Use the formula,
I = Prt
P = Principal amount = 400
I = interest = 18
r = annual rate
t = time in years = 9/12 = 3/4
so,
18 = 400*r*3/4
r = 0.06
so the annual interest rate is 0.06 or 6%.
Check the picture below.
how many times does 125 go into 1000? that many will fill it up.
It would be 1.675 inches away from each corner.
The most efficient way of finding the answer to this question is first reducing 10-24-26 and comparing it with the first 5 combinations for right-angled triangles:
First, reduce 10-24-26 by dividing it by the GCF (greatest common factor).
10-24-26 divided by its GCF, 2, is: 5-12-13
Now comparing it with the first 5 combinations for right-angled triangles:
1) 3-4-5
2) 5-12-13
3) 7-24-25
4) 8-15-17
5) 20-21-29
As you can see, number 2 is the same as our reduced example. Therefore, we know that 10-24-26 is a right triangle.
Hope this helps!
