Answer:
Step-by-step explanation:
Half life is the time taken by a radioactive substance to reduce of half of its original size
If the half life of radium is 1600, this means that the original radioactive substance N0 have reduced to N0/2 after 1600 years
if we are given N0 = 1000grams
The amount of the substance that will remain after 1600 years will be N0/2 i.e 1000/2 = 500g
<em>Hence 500 grams of radium will be left after 600years</em>
The price after the discount is $3.706
<h3>Discount price</h3>
Give the following parameters
- cost of ice cream = $4.36
- Percent-off coupon = 15%
Discount = 0.15 * 4.36
Discount = $0.654
Price after the discount = $4.36 - 0.654
Price after the discount = $3.706
Hence the price after the discount is $3.706
