The rate of interest is 13%.
Step-by-step explanation:
Given,
Principal (P) = $560
Interest (I) = $145.60
Time (T) = 2 years
To find the rate of interest
Formula
If P principal was invested for T years at r% simple interest, the interest will be I = 
So,
Putting the values of P, I, T we get,
145.60 = 
or, r = 
or, r = 13%
Hence,
The rate of interest is 13%.
Answer:
36
Step-by-step explanation:
9, 18, 27, 36, 45, 54, 63, 72
12, 24, 36, 48, 60
They have a LCM of 36
You can use this equation to help you: (ab)^2 = a^2 b^2. And also (a^m)^n = a^m*n
So, here it is:
(7ab^3)^2 = 7^2 a^2 b^3*2 = 49a^2b^6
The correct answer is the third one - 49 a^2 b^6.
Answer:
