Answer:

x = 185

Step-by-step explanation:

Given:

Plan A

Fixed cost = $14.80

variable cost = 10 cents per min = $0.1 per minute

Plan B

Fixed cost = $18.50

variable cost = 8 cents per min = $0.08 per minute

Computation:

Assume

Plan A cost = Plan B cost

14.80 + 0.1x = 18.50 + 0.08x

x = 185

shutvik [7]

Answer:

On multiplying the equation by 100 we will get 12-x

Step-by-step explanation:

Given data in the question:-

0.03(4-x)

We have to multiply the equation by 100.

Solution:-        

We can write 0.03 as 3/100

(3/100)(4-x)*100\\3(4-x)\\12-x

Circle A has a radius of 9 centimeters and Circle B has a diameter of 19 centimeters. What is the relationship between the circu
IRISSAK [1]

Answer:

18:19

Step-by-step explanation:

Given that,

The radius of circle A = 9 cm

The diameter of circle B = 19 cm

We know that,

Radius = diameter/2

The radius of circle B = 19/2 cm

The circumference of circle A is :

C_A=2\pi r_A ....(1)

And that of circle B is :

C_B=2\pi r_B ....(2)

Dividing equation (1) and (2) :

\dfrac{C_A}{C_B}=\dfrac{2\pi r_A}{2\pi r_B}\\\\=\dfrac{r_A}{r_B}\\\\=\dfrac{9}{\dfrac{19}{2}}\\\\\dfrac{C_A}{C_B}=\dfrac{18}{19}

Hence, the ratio of circumferences of Circle A and Circle B is 18:19.
