Thorium -228 is a radioactive substance that decays 50% every 1.9 years. How much of a 50 gram sample will exist after 22.8 year
Evgesh-ka [11]

Answer:

A=0.0122\ gr

Step-by-step explanation:

The exponential decrease formula that we must use is:

A=A_0e^ {-kt}

Where A is the amount of thorium as a function of time

A_0 is the initial amount and k is the decrease rate

We know that initially there are 50 gr and that you decay 50% every 1.9 years.

So

A=A_0*0.5=50*0.5 = 25\\\\t=1.9

25=50e^ {-k(1.9)}

We solve the equation for k

0.5=e^ {-k(1.9)}

ln(0.5)=ln(e^ {-k(1.9)})

ln(0.5)=-k(1.9)

-1.9k=ln(0.5)

k=-\frac{ln(0.5)}{1.9}\\\\k=0.3648

After 22.8 years the amount of thorium that exists is:

A=50e^ {-0.3648(22.8)}

A=0.0122\ gr

Show how to solve the problem 378×6 using place value with regrouping. Explain how you knew when to regroup
nekit [7.7K]
<span>1. 6 (378) = 2268 = (189 + 189)6


Properties are:
Addition, you can have 6 + 107 = 113 </span>
<span>Commutative Property by moving: 107 + 6 = 113 </span>
<span>Associative Property by grouping: (3 + 3) + (100 + 7 ) = 113 </span>
<span>Distributive Property by allotting: 2 (3) + 107 = 113   </span>

<span>Multiplication, you can have 6 x 107 = 642 </span>
<span>Commutative Property by moving: 107 x 6 = 642 </span>
<span>Associative Property by grouping: (3 + 3) x (100 + 7 ) = 642 </span>
<span>Distributive Property by allotting: 2(3) x 107 = 642<span>
</span></span>
