Answer:
5.1 days
Step-by-step explanation:
Given in the question,
initial amount of substance = 34 grams
k-value = 0.137
To find the half life of this substance we will use following formula

here N(0) is initial amount of substance
t is time in days
Plug values in the formula

1/2 = e^{-0.137t}
Take logarithm on both sides
ln(1/2) = ln( e^{-0.137t})
ln(1/2) = -0.137t
t = ln(1/2) / -0.137
t = 5.059
t ≈ 5.1 days (nearest to tenths)
Answer:
225 lo comprarían
Step-by-step explanation:
Para sacar el porcentaje se multiplica el numero por el porcentaje y dividir entre 100
37.5x600/100
37.5x 600= 22, 500
22,500/100= 225
<u>225 lo comprarían </u>
Pretty sure it's A ?? That's what I got. I'm taking this right now.
Lets make it an improper fraction
5/3
we do not know how many chains so we'll put the (x)
therefore
5/3x=9.00
x= 5.4
