A Riemann sum approximates the area of a certain region. Usually it's used in calculus, where you use the Riemann sum to approximate the area a curve instead of using an integral to find the exact value, since that tends to take a lot more time and effort.
7/10 is 0.7
0.7 x 16 yields 11.2
11.2 is also 11 1/5
or 56/5
It's 4/3 because of the distance formula
Answer: $12000 was invested at 7% while $8000 was invested at 9%.
Step-by-step explanation:
Based on the information given in the question, let the amount that was invested at 7% be n.
Therefore,
0.07n + 0.09(20000 - n) = 1560
0.07n + 1800 - 0.09n = 1560
-0.02n = 1560 - 1800
-0.02n = -240
n = 240/0.02
n = 120
Therefore, $12000 was invested at 7% while $8000 was invested at 9%.
