Which number is an irrational number?

A: 0.12

B: 0.1257486

C: 0.12121212

D: 0.111111

Answers

Answer 1
An irrational number is a number that can not be expressed as a rational number(a whole number, repeating decimal number, and a fraction that is rational.)
So 0.1257486 is the answer.
Answer 2

Final answer:

The irrational number in the given options is C: 0.12121212, as it repeats the sequence '12' infinitely without any pattern.

Explanation:

An irrational number is a number that cannot be expressed as a simple fraction (i.e. a ratio of two integers) and has an infinite number of non-repeating decimal places. Out of the given options, the number C: 0.12121212 is an irrational number because it repeats the sequence '12' infinitely without any pattern. The other options, A: 0.12, B: 0.1257486, and D: 0.111111, can all be expressed as fractions and have either a finite decimal representation or a repeating decimal pattern.

Rachel has 60 scones. She sells them to Robbie, Cameron, Louis, Tom and Charlie in that order. Each customer buys more scones then the last and the increase is the same number in each case. Robbie and Cameron's combined total number of scones is three sevenths of the total of Louis, Tom and Charlie. How many scones does each boy buy?

Answers

Robbie bought the smallest amount. Let's use x for that amount.
Let's use n for amount that each following customer increases.

We have:
Robbie=x
Cameron=x+n
Louis=x+n+n
Tom=x+n+n+n
Charlie=x+n+n+n+n

We know that they bought total of 60 scones.
Robbie + Cameron + Louis + Tom + Charlie = 60
x + x+n + x+n+n + x+n+n+n + x+n+n+n+n = 60
5x + 10n = 60 /:5
x + 2n = 12

We are also given this information:
(Robbie + Cameron) = 3/7 * (Louis + Tom + Charlie)
We insert the equations from above:
(x + x+n) = 3/7 * (x+n+n + x+n+n+n + x+n+n+n+n) 
2x + n = 3/7 * (3x + 9n) /*7
14x + 7n = 3* (3x + 9n)
14x +7n = 9x + 27n
We take everything on the left side.
14x + 7n - 9x - 27n = 0
5x - 20n = 0/:5
x - 4n = 0

Now we have two equations:
x + 2n = 12
x - 4n = 0
We solve second one for x and insert it into first one.
x + 2n = 12
x = 4n

4n + 2n =12
6n = 12 /:6
n = 2
x=4*2
x=8


Now we can solve for the amount for each customer.
Robbie=x = 8
Cameron=x+n = 8 + 2 = 10
Louis=x+n+n = 8 + 2 + 2 = 12
Tom=x+n+n+n = 8 + 2 + 2 + 2 = 14
Charlie=x+n+n+n+n = 8 + 2 + 2 + 2 + 2 = 16

Attila the Hun was a ruler of the Hunnic Empire. The Romans feared him greatly until his death since he made quite a habit of invading. The Romans no longer feared him after his death in 453. Let x represent any year. Write an inequality in terms of x and 453 that is true only for values of x that represent years after the year that Attila died.

Answers

The inequality would be x > 453 because any year after he died would be more than the year he died.

Ben has Type 180 word in can type 30 words per minute. Millie has Type 60 words and can type 50 word per minute. How many minutes will it take Millie to catch up with Ben?

Answers

6 minutes.
If x= minutes,
180+30x=60+50x
120=20x
6=x
How many words they have already typed is their starting/ y intercept. Their words per minute is their rate. We need their equations to equal themselves so we can find when they are the same. X will be the amount of minutes and we need X by itself.
180+30x=60+50x
Now let’s subtract 60 from each side.
120+30x=50x
Let’s subtract 30x from each side.
120=20x
Let’s divide each side by 20.
6=x
It will take 6 minutes for Millie to catch up with Ben.

What is the y-intercept of the continuous function in the table?

Answers

Final answer:

The y-intercept of a function is where the graph crosses the y-axis, represented by 'b' in the equation y = mx + b. If a table doesn't show x as zero, one can use the line of best fit by inserting the median x and y values and the slope into the formula b = y - mx to calculate the y-intercept.

Explanation:

The y-intercept of a continuous function can be understood as the point where the function's graph crosses the y-axis. It is typically represented by the variable b in the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept. In the context of the problem provided, if the student is examining a table of values representing a linear relationship, they should look for the value of y when x equals zero to determine the y-intercept directly.

However, if the data does not include an x-value of zero, they could use the line of best fit to calculate the y-intercept by plugging the median x and y values, along with the determined slope, into the formula b = y - mx, where y and x are the medians. For example, if given a slope (m) of 0.09, sum of median x values as 1264, and sum of median y values as 219.5, the y-intercept (b) would be calculated as b = 219.5 - 0.09(1264), which simplifies to approximately 35.25.

This calculation would be necessary if the student is working with data that does not directly provide a scenario where x = 0, such as exam scores or years in a dataset stating from year 1. It's important to note that in some real-world applications, a y-intercept may not be meaningful if the x-value cannot be zero, like in the case of time-based data where the year 0 does not exist.

The y-intercept of the continuous function is (-2). This means that the graph of the function intersects the y-axis at the point (0,-2).

The y-intercept of a continuous function represents the point where the graph of the function intersects the y-axis. In other words, it is the value of y when x is equal to zero.

Looking at the given points:

(0,-6), (-2, 0), (-6, 0), (0,-2), and 0

We can determine the y-intercepts by identifying the points where x is equal to zero.

Let's go through the points one by one:

1. (0,-6): This point does not have a y-intercept because the x-coordinate is not zero.

2. (-2, 0): This point also does not have a y-intercept because the x-coordinate is not zero.

3. (-6, 0): Again, this point does not have a y-intercept because the x-coordinate is not zero.

4. (0,-2): Finally, this point does have a y-intercept because the x-coordinate is zero. Therefore, the y-intercept is -2.

5. 0: This is not a point, but simply the value of zero. It does not have a y-intercept because it does not represent a point on the graph.

To summarize, the y-intercept of the continuous function is (-2). This means that the graph of the function intersects the y-axis at the point (0,-2).

PLEASE HELP = simplify 3/4(-10+2/5)

Answers

There are many ways to do this depending on the property you have to use:

If you use the distributive property, you need to distribute 3/4 to -10 and 2/5. Distribute means you will multiply it so your resulting equation will be this:

[tex] \frac{-30}{4} - \frac{6}{20} [/tex]

Before you can add, you need to first make them like terms because you cannot add unlike fractions. Get the LCD and form your new equation:

[tex] \frac{-150+6}{20} [/tex]

Now you can just add them together to get:
[tex] \frac{-144}{20} [/tex]

and then simplify your fraction:
[tex] \frac{-36}{5} [/tex] or - [tex] \frac{36}{5} [/tex] 

The whole fraction becomes negative because when you divide integers and of them is negative, the final answer will be negative.

Answers

Jenny is 3 less than half of a, or 1/2a - 3.  Fraz is twice a + 7, or 2a+7.
Final answer:

Jenny's age in terms of Anne's age is j = (1/2)a - 3 and Fraz's age in terms of Anne's age is f = 2(a + 7).

Explanation:

To express Jenny's age in terms of Anne's age (a), we can use the information given that Jenny is 3 years less than 1/2 of Anne's age. Therefore, Jenny's age (j) can be expressed as:

j = (1/2)a - 3

To express Fraz's age in terms of Anne's age (a), we can use the information given that Fraz is twice the sum of Anne's age and 7. Therefore, Fraz's age (f) can be expressed as:

f = 2(a + 7)
