The half-life of Radium-226 is 1590 years. If a sample contains 400 mg, how many mg will remain after 2000 years?

Assoli18 [71]

Answer:

167.27 mg.

Step-by-step explanation:

We have been given that the half-life of Radium-226 is 1590 years and a sample contains 400 mg.

We will use half life formula to solve our given problem.

$N(t)=N_0*(\frac{1}{2})^{\frac{t}{t/2}$ , where N(t)= Final amount after t years, $N_0$ = Original amount, t/2= half life in years.

Now let us substitute our given values in half-life formula.

$N(2000)=400*(\frac{1}{2})^{\frac{2000}{1590}$

$N(2000)=400*(0.5)^{1.2578616352201258}$

$N(2000)=400*0.4181633028874878239$

$N(2000)=167.26532115499512956\approx 167.27$

Therefore, the remaining amount of Radium-226 after 2000 years will be 167.27 mg.

Terry bought a sweater for$24 before tax he had a coupon for 1/4 off the sales tax rate was 6%. How much did terry pay for the s

Ira Lisetskai [31]

Answer: Terry paid $18.36 for the sweater.

Step-by-step explanation:

Given: Sales price of sweater = $24

Coupon states $\dfrac14$ off the sales, i.e. Terry will get $\dfrac14\times24=\$6$ discount.

Also, tax rate = 6%

Tax will be charged = 6% of Sales price of sweater

= 0.06 x 6

= $0.36

Now , Final amount for Terry = Sales price - discount +tax

= $(24-6+0.36)= $18.36

Hence, Terry paid $18.36 for the sweater.
