how many seconds in 8 hour

The correct answer is: $28800\text{ s}$ Explanation We convert hours to seconds by using minutes and seconds. Steps: One hour in seconds: $$1\text{ h}=60\text{ min}\times60\text{ s/min}=3600\text{ s}$$ Multiply by 8 hours: $$8\text{ h}=8\times3600\text{ s}=28800\text{ s}$$ Final check: $$8\text{ h}=28800\text{ s}$$ Therefore, 8 hours equals $28800\text{ seconds}$.

How many Seconds in Hour

The correct answer is: $3600\text{ s}$ Explanation One hour contains 60 minutes and each minute contains 60 seconds, so you multiply the two. Steps: First step: $1\text{ hour}=60\text{ minutes}$ Second step: $1\text{ minute}=60\text{ seconds}$ Final step: $$60\times60=3600$$ Therefore, there are $3600\text{ s}$ in one hour.

The correct answer is: $6719$ Explanation We subtract 1856 from 8575 by removing thousands, hundreds, tens, and ones step by step. Steps: Subtract the thousands: $$8575 - 1000 = 7575$$ Subtract the hundreds and tens: $$7575 - 800 = 6775$$ then $$6775 - 50 = 6725$$ Subtract the ones: $$6725 - 6 = 6719$$ Therefore, $$8575 - 1856 = 6719.$$

The correct answer is: $1728$ Explanation Subtract by adjusting: $3984$ is $4000-16$, so subtracting it is the same as subtracting $4000$ then adding $16$. Steps: $5712-3984=5712-4000+16$ $5712-4000=1712$ $1712+16=1728$ Therefore, $5712-3984=1728$.
