the half life of a medication is the time it takes for the medication to reduce to half of its original amount in a patient's bl
scoray [572]
R=S*0.5^(t/8) 
<span>R is the remaining amount </span>
<span>S is the starting amount (500) </span>
<span>0.5^ is for the HALF in half-life </span>
<span>t/8 show that every 8 ts (every 8 hours), it will be halved once </span>
<span>...so plug in 500mg for the general solution... </span>
<span>R=(500)*(0.5)^(t/8) </span>
<span>... plug in 24h to solve for after 24h </span>
<span>R=(500)*(0.5)^(24/8) </span>
<span>R=(500)*(0.5)^(3) </span>
<span>R=(500)*(0.125) </span>
<span>R=(0.0625) </span>

How do I round 4.75 up to the nearest whole number
Ksenya-84 [330]
4.75.
the whole number is 4
circle 4 and see whether the number beside it
in this case its 7
(Any number that is 5 - 9 causes the number that you are rounding off to to increase)
( any number that is 4-1 causes the number that you are rounding off too to remain)
in this case since its 7 which more that 5 and the whole number increases therefore the final answer is 5.

Hope this helps! xD
would not mind if you put it as the brainliest answer
