Answer:

$3,240

Step-by-step explanation:

The computation of the money that have to be paid by the shopkeeper to the manufacture is shown below:

Given that

the sale price of television is $2,700

And, the profit is of 20%

So, the price paid is

= $2,700 + $2,700 × 20%

= $2,700 + $540

= $3,240

The approximate volume of a cone with the same diameter and height as the cylinder is 131.95 cm³.

In Mathematics and Geometry, the volume of a cylinder can be calculated by using this formula:

Volume of a cylinder, V = πr²h

Where:

Radius = diameter/2 = 6/2 = 3 cm.

By substituting the given parameters into the volume of a cylinder formula, we have the following;

Volume of cylinder, V = π × 3² × 14

Volume of cylinder, V = π × 9 × 14

Volume of cylinder, V = 395.8 cm³.

For the volume of this cone, we have:

Volume of cone, V = 1/3 × πr²h

Volume of cone, V = 1/3 × 395.8

Volume of cone, V = 131.95 cm³.

Answer:

The correct options that describe the inequality (y + 1)² > 6·(x - 2)

1) Because only the 'y' quantity is squared the curve is a parabola

2) The parabola opens right because 6 is in front of the 'x' quantity

3) The shading area is outside the parabola because (0, 0) satisfies the inequality

4) The values subtracted from 'x', and 'y' in the equation are the coordinates of the vertex

Step-by-step explanation:

The given inequality graphed by Miranda is presented as follows;

(y + 1)² > 6·(x - 2)

By simplification, we get;

Given that the inequality is of the form (y - k)² > 4·p·(x - h), we have;

The curve is a parabola as only the 'y' quantity is squared

-k = 1

∴ k = -1

4·p = 6

∴ p = 6/4 = 3/2 = 1.5

p = 1.5

-h = -2

∴ h = 2

The vertex of the parabola = (h, k) = (2, -1)

The axis of symmetry = The x-axis

p = 1.5 > 0, therefore, the parabola opens right

Therefore, the parabola opens right because 6 is in front of the 'x' quantity

There is a strict inequality therefore the boundary is not included in the solution set

When x = 0 and y = 0, we have;

(y + 1)² > 6·(x - 2)

(0 + 1)² > 6·(0 - 2)

1² > 6 × (-2)

1 > -12, which satisfies the inequality and (0, 0) is on the left and below the vertex, therefore, the shaded area is outside the parabola

The vertex of the parabola given in the form, (y - k)² > 4·p·(x - h), is (h, k), which are the values subtracted from 'x', and 'y' in the equation

Therefore, the vertex of the given parabola, (y + 1)² > 6·(x - 2) = (2, -1)

Answer: Choice D.  < B = < A

ie, "angle B = angle A"

The symmetric property is if y = x then x = y. The order of what is on the left or right side of the equation does not matter. It's like saying 2+3 = 5 is the same as 5 = 2+3.

This idea can be extended to congruences because congruent angles have the same measure.

So < A = < B is the same as < B = < A.

Answer:

Step-by-step explanation:

15. (-4-3)/(-5-0)= -7/-5= 7/5

      y - 3 = 7/5x - 0

      y = 7/5x + 3

16. (-2-3)/(4-0)= -5/4

     y - 3 = -5/4x - 0

     y = -5/4x + 3

17. (-3+5)/(0+3)= 2/3

    y + 5 = 2/3(x + 3)

     y + 5 = 2/3x + 2

     y = 2/3x - 3

18. (-2-2)/(0+4)= -4/4= -1

       y - 2 = -1(x + 4)

       y - 2 = -x - 4

       y = -x - 2

19. y - 3 = 1/2x - 0

     y = 1/2x + 3

20. y - 2 = -(x + 1)

      y - 2 = -x - 1

      y = -x + 1

21. perp. -5/3

y + 5 = -5/3x  + 0

 y = -5/3x - 5

22. perp. 1/2

   y + 1 = 1/2(x + 4)

   y + 1 = 1/2x + 2

   y = 1/2x + 1

23. perp. 3/4

   y + 5 = 3/4(x + 4)

   y + 5 = 3/4x + 3

   y = 3/4x - 2

24. perp. 7/5

 y - 4 = 7/5(x - 5)

 y - 4 = 7/5x - 7

 y = 7/5x - 3

Answer:

No solution

Step-by-step explanation:

There are no values of  n  that make the equation true.

8n −2(n+5) = −3 + 6n

First Step: Simplify both sides of the equation

(Distribute) 8n + (-2)(n) + (-2)(5) = -3 + 62

8n + -2n + -10 = -3 + 6n

(Combine like terms) (8n + −2n) + (−10) = 6n − 3

6n + −10 = 6n − 3

6n  − 10 =  6n − 3

Step 2: Subtract 6n from both sides

6n − 10 − 6n = 6n − 3 − 6n

-10 = -3

Step 3: Add 10 to both sides

-10 + 10 = -3 + 10

Total rainfall in one month [tex]0.9167[/tex] inches

Step-by-step explanation:

The total rainfall around an year is equal to  [tex]11[/tex] inches

There are 12 months in an year.

Total rainfall in one month is equal to total rainfall in an year divided by number of months

Total rainfall in one month

[tex]\frac{11}{12} = 0.9167[/tex] inches

Answer:

D

Step-by-step explanation:

Let x = total number of basketball games that was played by the team this season.

Alon started in 60% of his team’s basketball games this season. This means that he started in a total number of 60 percent of x basketball games this season.

60% of x basketball games this season = 60/100 × x

= 0.6×x = 0.6x

From the information given, Alon started a total of 12 basketball games this season. Therefore,

0.6x = 12

x = 12/0.6 = 20

The width of the rectangle represented by the expression (x⁴ – 64)/x.

A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.

Given:

The length of a rectangle is 16 units more than its width.

Let the length is x units.

Then width = (x + 16) units.

The area of the rectangle can be expressed as

x⁴ – 64 = length x width

x⁴ – 64 = x (x + 16)

x + 16 =(x⁴ – 64)/x

Therefore, the width expression is (x⁴ – 64)/x.
