While taking a hike in the forest, you find some fossils in layers of sedimentary rocks whose age you later find out is said to

cover a span of 100–400 million years. You decide to send the fossils out for analysis to a company that dates rocks by radioactive decay, and, some weeks later, receive a report informing you that a volcanic ash bed associated with one of the fossils has a 1:1 ratio of 235U: 207Pb. Do these data support or refute the assumed age of the rocks in which the fossil was found? (Note: The half-life of 235U is about 700 million years, and its decay product is 207Pb.) Yes, because the ratio of 235U to 207Pb represents one half-life, and that would be approximately 350 million years old. No, because the ratio of 235U to 207Pb represents one half-life, and that would be about 700 million years old. No, because the rock layers are less than 704 million years old. Yes, because the rock layers are less than 704 million years old.

Answer: Yes, because the rock layers are less than 704 million years old.

Explanation: before sending out the fossil sample for examination it was estimated that to be between 100-400 million years old, the data gotten from the results after proper examination supports earlier findings on the age of the rock. Because the fossil dates back to over 350 million years

Total Raw material Available=$103500

Ending Raw material=$33500

Raw material used in production=Total Raw material Available-Ending Raw material

Raw material used in production=$103500-$33500

Raw material used in production=$70000

Indirect materials included in manufacturing=$9400

Direct Material Cost=Raw material used in production-Indirect materials included in manufacturing

On January 1, 2019, Al's Sporting Goods purchased store fixtures at a cost of $180,000. The anticipated service life was 10 year
xz_007 [3.2K]

Answer:

The journal entry is shown below:

Explanation:

The journal entry is as follows for recording the depreciation:

Depreciation expense A/c.........................Dr  $ 14,400

           Accumulated depreciation...............Cr   $ 14,400

Working Note:

Depreciation rate = 100 % / Number of years of life

= 100 % / 10 years

= 10%

This will be multiplied by 2

= 10% × 2

Depreciation rate = 20%

Using the double declining method:

In year 2019

Depreciation expense = Cost of purchasing × Depreciation rate

= $180,000 × 20%

= $36,000

In year 2020

Depreciation expense = ( Cost of purchasing - Depreciation expense of last year) × Depreciation rate

= ($180,000 - $36,000) × 20%

= $144,000 × 20%

= $28,800

Using the Straight Line method:

In the year 2021

Depreciation expense = (Cost of purchasing - Depreciation expense of 2 years) / Number of years of useful life

= ($180,000 - $64,800) /  8

= $115,200 / 8

= $14,400

Arturo would incur an opportunity cost of 36 burritos if he increased his production of tacos by :__________
IrinaK [193]

Arturo would incur an opportunity cost of 36 burritos if he increased his production of tacos by 27

<h3>How to find the opportunity cost</h3>

opportunity cost of Burritos

= 400 / 300

= 1.33

The opportunity cost of Tacos

300 / 400

= 0.75

For the tacos produced we would have

opportunity cost of tacos x opportunity cost that was incurred

= 36 * 0.75

= 27

Hence we would conclude by saying that Arturo would incur an opportunity cost of 36 burritos if he increased his production of tacos by 27

TMS just paid an annual dividend of $2.84 per share on its stock. The dividends are expected to grow at a constant rate of 1.85
bija089 [108]

Answer:

$41.39

Explanation:

Data provided in the question:

Annul Dividend paid, D0 = $2.84 per share

Growth rate, g = 1.85% = 0.0185

Rate of return required, r = 10.4% = 0.104

Now,

Current price of the stock at year 11 = D12 ÷ [ r - g]

= [ $2.84 × (1 + g)¹²] ÷ [ r - g]

=  [ $2.84 × (1 + 0.0185)¹²] ÷ [ 0.104 - 0.0185]

= 3.539 ÷ 0.0855

= $41.39
