Step-by-step explanation:
a) gradient= y2-y1/x2-x1
gradient of AB:
gradient=-4-1/2-3
=-5/-1
=5
gradient of BC:
=-5+4/7-2
=-1/5
b) as the priduct of both gradient is -1 ,both lines are perpendicular.
c) as we have seen lines are perpendicular so it is a right angled triangle.
John get money $630 and bill get money $270.
Given that John and bill shared $900 in the ratio 7:3 respectively.
The ratio is defined as the comparison of two quantities of equal units, indicating the quantity of one quantity contained in the other quantity.
The total ratio is 7+3=10
For john:
John has money seven out of 10 for the $900, we get
J=900×(7/10)
J=90×7
J=630
For bill:
Bill is three out of ten for $900, we get
B=900×(3/10)
B=90×3
B=270
Hence, john get money $630 and bill get $270 when they both shared $900 in the ratio 7:3 respectively.
