If you borrow $500 from a credit union at 12% annual interest and $250 from a bank at 18% annual interest, what is the effective annual interest rate (that is, what single rate of interest on $750 would result in the same total amount of interest)? a. 10% b. 12% c. 14% d. 15%

14% that is option c is correct.

Step-by-step explanation:

We have been given that $500 from a credit union at 12% annual interest and $250 from a bank at 18% annual interest

That means  we will get

Since, we need to find the single rate of interest on 750

So, the required rate of interest will be:

That is 14%

Therefore, option c is correct

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

only 10/60 isn't equivalent

hope this : )
