Hey there!
Here is your answer:
<u>The proper answer to this question is "40".</u>
Reason:
<u>40/x=100/45</u>
<u>(40/x)*x=(100/45)*x - we multiply both sides of the equation by x</u>
<u>40=2.22222222222*x - we divide both sides of the equation by (2.22222222222) to get x</u>
<u>40/2.22222222222=x </u>
<u>18=x </u>
<u>x=18</u>
<span>45% of 40=18

Answer:
60inches
Step-by-step explanation:
this because If you multiply 4 by 10 equals 40 add 40 to 20 equals 60
Option 3
Step-by-step explanation:
You bring the like-terms together and then do the math
<span>Assuming the reaction is of 1st order, we can
start using the formula for rate of 1st order reaction:</span>
dN / dt = k * N
Rearranging,
dN / N = k dt
Where N = amount of sample, k = rate constant, t = time
Integrating the equation from N = Ni to Nf and t = ti to
tf will result in:
ln (Nf / Ni) = k (tf – ti)
Since k is constant, we can equate to situations.
Situation 1 is triple in size every days, situation 2 is after 20 days.
ln (Nf / Ni) / (tf – ti) = k
ln (3Ni / Ni) / 4 = ln (Nf / 40) / 20
Calculating for Nf,
<span>Nf =
