How to simplify 0.111111111 repeating as a fraction

2 answers:

6 0

Any numerical repeating pattern can be rationalized...let x=0.111 then:

10x=1.111 and upon taking differences:

10x-x=1.111-0.111

9x=1 then divide both sides by 9

x=1/9

(This method works for converting any repeating numerical pattern to a rational number)

Depending on how many times it repeats, and I used 9 1's from your question, the answer would be 1/9.

Excuse if I have this wrong but I’m going to guess that in every question how the 2 is up the m or the other letters that means you are multiplying that number/ letter by its self one more time so I’m not really sure, I’m sorry.

A small manufacturing firm has 250 employees. Fifty have been employed for less than 5 years and 125 have been with the company

sukhopar [10]

Answer:

Step-by-step explanation:

Given that a small manufacturing firm has 250 employees. Fifty have been employed for less than 5 years and 125 have been with the company for over 10 years. So remaining 75 are between 5 and 10 years.

Suppose that one employee is selected at random from a list of the employees

A) Probability that the selected employee has been with the firm less than 5 years = $\frac{50}{250 } \\= 0.20$

B) Probability that the selected employee has been with the firm between 5 and 10 years

= $\frac{75}{250 } \\= 0.30$

C) Probability that the selected employee has been with the firm more than 10 years

= $\frac{125}{250} =0.50$

a) P(A) = 0.2

P(C) = 0.5

P(A or B) = 0.2+0.3 = 0.5

P(A and C) = 0 (since A and C are disjoint)

Can someone show me how to do it and the answer

Virty [35]

Answer:

Step-by-step explanation:

The equation of a circle is

(x-h)^2 + (y-k)^2 = r^2

h= 9, k = -7

r = 2, so r^2 = 4.

We now know that the equation must equal 4, so we can rule out answers A and C.

Plug in the values for h and k to get

(x-9)^2 + (y+7)^2 = 4

Choice B is correct!
