How much time must elapse for the activity of a block of cheese containing 131i to drop to 1.0% of its initial value?

1 answer:

8 0

For the answer to the question above,An = Ao (1/2)^(time/halflife)

Let us assume that the "1.0" means 1%

... .01 = (1/2)^(time/8)
or ln(.01) = (time/8) ln(.5)
or time = 8 ln(.01)/ln(.5) or time = 53.150849518 days 
 This is not a business question but a math or physics by the way.I hope this helps

It is the year 2060, and you are talking (or perhaps telepathically communicating) with your grandchildren. "Grandparental Unit"

Makovka662 [10]

Answer:

The answer is: $20

Explanation:

To calculate how much money you will need in 2060 to buy an equivalent to $2 of today, we can use the current CPI and convert our money to base year dollars. Then we multiply our base year dollars by the CPI of 2060.

$2 / 2.4 CPI 2019 = $0.8333 base dollars

$0.8333 base dollars x 24 CPI 2060 = $20

This means that you will need $20 in 2060 to buy the same amount of goods that you bought with $2 in 2019.

Dartmouth Assessment Centre screens and trains employees for a computer assembly firm in Halifax. The progress of all trainees i

alexdok [17]

Answer:

Discourage Torri from continuing. Encourage Julie to continue.

Explanation:

The progress of all trainees is tracked. Those not showing good progress are moved to less demanding programs. This means that there is hope of still doing/getting a job, if they don't pass this test.

REQUIREMENT: By the 10th time doing the test, trainees must be able to complete the task in a maximum of 1 hour.

1st Trainee: Torri Olson-Alves

5 hours on Unit 4; 4 hours on Unit 8

Should Torri be encouraged to continue? NO.

There are 10 units or repetitions in all. If Torri spends 5 hours on Unit 4 and spends 4 hours on Unit 8, then Torri is slow or isn't making much progress. After 4 repetitions, her marginal product only increased by an hour. She most likely won't make it to 1 hour by the 10th repetition.

2nd Trainee: Julie Burgmeier

4 hours on Unit 3; 3 hours on Unit 6

Should Julie be encouraged to continue? YES.

Julie makes a progress of 1 hour after 3 repetitions. We can predict that after another 3 repetitions (on Unit 9) progress would be made again and by Unit 10, she would have met the required benchmark.

Based on the following information, calculate the cost of goods sold and ending inventory using FIFO, LIFO, and weighted average

Flauer [41]

Answer:

Cost of Sales :

FIFO = $ 6,030

LIFO = $6,840

Weighted Average = $6,354.60

Ending Inventory :

FIFO = $4,176

LIFO = $3,150

Weighted Average = $3,636.60

Explanation:

FIFO

This method assumes that the first inventory purchased will be the first to be sold

Cost of Goods Sold :

90 units × $11 = $990

150 units × $15 = $2,250

30 units × $18 = $540

Total = $ 6,030

Ending Inventory :

232 units × $18 = $4,176

LIFO

This method assumes that the last inventory purchased, will be the last to be sold

Cost of Sales :

240 units × $15 = $3,600

180 units × $18 = $3,240

Total = $6,840

Ending Inventory :

90 units × $11 = $ 990

60 units × $15 = $ 900

70 units × $18 = $ 1,260

Total = $3,150

Weighted Average

A new average cost per unit is calculated with every purchase made.

New Average Cost = (90 units × $11 + 300 units × $15) ÷ 390 units

= $14.08

Cost of Sale , April 4 = 240 units × $14.08

= $3,379.20

New Average Cost = (150 units × $14.08 + 250 units × $18.00) ÷ 400 units

= $16.53

Cost of Sale, Aug 16 = 180 units × $16.53

= $2,975.40

Total Cost of Sales = $3,379.20 + $2,975.40

= $6,354.60

Ending Inventory = 220 units × $16.53

= $3,636.60
