Step-by-step explanation:
1 min = 60 sec
Boxes both can fold per min = 30 + 20 = 50
No of boxes to fold = 200
Time taken in sec = 200 ÷ 50 = 4 min = 60 x 4 = 240 sec
A perfect number is a number where the sum of its divisors is equal to the number.
For example 6: 1 + 2 + 3 = 6
Another example is 28: 1 + 2 + 4 + 7 + 14 = 28
Here is a short list of perfect numbers: 6, 28, 496, 8128, <span>33550336, and the numbers get way bigger as we go on.</span>
I believe the answer 30,164.4
you multiply 19.95 by 3 and you get 59.85
then you figure out how many hours are from 9 am to 9 pm which was 12 then you multiply that by 6 then you take 59.85 and multiply that by 72 then you multiply that by 7
What I meant was, which ones do you need and could you take a picture in better lighting? I can't see it all the way.
