Which of the following tables does NOT represent a function?

Answer:

1) For 3 tickets, the cost is $12

2) For 5 tickets, the cost is $20

3) $28 can purchase 7 tickets

4) For 10 tickets, the cost is $40

Step-by-step explanation:

1) For 3 tickets

8 = 2

x = 3

(8 ÷ x) = (2 ÷ 3)

Cross multiply,

2x = 8 x 3

2x = 24

x = 24 ÷ 2

x = $12

Use the same principle for the other questions. Use X (or any other variable) to represent the missing value, I e. the value you are calculating.

I hope this helps.

Answer:

The lines moves lower.

Step-by-step explanation:

The steepness of a line is related to the slope, m.

b is the y-intercept, not the slope.

b is where the line intersects the y-axis.

Changing b changes the vertical position of the line.

Answer: The lines moves lower.

Answer:

42

Step-by-step explanation:

For the square 6 x 5 = 30

For the triangle 6 x 4 x 1/2 = 12

or 6 x 4 ÷ 2 = 12

add them both 12 + 30 = 42

Let's take this step-by-step:

         The mathematical name of this shape is a right trapezoid

              ⇒ It is a trapezoid since the image shows a quadrilateral that

                  has two parallel sides and two non-parallel sides. It is a right

                  trapezoid because it has two rights angles

          The cube has 6 faces

               ⇒ faces are the individual flat surfaces of an object

                   ⇒by looking at a picture of a cube, we see it has 6 sides

                       ⇒ (I attached an image of a cube below)

Hope that helps!

Answer:

x = 35

Step-by-step explanation:

The figure has 6 angles so the figure is a convex hexagon

The sum of interior angles in a convex hexagon is equal to 720

4x - 5 + 117 + 3x - 3 + 3x + 6 + 118 + 4x -3 = 720 add like terms

14x + 230 = 720 subtract 230 from both sides

14x = 490 divide both sides by 14

x = 35

Answer:

x = 6

Step-by-step explanation:

Solve for x:

-(7 x)/3 + 14 = 0

Put each term in -(7 x)/3 + 14 over the common denominator 3: -(7 x)/3 + 14 = -(7 x)/3 + 42/3:

(-(7 x)/3 + 42/3) = 0

-(7 x)/3 + 42/3 = (-7 x + 42)/3:

((-7 x + 42)/3) = 0

Multiply both sides of (-7 x + 42)/3 = 0 by 3:

(3 (-7 x + 42))/3 = 3×0

(3 (-7 x + 42))/3 = 3/3×(-7 x + 42) = -7 x + 42:

(-7 x + 42) = 3×0

0×3 = 0:

-7 x + 42 = 0

Subtract 42 from both sides:

(42 - 42) - 7 x = -42

42 - 42 = 0:

-7 x = -42

Divide both sides of -7 x = -42 by -7:

(-7 x)/(-7) = (-42)/(-7)

(-7)/(-7) = 1:

x = (-42)/(-7)

The gcd of 42 and -7 is 7, so (-42)/(-7) = (-(7×6))/(7 (-1)) = 7/7×(-6)/(-1) = (-6)/(-1):

x = (-6)/(-1)

(-6)/(-1) = (-1)/(-1)×6 = 6:

The area of the quarter circle is equal to one-fourth area of the circle. Then the area of the quarter circle is 86.59 square inches.

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

A corner shelf is 1/4 of a circle and has a radius of 10.5 inches.

Then the area of the quarter circle will be

[tex]\rm Area = \dfrac{\pi r^2}{4}\\\\\rm Area = \dfrac{\pi \times 10.5^2}{4}\\\\\rm Area = \dfrac{\pi \times 110.25}{4}\\\\\rm Area = \dfrac{346.36}{4}\\\\\rm Area = 86.59 \ \ in^2[/tex]

The number of ways is an illustration of selections and arrangements.There are 16 ways to order a two-course meal.

An arrangement is defined as a combination of things that make up a design or that are laid out in a certain way

The given parameters are

Appetizer=8

Main=6

A person can choose 1 a-piece from each menu.

This means that:

There are 8 ways of selecting appetizers, and 2 ways of selecting the main courses.

So, the number of ways (n) is:

[tex]\rm n=Appetizer\times Main[/tex]

Answer:

2396

Step-by-step explanation:

Let the diameter = d

Let the height = h

Formula

Metric Tons = k * d^4 / h^2

Solution

Metric Tons = 64

d = 2

h = 9

k = ?

(You can't do the second part by not using a ratio unless you  put k in and solve for it)

64 = 2^4 k / 9^2

64 = 8 *k / 81

64 * 81 / 8 = k

5184 / 8 = k

k = 648

Solve for the second example

Metric Tons = d^4 * k / h^2

Metric Tons = ?

d = 5

h = 13

k = 648

Metric Tons = 5^4 * 648 / 13^2

Metric Tons = 625 * 648 / 169

Metric Tons = 2396 rounded.

Step-by-step explanation:

Given the equation representing the pathway of sam's dive into the swimming pool, his height after two seconds is -22ft.

Quadratic equation is simply an algebraic expression of the second degree in x. Quadratic equation in its standard form is;

ax² + bx + c = 0

Where x is the unknown

Given the data in the question

Now, to get the height after 2 seconds, we substitute 2 for t in the equation.

h = -16t² + 15t + 12.

If t = 2

h = -16(2)² + 15(2) + 12

h = -16(4) + 30 + 12

h = -64 + 30 + 12

h = -64 + 42

h = -22ft

Therefore, given the equation representing the pathway of sam's dive into the swimming pool, his height after two seconds is -22ft.

Answer:

answer is 5.7

Step-by-step explanation:

Under Ryan's cell phone plan, he pays a flat cost of $68.50 per month and $5 per gigabyte. With a budget of $92.50, he can use up to 4 gigabytes of data.

Use the concept of subtraction defined as:

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that,

Ryan's flat cost per month is $68.50.

He pays $5 per gigabyte of data.

Ryan wants to keep his bill at $92.50 per month.

We know that Ryan pays a flat cost of $68.50 per month,

so subtract that from his budget:

$92.50 - $68.50 = $24.

Since Ryan pays $5 per gigabyte,

Divide the remaining budget ($24) by the cost per gigabyte ($5) to find out how many gigabytes he can use:

$24 / $5 = 4.8 gigabytes.

Therefore,

Ryan can use up to 4.8 gigabytes of data and still stay within his budget. Keep in mind that any fraction of a gigabyte will be rounded down,

So he can use a maximum of 4 gigabytes.
