assume the substance has a half-life of 11 years and the initial amount is 126 grams.How long will it be until only 15 % remains
Mumz [18]
(126) times (1/2 to the x/11 power) = 15% times 126

(1/2) to the x/11 power = 0.15

Take the log of both sides :

(x/11) times log(1/2) = log(0.15)

Multiply both sides by 11 :

'x' times log(1/2) = 11 x log(0.15)

Divide both sides by " log(1/2) " :

x = 11 x log(0.15)/log(1/2) = <em><u>30.107 years</u></em> (rounded)

That's the time it takes for <em><u>any-size</u></em> sample of this substance
to decay to 15% of its original size.

Segment addition postulate<br> What’s the answer?
Free_Kalibri [48]

\bf Step-by-step~explanation:

Keep in mind: The entire line segment (VX) is equal to 14.

\bf Step~1:

Let's see how the line segment looks like first.

Line segment VX is 14 units long.

             14

______________

V                         X

W is on the line segment somewhere, and VW is equal to 3.

     3              ?

______________

V           W           X

\bf Step~2:

We have to solve for the <em>?.</em> Let's put ? as x. So now we are solving for x.

We have to set up our equation like this:

x + 3 = 14

Since our unknown value plus 3 is equal to 14, we have to subtract 3 from 14 to get our answer.

14 - 3 = 11

   3               11

______________

V           W           X
