I need help with rational and irrational numbers here is the question.
4vir4ik [10]

Answer:

The correct answer choices are:

1) It is a real number

2) It is an irrational number

Step-by-step explanation:

So we have the number:

\sqrt2

First, let's define each of the terms:

Real numbers are all of the irrational and rational numbers. If a number is irrational or rational, then they are a real number. Any number that does not include the imaginary number i is real (you'll learn this eventually. It's actually really interesting!).

Irrational numbers are the numbers that do not terminate nor repeat. Examples include π or √3. Note that numbers like 1/3 which is .3333 is <em>not </em>irrational because they are repeating. π, on the other hand, does not repeat and never ends.

Rational numbers are the numbers that terminate or repeat. They also include the integers, whole numbers, and natural numbers.

So, the √2. First, it's real because it doesn't deal with imaginaries.

Next, use a calculator and calculate √2. We can see that it is about 1.41423562... This number does not repeat. And it does not terminate (end). In other words, √2 is a irrational numbers.

Since it is irrational, it cannot be rational. Since it's not rational, it cannot be an integer, whole number, or a natural number.

Therefore, the correct answer choices are:

1) It is a real number

2) It is an irrational number

El precio de un ordenador portátil ha aumentado un 25% y posteriormente fue rebajado un cierto porcentaje.Calcule que porcentaje
ZanzabumX [31]

Answer:

Se requiere un 20 por ciento de descuento.

Step-by-step explanation:

(This exercise has been presented in Spanish and for that reason explanation will be held in the same language)

Sea p_{o} el precio original del computador portatil, el nuevo precio es:

p_{1} =\left(\frac{100\,\% + 25\,\%}{100\,\%} \right)\cdot p_{o}

p_{1} = 1.25\cdot p_{o}

Si p_{2} = p_{o}, entonces el porcentaje requerido para recuperar el precio original es:

r = \left(1-\frac{p_{2}}{p_{1}} \right)\times 100\,\%

r = \left(1-\frac{p_{o}}{1.25\cdot p_{o}} \right)\times 100\,\%

r = \left(1-\frac{1}{1.25} \right)\times 100\,\%

r = 20\,\%

Se requiere un 20 por ciento de descuento.

In a list of numbers, the pattern increases by 0.001 as you move to the right. If the third number in the list is 0.064, what is
avanturin [10]

The <em>correct answer</em> is:


The first number is 0.062.


Explanation:


Let x represent the first number in the list.


We add 0.001 to each number to find the next number; this gives us:

x + 0.001 + 0.001 = 0.064


Combining like terms, we have:

x + 0.002 = 0.064


Subtract 0.002 from each side:

x + 0.002 - 0.002 = 0.064 - 0.002

x = 0.062
