Answer:
357 minutes
Step-by-step explanation:
I subtracted 9 cents/minute from the 23 cents/minute to get 14 cents to get the difference between the two per minute charges. I then divided the monthly cost of $49.95 by .14 to get 356.79... So if you used 357 minutes in a month, the second plan would be 3 cents cheaper at $82.08 (.09 x 357= 32.13 + 49.95), vs. the first plan costing $82.11 (.23 x 357). At 356 minutes the first plan would still be cheaper.
Answer:
700,000
Step-by-step explanation:
To explain this, we need to know the basics.
If you look at the number 790,390, you should automatically know that you can also write the same number as:
700,000 + 90,000 + 300 + 90
How did we do this?
Because each number in 790,390 has a <u>value.</u>
In fact, we can do this for any number! Like this:
12,345
You can also write the same number like this:
10,000 + 2,000 + 300 + 40 + 5
Back to the original question. If there is a seven in the hundred thousands place, that means that the 9 is equal to 700,000
Examples:
12,345
The 3 in this number stands for 300, since it is in the hundreds place.
678,900
The 7 in this number stands for 70,000 because it is in the ten thousands place
Now you know!
(1.3X10^6ft/hr)(2.8X10^3hr)
(1.3*2.8)(10^6*10^3)
Rule (a^b)(a^c)=a^(b+c)
(3.64)(10^(6+3))
3.64(10^9)
3.64X10^9 ft
Technically we only had two significant figures and the answer should be:
3.6X10^9 if we were to express our answer to the correct number of significant figures....
