If 200 grams stretches the spring by 5 cm that means 100 grams stretches it by 2.5 so 20 - 2.5 = 17.5 cm is the unstretched length of spring, hope I helped

Answer:
Step-by-step explanation:
let x be the number
6+1/5x=12
1/5x=12-6
1/5x=6
x=5*6
x=30
check: 6+(1/5*30)=6+6=12
Answer:
Present afe of Payal = x yrs.
Therefore, according to question,
Present age of Arav = x/3 yrs.
After 12 yrs.,
Age of Payal = (x+12) yrs.
Hence, we have,
Age of Aarav = [(x/3)+12] yrs.
The problem does not say anything about how many of the marbles are yellow but if you put the first one back in the bag then it is an independent probability and each one would be the same individual probability. Since the problem doesn't say and I don't know if you have it somewhere else, I'll do it as an example.
Let's say there were 6 of the 10 marbles were yellow. So the probability of the first one is 6/10 and so is the second one 6/10. To find the total probability you multiply them together 6/10*6/10=36/100=9/25
Hope that helps. If you can tell me how many yellow there are I will show the work for the specific problem.
