She can not fit more than twenty rows in the class so anything equal to twenty or less (not including zero or negative numbers) would be fine. We don't have a limit for how many chairs in a row so I'm answering assuming that is not a problem so 20,19,18,17,16,15,14,13,12,11,10,9,8,7,6,5,4,3,2, or 1 row(s) would be possible
Answer:
So in scientific form 4000 miles will be equal to 
Step-by-step explanation:
We have given that radius of earth is 4000 miles
4000 miles can be written as 4×1000
We have to written 4000 miles in scientific form
We know that 1000 can be written in scientific form as 
So 
So in scientific form 4000 miles will be equal to
<span>Let the width of the rectangular plot of land be 'x' yards.
Given that the length of the rectangular plot of land is 10 yards more than its width.
So, width of the rectangular plot of land = (x + 10) yards.
Also given that the area of the rectangular plot of land is 600 square yards.
We know that, area of a rectangle = length * width
That is, (x+10) * x = 600
x^2 + 10x = 600
x^2 + 10x - 600 = 0
x^2 + 30x - 20x -600 = 0
x(x + 30) - 20(x + 30) = 0
(x +30)(x -20) =0
Therefore, either (x + 30) = 0 or (x - 20) = 0
If x + 30 = 0, then x = -30 and
If x - 20 = 0, then x = 20
Since 'x' represents the width of a rectangular plot of land it cannot be negative.
Therefore,
width of the rectangular plot of land = 20 yards
length of the rectangular plot of land= x + 10 = 30 yards</span>
Check the picture below, that's the "inscribed angle theorem"
Answer:
Step-by-step explanation:
The range would only include positive integers.
