Answer:

All terminating and repeating decimals are not rational numbers. For example, pi is a non-terminating & irrational number.

Step-by-step explanation:

The given statement "Are all terminating and repeating decimals rational numbers? Expla" is true.

Yes, all terminating and repeating decimals are rational numbers. A

rational number is defined as any number that can be expressed as a ratio of two integers, with the denominator not equal to zero.

Terminating decimals are those decimals that end after a finite number of digits.

For example, 0.75 is a terminating decimal because it ends after two digits. To show that such decimals are rational,

We can rewrite the decimal as a fraction.

0.75 can be expressed as 75/100 or simplified to 3/4.

Since both the numerator and denominator are integers, 0.75 is a rational number.

Now

Repeating decimals are those decimals that have a repeating pattern of digits after the decimal point.

For example, 0.3333... is a repeating decimal because the digit 3 repeats infinitely.

To show that repeating decimals are rational, we can use a similar approach to terminating decimals.

Take 0.3333... as an example.

We can represent this decimal as an infinite series:

0.3333... = 3/10¹ + 3/10² + 3/10³+ ...

This can be simplified using the formula for the sum of an infinite geometric series:

0.3333... = 3/10¹ + 3/10² + 3/10³+ ...

               = (3/10)/( 1 - 1/10)               (by sum of infinite geometric serires)

               = 3/9

Since 3/9 can be simplified to 1/3, we can conclude that 0.3333... is a rational number.

Thus, all terminating and repeating decimals are rational numbers because they can be expressed as a ratio of two integers.

Answer:

There should be 3 quarters

Step-by-step explanation:

here's why....40 dimes is 4.00 plus 3 quarters is 4.75

The required number of quarters is given as 5, as of the given conditions.

Given that,
There are 40 dimes and quarters in a drawer. The total amount of the coins is $4.75.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
let the number of dimes be d and the number of quarters be q,
According to the question,
d + q = 40 - - - - - (1)
0.10d + 0.25q = 4.75  - - - - - (2)
From equation 1 substitute x in equation 2
0.10[40 - q] + 0.25q = 4.75
4 - 0.10q + 0.25q = 4.75
0.15q = 0.75
q = 5
Out q in the equaiton 1,
d + 5 = 40
d = 35

Thus, the required number of quarters is given as 5, as of the given conditions.

Answer:

2 m

Step-by-step explanation:

The length and width of a rectangular garden is 10 m and 3 m respectively.

He will double the area of the garden by adding the same number of meters to both the length and the width. Area = 2(10 × 3) = 60 m².

Let x is amount of increase in the length and width such that area will be :

(10+x)(3+x) =60

30+10x+3x+x² = 60

x²+13x-30=0

x²+15x-2x-30=0

x(x+15)-2(x+15)=0

x=2 and x = -15

Neglecting negative value, he aded 2 m toboth length and width of the garden.

Answer:

The temperature on Celsius scale for 86 ºF is 30 ºC.

Step-by-step explanation:

Both degrees Celsius and Fahrenheit are relative scales of temperature. The relationship between degrees Fahrenheit and degrees Celsius is summarized by the equation below:

[tex]T_{C} = \frac{5}{9}\cdot (T_{F}-32)[/tex] (1)

Where:

[tex]T_{F}[/tex] - Temperature, measured in degrees Fahrenheit.

[tex]T_{C}[/tex] - Temperature, measured in degrees Celsius.

If we know that [tex]T_{F} = 86\,^{\circ}F[/tex], then its equivalent temperature on Celsius scale is:

[tex]T_{C} = \frac{5}{9}\cdot (86-32)[/tex]

[tex]T_{C} = 30\,^{\circ}C[/tex]

The temperature on Celsius scale for 86 ºF is 30 ºC.

Answer:

There are 7 teams in the league

Step-by-step explanation:

Given that the number of games is given by:

[tex]G(n) = \frac{(n^2-n)}{2}[/tex]

The equation will be used to determine the number of games. As we already know, that 21 games are scheduled which means G(n) is 21 so we have to find n when G(n) is 21

Putting this mathematically

[tex]21 = \frac{n^2-n}{2}[/tex]

Multiplying equation by 2

[tex]2*21 = 2*\frac{n^2-n}{2}\\42 = n^2-n\\n^2-n-42 = 0\\n^2-7n+6n-42 = 0\\n(n-7)+6(n-7) = 0\\(n-7)(n+6)=0\\n-7 = 0 => n=7\\n+6=0 => n=-6[/tex]

As the number of teams cannot be negative, the number of teams in league are 7.

Hence,

There are 7 teams in the league

Step-by-step explanation:

Given that:

At 0 seconds, the video had already played 190 frames and there are 25 frames being played per second.

When the time is equal to [tex]3 \dfrac{2}{5}[/tex], the number of frames that are already being played is:

The length of the rectangle is given by the equation L = 4.5 cm

The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.

Perimeter P of rectangle = 2 ( Length + Width )

Given data ,

Let the perimeter of the rectangle be represented as P = 15 cm

Now , the equation will be

Let the length of the rectangle be L

Let the width of the rectangle be W

Now , width of a rectangle is two-thirds of the length

Substituting the values in the equation , we get

W = ( 2/3 ) L

And , Perimeter P of rectangle = 2 ( Length + Width )

Substituting the values in the equation , we get

15 = 2 ( L + ( 2/3 ) L )

On simplifying the equation , we get

15/2 = L + ( 2/3 )L

15/2 = 5L/3

15 = 10L/3

Multiply by 3 on both sides of the equation , we get

45 = 10L

Divide by 10 on both sides of the equation , we get

L = 4.5 cm

Therefore , the value of L is 4.5 cm

Hence , the length of the rectangle is 4.5 cm

Answer:

A is the correct answer.

Step-by-step explanation:

Answer:

Both equations are same

Step-by-step explanation:

The reason why this is true is not far fetched

looking at the first equation, we have;

3-x = 4

we can also factorize the second equation to look this way

By this, we shall be having

3(4) = 3(3-x)

By the time we take out the 3 from both sides, we will have the initial equation

So what we are saying is that both equations are the same
