Answer:
360
Step-by-step explanation:
Write and solve an equation:
(1/6)(1/3)(1/4)n = 5
Multiplying the left side by (6)(3)(4), or 72, an
Multiply both sides by 6. The resulting equation will still be true, but not have 6 in the denominator:
(1)(1/3)(1/4)n = 5(6) = 30
Mult both sides by 12. The resulting equation will still be true, but not have (3)(4) in the denominator:
(1)(1)(1)n = 360
Then n = 360.
Check: Does (1/6)(1/3)(1/4)(360) = 5?
Yes. This confirms that the unknown number n is 360.
Let us find the number step by step.
Let the unknown number be represented by 'x'.
We are given that one-sixth of one-third of one-fourth of this number is equal to five.
Let's break this down:
One-fourth of x is represented by x/4.
Now, we take one-third of that amount, which means we multiply (x/4) by 1/3, giving us (x/4) * (1/3).
Finally, we take one-sixth of the result from the previous step, so we then multiply by 1/6, yielding (x/4) * (1/3) * (1/6).
The expression we have is:
(x/4) * (1/3) * (1/6) = 5
To solve for x, we must clear the fractions by performing the multiplications:
(x/4) * (1/3) * (1/6) can be simplified before we do anything else:
* 1 * 1 = x
--
4 * 3 * 6 72
So we have:
x/72 = 5
To solve for x, multiply both sides of the equation by 72:
x = 5 * 72
Now, let's do the multiplication:
x = 360
Therefore, one-sixth of one-third of one-fourth of 360 is equal to five.

what are two fractions equivalent to 5/12
Answer:
10/24 and 15/36, more answers possible
Step-by-step explanation:
if you multiply both the numerator and denominator by the same number, it will always be equivalent to 5/12, as you can simplify it back to that fraction.
5/12, multiply both by two, and you have 10/24
5/12, multiply both by three, and you have 15/36
10/24 and 15/36 are fractions equivalent to the given fraction.
10/24: This is equivalent to 5/12 because it can be reduced to 5/12 by dividing both the numerator and the denominator by 2.
15/36: This is another fraction equivalent to 5/12 since it can be reduced to 5/12 by dividing both the numerator and denominator by 3.

What is a function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
Now let the function be,
f(x) = ax² + bx + c
To find,
f(x) + f(x) + f(x)
we have,
f(x) + f(x) + f(x) = (ax² + bx + c) + (ax² + bx + c) + (ax² + bx + c)
⇒ f(x) + f(x) + f(x) = 3(ax² + bx + c)
or, f(x) + f(x) + f(x) = 3ax² + 3bx + 3c
Similarly,
3f(x) = 3(ax² + bx + c)
or, 3f(x) = 3ax² + 3bx + 3c
now to find f(2), put x = 2 in f(x). we get,
f(2) = a2² + b2 + c
or, f(2) = 4a + 2b + c
Therefore,
3f(2) = 3(4a + 2b + c)
or, 3f(2) = 12a + 6b + 3c
hence, the required answer is,
f(x) + f(x) + f(x) = 3ax² + 3bx + 3c
3f(x) = 3ax² + 3bx + 3c
3f(2) = 12a + 6b + 3c

x = (8.75 - 2 5/6) / 7.1 + (4 1/2 + 2 2/3) / 4 3/10
x = 2.5
Answer:
2 1/2
Step-by-step explanation:
Order of operations rules require that we do any work within parentheses first. Thus, calculate (8.75 - 2 5/6); it is (5 11/12). Next, calculate (4 1/2 + 2 2/3); it is ( 7 1/6). So what we have now looks like:
(5 11/12) / 7.1 + (7 1/6) / (43/10) (Note that 4 3/10 = 43/10)
Performing the two indicated divisions, we get:
5/6 + 1 2/3.

What is the triangle?
In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices.
A triangle with sides of lengths 20, 21, and 29 is a right triangle.
Three numbers can be the sides of a triangle if the sum of two of them is greater than the third. So, since
20+21 > 29,
20+29 > 21, and
21+29 > 20

What is the y-intercept of this function?
Answer:
4
Step-by-step explanation:
a linear function is
y = ax + b
so, for the first pair of x, y
8.5 = 2a + b
b = 8.5 - 2a
the second pair
15.25 = 5a + b
let's use the substitution information from the first pair :
15.25 = 5a + 8.5 - 2a
6.75 = 3a
a = 2.25
b = 8.5 - 2×2.25 = 8.5 - 4.5 = 4
so, we get as linear function
y = 2.25x + 4
that means the y-intercept (x = 0) is at y = 4
y = 2.25×0 + 4 = 4
The y-intercept of this function will be at (0, 4).
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Then the linear equation will be
y - 8.50 = [(31.00 - 8.50) / (12 - 2)] (x - 2)
y - 8.50 = 2.25(x - 2)
y - 8.50 = 2.25x - 4.5
y = 2.25 + 4

The answer is:
The correct options are:
A) [tex]y-2=-0.75(x-3)[/tex]
and
D) [tex]y-5=-0.75(x+1)[/tex]
Why?To find the correct answers, we need to find a equation that meet the following charactheristics:
From the graph we can se that the function:
- Has a negative slope (is decreasing)
- Pass throught the points: (-1,5) and (3,2)
Now, discarding from the given options, we have:
A.[tex]y-2=-0.75(x-3)[/tex]
We have that the coefficient of the linear term is negative (-0.75), so, the slope is negative (the function is decreasing).
Evaluating the points, we have:
Evaluating (-1,5)
[tex]5-2=-0.75(-1-3)[/tex]
[tex]3=-0.75(-4)[/tex]
[tex]3=3[/tex]
Evaluating (3,2):
[tex]2-2=-0.75(3-3)[/tex]
[tex]0=-0.75(0)[/tex]
[tex]0=0[/tex]
We have that the equation is satisfied, so, the line pass through the given points.
Hence, we have that the equation A is an equation of the line shown.
B.[tex]y-5=-0.75(x-1)[/tex]
We have that the coefficient of the linear term is negative (-0.75), so, the slope is negative (the function is decreasing).
Evaluating the points, we have:
Evaluating (-1,5)
[tex]5-5=-0.75(-1-1)[/tex]
[tex]0=-3.5[/tex]
Hence, we have that since the equation is not satisfied, the line shown is not passing through the point (-1,5) meaning that the equation is not an equation of the line shown.
So, we have that the equation B is not equation of the line shown.
C.[tex]y-3=-0.75(x-2)[/tex]
We have that the coefficient of the linear term is negative (-0.75), so, the slope is negative (the function is decreasing).
Evaluating the points, we have:

[tex]2=2.25[/tex]
Hence, we have that since the equation is not satisfied, the line shown is not passing through the point (-1,5) meaning that the equation is not an equation of the line shown.
So, we have that the equation B is not equation of the line shown.
D.(assuming you committed a mistake writing the options and the equality sign is missing)
[tex]y-5=-0.75(x+1)[/tex]
We have that the coefficient of the linear term is negative (-0.75), so, the slope is negative (the function is decreasing).
Evaluating the points, we have:
Evaluating (-1,5)
[tex]5-5=-0.75(-1+1)[/tex]
[tex]0=-0.75(0)[/tex]
[tex]0=0[/tex]
Evaluating (3,2)
[tex]2-5=-0.75(3+1)[/tex]
[tex]-3=-0.75(4)[/tex]
[tex]-3=-3[/tex]
We have that the equation is satisfied, so, the line pass through the given points.
Hence, we have that the equation B is an equation of the line shown.
Finally, we have that the correct options are:
A) [tex]y-2=-0.75(x-3)[/tex]
and
D) [tex]y-5=-0.75(x+1)[/tex]
Have a nice day!
PLEASE ANSWER RIGHT AWAY!!!!
The answer is:
The first option,
[tex]y=-\frac{1}{2}x-3;x<-2[/tex]
Why?To answer the question, we need to look for an inequality that fits with the following description:
- Negative slope, since the segment "a" is decreasing.
- x- axis interception at x equal to -6
- One of its point is located at (-2,-2)
- The segment exists from -∞ to -2.
So, checking we have:
Firs option
[tex]y=-\frac{1}{2}x-3[/tex]
With,
[tex]x<-2[/tex]
- Finding the y-axis component when x is equal to -2, we have:
[tex]y=-\frac{1}{2}*(-2)-3\\y=1-3=-2[/tex]
We have that one of the points of the segments is located at (-2,-2)
- Finding the "x" intercept, we have:
[tex]0=-\frac{1}{2}x-3\\\\\frac{1}{2}x=-3\\\\x=2*-3=-6[/tex]
Also, (from the inequality and the graph) we know that, the given segment exists from the negative infinite numbers to -2.
Hence, we can know that the first option meets all the requirements:
[tex]Slope=-\frac{1}{2}[/tex]
[tex]x-axis_{interception}=-6[/tex]
[tex]Point(-2,-2)[/tex]
and from the inequality, we know that the segment exists from -∞ to -2.
Have a nice day!
The table shows a darts club's income in 2017 from a raffle, a quiz and membership fees. Raffle =£350 Quiz=Entry fees =14 at £4 each Refreshments=£44 Membership fees=20 at £20 each. Express as a ratio the income from the raffle to the income from the quiz to the income from membership fees. Give your ratio in its simplest form
Answer:
7:2:8.
Step-by-step explanation:
The income form the raffle = £350
Income from the quiz = 14*4 = £56 + £44 = £100
Income from membership fees = 20*20 = £400.
The ratio of raffle : quiz : fees
= 350:100:400
Dividing each number by 50:
= 7:2:8 in simplest form.
Answer:
A ratio the income from the raffle to the income from the quiz to the income from membership fees is 7:2:8.
Step-by-step explanation:
Given : The table shows a darts club's income in 2017 from a raffle, a quiz and membership fees.
To find : Express as a ratio the income from the raffle to the income from the quiz to the income from membership fees ?
Solution :
The raffle amount is £350.
Quiz, entry fees is 14 at £4 each and refreshment is £44.
The quiz amount is £[tex]14\times 4[/tex]+£44=£56+£44=£100
Membership fees=20 at £20 each.
The membership amount is £[tex]20\times 20[/tex]=£400
Now, the ratio of income from the raffle to the income from the quiz to the income from membership fees is
The ratio of raffle : quiz : membership
[tex]R= 350:100:400\\\\R= 35:10:40\\\\R=7:2:8[/tex]
Therefore, a ratio the income from the raffle to the income from the quiz to the income from membership fees is 7:2:8.
Taxes are used for which of the following?
Depending on the country, most democracies use taxes for:
-public programs (any governmentally run or funded services)
-infrastructure (roads, bridges, etc)
-the military
-schools
-governmental departments (EPA, Department of Homeland Security, etc)
-government employee paychecks
And SOMETIMES:
-universal healthcare
-college/university
-etc.
Taxes are used to fund government services, reduce income inequalities, and support state and local government activities.
Explanation:Taxes are used for a variety of purposes. They are primarily used to fund government services such as military, police, education, infrastructure, and social security. Taxes are also used to reduce income and wealth inequalities by transferring income to lower income groups. Additionally, taxes are used to support state and local government activities and services.
For example, in the United States, the federal government raises revenue through income taxes, corporate earnings taxes, and sales taxes on goods such as gasoline, alcohol, and tobacco. State and local governments also collect taxes, including income, property, and sales taxes, which fund activities like maintaining public parks and providing a police force.
Overall, taxes play a crucial role in financing government operations and essential public services that benefit communities.
The values for three different sets of data are shown below.
Without calculating any statistics, Jadyn knows that data set 1 would have the least mean absolute deviation among the
three sets. Which statement explains how she knows?
Answer:
I'd say C Sets 2 and 3 contain outliers.
Step-by-step explanation:
Set 2 has an outlier of 90, while set 3 has an outlier of 40. 40 isn't as much of an outlier as 90 is, so I'm not absolutely sure. Cmakes the most sense though.
Answer: Third option.
Step-by-step explanation:
The standard deviation increases as we have more values that are far away from the mean.
For example, in data set 2, we can see that most of hour points are between 38 and 49, but we also have a point with a value of 90, so we may expect that this data set has a big standard deviation.
The data set 3 is similar, most of our points are between 24 and 31, and we have a value that is on 40, so again we have an outlier that increases the value of the standard deviation.
Noticing it we can conclude that data set 2 and data set 3 have a greater standard deviation than set 1.
The correct option is the third option.
