Answer:
-6/7
Step-by-step explanation:
The slope of DE is ...
(change in y)/(change in x) = (y2 -y1)/(x2 -x1) = (-3-4)/(1-7) = -7/-6 = 7/6
The slope of the line perpendicular to DE is the negative reciprocal of this:
perpendicular slope = -1/slope = -1/(7/6) = -6/7
___
Answer:
sp with vat=20700
sp+vat%of sp=20700
sp(1+15/100)=20700
sp=20700/1.15=18000
Step-by-step explanation:
vat amount=vat%of sp=15/100×18000=2700
40% of 120 is 48
1/4 of 200 is 50
1/4 of 200 is bigger.
If you add all of those up you get a total of 1,407
