Answer:
1/27 or -3^3
Step-by-step explanation:
3 cubed is 3x3x3 which is 27x 3^4 which is 3x3x3x3 or 81
once you multiply 27 by 81 you get 2187
divide 2187 by 3^10 or 59049
once you divide you get the answer hope this helps. I also feel like an idiot sometimes trust me. I ate a hamster treat once so if you ever feel bad remember there is someone out there who ate a hamster treat and drinks paint water.
To simplify the problem imagine the half-life was 2.5 minutes. This means that there would be 10/2.5=4 periods of halving the mass, which means 1/2⁴=1/16 of 18g=1.125g.
So for the given half-life we calculate 10/2.552=3.9185 approx. So we now find 2 to this power=15.1211 approx and divide into 18=1.19g. This is close to the rough estimate we did earlier.
Rightttt! I hate it but I have no idea haha
First, do 100-14 to find out how much percent doesn't get the coupon= 85
then find 85% of 64= 54.4
finally, your answer is: 54.4
