9,540,000 in expanded form using exponents to show power of 10
alina1380 [7]
The expanded form of 9,540,000 is:
9,540,000 = 9000,000 + 500000 + 40000 + 000 +00 + 0
we can also write it as :
9,540,000 = 9 x 1000000 + 5 x 100000 + 4 x 10000
and using exponents as power of 10 is:
9,540,000 = 9 x 10⁶ + 5 x 10⁵ + 4 x 10⁴

our goal is to run a mean of 45 minutes per day for a week. For the first six days, you run 38, 40, 40, 42, 43, and 50 minutes.
oksano4ka [1.4K]

Answer:

62 minutes.

Step-by-step explanation:

To find the mean, you need to <u>add</u> together all of your values (the minutes) and <u>divide</u> them by the number of values (how many sets of minutes given).

So, choosing to add 62 minutes:

38 + 40 + 40 + 42 + 43 + 50 + 62 = 315

There are 7 sets of minutes in total, so we then divide 315 by 7.

315/7 = 45 minutes

Therefore, running 62 minutes on the seventh day would cause you to run a mean of 45 minutes per day for the week.
