Answer:
1007
Step-by-step explanation:
Divide the expression by two parts: the first one with all positive integer (the integer which can't be divided by two), 1+3+5+...2013 and the rest -2-4-6-...-2012
If you notice both parts are arithmetical sequences
Explore the first one 1+3+5...+2013
a1=1 d=3-1=2 an=2013
a1+d(n-1)=an
1+2(n-1)=2013
2(n-1)=2012
n-1=1006
n=1007
Sn=( 1/2)*(a1+an)*n= 0.5*2014*1007=1007*1007=1014049
-2+(-4)-...-2012
a1=-2
d=a2-a1= -4-(-2)=-2
a1+d(n-1)=an
-2+(-2)(n-1)=-2012
n=1006
Sn= (a1+an)/2*n=(-2-2012)/2*1006=-1007*1006
-1007*1006+1007*1007= 1007- the answer
The second mean
1-2=-1
3-4=-1
5-6=-1
There are 2012/2=1006 couples and every of them has sum -1
-1*1006=-1006
-1006+2013=1007

Given the directed line segment AB: Point A is the _____ with coordinates Point B is the point with coordinates ______.
In the given line segment, the coordinates of Point A and Point B is (1, 3) and (4, 6).
What is a line segment?A line segment in geometry is a section of a straight line that is enclosed by two clearly defined endpoints and contains all of the points on the line that lies inside those endpoints. The Euclidean distance between two ends of a line segment determines its length. A square, for instance, is a two-dimensional geometry with four equal-length sides. In a square, all four interior angles are right angles, and the opposing sides are parallel to one another.So, according to the given image:
Coordinates of point A: (1, 3)Coordinates of point B: (4, 6)Then, Point B is the point with coordinates (4, 6), while Point A is the line (1, 3).
Therefore, in the given line segment, the coordinates of Point A and Point B is (1, 3) and (4, 6).

luke has $1.40 in quarters and nickels. he has 2 more quarters than nickels. how many coins of each type does he have?
Answer:
3 nickels and 5 quarters
Step-by-step explanation:
Let n = number of nickels
q = number of quarters
q = n+2
.25q + .05n = 1.40
Using the first equation and replacing q in the second equation
.25( n+2) + .05n = 1.40
Distribute
.25n+.50 +.05n = 1.40
Combine like terms
.30n +.5 = 1.40
Subtract .5 from each side
.3n +.5-.5 = 1.40-.4
.3n = .9
Divide by .3
.3n/.3 = .9/.3
n = 3
q = n+2
q=5
Step-by-step explanation:
Let the
Nickel coin = x
Quarter coin = y
y = n + 2
0.25y + 0.05x = 1.4
0.25(x + 2) + 0.05x = 1.4
0.25x + 0.5 + 0.05x = 1.4
0.25x + 0.05x = 1.4 - 0.5
0.30x = 0.9
x = 0.9/0.3
x = 3
y = 3 + 2 = 5

Solve for the value of r
Answer:
r = 15
Step-by-step explanation:
These angles are supplementary which means they add up to 180:
6r - 4 + 94 = 180
6r + 90 = 180
6r = 180 - 90
6r = 90

harold licorice company made 6,429.4 feet of licorice in 9 days. to the nearest hundredth of a foot how many feet of licorice on average did the company make per day
Answer: 714.4
Step-by-step explanation: It says the company had made 6,429.4 feet of licorice in 9 days and you want to find the average amount made in 1 day. So what you would do is divide 6,429.4 by 9 and get 714.3777777 so on. Next its says by the nearest hundredths place meaning the 2nd placement after the dot, so what you would do is round it and you get 714.4.

9514 1404 393
Answer:
A. 2
Step-by-step explanation:
When you don't know if a number like 256 is a power of anything, it can work reasonably well to start by simply dividing by the factors you know.
256/2 = 128128/2 = 6464/2 = 3232/2 = 1616 = 2^4, so 256 = 2^4 · 2 · 2 · 2 · 2 = 2^8The 8th root of 2^8 is 2, choice A.
