Are rational numbers always, sometimes or never natural numbers?

Mathematics
1 answer:
Delvig [45]4 years ago

Rational numbers are sometimes natural numbers. For example, the number 1 is both a rational and natural number. Remember that natural numbers are 1, 2, 3, 4.. etc. Rational numbers are any number that can be expressed as a ratio of 2 integers. 1/1 is rational.

Most rational numbers, however, are not natural. For example, 3/4, 89/88, and so on.

How do I do this??? It's for my algebra test on Wednesday.

Hold up.  Hee haw.  Whoa!
Your first instinct was to multiply it out and get rid of the parentheses. 
That's often a good instinct, but this time, it made things harder for you.

This is a good example of a rule you should consider: 

         Before you do anything to anything, sit back, relax,
         LOOK at
the problem, THINK about it, and plan your
         strategy.  Decide what the solution might
look like,
         and what you're going to do to the given information
         in order to move towards the solution.


You might look at this particular equation and ponder:

-- If I multiplied this thing out and got rid of the parentheses, it would
have x³ in it.  So there are going to be 3 solutions.

-- If either factor is zero, then the equation is true.

-- One of the factors is 6x.  Setting that to zero gives one solution: x=0.

-- The other two solutions come from setting   (4x² - 4) = 0 .

-- That's the difference of 2 squares, so it's    (2x + 2) (2x - 2) = 0

-- The other 2 solutions come from setting each of those factors to zero.

There you are.  You got this far just by thinking, without even picking up
your pencil yet.

If sin²(32°) + cos²(M) = 1, then what does M equal
Neko [114]

Answer:

M = 32°

Step-by-step explanation:

This is a trigonometric identity, that is

sin²x + cos²x = 1

where x in both cases is the same angle, thus

sin²32° + cos²32° = 1

Hence M = 32°

Simplify 3(x-4)+8(x+2) A) 11x-4 B)11x+4 C)11x-2
swat32
It is depending upon multiplication of values to variable and values of numbers again. Here the answer is Option B) 11x + 4. Here is my process on this equating expression.

For this we have to apply the law of distribution or the distributive law, in this we distribute the parentheses into the brackets to further expand them, we further eliminate the bracketed groups and perform the calculations. So, it is stating that, for any number, variable or a quantity if multiplied into a bracketed expression yields two products of multiplication of two quantities; one being the first quantity outside the brackets and two separately distinguished quantities inside the brackets. They are furthermore subtracted by the first quantity to that of the second quantity to obtain and achieve the distributive law.

If I were to express it through mathematical LaTeX Expressions, it will be represented as the first quantity as a variable of "a" where it can exhibit a value or a variable or a term or rule, etc. and then inside the brackets represented as "b" and "c".

Performing the law of distribution of values, variables, etc. It is demonstrated as:

\boxed{\mathbf{a \times (b - c) = a \times b - a \times c}}

We are given the values of the variables as a separate context and addition of two expressions. So, for both of them:

\mathbf{First \: \: Expression: \: 3 (x - 4)}

\mathbf{Second \: \: Expression: \: 8 (x + 2)}

Apply the following distribution law to expand the values onto variables and numbered values inside the brackets.

So, the variable "a", "b" and "c"; For First Expression is: a = 3, b = x and c = 4.

And, Similarly, for the variable of "a", "b" and "c", For Second Expression is: a = 8, b = x and c = 2.

Therefore, According to our distributive law of expanding the components will directly yield us:

\mathbf{3 \times x - 3 \times 4 + 8 \times x + 8 \times 2}

\mathbf{3x - 12 + 8x + 16}

Regroup the terms for a better visualisation and a clearer understanding for similarities between the terms; it makes it more easier to proceed further. So:

\mathbf{3x + 8x - 12 + 16}

All we did, was to separate the variable attached numbered values and shift it on one side; And, separating or shifting the values without variables to the other side.

\mathbf{11x - 12 + 16}

\boxed{\huge{\mathbf{Required \: \: Answer: \: 11x + 4}}}

Hope it helps.

The first jumbo jet was the Boeing 747, which is 70.5 meters long. The wingspan of the 747 is 60 meters. A model 747 has a wings
yanalaym [24]

Answer:

94cm

Step-by-step explanation:

wingspan         length

60 meters        70.5 m

----------------- = ----------------

80 cm                   x

Cross multiply

(60 m)x = (70.5 m)(80 cm)

Solve for x by dividing both sides of equation by 60 m:

x = (70.5 m)(80 cm) / (60 m) = 94 cm

The length of the model is 94 cm.
