A self own company charges $40 per month +0.05 cents for each text message sent.Select expression is there a percent of cost in
kondaur [170]
<h3>The monthly cost of cell phone is A  =  40 + 0.005 m</h3>

Step-by-step explanation:

The monthly fixed charges by mobile company = $40

The cost of sending each text message  = 0.05 cents

Now, 100 cents  = 1 dollar

⇒ 1 cent  =$ (\frac{1}{100} )

⇒ 0.05  cent s =$ (\frac{1}{100}  \times 0.05)  =0.0005

Also, the number of text messages send  =  m

So, the cost of sending m text message  = m x ( cost of 1 text )

= m x ( $ 0.0005) = 0.0005 m

Now, Total bill = Fixed rate + cost of m texts

⇒ A  =$40  +  $ 0.0005 m

Hence, the monthly cost of cell phone is A  =  40 + 0.005 m

Each interior angle of a regular polygon is 140°.Find the number of sides​
castortr0y [4]

Step-by-step explanation:

Each interior angle=140°

(n-2)180°/n=140°

180°n-360°/n=140°

180°n-360°=140°n

180°-140°=360°

40°n=360°

n=360°/40°

n=9

Hence, the number of sides of the polygon is 9.

It is nonagon .
