Which fraction converts to a repeating decimal number?
OA. 1/12
OB. 7/8
OC. 14/25
OD. 17/20
OE. 6/10
=======================================================
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.

Find an equation of the line that passes through the point (2, -8) and is perpendicular to the line 2x-6y=10
9514 1404 393
Answer:
3x +y = -2
Step-by-step explanation:
First of all, it is helpful to put the given equation in standard form. We can do that by dividing it by 2 to eliminate the common factor from the numbers.
x -3y = 5
Next, since you want the perpendicular line, you can swap the coefficients of x and y, and negate one of them. This can give you ...
3x +y = (some constant)
The constant will be found using the given point.
3x +y = 3(2) +(-8) = -2 . . . the perpendicular line
An equation is ...
3x +y = -2

Write the point-slope equation of the line that passes through (7,3) whose
slope is 2.
Answer:
y - 3 = 2(x - 7).
Step-by-step explanation:
The point-slope form is
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line.
So the answer is:
y - 3 = 2(x - 7).
Explain why a +b=d.
Answer:a + b + c = 180 ( sum of angles in a triangle )
c + d = 180 ( adjacent angles are supplementary ), thus
a + b + c = c + d ( subtract c from both sides )
a + b = d

3. 125
Step-by-step explanation:
2. You have four squares with a total area of 36. Divide the area by 4 to find the area of 1.
36/4=9
The Area of 1 square is 9. That means that the side of a square is 3.
3. A cube has a side of 5 inches. All the sides of a cube are the same, and the volume formula is l*w*h = V
You can input the number into the equation. 5 * 5 * 5 = V
You can also read this as 5^3.
The Volume = 125

John sells t-shirts. Plain shirts cost $5 and graphic shirts cost $7.
In order to match his product costs, he must make at least $1,200.
Okay so is your question like how many plain and graphic he needs to sell to get more than $1200??
For example if he sells 100 plain shirts(which will come up to $500) and 100 graphic shirts($700) the Total amount earned would be $1200, so we would need to sell at least 100 shirts of each or more to get to $1200.
Also if he sells 240 plain shirts he will get $1200
Or if he sells 172 graphic shirts he will get $1204.
