How do u find a scale factor

1 answer:

5 0

There are a couple steps while finding the scale factor so stick with me. First, the main point is to find the similar figure. You need to find the corresponding side. Now, you write the ratio of the side you got. Begin with the small one, you will get a number below one. If you start with a greater number you will get a greater than the number one.

Consider a home mortgage of $225,000 at a fixed APR of 4.5 % for 30 years. a. Calculate the monthly payment. b. Determine the

White raven [17]

<u>The formula for the monthly payment</u>.....

$M= \frac{P(1+r)^nr}{[(1+r)^n] -1}$ , where P = the principal amount, r = the monthly interest rate and n = the total number of months.

Here annual interest rate is given as 4.5%

So, the monthly interest rate $=\frac{4.5\%}{12}= 0.375\% = 0.00375$

Total number of months $= (30*12)months=360 months$

Also given that, the principal amount is $225000

a. So, the monthly payment will be.....

$M= \frac{P(1+r)^nr}{[(1+r)^n] -1}\\ \\ M= \frac{225000(1+0.00375)^3^6^0*0.00375}{(1+0.00375)^3^6^0 -1}\\ \\ M= \frac{225000(1.00375)^3^6^0*0.00375}{(1.00375)^3^6^0 -1} \\ \\ M \approx 1140$

Thus, the monthly payment will be approximately $1140

b. The <u>total amount paid</u> over the term of the loan will be: $\$ 1140*360 months = \$ 410400$

c. As the principal amount was $225000 , so the amount of interest $= (\$ 410400- \$ 225000)= \$ 185400$

So, the percentage of amount that is paid toward the principal $=\frac{225000}{410400}*100\% =54.82\%$

and the percentage of amount that is paid toward the interest $=\frac{185400}{410400}*100\%=45.18\%$

the museum wants to display all the art pieces in rows. Each row has the same number of pieces and the same type of pieces. How

Alecsey [184]

So if you have 30 oil, 24 photos, 21 sketches, the first thing I notice is that all of these numbers are divisible by 3. Since there are no specifications of how many rows for each category. You can divde the 30/10, 24/8, and 21/7 you would have 10 rows oil, 8 rows of photos, and 7 rows of sketches. In short, I believe your answer should be 3.

Hope this helps! Sorry if this explanation is unclear, please feel free to ask questions. <3
