Answer:

556

Step-by-step explanation:

The simple interest is 1.4%, so first we need to work out what 1.4% of 500 is:

500 x 0.014 = 7

It has since been 8 years when he put the money into the account, so now we multiply this amount by 8:

7 x 8 = 56

So JD's total savings is 500 + 56 = 556 (and whatever currency you use)

The​ half-life of radium is 1690 years. If 20 grams are present​ now, how much will be present in 250 ​years?
Aneli [31]

Answer:

  18.05 g

Step-by-step explanation:

The multiplier of the initial quantity is ...

  (1/2)^(t/1690)

so, for t=250, this becomes ...

  (1/2)^(250/1690) ≈ 0.902545

Then the quantity remaining of the initial 20 g is ...

  (20 g)(0.902545) ≈ 18.05 g
