Convert the following repeating decimal to a fraction in simplest form .31 with the 1 repeating
bekas [8.4K]

Answer:

14/45

Step-by-step explanation:

So we have the fraction:

0.3\bar1=0.31111...

We can do this algebraically. Follow to following steps:

Let's let this number equal to n. Thus:

0.31111...=n

Since there is only 1 digit repeating, let's multiply everything by 10. So:

3.1111...=10n

Now, subtract n from both sides:

3.1111-n=10n-n

On the left, substitute the number for n. On the right, combine like terms:

3.1111...-0.31111...=9n

All of the 1s will cancel. So:

3.1-0.3=9n

Subtract:

2.8=9n

Divide both sides by 9:

n=2.8/9

Remove the decimal by multiplying both sides by 10:

n=28/90

Reduce:

n=14/45

And we're done!

Use a calculator to check:

14/45\stackrel{\checkmark}{=}0.31111...

Graph the set. in number line<br> (1, ∞) ∩ (−10, ∞)
svlad2 [7]

See attachment for the graph of the set (1, ∞) ∩ (−10, ∞)

<h3>How to graph the set on a number line?</h3>

The set is given as:

(1, ∞) ∩ (−10, ∞)

The above means that the numbers inclusive in the set are numbers between the following set:

  • (1, ∞): All real numbers greater than 1
  • (−10, ∞): All real numbers greater than -10

The intersection of the above set is (1, ∞)

This means that the set (1, ∞) ∩ (−10, ∞) is a set of all real numbers greater than 1

Having done the above illustration, next we plot the set on a number line

See attachment for the graph of the set (1, ∞) ∩ (−10, ∞)

Question 7: 10 pts
levacccp [35]

The teacher ordered the students in 24 ways.

We have given that the total number of students is 4.

4 students are assigned to give presentations.

We have to find the arrangement of the 4 students.

<h3>What is the arrangement?</h3>

An arrangement (or ordering) of a set of objects is called a permutation. (We can also arrange just part of the set of objects.)

In a permutation, the order that we arrange the objects n is important.

4 students can be arranged by 4! ways.

4!=4*3*2*1\\  =12*2\\=24

Therefore option 3 is correct.

The teacher ordered the students in 24 ways.
