Write a power that has a value greater than 140 and less than 145.

Answers

Answer:

$12^(2)$

Step-by-step explanation:

To find: a power that has a value greater than 140 and less than 145

Solution:

Take $x=12^(2)$

Here,

$12^(2)=144$ and $140<144<145$

That is $140<x<145$

Therefore,

$12^(2)$ has a value greater than 140 and less than 145.

Which fraction is equal to 0.4 repeating

Answers

The fraction equal to 0.4 repeating is 4/9.

The fraction equal to 0.4 repeating can be determined by converting the repeating decimal into a fraction form.

We denote the repeating decimal as x. To eliminate the repeating part, we multiply both sides of the equation by a power of 10 that is equal to the number of repeating digits.

In this case, multiplying by 10 will be enough.

10x = 4.44444...

Now, subtracting x from both sides, we have:

10x - x = (4.44444...) - (0.44444...)

9x = 4

Dividing both sides by 9:

x = 4/9

Therefore, the required fraction is 4/9.
