Determine if 0.828228222822228222228... is rational or irrational and give a reason for your answer.
Answer:
irrational
Step-by-step explanation:
it cannot be written as a ratio
The given decimal number is a nonterminating and non-repeating decimal it is irrational.
The given decimal number is 0.828228222822228222228...
We need to identify whether the given decimal number is rational or irrational.
What are rational numbers and irrational numbers?Rational Numbers
The term ratio came from the word ratio which means the comparison of any two quantities and is represented in the simpler form of a fraction. A number is considered a rational number if it can be expressed in the form of a/b where both a (numerator) and b(denominator) are integers. The denominator of a rational number is a natural number(a non-zero number). Integers, fractions including mixed fractions, recurring decimals, finite decimals etc all come under the category of rational numbers.
Irrational Numbers
A number is considered an irrational number if it cannot be able to simply further to any fraction of a natural number and an integer. The decimal expansion of irrational numbers is neither finite nor recurring. Irrational numbers include surds and special numbers such as π. The most common form of an irrational number is pi (π). A surd is a non-perfect square or cube which cannot be simplified further to remove the square root or cube root.
Since the given decimal number is a nonterminating and non-repeating decimal it is irrational.

brainliest 1. Tara already knew 4 appetizer recipes before starting culinary school, and she will learn 3 new appetizer recipes during each week of school. Write an equation that shows the relationship between the number of weeks and the number of appetizer recipes. (a) Define your variables. (b) Write a linear equation that can be used to determine the number of appetizer recipes she will learn during school (c) Solve your linear equation to determine the number of recipes that Tara will know after 18 weeks in school (d) Explain your answer to Part 1c.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Number of recipes already known = 4
Number of new recipes learnt per week = 3
Relationship between number of weeks and appetizer recipe :
y = 3w
number of weeks = w
Number of appetizer recipe = y
B.) Linear equation:
y = mx + c
x and y are the independent(x = number of weeks) and dependent variables (y = number of recipes learnt)
C = intercept, value of y, when x = 0 ; number of recipes already known before learning ; 4
m = gradient change in y per change in x; number of recipes Learnt per week ; m = 3
y = 3x + 4
Number of recipes known after 18 weeks :
x = 18
y = 3(18) + 4
y = 54 + 4
y = 58
58 recipes
After 18 weeks, Tara would have learnt (18 * 3) = 54 new recipes plus the already known 4 = (54 + 4) = 58

Hello. :)
So, in order to order numbers, you need to have them all in the same format. For example, in your case, half are fractions and half are decimals. If you want to order them, they all need to be either fractions or decimals.
Let's just convert them to decimals.
In order to do that, all you have to do is divide the numerator by the denominator. Do this to all of the fractions.
-3/10 = -0.3
1/2 = 0.5
Okay, so now all of our terms are in decimal form:
-0.3, 0.5, 0.3, -0.8
So let's start the Ordering process.
Begin with the negative numbers, since they are going to be the smallest.
We have -0.3 and -0.8. If they were positive, 0.8 would be larger. But, in terms of negatives, -0.8 is less than -0.3
So, we have -0.8, -0.3.
Now the positives:
0.5 and 0.3. Just looking at the decimals, you can see that 0.5 is greater than 0.3
So, from least to greatest your answer is:
-0.8, -3/10, 0.3, and 1/2
I hope this helped. :) Feel free to reply with any questions x

Roxanne is going to build a rectangular prism out of 36 one- inch cubes. She wants the height of the rectangular prism to be 3 inches, and she wants the width to be shorter than the length. How many rectangular prisms with different dimensions can she build?
Answer:
3
Step-by-step explanation:
Since Roxanne has 36 one inch cubes, the maximum volume of rectangular prism she can have is 36 in³ = 1 in × 1 in × 36 in.
Now, if Roxanne wants a rectangular prism with height 3 inches, this implies that the area of its base is 36 in³/3 in = 12 in².
We now find all the factors of 12 = 1 × 12, 2 × 6, 3 × 4.
So, we have 3 different areas of base of rectangular prism in which the width is shorter than its length the width being the smaller dimension.
So, the different rectangular prisms in which the volume = 36 in³ in which the width is shorter than its length and has a height of 3 in is
1 × 12 × 3, 2 × 6 × 3, 3 × 4 × 3.
So we have 3 different rectangular prisms

Xpress this number in scientific notation. 0.15880.15880, point, 1588 Hint #11 / 3 Count the zeroes to the right of the decimal point before the leading {1}11: there are 000 zeroes. Hint #22 / 3 If you count the leading digit {1}11, there is {1}11 digit to the right of the decimal point. Hint #33 / 3 So: 0.1588 = {1}.588 \times 10^{{-1}}0.1588=1.588×10 −1
Given:
The number is 0.1588.
To find:
The scientific notation of given number.
Solution:
If a number expressed as a number between 1 and 10 is multiplied by a power of 10, then it is known as scientific notation of the number.
The given number is 0.1588.
Here, leading digit is 1.
There are no zeroes to the right of the decimal point before the leading digit 1.
Leading digit 1 is 1 digit to the right of the decimal value. So,
[tex]0.1588=1.588\times 10^{-1}[/tex]
Therefore, the scientific notation of given number is [tex]1.588\times 10^{-1}[/tex].
3. Andre and Elena are solving this system of equations:
y = 3x
y=9x – 30
- Andre's first step is to write: 3x = 9x - 30
- Elena's first step is to create a new system:
3y=9x
y = 9x - 30
Do you agree with either first step? Explain your reasoning.
Answer:
Andre is correct
Step-by-step explanation:
Andre is correct because the two equations are equal to eachother since they are both equal to y. As for Elena, they seem like they're overcomplicating it. They could do it this way, but it's unnecessary so I think that Andre is more correct because they did it the easier way.
In a classroom with 45 students, there were twice as many girls as boys. How many of each were there?
Answer:
90
Step-by-step explanation:
Dialogue (sometimes spelled dialog in American English) is a written or spoken conversational exchange between two or more people, and a literary and theatrical form that depicts such an exchange.
Answer:
Girls are twice as many as the boys.
So let's assume girls to be 'x' and boys to be 'y' and adopt the simultaneous equation method to find out the answer to X and Y.
Firstly, let's us establish that: x + y = 45
Secondly, for every boy there are two girls. So,
2y = x.
We have the value for the 'x' here in the equation, so we will substitute that in the first equation:
2y + y = 45
3y = 45
y = 15
Boys are 15.
Put this answer into any of the equations now, we will the first one:
x + 15 = 45
x = 30
Girls are 30.
Step-by-step explanation:
Hope this helps
