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:

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

<u>insert values given</u>

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

<u>divide both sides by 400</u>

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

<u>apply exponent rule</u>

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

<u>simplify</u>

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

<u>multiply both sides by 8</u>

$\rightarrow \sf t = 56$

How do you decide by which power of 10 to multiply an equation when writing a decimal with repeating digits as a fraction?

Soloha48 [4]

For the repeating fraction, It depends on the denominator as which power of 10 is the nearest factor of denominator.

According to the statement

we have to find that the power of 10 which is multiply the equation by which writing a decimal with repeating digits as a fraction.

So, For this purpose, we know that the

Fraction is a number expressed as a quotient, in which a numerator is divided by a denominator. In a simple fraction, both are integers.

So, From the given information:

To decide the power of 10 to multiply an equation with repeating digits ; Round the equation to the required significant numbers.

when the numerator of an equation is divided by the denominator and the result is not a whole number ( i.e. number with some decimals)and sometimes the decimal places are unending. to present the result properly we have to round off the number to the nearest significant number, then you can multiply the equation with the power of 10, in relation to the number of significant places you rounded off.

Example :

5/200 = 0.025

To express this answer with the power of 10

0.025 = 2.5 * 10^-2

Here the power of 10 is -2.

So, For the repeating fraction, It depends on the denominator as which power of 10 is the nearest factor of denominator.

Answer if u actually know it only!!

irina [24]

Answer: 2^5

Step-by-step explanation: Diego should have added the exponents instead of multiplying them. I know it sounds weird but because both of the numbers are 2's you are able to combine them. When multiplying them together you should keep the base the same and add the exponents. In this case, 2^2 x 2^3 would be 2^5. Hope this helps.
