Show that each number is a rational number by expressing it as a ratio of two integers

A. 27
B. .075
C. 4 2/3
D. -9
E. 0.43
F. -18

Answers

Final answer:

Each number provided is a rational number, as they can all be expressed as a ratio of two integers. Therefore, they all qualify as rational numbers.

Explanation:

In Mathematics, a rational number is a number that can be expressed as a ratio of two integers. An integer is a whole number that can be positive, negative, or zero. Let's express each number given as a ratio of two integers:

 

A. 27 can be expressed as 27/1. B. 0.075 can be expressed as 75/1000. C. 4  2/3 can be expressed as 14/3 (since 4 2/3 equals to 4 + 2/3 = 12/3 + 2/3 = 14/3). D. -9 can be expressed as -9/1. E. 0.43 can be expressed as 43/100. F. -18 can be expressed as -18/1.

As you can see, each of these numbers can be written as a ratio of two integers, thus they are all rational numbers.

#SPJ11

Each given number (27, 0.075, 4 2/3, -9, 0.43, and -18) is shown to be a rational number by expressing it as a ratio of two integers, such as 27/1, 3/40, 14/3, -9/1, 43/100, and -18/1, respectively.

To show that a number is a rational number, we must express it as a ratio of two integers.

27 can be expressed as 27/1 which is the ratio of two integers (27 and 1).0.075 can be written as 75/1000 which simplifies to 3/40 after dividing both the numerator and the denominator by 25.4 2/3 is 4 + 2/3 and can be written as 14/3 which is a combination of an integer and a fraction representing the ratio of two integers (14 and 3).-9 can be written as -9/1 which shows the number -9 as a ratio of two integers (-9 and 1).0.43 is equivalent to 43/100 and therefore can be expressed as the ratio of two integers (43 and 100).-18 can be written as -18/1 which is a ratio of two integers (-18 and 1).

what is the rate of 2.50/10.50
and 1.99/2.50

Answers

Unsure of what you're asking by "What is the rate of 2.50/10.50
and 1.99/2.50?"  Do you mean, "What is the RATIO of 2.50/10.50
and 1.99/2.50?"

If so, this ratio is 

2.5/10.5
---------------
1.99/2.50

Invert the denominator, obtaining 2.50/1.99, and then multiply the numerator 2.5/10.5 by this result:

2.5        2.5        6.25
------- * ------- = -----------  =  1 / 3.3432, or 0.2991.
10.5      1.99      20.895

If this is not the question you intended to share, please fix up your original post so I'll know what you meant.

Answer: The rate of both are 0.23 and 0.796 respectively.

Step-by-step explanation:

Since we have given that

Rate of 2.50/10.50

We need to find the rate which is given by

[tex]\dfrac{2.50}{10.50}\\\\=0.23[/tex]

Similarly,

Rate of 1.99/2.50

We need to find the rate which is given by

[tex]\dfrac{1.99}{2.50}=0.796[/tex]

Hence, the rate of both are 0.23 and 0.796 respectively.

An acute triangle has sides measuring 10cm and 16 cm. The length of the third side is unknown. Which best describes the range of possible values for the third side of the triangle?

Answers

Answer:

The range of possible values for the length of the third side of the triangle is [tex]\( 6 < x < 26 \)[/tex], meaning that the third side must be greater than 6 cm and less than 26 cm.

Explanation:

To determine the range of possible values for the third side of the triangle, we can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Let's denote the length of the third side as [tex]\( x \)[/tex]. According to the triangle inequality theorem:

1. The sum of the lengths of the two given sides (10 cm and 16 cm) must be greater than the length of the third side:

[tex]\[ 10 + 16 > x \][/tex]

[tex]\[ 26 > x \][/tex]

2. The length of the third side must be greater than the difference of the lengths of the two given sides:

[tex]\[ 16 - 10 < x \][/tex]

[tex]\[ 6 < x \][/tex]

Combining both inequalities, we have:

[tex]\[ 6 < x < 26 \][/tex]

what is 4.1363636… as a fraction?

Answers

I got 1 over 25 because you wanna turn the decimal into a percentage first

Answer:

x = [tex]\frac{819}{598}[/tex].

Step-by-step explanation:

Given  :  4.1363636…

To find : Convert it as fraction .

Solution : We have given   4.1363636…

Let x =   4.1363636…

On multiplying both sides by 100

100 x = 100 *   4.1363636…

100 x = 413 .63636...

We can convert it in term of x

100 x = 409 .5 + 4.1363636...

100 x = 409.5 + x

On subtracting both sides by x

100 x -x = 409.5

99 x = 409. 5

On dividing both sides by 99

x = [tex]\frac{409.5}{99}[/tex].

x =  [tex]\frac{4095}{990}[/tex].

On dividing both sides by 5

x = [tex]\frac{819}{598}[/tex].

Therefore, x = [tex]\frac{819}{598}[/tex].

Answers

I think its 4+(-98=y)
ANSWER

The equation in point-slope form is
[tex]y + 1 = \frac{8}{9} (x + 4).[/tex]


EXPLANATION

The equation of a line in point slope form is given by,


[tex]y-y_1=m(x-x_1)[/tex]

where
[tex]m[/tex]
is the slope and
[tex](x_1,y_1)[/tex]
is any given point on the line.


Let us now find the slope using the point,

[tex](-4,-1) \: and \: (5,7)[/tex]


We apply the slope formula,

[tex]m=\frac{y_2-y_1}{x_2-x_1} [/tex]

This implies that,

[tex]m = \frac{7 - - 1}{5 - - 4} [/tex]


[tex]m = \frac{7 + 1}{5 + 4} [/tex]


[tex]m = \frac{8}{9} [/tex]


The equation is now given by,

[tex]y - - 1 = \frac{8}{9} (x - - 4)[/tex]

Or

[tex]y + 1 = \frac{8}{9} (x + 4)[/tex]

Water weighs 8.34 pounds per gallon. How many ounces per gallon is the weight of the water

Answers

In preparation for the Maths festival you are asked to work out how much water the drinks area will need for the event. The arena buys drinks in 200 litre containers. Each person is expected to drink 0.5 litre of water. The arena expects approximately 7,000 people to attend. Estimate how many containers of water the arena will need to buy for the event?

Answers

We want to know how many people use a 200 liter container. To do that, we do (size of container)/(amount of water people drink)=200/0.5=400 people/container. Next, since we have 1 container / 400 people (1 container = 400 people, so it can go either way) , we want to find how many containers we need for 7000 people. To cross the amount of people out, we multiply the expression by 7000 people to get 7000 containers/400=2.5 containers.

Answer:

Its 18 containers

a number where 3 is worth 1/10 as much and 2 is worth 10 times as much as the number 431, 621

Answers

413,261 now i need to type more so it can be 20 characters
Final answer:

The question pertains to exponential notation in our decimal numbering system, where each place is worth ten times the next right place. It creates a more convenient way to express very large or small numbers. The rules of multiplication in this system involve multiplying the numbers out front and adding the exponents.

Explanation:

The question refers to place value in a number, where we are told how much each digit is worth based on their position. Here, '3' is worth 1/10 as much and '2' is worth 10 times as much as the number 431, 621. The power (exponent) of 10 is equal to the number of places the decimal is shifted to give the digit number.

This is part of exponential notation, which is especially useful for very large and very small numbers. For instance, 1,230,000,000 can be written as 1.23 × 10⁹, and 0.00000000036 can be articulated as 3.6 × 10-¹0. It's called powers-of-ten notation because each place in our numbering system is ten times greater than the place on its right.

To compute this, we use a method where we multiply the numbers out front and add the exponents. For instance, (3 × 10⁵) × (2 × 10º) equals 6 × 10⁵. This notation not only simplifies arithmetic but is also compact and convenient.
