Answer: ![1.663\times 10^{30}\ gm](https://tex.z-dn.net/?f=1.663%5Ctimes%2010%5E%7B30%7D%5C%20gm)
Step-by-step explanation:
Given
Population of dust particle doubles every 30 minutes
If the initial sample is 21 grams
The model to predict the population will be
![\Rightarrow P=21\cdot 2^{2t}](https://tex.z-dn.net/?f=%5CRightarrow%20P%3D21%5Ccdot%202%5E%7B2t%7D)
Where t=time in hours
A day has 24 hours . So, for 2 days time is 48 hours
Population is given by
Answer:
ion know but bye
Step-by-step explanation:
0.25q + 0.1d = 4.95
d = 3q
0.25q + 0.1(3q) = 4.95
0.25q + 0.3q = 4.95
<u>0.55q</u> = <u>4.95</u>
0.55 0.55
q = 9
0.25(9) + 0.1d = 4.95
2.25 + 0.1d = 4.95
<u>- 2.25 - 2.25</u>
<u>0.1d</u> = <u>2.7</u>
0.1 0.1
d = 27
