Answer:
Step-by-step explanation:
Interest earned during the rest of 2 years and 6 months 
 40 + 40 + 40 = 120 
he will be getting 1000 at the time of maturity ie after 2.5 years . 
Total receipt = 1000 + 120 = 1120 
investment made = 820 
total receipt earned = 1120 
profit made = 300 
time = 2.5 years 
profit = investment x rate of intt x time / 100 
300 = 820 x r x 2.5 / 100  where r is rate of interest 
r = 30000 / 820 x 2.5 
= 14.63 % . 
 
        
             
        
        
        
Answer:
360°
Step-by-step explanation:
Each of the two triangles have 3 angles that add up to 180°. 
So, 
180° + 180° = 360°
The sum of the angles of a quadrilateral is 360°
 
        
             
        
        
        
Answer:
Line N is a vertical line with an undefined slope
Step-by-step explanation:
To find slope we do (y2-y1)/(x2-x1)
So we do that with (-1,4) and (-1,-4)
(-4-4)/(-1-(-1))
-8/0
Since the denominator is 0, that means the slope is undefined because you cannot divide by 0
 
        
             
        
        
        
Let w won games, t tied games, s lose games
s=4w
t=w-5
s+t+w=43
4w+(w-5)+w=43
6w=48
w=7
s=4*7=21 games lost
