case N 1)
we know that
therefore
the answer case N 1) is
case N 2)
we know that
therefore
the answer case N 2) is
case N 3)
we know that
therefore
the answer case N 3) is
13,050,000=1.3x10^7
135,000,000,000,000=1.35x10^14
By arranging the chairs in a 13x13 grid, it can achieve an equal number of rows and columns.
To divide the 169 chairs in the gymnasium into an equal amount of rows and columns, we need to find two factors of 169 that are as close to each other as possible.
The factors of 169 are 1, 13, and 169.
The closest factors are 13 and 13, which means we can arrange the chairs in 13 rows and 13 columns to have an equal amount of chairs in each row and column.
Thus, by arranging the chairs in a 13x13 grid, it can achieve an equal number of rows and columns.

The line which represents the direct variation equation y = 1/2 x is: line c.
We know that every straight line has the equation
y = (slope) x + (y-intercept) .
Here, we have, this line y = 1/2 x,
the equation doesn't show any y-intercept.
The y-intercept is zero,
meaning that the line crosses the y-axis at the place where y=0.
That's the origin where the x- and y-axes cross.
so, we get, the line goes through the origin.
from the given graph we get,
There are only two lines there that go through the origin,
so one of those is the answer to the question.
Now, we have to find the slope of a line.
we know that,
If the slope of a line is positive, that means it rises as it goes.
If the slope of a line is negative, that means it falls as it goes.
The equation of the line is [ y = 1/2 x ].
The slope is 1/2 .
That's positive.
The line on the graph slopes up.
so, we get,
In the picture, that can only be line 'c' .
Hence, The line which represents the direct variation equation y = 1/2 x is: line c.
