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

The cost here is $357,000 when compared to net realizable amount of $819,000,the cost is lower,hence the stock of the insecticide would be shown in the balance sheet as an asset,supplies ,in the amount of $357,000

The supplies would an a current asset in the balance sheet,hence when it is used supplies would be credited while supplies expense is debited

Illusion [34]

Answer:

Start-up cost; variable cost

Explanation:

Start-up cost is the cost incurred in developing a new product. It is a one time cost that is incurred only at the time of creating something new. Start-up cost includes borrowing cost, research and development cost and expenses incurred on technology.

Variable costs change with the change in units of output produced. Cost of chemicals depend on the amount of drugs produced. So, research and development cost is start-up cost and cost of chemical is variable cost.
