Answer: $54

Step-by-step explanation:

if we divide 42 by 7, or we divide 48 by 8, we can see that it is 6. so, one shirt costs $6. then, we just multiply 9 (the amount of shirts) by 6 (the cost of a shirt), and we get 54.

Nickel-63 has half-life of about 96 years. after 336 years,about how many milligrams of an 800 mg sample will remain?
vagabundo [1.1K]
F=ar^t if the half-life is 96 years...

.5=r^96

ln(.5)=96lnr

ln(.5)/96=lnr

r=e^((ln.5)/96)

f=800e^(336(ln.5)/96)

f=70.71

So about 71mg will remain after 336 years.
