Answer: 13%
Step-by-step explanation:
The formula to find the simple interest is given by :-
, where P is the principal amount, r is rate of interest () in decimal and t is the time ( in years).
Given : P = $19,100 , I=$9932.00 and t= 4 years
Substitute all the above values in the formula , we get

In percent , 
Hence, the rate of interest = 13%

Answer:
(x, y) = (3, -1)
Step-by-step explanation:
The solution to the system of equations is the point where the lines intersect.
(x, y) = (3, -1)
Answer:
B = 50 & C = 130
Step-by-step explanation:
I really don't know how to explain but 180 - 50 = 130 for C and 50 is the measurement for B
Answer:
∠2 = 51°
Step-by-step explanation:
The sum of supplementary angles = 180°
Equate the sum of the angles to 180 and solve for a
11a + 19 + 6a - 9 = 180
17a + 10 = 180 ( subtract 10 from both sides )
17a = 170 ( divide both sides by 17 )
a = 10
Hence
∠2 = (6 × 10) - 9 = 60 - 9 = 51°
