Answer:
A. 31 cm
Step-by-step explanation:
Hopefully its right :)
After the first three days, the sample size will be half of the initial; therefore, 400g/2= 200g. However, it is asking how long will it take to decay to 100g, so we will take 200g/2= 100g, which will take another three days. It will take 2 half-lives, which will encompass 6 days.
In another 30 weeks, because 2x3x5=30 weeks where she does all of the activities.<span />
1200, (2)3+(2)2+2 = 6+4+2 = 12 12(100)= 1200
Answer:
1/4
Step-by-step explanation:
To find slope, we use the formula rise over run (y2-y1 over x2-x1)
So first, our y's: 7-5=2
And our x's: 12-4=8
2/8 simplifies to 1/4
