electronics such as cell phones, computers and digital cameras. The problem with tantalum is that it is found in coltan ore, which is mostly mined in Africa. The African country with the largest tantalum exports is Congo, a country devastated by continuous civil wars. Millions of people have been killed in these civil wars and the warlords control coltan mines.

Cost of Goods Sold Allyson Ashley makes jet skis. During the year, Allyson manufactured 68,500 jet skis. Finished goods inventor
Nuetrik [128]

Answer:

Units sold= 63,465 units

Cost of goods sold= $114,237,000

Explanation:

Giving the following information:

Allyson manufactured 68,500 jet skis. Finished goods inventory had the following units:

January 1: 14,385

December 31: 19,420

First, we need to calculate the number of units sold:

Units sold= production of the period + beginning inventory - ending inventory

Units sold= 68,500 + 14,385 - 19,420= 63,465 units

Cost of goods sold= 63,465*1,800= $114,237,000

Suppose you have a machine which executes a program consisting of 60% floating point multiply, 20% floating point divide, and th
Aliun [14]

Answer:

Given that Program instructions consists of:

  • 60% floating point multiply
  • 20% floating point divide
  • 20% other instructions

Amdahl's law states that:

Execution time affected by improvement = (Execution time after improvement/ Amount of improvement) + (Execution time unaffected)

Assuming initially that floating point multiply, divide and other instructions have same clocks per instruction (CPI).

Part (a)

New execution time after improvement with multiply = (60) / 8 + (20 + 20) = 47.5

New execution time after improvement with Divide = (20) / 3 + (60 + 20) = 86.67

New system should be 4x faster which means new execution time should be below = 100/ 4 = 25.

Therefore, Management's goal can NOT be achieved by making the improvement with multiply or divide alone.

Part (b)

New execution time after improvement with multiply and divide = (60 / 8) + (20 / 3) + 20 = 34.17

Speed up = execution time of original machine / Execution time of new machine = (100 / 34.17) = 2.93

Therefore, new machine is 2.93 times faster than original machine.

Bonita and Miller Manufacturing is trying to determine the equivalent units for conversion costs with 11400 units of ending work
ratelena [41]

Answer:

The equivalent units for conversion cost are 28080.

Explanation:

Firstly, we need to find our how much units are being sold

Units Sold= physical units - ending units

Units sold= 31500 - 11400 = 20100

Then we need to add units sold with percentage completion of ending units in order to find out equivalent units for conversion cost

Formula:

Equivalent units for conv. cost= units sold + (%completion of ending units)

Equivalent units for conv. cost= 20100 + ( 70% ×11400)

Equivalent units for conv. cost= 20100 + 7980

Equivalent units for conv. cost= 28080
