A repeating decimal is a recurring decimal. It has no end when divided.

9/3 is 3 so it is a terminating decimal.

Answer:

The single repeating digit is 3.

Step-by-step explanation:

Answer:

y = -7,   y = -3

Step-by-step explanation:

(y - 3)² = 2y² + 4y + 30

expand:

y² - 6y + 9 = 2y² + 4y + 30

subtract 30 from both sides

y² - 6y + 9 - 30= 2y² + 4y + 30 - 30

simplify:

y² - 6y - 21 = 2y² + 4y

subtract 4y from both sides

y² - 6y - 21 -4y = 2y² + 4y - 4y

simplify:

y² - 10y - 21 = 2y²

subtract 2y² from both sides

y² - 10y - 21 - 2y² = 2y² - 2y²

simplify:

-y² - 10y - 21 = 0

solve y by quadratic equation

         - (-10) ± √ (-10² - 4(-1)(21)

y = --------------------------------------

               2(-1)

y = -7,   y = -3

Expanding brackets.

[tex]y^2-6y+9=2y^2 +4y+30[/tex]

Subtracting (y² - 6y + 9) from both sides, then switching sides.

Answer: -3/2

Step-by-step explanation:

There are two methods to find the slope

METHOD 1. Rise/Run

Rise: the y-axis value

Run: the x-axis value

In the graph, rise/run=3/2

The line is going down, so it should be negative

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf 240 \: {inches}^{2} }}}}[/tex]

Step-by-step explanation:

Given,

Length of a rectangle = 20 inches

Perimeter of a rectangle = 64 inches

Area of a rectangle = ?

Let width of a rectangle be ' w ' .

First, finding the width of a rectangle

[tex] \boxed{ \sf{perimeter = 2(l + w)}}[/tex]

plug the values

⇒[tex] \sf{64 = 2(20 + w)}[/tex]

Distribute 2 through the parentheses

⇒[tex] \sf{64 = 40 + 2w}[/tex]

Swap the sides of the equation

⇒[tex] \sf{40 + 2w = 64}[/tex]

Move 2w to right hand side and change it's sign

⇒[tex] \sf{2w = 64 - 40}[/tex]

Subtract 40 from 64

⇒[tex] \sf{2w = 24}[/tex]

Divide both sides of the equation by 2

⇒[tex] \sf{ \frac{2w}{2} = \frac{24}{2} }[/tex]

Calculate

⇒[tex] \sf{w = 12 \: inches}[/tex]

Width of a rectangle ( w ) = 12 inches

Now, finding the area of a rectangle having length of 20 inches and width of 12 inches

[tex] \boxed{ \sf{area \: of \: rectangle = length \: \times \: \: width}}[/tex]

plug the values

⇒[tex] \sf{area \: of \: rectangle =20 \times 12 }[/tex]

Multiply the numbers : 20 and 12

⇒[tex] \sf{area \: of \: rectangle = 240 \: {inches}^{2} }[/tex]

Hence, Area of a rectangle = 240 inches²

The triangle is a right triangle.

We can use trig functions to solve for the problem.

[tex]\sf \displaystyle cos (\theta) = \frac{adjacent}{hypotenuse }[/tex]

[tex]\sf \displaystyle cos (34) = \frac{x}{4.8 }[/tex]

Multiplying both sides by 4.8.

Answer:

(0, -5)

Step-by-step explanation:

When we rotate a point around the origin 180°, the original coordinates (x, y) become (-x, -y).

So,

-0 is just 0 (since 0 is both negative and positive)

-(5) is -5

This makes our new point (0, -5).

Answer:

3,000. You take 15,000 and multiply by .4 to get how much she spent on rent (6,000). They you subtract the rent money from her total pay to get her money that she spent on living expenses, clothes and entertainment in total (9,000). Since she spent her money in six parts (3+2+1), you divide 9,000 by 6 to get 1,500 to get each part. Since for entertainment she has two parts you multiply 1,500 by 2 to get 3,000.

Answer:

(a) 14.21 = 0.80x +  0.11 (0.80x)

(b) The original price of the t-shirt was $16.

Step-by-step explanation:

The information provided are:

(a)

Assume that the original price of the t-shirt was $x.

The discounted amount would be, x ( 1 - 0.20) = 0.80x.

The sales tax amount would be, 0.11 (0.80x).

Then the total amount paid by Marvin can be represented by the equation:

Total = Discounted amount + Sales tax amount

14.21 = 0.80x +  0.11 (0.80x)

Thus, the equation that can be used to find the original price of the t-shirt is:

14.21 = 0.80x +  0.11 (0.80x)

(b)

Compute the value of x as follows:

[tex]14.21 = 0.80x + 0.11 (0.80x)[/tex]

[tex]14.21=0.80\times 1.11\times x[/tex]

     [tex]x=\frac{14.21}{0.80\times 1.11}\\\\x=16.0023\\\\x\approx \$16[/tex]

Thus, the original price of the t-shirt was $16.

Answer:

Rectangle

Step-by-step explanation:

Opposite sides (1, 1), (4,1) and (1, 3), (4,3) are horizontal and have length 3.

Opposite sides (1, 1), (1, 3) and (4, 1), (4,3) are vertical and have length 2.

There two pairs of opposite sides that are congruent, so this is a parallelogram. Since not all sides are congruent, this is not a square or a rhombus.

In addition, vertical sides and horizontal sides form right angles, so this is a parallelogram with right angles. It is a rectangle.

Answer:

It will take approximately 9.3 weeks for Kevin to lose the

Step-by-step explanation:

current weight  of Dog = 78 pounds

Required weight to be shed off = 14 pounds

weight lost in 1 week = 1.5 pounds

Let the number of weeks required to lose 14 pounds be w.

Assuming that the rate of weight loss per week is constant

(weight lost in 1 week) × (number of weeks) = 14 pounds

1.5 × w = 14

w = 14 ÷ 1.5 = 9.3 weeks

Therefore it will take approximately 9.3 weeks for Kevin to lose the weight
