Answer:

$x \leq -\frac{1}{4}$

Step-by-step explanation:

Write it out: -8x ≥ 2
Divide each side by -8 to cancel out the -8 next to x. It should now look like this: $x \leq -\frac{1}{4}$

The number that produces an irrational number when multiplied by 0.4 is 3π. The correct option is A. $3\pi$

To determine which number produces an irrational number when multiplied by 0.4

First and foremost, 0.4 is a rational number.

A rational number is a number that is of the form $\frac{p}{q}$ where p and q are integers and q is not equal to 0.

0.4 can be written as $\frac{4}{10}$ or $\frac{2}{5}$ , hence, it is a rational number.

Now,

Any irrational number when multiplied by a rational number other than zero will also be irrational.

Therefore, we are to determine which of the given options is an irrational number.

For option A. 3π

π is an irrational number, therefore 3π is also an irrational number

For option B. 0.444...

0.444... can be expressed as 4/9, therefore it is a rational number

For option C. $\sqrt{9}$

$\sqrt{9}$ = 3, which can be expressed as 3/1, therefore it is a rational number

For option D. $\frac{2}{7}$

$\frac{2}{7}$ is a rational number

The only irrational number among the given options is 3π

Hence, the number that produces an irrational number when multiplied by 0.4 is 3π. The correct option is A. $3\pi$

Answer:

Okay, I won't give the answers... HOWEVER, I will show you how to get them yourself! :>

Step-by-step explanation:

A triangles area is essentially half of a square. In my math class, we would multiply the main base, and the height and then proceed to break it in half. For example;

TRIANGLE ONE-- 16 x 16 =__ then cut your answer in half
