Find percent increase by subtracting the amounts and dividing it by the old amount, then multiply the result by 100 to make it a percent.
Increase= (277-210)/210
67/210
Then it ends up as 0.319047619...
Multiply that by 100 to make it a percent, which is..
31.9047619..
Round it off, and you get..
32%!

Answer:
9x+2
Step-by-step explanation:
It's a simple problem, to find the perimeter, add a+b+c. In this case, it's with binomials, but it follows the same idea.
(2x+2)+(3x+1)+(4x-1)
2x+2+3x+1+4x-1
Combine like terms.
2x+3x+4x=9x
2+1-1=2
Left with 9x+2 as your perimeter binomial.
Answer: 1 & 1/2
The whole part is 1
The fractional part is 1/2
======================================================
Explanation:
Write 1/2 as 2/4. Basically you multiply top and bottom by 2.
We have these three fractions: 1/4, 2/4, 3/4
Add them up: (1/4)+(2/4)+(3/4) = (1+2+3)/4 = 6/4 = 3/2
To go from 6/4 to 3/2, we divide both parts by 2.
Finally, convert the improper fraction 3/2 to the mixed number 1 & 1/2
Answer:
1,460 hours per year.
113,880 hours in a lifetime.
Step-by-step explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
Let's assume that on an average day Americans drive 4 hours a day. This includes going and coming from work as well as any groceries they might need to do. Since there are 365 days in a year we can multiply this by the hours a day driven.
We can "guesstimate" that on average an American drives 1,460 hours per year.
Based on my research the average lifetime of an American is 78 years old. We can now multiply this by the number of hours driven in a year to have an idea of the number of hours driven in a lifetime.
On average we "guesstimate" that an American drives 113,880 hours in a lifetime.
