Express $0.\overline{5}$ as a common fraction in lowest terms.
=======================================================
Explanation:
[tex]0.\overline{5}[/tex] means that the 5's go on forever because of that horizontal bar over top. So we can write it as [tex]0.\overline{5} = 0.55555\ldots[/tex]
The three dots indicate it goes on forever following that pattern.
Let
x = 0.55555....
Multiply both sides by 10 to move the decimal point 1 spot to the right
10x = 5.55555....
Notice how both x and 10x involve a decimal number such that we have a string of 5's going on forever. If we subtract the two equations, then 10x-x becomes 9x, while the (5.55555....) - (0.55555....) simplifies to 5. The decimal portions cancel out when we subtract since they line up perfectly. We're effectively subtracting 5-0 when we cross off the decimal portions.
After those subtractions, we're left with 9x = 5 which solves to x = 5/9 when you divide both sides by 9.
Use of a calculator should show that 5/9 = 0.555555.... to help confirm the answer. Your calculator may show the last digit to be a 6 instead of a 5, but this is due to rounding. Ideally you should have a string of infinitely many 5's, but the calculator can only how so many digits.

The entry tickets at a community fair cost $5 for children and $10 for adults. On a certain day 1000 people entered in the fair and $7,100 is collected. How many adults and how many children were at the fair?
Answer:
C = 580 children.
A = 420 adult.
Step-by-step explanation:
Let the number of children be C.
Let the number of adult be A.
Translating the word problem into an algebraic equation, we have;
A + C = 1000 .......equation 1
10A + 5C = 7100 .......equation 2
A = 1000 - C .......equation 3
Substituting eqn 3 into eqn 2, we have;
10(1000 - C) + 5C = 7100
10000 - 10C + 5C = 7100
10000 - 7100 = 10C - 5C
2900 = 5C
C = 2900/5
C = 580 children.
Now, to find the value of A.
From equation 3;
A = 1000 - C
A = 1000 - 580
A = 420 adult.
Does this table represent a function? Why or why not?
A. Yes, because the y-values are positive numbers
B. No because each x value is different
C. No because none of the y values are the same
D. Yes because every x value corresponds to exactly one y value
Answer:
D) Yes, Because every x-value corresponds to exactly one y-value

What is the equation of the line perpendicular to Y= 1/2x +6 that passes through the point (4,1)
Answer:
Step-by-step explanation:
y= mx+b is the general equation where m is the slope
y= 1/2 x +6 has the slope 1/2
perpendicular lines have the slope negative reciprocal
so the slope of the ⊥ line is -2
y = -x +b , yet for point (4, 1) the x=4 and y =1
1= -4 +b so b= 5
the equation of the ⊥ line is y= -2x+5

Answer:
x=2 and y=−6
sorry this is pretty long, I did not know if you needed the steps or not
Step-by-step explanation:
−2y−10=x;−10x−y=−14
Solve−2y−10=x for x
−2y−10=x
−2y−10+−x=x+−x
−x−2y−10=0
−x−2y−10+2y=0+2y
−x−10=2y
−x−10+10=2y+10
−x=2y+10
-x/-1=2y+10/-1
x=−2y−10
Substitute−2y−10 for x in−10x−y=−14
−10x−y=−14
−10(−2y−10)−y=−14
19y+100=−14
19y+100+−100=−14+−100
19y=−114
19y/19=-114/19
y=-6
Substitute−6 for y in x=−2y−10
x=−2y−10
x=(−2)(−6)−10
x= 2
x=2 and y=−6
-2x + 3 – 5x – 4 = -3x – 8 + 10x
what is x
Answer:
x= 1/2
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x+3−5x−4=−3x−8+10x
Step 1: Simplify both sides of the equation.
−2x+3−5x−4=−3x−8+10x
−2x+3+−5x+−4=−3x+−8+10x
(−2x+−5x)+(3+−4)=(−3x+10x)+(−8)(Combine Like Terms)
−7x+−1=7x+−8
−7x−1=7x−8
Step 2: Subtract 7x from both sides.
−7x−1−7x=7x−8−7x
−14x−1=−8
Step 3: Add 1 to both sides.
−14x−1+1=−8+1
−14x=−7
Step 4: Divide both sides by -14.
Kellie is purchasing the package of dog food shown (dog kibble 7pounds) how many 8 ounce servings can she feed her dog
Answer:
14 servings
Step-by-step explanation:
Step 1
We convert 7 pounds to ounces
0.0625 pound = 1 ounce
7 pounds = x
Cross Multiply
0.0625x = 7
x = 7/0.0625
x = 112 ounces
Step 2
The number of 8 ounce servings she can give to her dog is calculated as:
8 ounces = 1 serving
112 ounces = x servings
Cross Multiply
8 × x = 112 × 1
8x = 112
x = 112/8
x = 14 servings
Therefore, the number of 8 ounce servings she can feed her dog is 14

HELP ME OUT PLEASE!!!
Answer:
So the scale factor would be the length of the new rectangle divided by the length of the corresponding side for the original rectangle. So the scale factor is 1/2. Note: If you're going from a bigger shape to a smaller one, you know that the scale factor must be less than 1.
