In a store, perhaps. People want it to be easy to shop, so it would be best for say, a top ramen package to be the same net weight as all the other top ramen packages. This makes it 1) easy to label and 2) easy to be confident buying, as it is exactly the same as all the others.
Answer:
4560
Step-by-step explanation:
Well, first we need to understand how different time formats (for lack of a better word) are related in terms of seconds.
1 minute has 60 seconds
I hour has 3600 seconds
1 day has 86400 seconds
1 week has 604800 seconds
Now, with this information at hand, you can find out how many seconds are in X minutes or X days or X months or a year (and so on).
As for your question, we know that one minute has 60 seconds therefore 76 minutes will have (76x60) seconds
We will use demonstration of recurrences<span>1) for n=1, 10= 5*1(1+1)=5*2=10, it is just
2) assume that the equation </span>10 + 30 + 60 + ... + 10n = 5n(n + 1) is true, <span>for all positive integers n>=1
</span>3) let's show that the equation<span> is also true for n+1, n>=1
</span><span>10 + 30 + 60 + ... + 10(n+1) = 5(n+1)(n + 2)
</span>let be N=n+1, N is integer because of n+1, so we have
<span>10 + 30 + 60 + ... + 10N = 5N(N+1), it is true according 2)
</span>so the equation<span> is also true for n+1,
</span>finally, 10 + 30 + 60 + ... + 10n = 5n(n + 1) is always true for all positive integers n.
