Answer:
7.83 * 10^-7
Step-by-step explanation:
In order for the expression to be valid, you have to be working with a whole number, so you take 0.000000783 and make it 7.83
Count the amount of placement you just removed and take 10 and put it to the power of the number of placement you removed (10^7).
In this case you are making the number smaller instead of bigger so the exponent is negative.
If you were making 7.83 into, for example, 70,830,000 then the scientific notation would be 7.83 * 10^7. The exponent would be positive.
Hope this isn't confusing and you can understand it. Have a good day! :)
Answer:
69 users.
Step-by-step explanation:
First, we need to calculate the amount of seconds in one day.
a) Each hour has 60 minutes and each minute has 60 seconds.
Therefore, one hour has (60)(60) = 3600 seconds.
b) Since the day has 24 hours, we are going to multiply the total amount of seconds per hour by 24.
3600 (24) = 86400 seconds per day.
c) Now that we have the amount of seconds per day, we are going to divide the total amount of users added each day by the amount of seconds per day.
6000000/86400 = 69.44 users per second.
Therefore, 69 users are added, on average, each second.
