Answer:
The best approximation is 
Step-by-step explanation:
we know that
The area of the circle is equal to
In this problem we have
substitute
I think the answer is yes
Recall that to compute for the new amount of the original sum at a compound interest is
A(t) = P(1 + r/n)^(nt)
where P is the original amount, r is the interest rate, n is the number of times P is compounded each year, and t is the number of year.
With this, the total amount owed by Sam in five full years becomes [(120)(1 + 0.30/12)^60 ]. The total interest is the difference between the original amount owed and the amount that needs to be paid over time. Thus, total interest is [(120)(1 + 0.30/12)^60 ] - 120 = 407.97.
Therefore, the total interest is $407.97<span>.</span>
The person at the top is correct.
Answer:
400
Step-by-step explanation:
25% = 1/4
you can ultimately take this fraction and see that if you add two zeroes at the end of '1', you get 100
although, because you added two zeroes at the top, you have to do the same to the bottom.
this shows 400; 25% of 400 is 100.
