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:
5x+1
Step-by-step explanation:
2x+3
*4x-5
=8x-15
Now you find the area of the white region
3x+2
*2-8
=3x+16
Now you subtract
8x-15
-3x+16
=5x+1
see attached. i hope this helped
