Cindy says that 1/3 is an irrational number because the fraction form doesn't terminate. Construct an argument to support or refute Cindy's position.

Answers

It’s not an irrational number because it can be written as a decimal. It is in an infinite decimal but if anything can be written as a fraction it is not a irrational number. :))

Final answer:

Cindy's argument is incorrect. 1/3 is a rational number because it can be expressed as the ratio of two integers. The fact that the decimal representation of 1/3 does not terminate does not make it irrational.

Explanation:

Cindy's argument is incorrect. A fraction is considered irrational if it cannot be expressed as the ratio of two integers. In the case of 1/3, it can be expressed as the division of the integer 1 by the integer 3, so it is a rational number. The fact that the decimal representation of 1/3 (0.333...) does not terminate does not make it irrational. Irrational numbers are decimal numbers that do not repeat or terminate, such as π (pi) and √2 (the square root of 2).

The cost of $500,000 worth of 20-year term life insurance for Derek is $96.21 per month. If Derek's employer covers 85% of this cost, how much is deducted from Derek's gross income per year for life insurance?

Answers

Alright, the first thing we should have to do is find the total cost per year of his insurance. To do that, we multiply $96.21 by the 12 months in a year to get $1154.52. This is the cost of his insurance per year.

Next, we need to find out how much his boss covers, which we know is 85% of the total cost. SO what we can do is multiply the yearly cost ($1154.52) by the percent his boss covers (.85) to get $981.342. This is how much his boss covers per year.

Lastly, to find out how much Derek pays for insurance yearly, we just need to subtract how much his boss pays ($981.342) from the total yearly cost ($1154.52), which leaves us with $173.178, which is how much Derek pays yearly for his insurance, which should be your answer.

Final answer:

Derek pays 15% of the yearly cost of his life insurance, which amounts to $173.18 per year.

Explanation:

The total cost of Derek's life insurance for a year is calculated by multiplying the monthly fee by the number of months in a year (i.e. $96.21 x 12 = $1154.52). As Derek's employer is covering 85% of the cost, Derek is responsible for the remaining 15%. Therefore, the yearly cost deducted from Derek's gross income would be $1154.52 x 15% = $173.18. It's crucial to understand that these costs can vary depending on the insurance coverage, the employee benefits provided by the employer, and the individual's income.
