Explanation:
Using a calculator shows that
1/12 = 0.0833333.... where the 3's go on forever7/8 = 0.87514/25 = 0.5617/20 = 0.856/10 = 0.6We see that nearly all of the decimal values are terminating decimals. This means the decimals don't go on forever, so the decimals stop at some point.
Only 0.083333... goes on forever, so that's why 1/12 converts to a repeating decimal number.
----------------------
A way you can determine this without a calculator is to use long division. Or you could use the idea that if the denominator has prime factors other than 2 and 5, then the decimal will repeat forever.
Note how the denominators of the fractions for choices B through E all have prime factors of either 2s only, 5s only, or a mix of 2s and 5s. This fact is why we have terminating decimals here.
In contrast, 12 has prime factorization 2*2*3. That 3 as a prime factor is why the decimal repeats forever.
The only fraction that converts to a repeating decimal number is 1/12.
What is decimal?Decimal is a fraction whose denominator is a power of ten and whose numerator is expressed by figures placed to the right of a decimal point.
Given is to find a fraction that converts to a repeating decimal number.
Repeating decimals are the decimals of the form -
2.7777...
2.34343434...
2.43434343....
Now, we have the fractions and their corresponding decimal numbers as follows -
1/12 = 0.0833333333333333 : Yes7/8 = 0.875 : No14/25 = 0.56 : No17/20 = 0.85 : No6/10 = 0.6 : NoTherefore, the only fraction that converts to a repeating decimal number is 1/12.

-5x – 2 = -13
Answer:
2.20

I need help I don’t understand
Answer:
x=50
Step-by-step explanation:
A= 30+2x
B= x
Supplementary angles are angles that always add up to 180 degrees.
therefore, A + B=180 degrees
30 + 2x + x = 180: Now we solve
30 + 3x =180
subtract 30 from both sides
3x=150
divide by 3
3x/3 = 150/3
x= 50

Step-by-step explanation:
The length of each square on the grid represents 1 cm. The scale
from an actual rectangle to the drawing is 24 in. to 1 cm. Make a
new scale drawing where each centimeter represents 16 in.
Label the length and width of your drawing in centimeters.
Answer:
40.64 cm x 40.64 cm
Step-by-step explanation:
The directions say that 1 centimeter = 16 inches.
1 inch = 2.54 centimeters
Multiply by 16.
16 inches = 40.64 centimeters
We know each length of the square is 1 cm or 16 inches, according to the above.
(btw problem says rectangle, a square can be a rectangle.)
4x^2-21x-18=0
Find the discriminate
a = 4, b = -21, c = -18
to keep from getting "mixed up", evaluate the discriminant first ...
b<sup>2</sup> - 4ac = (-21)<sup>2</sup> - 4(4)(-18) = 729
sqrt(729) = 27
x = (21 +/- 27)/8
x = -3/4, x = 6
since the discriminant is a perfect square, the original quadratic will factor ...
4x<sup>2</sup> - 21x - 18 = 0
(4x + 3)(x - 6) = 0
x = -3/4, x = 6
Answer:729
Step-by-step explanation: Use the values of a, b and c to find the discriminant. Which is 729

What is the maximum value of 3x + 5y in the feasible region?
(3, 7)
(0,7)
(6, 3)
(6, 0)
Answer:
Minimum value is 18
It occurs at P(6,0)
Step-by-step explanation:
The given objective function is
The vertices of the feasible region are .
We plug in the vertices in to feasible region and evaluate to obtain,
P(0,7) = 3(0) + 5(7)
P(0,7) = 0+35
P(0,7) = 35
P(3,7) = 3(3) + 5(7)
P(3,7) = 9+35
P(3,7) = 44
P(6,3) = 3(6) + 5(3)
P(6,3) = 15+15
P(6,3) = 33
P(6,0) = 3(6) + 5(0)
P(6,0) = 18+0
P(6,0) = 18

Half of a number x is equal to 9 less than 2 times that same number. What is the
number
Answer:
[tex]x = 6[/tex]
Step-by-step explanation:
Analyzing the statement one after the other:
Half a number x: [tex]\frac{1}{2}x[/tex]
Equals to: [tex]=[/tex]
9 less than twice that same number: [tex]2x - 9[/tex]
Bring them together, we have:
[tex]\frac{1}{2}x = 2x-9[/tex]
Collect Like Terms
[tex]\frac{1}{2}x - 2x= -9[/tex]
[tex]\frac{x}{2} - 2x= -9[/tex]
[tex]\frac{x - 4x}{2} = -9[/tex]
[tex]\frac{ - 3x}{2} = -9[/tex]
Multiply through by 2
[tex]2 * \frac{ - 3x}{2} = -9 * 2[/tex]
[tex]- 3x = -18[/tex]
Divide through by -3
[tex]x = 6[/tex]

Add:
0=6???
Impossible
So no solution.
Hope this helps plz mark brainliest :D
Answer:
No solution
Step-by-step explanation:
First we need to solve the equations.
I'll use the combining method
To do the combining method you need to get one of the variables in the first equation to be the negative correspondent to the same variable in the second equation.
(Ex:
If there was 2x in the first equation we would want there to be -2x in the second so they cancel out.)
y=6x+2
subtract 6x from each side to get the variables to line up
y-6x=2
3y-18x=12
To get -6x to equal 18x, we will multiply everything in the first equation by -3
-3y+18x=-6
3y-18x=12
Now combine the two terms
-3y and 3y cancel out
18x and -18x cancel out
-6+12=6
We are left with 0=6.
0 does not equal 6 so there is no solution.
