Radioactive iodine treatment is so successful at treating hyperthyroidism that it has virtually replaced thyroid surgery. To the

vagabundo [1.1K]

Answer:

56 days

Explanation:

$\sf Half \ Life : A = A_O \ x \ (\dfrac{1}{2} )^{\dfrac{t}{h} }$

where A is final amount, Ao is initial amount, t is time taken, h is half life

Here given:

initial amount: 400 millicuries

final amount: 3.125 millicuries

half life: 8 days

time taken: ?

Hence solve for time taken:

$\sf \rightarrow A = A_O \ x \ (\dfrac{1}{2} )^{\dfrac{t}{h} }$

insert values given

$\sf \rightarrow 3.125 = 400 \ x \ (\dfrac{1}{2} )^{\dfrac{t}{8} }$

divide both sides by 400

$\sf \rightarrow (\dfrac{1}{2})^{\dfrac{t}{8}}=0.0078125$

apply exponent rule

$\sf \rightarrow {\dfrac{t}{8}}=\dfrac{ln(0.0078125)}{ln(1/2)}$

simplify

$\rightarrow \sf \dfrac{t}{8}=7$

multiply both sides by 8

$\rightarrow \sf t = 56$

From home to school, Armen spent 36 minutes walking at a speed of 70 yards per minute. What was his speed, if he spent 8 minutes

hram777 [196]

Answer:

90 yards per minute

Step-by-step explanation:

Armen's time getting back was 36 -8 = 28 minutes. Then the ratio of times is 28/36 = 7/9.

The ratio of speeds is the inverse of this, so his speed coming back is ...

speed/70 = 9/7

Multiplying by 70 gives ...

speed = 70·9/7 = 90 . . . . yards per minute
