Answer:
B
Step-by-step explanation:
Answer:
Rate of interest will be 1.33 %
Return on this investment = 
%
Step-by-step explanation:
We have given principle amount P = $9000
Time = 61 days = 
We have to find the rate of interest
Total amount produce at the end of term = $9020
So interest = $9020 - $9000 = $20
We know that simple interest 
%
Return on this investment = %
Side1 + side2 + side 3 = 84
side1 is the shortest side, and its length is x.
side2 is the middle side, and its length is x + 7
side3 is the longest side, and its length is 2x - 7
x + x + 7 + 2x - 7 = 84
4x = 84
x = 21
side1 = x = 21
side2 = x + 7 = 21 + 7 = 28
side3 = 2x - 7 = 2(21) - 7 = 42 - 7 = 35
The length of the sides are 21 m, 28 m, and 35 m.
Formula to find the slope:
m = y2-y1 / x2-x1
(4,3); (8,5)
m= 5-3 / 8-4
m = 2/4
m = 1/2
Therefore, the slope of the line that passes through these points is 1/2
