9514 1404 393

Answer:

  8

Step-by-step explanation:

The formula for the number of degrees in the sum of the interior angles of an n-sided polygon is ...

  sum of angles = 180°(n -2)

Filling in the given value and solving for n, we get ...

  1080 = 180(n -2)

  6 = n -2 . . . . . . divide by 180

  8 = n . . . . . . . . add 2

The polygon has 8 sides.

The accountant charged $35 for the first hour of work and $23 for each hour after that.He earned a total of$127 how many hours d
dexar [7]

Answer:

He worked a total of 5 hours.

Step-by-step explanation:

The first hour the man makes $35 dollars for the first hour then for the other hours he earns $23 dollars, right? So we start off with 35.

35 = one hour.

35 + 23 = 2 hours .  =  58.

35  + 23 + 23 = 3 hours. =  81.

35 + 23 + 23 + 23 = 4 hours.  =  104.

35 + 23 + 23 + 23 + 23 = 5 hours. =  127.

We were looking for if the man earned $127 dollars how many hours would be be working.


He'd be working 5 hours.

Hope this helps (:

A área de um retângulo é igual a 44, sabendo que as suas medidas são iguais a 4 e (3x+2), calcule a medida do lado maior deste r
jekas [21]

Responda:

11

Explicação passo a passo:

Área do retângulo = comprimento * largura

Dado

Comprimento = 4

Largura = 3x + 2

Área = 44

Substitua na fórmula e obtenha x

44 = 4 (3x + 2)

44 = 12x + 8

12x = 44-8

12x = 36

x = 36/12

x = 3

Obtenha os lados mais longos

Lado mais longo = 3x + 2

Substitua x = 3

Lado mais comprido = 3 (3) + 2

Lado mais comprido = 11

Portanto, a medida do lado mais longo deste retângulo é 11
