1.3 george invested n$ 12550 for 5 years. after 5 years, he received a total amount of n$ 22500 from his investment. calculate the annual rate at which interest was paid? (5)

12.38%

Step-by-step explanation

In this case its is very useful to know the Future Value formula:

where FV= future value

PV= present value

i= interest rate and

n= number of periods

Since, FV=22500, PV=12550 and n= 5 years, we can solve i:

i=12.38%

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
