Answer:
40/3 option B
Step-by-step explanation:
20-10+5-5/2+ ...
We need to find the sum of infinite geometric series

a is the first term (20)
r is the common ratio
To find common ratio we divide second term by first term
r=
now we plug in the values




sum = 40/3

The number of students who enrolled in business mathematics alone can be calculated by subtracting the number of students enrolled in both from the total number of students enrolled for business mathematics.
x = 600 - 173 = 427
In similar manner, we solve for the number of students enrolled for only statistics
y = 300 - 173 = 127
The total number of students enrolled in two courses altogether is the sum of x and y and 173.
T = 427 + 127 + 173 = 727
Thus, all in all there are 727 students enrolled in the two courses.
Well to find the angles, simply see what must the angles be, to equal to 180 or 90 degrees. So we know the angle between C and D would be 90 degrees, so will the angle between A and C. The angle between B and A and the angle between B and C must give us a total of 90 degrees, so that means each would be 45 degrees. As 45 + 45 = 90. Also I would assume that angle between D and F would also be the same as between B and A which would be 45 degrees. Finally the angle between A and F would be the difference between 180 and 45 degrees. So it would be 180 - 45 = 135 degrees.
If I understand this correctly you would multiply $1.10 by 310 and you should get your answer.
