Final answer:

To write a rational number as a repeating decimal, perform long division. -7/9 as a repeating decimal is -0.7777..., 11/15 is 0.7333..., and 8/3 is 2.6666...

Explanation:

To write a rational number as a repeating decimal, you need to perform a long division. Let's go through each of the given rational numbers:

1. -7/9

When you divide -7 by 9, you get -0.7777… with the 7s repeating. So, -7/9 as a repeating decimal is -0.7777…

2. 11/15

When you divide 11 by 15, you get 0.7333… with the 3s repeating. So, 11/15 as a repeating decimal is 0.7333…

3. 8/3

When you divide 8 by 3, you get 2.6666… with the 6s repeating. So, 8/3 as a repeating decimal is 2.6666…

The number of hours will they be 280 miles apart will be 2 hours.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

Two vehicles leave new york simultaneously going in inverse headings. one goes at a typical speed of 77 mph and the other at 63 mph.

The relative speed is given as,

S = 77 + 63

S = 140 miles per hour

The number of hours will they be 280 miles apart will be calculated as,

Time = 280 / 140

Time = 2 hours

The number of hours will they be 280 miles apart will be 2 hours.

To calculate the map distance between Austin and Dallas with a scale of 1 inch representing 20 miles, and an actual distance of 195 miles, set up a proportion and solve to find that Austin and Dallas would be 9.75 inches apart on the map.

To find out how many inches Austin is from Dallas on the map, we need to set up a proportion. The scale given on the map is 1 inch represents 20 miles. We know the actual distance between Austin and Dallas is 195 miles. To calculate the distance on the map, we use the proportion 1 inch / 20 miles = x inches / 195 miles.

Cross-multiply to solve for x:

(1 inch) * (195 miles) = (20 miles) * (x inches)

195 inch-miles = 20x inch-miles

Now, divide both sides by 20 miles to solve for x:

x = 195 inch-miles / 20 miles

x = 9.75 inches

So, on the map, Austin and Dallas would be 9.75 inches apart.

The figure that shows how a shape can be rotated about an axis to form a disc is (c) rectangle

The shapes in the figures are given as:

A. Rectangle

B. Semicircle

C. Inscribed semicircle

D. Another Rectangle

When the first rectangle is rotated about the axis, it forms a spiral shape

Rotating a semi-circle and the inscribed semi-circle about its axis would form a hemisphere

However, when a rectangle that has one of it sides on the axis is rotated, it forms a cylinder or disc

Hence, the figure is (d) rectangle

The regular polygon with an interior angle of 140 degrees has 9 sides. This conclusion can be reached by using the formula for the interior angle of a polygon, which is (n-2)*180/n, where 'n' represents the number of sides.

The number of sides in a regular polygon can be determined using the formula for the interior angle of a polygon, which is (n-2)*180/n, where 'n' represents the number of sides. This formula comes from the fact that a polygon can be divided into (n-2) triangles, each of which has angles summing up to 180 degrees.

In this particular case, an interior angle of 140 degrees is given. So we will set up an equation: 140 = (n-2)*180/n. Solving for 'n', we get a value of 9.

Therefore, the regular polygon with an interior angle of 140 degrees has 9 sides.

The solution for given equation 17=-13-8x is x = -15/4.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

The given equation is,

17 = -13 - 8x

Now to solve the equation following steps are followed :

adding 13 both the sides of the equation,

17 + 13 = -13 - 8x + 13

or, 17 + 13 = -13  + 13 - 8x

Solving them we get,

30 = - 8x

or, - 8x = 30

multiplying -1 both side

- 8x*(-1) = 30*(-1)

Solving them we get,

8x = -30

dividing both side by 2

8x/2 = -30/2

Solving them we get,

4x = -15

dividing both side by 4

4x/4 = -15/4

Solving them we get

x = -15/4

Hence,the solution for given equation 17=-13-8x is x = -15/4.

Answer:

y=3

Step-by-step explanation:

The required line will be y = 3 which is passing through points (6,3) and (-4,3)

The slope of the line is defined as the gradient of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Assume two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

To determine the line of passing through points (6,3) and (-4,3)

We have been given two points :(6,3) and (-4,3)

Let the required line will be:

(y - y₁) =  [(y₂ - y₁)/(x₂ -x₁ )](x -x₁  )

Here

x₁ = 6, y₁ = 3

x₂ = -4, y₂ = 3

(y - y₁) =  [(y₂ - y₁)/(x₂ -x₁ )](x -x₁  )

Substitute values in the above formula

(y - 3) =  [(3 - 3)/(-4 -6 )](x -6 )

(y - 3) =  [(0)/(-10 )](x -6 )

(y - 3) = 0

y = 3

Therefore, the required line will be y = 3

Answer: supplementary, complementary, neither.

Step-by-step explanation:

The distance formula is simply a variation of the theorem. The method is the same with the Pythagorean however we are now dealing with 2 sets of points instead of 2 lengths. 

In the distance formula, the lengths are derived from the (x1,y1)->(x2,y2) coordinate points and the formula simplified. We still square the difference of x’s and difference of y’s to get our two squares then square root the sum to give our length. While the Pythagorean theorem is directly the sum of the square of the other two sides. 

Nevertheless, both formulas work on the same principle.

Answer:

Both formulas can be used to find the distance between two points on the coordinate plane. The vertical leg of the right triangle represents the difference in the y values of the two points. The horizontal leg of the right triangle represents the difference in the x values of the two points. The hypotenuse of the right triangle represents the distance between the two points.
