So if you do 3/5 it ends up equaling .6 you can convert that into a percent and it equals 60%
Answer:
five and forty-six hundredths
Step-by-step explanation:
Answer:
t = 6.3
Step-by-step explanation:
N=Noe^(-kt)
No = 14 grams
k = .1092
We want to find t when N = 7 or 1/2 of 14
N=Noe^(-kt)
7 = 14 e ^ (-.1092t)
Divide each side by 14
1/2 = e ^ (-.1092t)
take the natural log of each side
ln (1/2) = ln e ^ (-.1092t)
ln (1/2) = -.1092t
Divide each side by -.1092
ln (1/2)/ -.1092 = t
t≈6.3475
Rounding to the nearest tenth
t = 6.3
The answer will be 400.
In order to get this answer by estimating 206 to 200 and 167 to 200. Finally you add 200 to 200 to get 400 as your final answer.
