Answer:
Step-by-step explanation:
[tex]n= 0.142857[/tex]
[tex]1000000n= 0.142857[/tex]
Move the decimal point using the 1000000n
You should get 142857.142857 repeating
Subtract n from both sides [tex]142857.142857- 0.142857[/tex]
You should get 142857 without the repeating decimal.
The equation is now: [tex]142857/999999[/tex] (fraction)
A cool trick to find out if you can reduce that is: [tex]1+4+2+8+5+7[/tex] (equals 27) is the answer to that addition a number divisible by three (yes). So the number 142857 is divisible by 3 which means that you can simplify the fraction.
You can use a calculator for 142857/3 (division) (unless your teacher says you can't)
You should get 47619
You should get[tex]47,619/333333[/tex] (fraction).
I think you can divide that by 3 again. [tex]4+7+6+1+9[/tex] is 27, which is divisible by 3.
Again, you can use a calculator for 47619/3 (division) (unless your teacher says you can't)
You should get 15,873
You should get 15,873/111111 (fraction)
The repeating decimal 0.142857 is equivalent to the fraction 1/7.
Given that we need to convert a repeating decimal 0.142857 as a fraction.
The repeating decimal 0.142857 can be expressed as a fraction. To understand how to convert it, let's denote it as x:
x = 0.142857...
To convert this repeating decimal to a fraction, we can multiply x by a power of 10 to shift the decimal point and eliminate the repeating part.
Since there are six digits in the repeating block (142857), we can multiply x by 10⁶ to remove the repeating part:
10⁶ · x = 142857.142857...
Next, we subtract the original equation from the one above to eliminate the repeating part:
(10⁶ · x) - x = 142857.142857... - 0.142857...
Simplifying the equation:
999999x = 142857
Now, we can solve for x by dividing both sides of the equation by 999999:
x = 142857 / 999999
Simplifying the fraction:
x = 1 / 7
Therefore, the repeating decimal 0.142857 is equivalent to the fraction 1/7.

Cynthia besch  wants to buy a rug for a room that is 21 feet wide and 29 feet long. she wants to leave a uniform strip floor around the rug. she can afford to buy 345 square fee of carpeting. what dimensions should the rug have
Step-by-step explanation:
Let x be the width of the uniform strip floor around the rug.
Then the width of the rug is (21 - 2x) and the length of the rug is (29 - 2x).
(21 - 2x)(29 - 2x) = 345
609 - 100x + 4x^2 = 345
4x^2 - 100x + 264 = 0
x^2 - 25x + 66 = 0
(x - 22)(x - 3) = 0
x = 3 or x = 22 (rejected as x must be less that the width of the room)
Hence the width of the rug is 21 - 2(3) = 15 feet and the length of the rug is 29 - 2(3) = 23 feet.

A survey showed that 4 out of 5 students own a bicycle. Based on this result, how many of the 800 students in a school own a bicycle? Use any strategy to solve.
Answer:
640 students
Step-by-step explanation:
We are told in the question that 4 out of every 5 students owns a bicycle
This also means , out of every 5 students only 1 does not have bicycle
Then we have a ratio of 4 : 1
This means a fraction of 4/5 students own a bicycle in a school
Based on this result, how many of the 800 students in a school own a bicycle?
This calculated as:
4/5 × 800
= 640 students
Therefore, 640 students out of 800 students own a bicycle

Kaya rented a limousine for prom. The company charges a cleaning fee of $100 and an hourly rate of $45. Her total cost for the night was $437.50. For how many hours did Kaya rent the limousine?
Answer:
Number of hours= 7.5
Step-by-step explanation:
Giving the following information:
The company charges a cleaning fee of $100 and an hourly rate of $45.
Her total cost for the night was $437.50
First, we need to structure the total cost formula:
Total cost= 100 + 45*x
x= number of hours
437.5= 100 + 45x
337.5/45= x
x= 7.5
Number of hours= 7.5
Answer:
Kaya rented the limo for about 7.5 hours

A.155.0
B.151.9
C.150.5
D.141.4
E.158.1
Answer:
The answer is option E.Step-by-step explanation:
The length of a line segment or the distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
J(-4,2) and G(146,52)
The the length of the line segment joining the points is
[tex] |JG| = \sqrt{ ({ - 4 - 146})^{2} + ({2 - 52})^{2} } \\ = \sqrt{ ({ -150})^{2} + ({ -50})^{2} } \\ = \sqrt{22500 + 2500} \\ = \sqrt{25000} \\ = 50 \sqrt{10} \\ = 158.11388[/tex]

Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = [tex]x^{4}[/tex] + 7 ( subtract 7 from both sides )
y - 7 = [tex]x^{4}[/tex] ( take the fourth root of both sides )

g(x) = [tex]\sqrt[4]{x-7}[/tex] , x ≥ 7
2.4+10m=6.89 what does m equal
Answer:
m = 0.449
Step-by-step explanation:
Isolate the variable, m. Note the equal sign, what you do to one side, you do to the other. Remember to do the opposite of PEMDAS.
PEMDAS is the order of operation & =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, subtract 2.4 from both sides:
2.4 (-2.4) + 10m = 6.89 (-2.4)
10m = 6.89 - 2.4
10m = 4.49
Divide 10 from both sides:
(10m)/10 = (4.49)/10
m = 4.49/10
m = 0.449
0.449 is your answer for m.

m = 0.449

[tex]2.4+10m=6.89\\\\\mathrm{Subtract\:}2.4\mathrm{\:from\:both\:sides}\\2.4+10m-2.4=6.89-2.4\\\\Simplify\\10m=4.49\\\\\mathrm{Divide\:both\:sides\:by\:}10\\\frac{10m}{10}=\frac{4.49}{10}\\\\Simplify\\m=\frac{4.49}{10}\\\\\left(\mathrm{Decimal}:\quad m=0.449\right)[/tex]

f=(1,0)
Step-by-step explanation:
It super simple, just just move each point to the right 5 lines/units, and up 2 lines/units.
The coordinates of the vertices after a translation 5 units right and 2 units up. C =(1,-8), D =(7,-8), E =(7,0) and F =(1,0)
How to draw a shifted figure if the shifts are provided?Suppose the graph is drawn on the coordinate plane.
Let the shifting be (x,y) → (x+a, y+b)
Then, add 'a' to all x coordinates of the graph's points. Add 'b' to all y coordinates of the graph's points.
The resultant set of new points will be plotted.
Thus it is called origin shift since we think of it as the origin was picked and placed at the point (a,b)(in this case) along with those two axes (x and y axes) and now everything will be measured from this new axes' frame.
Therefore, the coordinates of the vertices after a translation 5 units right and 2 units up.
C =(1,-8)
D =(7,-8)
E =(7,0)
F =(1,0)

What is the solution to the equation One-third (x minus 2) = one-fifth (x + 4) + 2? x = 12 x = 14 x = 16 x = 26
Answer:
x = 26
Step-by-step explanation:
Given
[tex]\frac{1}{3}[/tex] (x - 2) = [tex]\frac{1}{5}[/tex] (x + 4) + 2
Multiply through by 15 to clear the fractions
5(x - 2) =3(x + 4) + 30 ← distribute and simplify both sides
5x - 10 = 3x + 12 + 30, that is
5x - 10 = 3x + 42 ( subtract 3x from both sides )
2x - 10 = 42 ( add 10 to both sides )
2x = 52 ( divide both sides by 2 )
x = 26
