Answer: It can be expressed as

\frac{4}{10}+\frac{4}{100}+\frac{4}{1000}+........

Step-by-step explanation:

Since we have given that 0.44444.......

We need  geometric series that represents as a fraction.

so, it can be written as

0.4+0.04+0.004+0.0004...............

But as we are required to write it as a fraction , So, it becomes,

\frac{4}{10}+\frac{4}{100}+\frac{4}{1000}+\frac{4}{10000}............

and it is a geometric series.

Because it has first term = a = \frac{4}{10}

and common ratio = r = \frac{a_2}{a_1}=\frac{\frac{4}{100}}{\frac{4}{10}}=\frac{1}{10}

Hence, it can be expressed as

\frac{4}{10}+\frac{4}{100}+\frac{4}{1000}+........

How would i calculate 1.9 minus 11/12?
Genrish500 [490]
Step 1) turn 1.9 into an improper fraction.

= 19/10

step 2) find a least common denominator between 10 and 12.

= 60
(10x6 and 12x5)

step 3) convert the fractions so they have the same denominator.

= 19x6 is 114.
10x6= 60.
= 11x5 is 55.
12x5 is 60.
now you have your new fractions.

step 4) subtract.

= 114/60 - 55/60 is 59/60.

step 5) simplify.

the answer is either 0.9833... (3 repeating) or just 59/60 (you can't simplify the fraction any further).

A cable company charges $35 for basic subscription and $4 per premium channel. Write a function rule that represents the money c
vampirchik [111]

Answer:

c = 4x + 35

Step-by-step explanation:

Imagine c = cost

$35 is base price so you add that to whatever else you spend.

Let x = number of channels you buy. ($4/CHANNEL)

so cost is equal to $4*channels plus 35

Therefore

c = 4x+35
