Final answer:
The listed conversions between standard and scientific notation are mostly correct, with corrections provided for the representations of 900,000 and 100. Scientific notation involves expressing numbers as a decimal between 1 and 10 multiplied by a power of 10.
Explanation:
The conversions between standard notation and scientific notation provided here mostly appear to be correct, however, there are a few errors:
9) 900,000 in scientific notation would be 9 x 105, not 9 x 10-5.
7) 100 in scientific notation would be 1 x 102, not 1 x 103.
Standard notation is a straightforward representation of numbers. Scientific notation, on the other hand, is a method of writing or displaying numbers in terms of a decimal number between 1 and 10, multiplied by a power of 10.

Given:
A pilot can travel 450 miles with the wind in the same amount of time as 360 miles against the wind.
Pilot's speed in still air is 315 miles per hour.
To find:
The speed of the wind.
Solution:
Let the speed of wind be x miles per hour.
Speed with wind = 315+x miles per hour
Speed against wind = 315-x miles per hour
We know that,
According to the question,
Divide both sides by 90.
By cross multiplication, we get
Divide both sides by 9.
Therefore, the speed of wind is 35 miles per hour.
Final answer:
The speed of the wind is calculated using uniform motion equations for when the pilot is traveling with the wind and against the wind is w = 45 mph,
Explanation:
This is a problem that involves uniform motion, often taught in high school algebra. Let's denote the speed of the wind as w. Since the time it takes for the pilot to travel 450 miles with the wind is the same as the time it takes for them to travel 360 miles against the wind, we can establish two equations which both equal to time (distance/speed).
With the wind: 450/(315+w) = time
Against the wind: 360/(315-w) = time
As both sides equal to 'time', we can equate them together:
450/(315+w) = 360/(315-w)
Solving this equation, we find that w = 45 mph, which is the speed of the wind.

First you have to subtract 2/5 on both sides to get p=2/5x+3/5p.
Then subtract 3/5p on both sides to get 2/5p=2/5.
Then you divide by 2/5 on both sides to isolate p and you get 1 :)

Answer:
43cm
Step-by-step explanation:
Given
Length of Log = 291cm
First Piece = 67cm
Second Piece = 181cm
Required
Determine the length of the third piece
Given that the log was cut into three;
this implies that;
Length of Log = First Piece + Second Piece + Third Piece
Substitute values for first piece, second piece and length of log;
Subtract both sides by 248
Hence, the length of the third piece is 43cm
