Answer:
$160.16
Step-by-step explanation:
143 is his bill
he leaves an extra 12%
12% of 143 = 0.12 x 143 = 17.16 that's his time
143 + 17.16 = 160.16
x=9 units, y=12 units, u=24 units and v=32 units
Step-by-step explanation:
The question is on similarity.
The ratio of corresponding sides should be equal for the triangles to be similar.
Finding x
20/5=(3+x )/3
apply cross product
60=15+5x
60-15=5x
45=5x
45/5=x
9=x
Finding y
20/5=(4+y)/4
Apply cross product
80=20+5y
80-20=5y
60=5y
60/5 =y
12=y
Finding u after replacing values of x and y
60/20 = (12+u)/12
perform cross product
720=240 +20 u
720-240 =20u
480 =20 u
480/20 =u
24 =u
Finding v after replacing values of x and y
60/20 = (16+v)/16
perform cross product
960=320+20v
960-320 = 20v
640=20v
640/20 =v
32= v
