and im not trying to read all that, those are a lot of words
I am assuming you are trying to find the sum.
First, plug in n for 1, then n for 80 to get the following numbers:
5/6 and 163/6
As you go up the sequence, as n is increased by 1, then the next number is increased by 1/3
Use the arithmetic sequence formula to solve for the sum.
n * (a1 + a2)/2 where a1 is 1st number and a2 is last number.
80 * (5/6 + 163/6)/2
Simplify the expression to get 1120.
Answer:
7minutes
Step-by-step explanation:
so if 48 books are sorted in 120 seconds what about 168 books if you cross multiply you will get 420 seconds which converted to minutes is 7
1. 2/100 or 1/50, as 0.02 is equal to 2 hundreths. Simplifying gets you 1/50
3. 1/2 or 50/100, as 0.50 is equal to 0.5 which is equal to 50 hundreths. Simplify to get 1/2
5. 88/100 or 44/50 , as 0.88 is equal to 88 hundreths. After simplifying, you get 44/50
Depending on your teacher, you may be told to not simplify. It depends
