How many ways can 54,625 be written in expanded form
forsale [732]
In the number 54, 625 from left to right:

5 represents 5,
2 represents 20
6 represents 600
4 represents 4000
5 represents 50,000


so 
<span>
54,625=50,000+4,000+600+20+5=5*10,000+4*1000+6*100+2*10+5


another way we can write this number is </span>5.10^4+4.10^3+6.10^2+2.10+5


Answer:
i) 5*10,000+4*1000+6*100+2*10+5
ii) 5.10^4+4.10^3+6.10^2+2.10+5

2 ways, which are essentially the same thing.

Given the point (3, 3.5), name a second point so that the two points form a horizontal segment.
Sati [7]

For the horizontal segment, the value of the ordinate will not change. Then the second point will be (x, 3.5).

<h3>What is coordinate geometry?</h3>

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

The point is given as (3, 3.5).

Then name a second point so that the two points form a horizontal segment.

For the horizontal segment, the value of the ordinate will not change.

Let x be the abscissa.

Then the point will be given as (x, 3.5).

More about the coordinate geometry link is given below.
