F[c(p)] = 0.81p. I hope this helps :) Please give me a rate and thanks :P
V = 160 if did my math correct
<span />
4x+10=5x-3
Subtract 4x from both sides
10= 5x-4x-3
Add 3 to both sides
13=x
4(13)+10
52+10
Q=62
Answer:
It will take 13.58 minutes until there are 80 grams of the element remaining
Step-by-step explanation:
An element with a mass of 990 grams decays by 16.9% per minute.
We are supposed to find how long will it be until there are 80 grams of the element remaining
Formula :
N(t)=Amount after t minutes
=Initial amount
r = rate of decrease = 0.169
t = time in minutes
Substitute the values in the formula :
t=13.58
Hence It will take 13.58 minutes until there are 80 grams of the element remaining
