The annual interest rate is 6% and this can be determined by using the formula of simple interest and also by using the given data.
Given :
Tammi deposited $520 into a bank account that earned simple interest each year. After 5 years, she had earned $156 in interest.The formula of the simple interest can be used in order to determine the annual interest rate.
The formula of the simple interest is given by:
A = P(1 + rt)
where A is the final amount, P is the principal amount, r is the rate of interest, and t is the time in years.
Now, substitute the values of the known terms in the above formula.
520 + 156 = 520(1 + 5r)
Simplify the above expression in order to determine the value of 'r'.
676 = 520(1 + 5r)
1.3 = (1 + 5r)
0.3 = 5r
r = 0.06
Now, multiply by 100 in order to determine the percentage.
r = 0.06 [tex]\times[/tex] 100
r = 6%
So, the annual interest rate is 6%.

An “A” train leaves a subway station every 12 minutes. An “E” train leaves every 9 minutes. If both trains just left the station on parallel tracks, when will both leave the station together again?
A. in 108 minutes
B. in 36 minutes
C. in 72 minutes
D. in 24 minutes
B. In 36 minutes because 12×3=36 and 9×4=36 and this is the first number they share.
The A train and the E train will both leave the station together again in 36 minutes. Hence the correct option is B.
To find out when both the A train and the E train will leave the station together again, we need to calculate the Least Common Multiple (LCM) of their departure intervals, which are 12 minutes for the A train and 9 minutes for the E train. To find the LCM, we list multiples of each:
Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108...
Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108...
We can see that the common multiples of 9 and 12 are 36, 72, and 108. The smallest of these is 36 minutes, so that is the first time they will both leave the station together after initially departing at the same time.
Therefore, the correct answer is B. in 36 minutes.

Solve for n.
25n−3=5n+8
the n-3 and n+8 are powers
Final answer:
The equation 25n⁻³ = 5n⁺⁸ suggests an incorrect use of exponents, as no solution exists if we assume the bases should be the same. However, if the bases are 25 and 5, after simplifying, we find that the solution is n = 14.
Explanation:
To solve the equation 25n⁻³ = 5n⁺⁸, we need to use properties of exponents and logarithms. Here are the steps:
Assuming the bases are the same and only the exponents are different, equate the exponents: n - 3 = n + 8.This implies that no solution exists because once the bases are the same, the exponents on both sides must be equal for the equation to hold true, but here they are not.Alternatively, if 25 and 5 are the bases, we can rewrite the equation as (52)n-3 = 5n+8, then applying properties of exponents gives us 52n-6 = 5n+8. Equating the exponents yields 2n - 6 = n + 8, which we can solve for n.
Subtract n from both sides: n - 6 = 8.Add 6 to both sides to isolate n: n = 14.A particular amusement park ride will make 156 revolution in 180 seconds. At this rate, how many revolutions will it make in 2 minutes?
