Answer:

9

Step-by-step explanation:

size of each interior angle can be represented by: 140^{o} = 180^{o}•\frac{(n-2)}{n}

solve for n:

140^{o} = 180^{o}•\frac{(n-2)}{n}                   multiply both sides by n

140ºn = 180º(n - 2)                 distribute 180º to (n - 2)

140ºn = 180ºn - 360º             subtract 180ºn from both sides

-40ºn = -360                          divide both sides by -40º

n = 9

Is there a relationship between area or perimeter of a rectangle
Arturiano [62]
Hello,

For a given perimeter (P) there are an infinity of Area (A)
Let's say x the length, and y the wide of the rectangle

P=2(x+y)
A=xy
k=x-y >=0

As (x+y)²-4xy=(x-y)²: A²-4P=k² or P=(A²-k²)/4
In primus, you will find a graph (abacus) giving P for a A and k given.
Negative Area or P are excluded.(just remind the first quadrant, A>=0 and P>=0)

A repairman estimated the cost of replacing a part in Mrs. James’ computer would be at most $225. The estimate included $35 for
MA_775_DIABLO [31]

Answer:

The maximum number of hours the repairman estimated for the job is 5.

Step-by-step explanation:

It's simple. First, all you have to do is start with the budget he gave you and subtract the fixed price.

225 - 35 - 40 = 150

Then, use the money you have left over (150) and divide by how much he pays per hour which equals 5.

150/30 = 5

Hope this helps! If you have any additional questions please don't hesitate to ask me or your teacher to be sure you master the subject. Stay safe and please mark brainliest!  :)
