Answer:
<u>GIVEN :-</u>
Ordered pairs given are :-
- (2 , -1)
- (-5 , 3)
- (4 , 3)
- (-2 , -3.5)
- (0.5 , 1.75)
<u>TO FIND :-</u>
- Correct quadrant for each ordered pair.
<u>FACTS TO KNOW BEFORE SOLVING :-</u>
- While writing the co-ordinates of a point , its ordered pair is always in the form of ( x , y ) where x = x-coordinate of the point & y = y-coordinate of the point.
- In Quadrant 1 , the coordinates of a point is always = ( +x , +y ) because Quadrant 1 lies between the positive side of x-axis & positive side of y-axis.
- In Quadrant 2 , the coordinates of a point is always = ( -x , +y ) because Quadrant 2 lies between the negative side of x-axis & positive side of y-axis.
- In Quadrant 3 , the coordinates of a point is always = ( -x , -y ) because Quadrant 3 lies between the negative side of x-axis & negative side of y-axis.
- In Quadrant 4 , the coordinates of a points is always = ( +x , -y ) because Quadrant 4 lies between the positive side of x-axis & negative side of y-axis.
<u>SOLUTION :-</u>
- (2 , -1) is in <u>Quadrant 4</u> because it's x-coordinate is positive whereas its y-coordinate is negative.
- (-5 , 3) is in <u>Quadrant 2</u> because its x-coordinate is negative but y-coordinate is positive.
- (4 , 3) is in <u>Quadrant 1</u> because both its x-coordinates & y-coordinates are positive.
- (-2 , -3.5) is in <u>Quadrant 3</u> because both its x-coordinates & y-coordinates are negative.
- (0.5 , 1.75) is in <u>Quadrant 1</u> because both its x-coordinates & y-coordinates are positive.

Answer:
Yes.
2 feet
Step-by-step explanation:
Pieces of copper that Arsenio needs in total = 27 pieces
Length of each piece of copper tubing that he needs = 2/9 foot
Length of available tubing = 8 foot
Since, the length of each piece is 2/9 foot, the length of 27 pieces would be:

This means, Arsenio needs 6 feet in total for the copper tubing. Since he got 8 feet in total, he has sufficient amount of tubing available.
After making the 27 pieces, he will be left with 8 - 6 = 2 feet of tubing.
