$120*.09+$120=$130.80
$10.80 in Tax
B.120/x=100/9
Where the coordinates of a points pedepend on the distance to the origin of the coordinate system and also depend on the angle, the coordinate system is a POLAR coordinate system.
1. 20% means 20/100 or 2/10
so 2/10 of 1000=spanish=200=spanish
2.6%=6/100
6/100 times 1000=60
3. so 12%of 6th graders=24
divide by 6
2%of 6th graders=4
multiply by 50
100%of 6th graders=200
200 6th graders
4. so 5%=5/100=0.05
so tax=13.75 times 0.05=0.69
tax=69 cents
13.75+0.69=14.44
7 or 8 since 2 and a half hours isnt an even amount of time so thered be an extra 10 minutes
