Answer:
yes
Step-by-step explanation:
After each hour 60% ( or 0.60) of the drug will be present.
The equation is A = 100(0.6)^t where t = time in hours. (answer)
First, 10 1/2 is the same as 21/2
If there are 12 inches in a foot then
21/2*12=126 inches
You just add all the numbers together:
3 1/8+ 4 1/2+ 4 1/4
=25/8+9/2+17/4
=25/8+36/8+34/8
=95/8
=11 7/8
Ugh.. did you type in the numbers correctly? My guess would be it was meant to be B tho :)
