Danny bought a new year. The total amount she needs to borrow is $19,541. She plans to take out a six-year loan at an APR of 8.3

lys-0071 [83]

Present value of loan, P = 19541
monthly interest rate, i = 8.3%/12
repayment period = 6 years = 72 months

Monthly payment,
$A=\frac{P(i*(1+i)^n)}{(1+i)^n-1}$
$=\frac{19541(.083/12*(1+.083/12)^{72})}{(1+.083/12)^{72}-1}$
$=345.487$
$=345.49$ to the nearest cent

Levi wants to order the fractions 1/3, 2/5, and 11/30 in descending order? How can you help him by using a common denominator? E

Georgia [21]

Answer:

The correct order of fractions in descending order will be:

$\frac{2}{5}, \frac{11}{30}, \frac{1}{3}$

Step-by-step explanation:

Given fraction:

$\frac{1}{3}, \frac{2}{5}, \frac{11}{30}$

To arrange them in descending order.

Solution:

In order to arrange the fractions in descending order, we will have to find the least common denominators.

To find the least common denominator, we will find the least common multiple of the denominators 3,5, and 30.

Since 30 is a common multiple of all 3 numbers, so it will be the least common denominator.

So, we multiply the numerators and denominators with same numbers in order to make the denominators = 30.

So, we have:

$\frac{1}{3}, \frac{2}{5}, \frac{11}{30}$

⇒ $\frac{1\times 10}{3\times 10}, \frac{2\times 6}{5\times 6}, \frac{11\times 1}{30\times 1}$

⇒ $\frac{10}{30}, \frac{12}{30}, \frac{11}{30}$

Now, we compare the numerators and arrange them accordingly.

$\frac{12}{30} > \frac{11}{30} > \frac{10}{30}$

So, the correct order of fractions in descending order will be:

$\frac{2}{5}, \frac{11}{30}, \frac{1}{3}$

What is the square root of the number 441? How do you know this and how did you solve this?

nalin [4]

The square root of 441 is 21. for this kind of question you should know 11^2 is 121 so now you should choose a bigger number for 441. it does not have any formula. :))
i hope this is helpful
