Which value is equivalent to<br> 3/11?<br> OA A. 0.27<br> O<br> B. 0.27<br> OC<br> C. 3.6<br> OD. 3.
Sladkaya [172]

Answer:

0.27 repeating.

Step-by-step explanation:

So to solve this we just have to use division.

1 clearly doesnt go into 3 at least one time, so we can add a decimal point and add a 0 to make it 30.

11 goes into 30 2 times, so we have:

0.2

and 30-22=8

So we can add another 0 and make it 80.

Then 11 goes into 80 7 times. So we have:

0.27

and 80-77=3

So again, add the 0, we have 30.

11 goes into 30 2 times, so:

0.272

and 30-22=8

Add another 0 we get 80.

11 goes into 80 7 times.

So finally, we have:

0.2727.

This is a repeating decimal.

This can be shown as:

0.<u>27</u>

So this is your answer!

I was a bit confused with which one it was on your answer key, but knowing that it is 0.<u>27</u> I am guessing you can chose!

Hope this helps!

Find the most important variable in the problem.
natali 33 [55]

Answer:

A

Step-by-step explanation:

Let

x = the number of phone available

If it would require 8 more phones, then the total number of phones will be x + 8.

A company hired an additional 12 employees, and every employee needed a phone, then

x + 8 = 12

x = 4

This means 4 phones were available (and 8 more needed to total in 12 phones for 12 new employees)

Hence, correct option is option A.

Solve for x -3x+6=2x-24<br><br>-30<br><br>-6 <br><br>6<br><br>30
Svetach [21]

-3x + 6 = 2x - 24.

Add 3x to both sides.

6 = 5x - 24.

Add 24 to both sides.

30 = 5x.

Divide it all by 5.

<em><u>x = 6.</u></em>

Please explain thank you!
Rus_ich [418]

Answer:

56%

Step-by-step explanation:

To find a percentage, you need to take a ration of the value you want and the total. In this case, 28 is the value and 50 is the total, right? Then, to make it a s

proper percentage, you multiply by 100. As such:

\frac{28}{50}  \times 100 =  \frac{14}{25}  \times 100 = \\  =  14 \times 4 = 56
