Find the sum of the first 2,000 positive integers (the numbers 1 through 2000).

Mathematics
1 answer:
MAVERICK [17]3 years ago
6 0

According to Gauss, the formula to find the sum of a series is:

S=n(n+1)/2 where n is the number of terms in the series

Since n=2000, then:

S=2000(2000+1)/2

S=4002000/2

S=2001000

The famous mathematician Gauss had used this same method to find the sum of the digits 1 to 100 while in elementary school. So the sum of the first 2000 positive integers is 2,001,000

azamat
To find the x coordinate of the midpoint, add the x coordinates and divide by 2
(-5+3)/2 = -2/2 = -1
To find the y coordinate of the midpoint, add the y coordinates and divide by 2
(3+-1)/2 = 2/2 = 1

If 43 of the 148 reams of paper purchased by a department are used, what is the percentage that remains?
Wewaii [24]
100%/x%=148/43
<span>(100/x)*x=(148/43)*x       - </span>we multiply both sides of the equation by x
<span>100=3.44186046512*x       - </span>we divide both sides of the equation by (3.44186046512) to get x
<span>100/3.44186046512=x </span>
<span>29.0540540541=x </span>
<span>x=29.0540540541

</span>now we have: 
<span>43 is 29.0540540541% of 148</span>
