Maya and Reginald are installing hardwood flooring. Maya can install flooring in a room in 4 hours. Reginald can install flooring in a room in 3 hours. How long would it take them if they worked together?
Answer:
1 hour 42 minutes approx
Step-by-step explanation:
Given data
Mayas work rate= 1/4 room per hour
Reginald work rate= 1/3 room per hour
Let the total time taken for both of them be T
Hence their combined work rate
1/4+1/3= 1/T
3+4/12=1/T
7/12=1/T
T= 12/7
T= 1.7 hours
Hence it will take them 1 hour 42 minutes approx
What is the image of the point (9,7) after a rotation of 180 counterclockwise about the origin
The image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.
Rotation of a point A(x, y) 180 counterclockwise about the origin produces an image at A'(-x, -y).
Hence, the image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)

20N = 360
N = 18
Proof:
(18 x 180) -360 = 2880 total degrees
2880/18 sides = 160°
