Answer:
Perimeter is 38.8 units and approximately 39 units
Step-by-step explanation:
Given: Graph
To find: perimeter of the polygon
Solution:
Distance between points 
is given by 
As per the graph,
point P is (-2,11)
point Q is (-4,6)
point R is (2,0)
point S is (1,7)
point T is (8,7)
Perimeter refers to sum of lengths of all the sides.
Perimeter = 
Or approximately 39 units
Given:
hourly rate = 11.50
hours worked in a week = 40 hours
taxes per moth = 60
Every month may be 4 weeks or 5 weeks but we know that 1 year has 52.1429 weeks.
Let us compute for the whole year:
Earnings:
11.50 /1 hour * 40 hours/1week * 52.1429 weeks/1year
= 11.50 * 40 * 52.1429/year
= 23,985.734 per year
Taxes:
60 / per month * 12 months / 1 year
= 60 * 12/year
= 720 per year
Net earning per year
23,985.734 - 720 = 23,264.734
Net earning per month
23,264.734 ÷ 12 months = 1,938.81
You will earn 23,264.73 annually from a monthly earning of 1,938.81
What's the problem you need help with
Average speed of cyclist = x
average speed of car = 3x
x = 225/5
x = 45km/h
3x = 3(45)
3x = 135km/h
average speed of cyclist = 45km/h
average speed of car = 135km/h
Fractions that aren't equivalent would be 30/60, 34/60 and anything that cannot be the same as 36/60.
