Mx = (Ax + Bx)/2 My = (Ay + By)
6 = (7 + Bx)/2 5 = (10 + By)/2
12 = 7 + Bx 10 = 10 + By
5 = Bx 0 = By
(5,0)
Answer:
9%
Step-by-step explanation:
Cost of 1/5 good = 1500*1/5= 300
Profit= 5%
SP = (profit+100)/100*CP
SP= (5+100)/100*300
SP = 105/100*300
SP= 1.05*300= 315
Cost of 4/5 good = 1500*4/5= 1200
Profit= 10%
SP= (profit+100)/100*CP
SP= (10+100)/100*1200
SP = 110/100*1200
SP= 1.10*1200= 1320
Total SP = 315+1320= 1635
Net profit= 1635-1500= 135
Profit% = 135/1500*100%
Profit% = 0.09*100%
Profit% = 9%

<em>I think you have forgotten to attach the question. </em>
<em>Anyways....</em>
In order to find the area of a circle use the formula:
π
Where r is the radius
For example the radius is 3cm. The area of the circle will be:
π × 
Since you have taken pi as 3.142...
3.142 × 
3.142 × 9
= 28.278
In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.
= 28.3
