Answer: 1230
Step-by-step explanation: 22 hours that's how much she will be studying in total till the seventh day
and 105 mins till the seventh day
so she will be studying 1230 in total so put 1230 at the blank
1230 is your answer
Well 36 divided by 6 is 6 so multiply that by two and you get 12 14 divided by 6 is 2.3 round that to 2 and multiply it by 2 you get 4 4 +12 is 16 so 16 should be your answer
Answer:
20 units
Step-by-step explanation:
Initial particle concentration = 80 units
Particles removed each hour = 50% of the remaining particles
To find:
Particle concentration after 2 hours = ?
Solution:
Particles removed in 1 hour = 50% of remaining particles
i.e. Particles removed in 1 hour = 50% of initial concentration
Particles removed in 1 hour = 50% of 80 = 40
Particles removed in next 1 hour = 50% of remaining particles
i.e. Particles removed in next 1 hour = 50% of concentration after 1 hour
Particles removed in next 1 hour = 50% of 40 = 20
Total particles concentration removed in 2 hours = 40 + 20 = 60 units
Therefore, particle concentration after 2 hours = Initial concentration - Total particle concentration removed in 2 hours
= 80 - 60 = <em>20 units</em>
