If the simple interest on $7000 for 10 years is $6300, then what is the interest rate? I will pick branliest answer with the

Roman55 [17]

Answer:

0.09

Step-by-step explanation:

So if you use the Simple interest equation it will begin with:
Interest total = Initial Amount of money x Interest rate per year x Years money is invested for.

Then substitute the values you have been given so:

$6300 = 7000 x Interest rate per year x 10.

This is simplifies to 6300 = 70,000 x Annual Interest rate

You can rearrange this to find the annual interest rate by dividing by 70,000:
$\frac{6300}{70000} = Interest\ rate$

Simplifying this would be:
$\frac{63}{700}\\$ = Interest rate.

The interest rate is 0.09.

A bag contains A markers, 3/8 of which are red. How many other color markers are in the bag?

vagabundo [1.1K]

8 is the total number of markers in the bag. There are 3 out of 8 that are red. 8-3=5 so there are 5 out of 8 markers that are not red and that are other colors - or 5/8 are other colors.
