Answer: 
Step-by-step explanation:
Let d be the distance from Nadia's home to the grocery store.
Given : Nadia traveled uphill to the grocery store for 30 minutes at just 4 mph.
∵ 1 hour = 60 minutes.
Then, 
Since 
Then, 
Also, She then traveled back home along the same path downhill at a speed of 12 mph.
Then, Time taken to travel back home = 
Average Speed =

Hence, her average speed for the entire trip from home to the grocery store and back = 
So to get this the easiest way would be to:
-put 90,000,000 over 186,000 and cancel out zeroes so you have 90,000 divided by 186 ( so it makes more sense in long division later)
-Then divide 90,000 by 186
-get 483.87 seconds
Hope this helped!

Answer:
The new coordinate of the image will be (4, 0) when the point (-4,0) is rotated 180 degrees counterclockwise using center (0,0).
i.e. [(-4,0)→(4,0)]
Step-by-step explanation:
The rule for rotation a point 180° counterclockwise about the origin states that when a point (x, y) is rotated 180° counterclockwise about the origin, the new position of the coordinates of point P(x, y) becomes (-x, -y).
Hence,
- Rotate (x, y) counterclockwise 180° about the origin: [(x,y)→(-x,-y)]
So, when the given point (-4,0) is rotated 180 degrees counterclockwise using center (0,0), the new coordinates of the image will be:
- Rotate (-4, 0) counterclockwise 180° about the origin: [(-4,0)→(4,0)]
Therefore, the new coordinate of the image will be (4, 0) when the point (-4,0) is rotated 180 degrees counterclockwise using center (0,0).
i.e. [(-4,0)→(4,0)]
