Answer:
12:30 PM
Step-by-step explanation:
The capacity of pond= 3600 gallon
The Burt is started at 8:30 AM and filled 1800 gallons till 10:30 AM
So, in 2 hours the Burt had filled 1800 gallons.
So, rate of filling = 1800/2=900 gallon/hour
The remaining volume of the pond = 3600-1800 = 1800 gallons
Time to fill the remaining volume = 1800/900=2 hour.
So, it will take 2 hours after 10:30 AM to fill the pond completely.
Hence. the pond will be filled at 12:30 PM.
Answer:
6500
Step-by-step explanation:
In 24 hours, there are 12 times 2 hours, so the bacteria count will increase by 500 twelve times. That is, the increase after 24 hours will be ...
12 × 500 = 6000 . . . bacteria
Since the starting number was 500, the total will be ...
500 + 6000 = 6500 . . . . bacteria after 24 hours
_____
If you like, you can compute the rate of change as 500 bacteria / (2 hours) = 250 bacteria/hour. Then the equation for the number is ...
bacteria = 500 + 250h . . . . . where h is the number of hours.
Filling in h=24, we get
bacteria = 500 + 250(24) = 500 +6000 = 6500 . . . . after 24 hours
Yeah I think it is True cause make sence
First, you must combine all like terms.
'5y' and a '-y' account to a positive '4y'.
7=4y-13
add 13 to both sides to cancel out the -13 on the right side of the equation. we're left with:
20=4y
you must divide by 4 on both sides to get 1y by itself, to know its value. we do so and we get,
y= 5
hope that helped. (:
