The length of each of its parallel side are 30 cm and 40 cm.
<u>Step-by-step explanation</u>:
- Perimeter of parallelogram = 140 cm.
- The one side of parallelogram = x cm.
- The other side of parallelogram = x+10 cm.
Perimeter of a parallelogram = 2 (base+height)
⇒ 140 = 2(x+x+10)
⇒ 140 = 2(2x+10)
⇒ 140 = 4x+20
⇒ 4x = 120
⇒ x = 120/4
x = 30 cm
∴ The longer side = 30+10 = 40 cm
Population is 200 and sample is 30

Answer:
hello fellow earthling
Step-by-step explanation:
I think it would be B i hope this helps
2c+5t=43
c=(43-5t)/2
8c+3t=36 and using c found above in this equation gives you:
4(43-5t)+3t=36
172-20t+3t=36
-17t=-136
t=8, and since c=(43-5t)/2
c=1.5
So a table costs $8.00 to rent and a chair costs $1.50
