Answer:

Costo fijo= $104.5

Costo unitario=  $0.5 por minuto

Step-by-step explanation:

Mes pasado:

$239 por 269 minutos

Mes corriente:

$175 por 141 minutos

<u>Primero debemos calcular el cost por minuto de llamada:</u>

Costo unitario= (costo total más alto - costo total más bajo) / (cantidad de minutos más alto - cantidad de minutos más bajo)

Costo unitario= (239 - 175) / (269 - 141)

Costo unitario=  $0.5 por minuto

<u>Ahora, el costo fijo:</u>

Costo fijo= costo total más alto - (costo unitario*cantidad de minutos más alto)

Costo fijo= 239 - (0.5*269)

Costo fijo= $104.5

Costo fijo= costo total más bajo - (costo unitario*cantidad de minutos más bajo)

Costo fijo= 175 - (0.5*141)

Costo fijo= $104.5

A fair die with sides numbered 1, 2, 3, 4, 5, and 6 is to be rolled until a number greater than 4 first appears. what is the pro
AnnyKZ [126]
First two rolls have to be 1-4 that is 2/3 chance twice and the third can be 4or 5
2/3*2/3*1/3 + the chance that the fourth is the 5 or 6. 
2/3*2/3*2/3*1/3

So the solution is : P=2/3*2/3*1/3 + 2/3*2/3*2/3*1/3

1.)A rectangle has an area of 72 square centimeters and the length is twice the width. The perimeter of the rectangle
Greeley [361]

1.

area = L x w = 72

L = 2w

72 = 2w*w = 2w^2

divide by 2

36 = w^2

w = sqrt(36) = 6 

l = 2*6 =12

perimeter = 2L +2W = 2*12 + 2*6 = 24+12 = 36


2.

sqrt(40)= 6.324555 cm ( round to 6.32 )

6.32 - 4 = 2.32 cm original length of a side

If the fraction 414/x-10 is equivalent to -23 ​, find the value of x. Show your work. Use reasoning to find x.
NemiM [27]

Answer:

x = -8

Step-by-step explanation:

Solve for x by getting rid of the fraction.

414/(x-10) = -23

414 = -23(x-10)

414 = -23x + 230

184 = -23x

-8 = x
