Answer: 30g
Step-by-step explanation:
In this question (t½) of isotope is 40 days, which means that after 40 days half of the sample would have decayed and half would be left as it is.
After 40 days ( first half life) 240 /2 = 120 g decays and 120 g remains left.
After another 40 days ( two half lives or 80 days) 120 /2 = 60 g decays and 60 g remains left .
after three half lives or 120 days, 60/2 = 30g decay and 30 g of the isotope will be left.
Answer:
x = 2
Step-by-step explanation:
Given that:
Your score = 5
We have to find scores of opposite team let it be x
According to given conditions:
Opponents score: (1/2)x+ 4 = 5
By simplifying:
subtract 4 from both sides:
(1/2)x + 4 -4 = 5-4
(1/2)x = 1
Multiply both sides by 2 we get
2*(1/2)x = 1*2
x = 2
Proof:
(1/2)x+ 4 = 5
Put x= 2
(1/2)*2 +4 =5
1 +4 =5
5=5
Hence proved
I hope it will help you!
