Tanzania [10]

If x represents the mass of 1 ball in kg, then the balance shows ...

... 6x = x + 9 kg

... 5x = 9 kg

Then 6x is ...

... (6/5)·5x = (6/5)·9 kg = 10.8 kg

0.8 kg = 0.8·1000 g = 800 g

so 10.8 kg is ...

How can you use a 10-by-10 grid to model 12%? You can shade half of the squares. You can shade half of one row of the squares. Y
TiliK225 [7]

Answer:

The options provided do not have the correct answer. Read below.

Step-by-step explanation:

Given a 10 by 10 grid model means that there are exactly 100 individual squares present. This shows that each square is equal to 1%.

None of the options provided gives us 12% of the model.

The first option results in 50%, the second results in 5%, third option results in 0.5% and the last option results in 2%.

For 12% we can shade 12 squares completely, half of 24 squares etc.

I hope this answer helps.

What is two thirds of eight
AlladinOne [14]
5 + 0.33333... 

<span>If you don't immediately recognize 0.33333.... as 1/3 (a very common fraction you should memorize), you can do the following. </span>

<span>x = 0.33333... </span>

<span>Multiply that by 10 to shift everything 1 place to the left: </span>
<span>10x = 3.33333... </span>

<span>Now subtract: </span>
<span>10x - x = 3.33333... - 0.33333... </span>
<span>9x = 3 </span>
<span>x = 3/9 </span>
<span>x = 1/3 </span>

<span>Answer: </span>
<span>5 1/3 </span>

<span>P.S. Here's a shortcut way to turn a repeating decimal into a fraction. </span>

<span>1) Take the repeated part and put it over an equivalent number of nines. </span>

<span>Example: </span>
<span>0.57575757... = 57/99 </span>

<span>At that point, see if you can reduce the fraction: </span>
<span>= 19/33 </span>

<span>Another example: </span>
<span>0.123123123... = 123/999 </span>
<span>= 41/333 </span>

<span>So in your example: </span>
<span>5.33333... = 5 + 0.33333... </span>
<span>= 5 + 3/9 </span>
<span>= 5 1/3</span>
