1. The nominal rate on Sandra's loan is 7.125%. If the interest is compounded monthly, what rate of
Mrrafil [7]

Answer:

She is actually paying a rate of 7.36% of interest.

Step-by-step explanation:

The real interest rate, as a decimal, is given by:

I = (1 + \frac{r}{n})^{n}

In which r is the interest rate and n is the number of compoundings during an year.

The nominal rate on Sandra's loan is 7.125%, compounded monthly:

This means that r = 0.07125, n = 12

So

I = (1 + \frac{0.07125}{12})^{12} = 1.0736

As a percentage: 1.0736*100 = 107.36% - 100% = 7.36%

She is actually paying a rate of 7.36% of interest.

ioda

Answer:

Add 1,105.28 + 200.96 + 200.96.

Step-by-step explanation:

we know that

The surface area of the cylinder is equal to

SA=2B+LA

where

B is the area of the circular base

LA is the lateral area

In this problem we have

B=200.96\ mm^{2}

LA=1,105.28\ mm^{2}

substitute

SA=2(200.96)+1,105.28

SA=1,105.28+200.96+200.96

SA=1,507.2\ mm^{2}
