Answer:
The interest rate was of 0.1173 = 11.73%.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
In this problem, we have that:
So
So
The interest rate was of 0.1173 = 11.73%.
B. same angle, congruent
c. both angles are 90 degrees so it equals 180 when added together
e. congruent angles
g. supplement means when 2 angles have a sum of 180 and since both are 90 it has a sum of 180
h.
I believe the correct answers are A, B, and D
Switch sides of your problem so it would look like
r -5=-4
20
multiply both sides by twenty
after that it would look like r-100=-80
then add 100 to both of your sides
then after your answer would be r=20
