Answer:
Your number is (3 sqrt(2)) / sqrt(2) = 3, and is a rational number indeed. I don't know exactly how to interpret the rest of the question. If r is a positive rational number and p is some positive real number, then sqrt(r^2 p) / sqrt(p) is always rational, being equal r. Possibly your question refers to situtions in which sqrt(c) is not uniquely determined, as for c negative real number or complex non-real number. In those situations a discussion is necessary. Also, in general expressions the discussion is necesary, because the denominator must be different from 0, and so on.

Answer: Yes, I agree. $10 will be withdrawn every Friday, resulting in the $100 she deposited being completely gone after 10 withdrawals.
Step-by-step explanation: You will want to find the amount of money being taken from the $100 withdrawal first. Turn the percent into a decimal, which should result to 0.10. Take this decimal and multiply it with 100 to get the amount of money being taken out of the account each week, which should be $10. I would go about answering this by multiplying the $10 by the amount of 10 withdrawals. This would result in 100. This answers the question because we are trying to see if 10 withdrawals will completely deplete the $100 in the account.

42 is itself it's highest common factor
Answer:
B. $444.44
Step-by-step explanation:
We have been given that Andrew buys a home entertainment system from an electronics store offering 0% interest for 18 months. This means if she pays monthly payment she will not be charged with any interest for 18 months.
As Andrew will make 18 payments in 18 months, so payment for each month can be found by dividing total cost of entertainment system by 18.
Therefore, Andrew should make a monthly payment of $444.44 to avoid paying deferred interest charges for the $8,000 system. and option B is the correct choice.
