nope.
9/12 of 120 = losers = 90 losers
3/12 = winners = 30 winners
revenue from 120 entries = 120 x 20 = 2400
30 winners x 30 = 900 paid out
2400-900 = net 'winnigs' = 1500 (you had it correct)
The slope of the given line = m = 3/2 perpindicular is - 1/m = -2/3
which answer(s) have slope = -2/3 ????
First part is pretty simple:
B. 3 out of 12 is a 7 9/12 is NOT a 7 9/12 (of 120 people) will lose 3/12 will win
can you doit from this partial solution?
As Hec solves above. remember slope = rise / run 'rise' would be the y direction ' run' would be the x direction
then use the formula in Hecticar's answer and note it does not matter which point you call x1 y1 or x2 y2
FIrst is it a right triangle ? 15^2 + 18^2 = 21^2 No it is not
Try using Heron's Formula
At LEAST post your question imgaes right side up ! And PLEASE do NOT POST more than ONCE !
A Emma 3 + 2n
Alex 1 + (2n+2)
B Red is constant term
C Emma starts with 3 and adds 2 for each n
Alex starts with 1 and adds (2n+2 ) for each n
I think 18% is above their usual earning rate
1.18 (4 weeks ) x = 2800 where x is usual pay rate per week
x = $ 593 .22 /week
So if they usually earn 593.22 per week
593.22 = 2372.88
their loading bonus would be 2800- 2372.88 = 427.12 for 4 weeks ....= 106.78 bonus per week
It would just be the slope of the line for the van 3240 every increase of one for x , costs equation increases 3240
Sorry....some people just post answers with no explanation....be careful, they are often incorrect.
