What is the selling price of a TV that costs $350 with a 155% markup?

Answer:

±2√10

Step-by-step explanation:

Given the equation 40 - x^2 = 0

Add x^2 to both sides

40 - x^2 + x^2 = 0+ x^2

40 = x^2

x^2 = 40

x = ±√40

x = ±√4 * √10

x = ±2√10

Hence the value of x is ±2√10

Answer:

XZ = 2.5 BD

Step-by-step explanation:

Comparing the two triangles,

[tex]\frac{BD}{BC}[/tex] = [tex]\frac{XZ}{XY}[/tex]

[tex]\frac{6}{8}[/tex] = [tex]\frac{XZ}{20}[/tex]

⇒ XZ = [tex]\frac{20*6}{8}[/tex]

         = 15

XZ = 15

So that,

BD:XZ = 6:15

           = 1:2.5

Therefore, the relationship between BD and XZ is XZ = 2.5 BD.

Answer: volume = 5.5625 cubic units.

Step-by-step explanation:

A rectangular prism is filled with 356 cubes, then the volume of the prism will be equal to 356 times the volume of a single cube.

We know that for a cube with side length L, the volume is:

V = L^3

And we know that these small cubes have an edge length of 1/4 units.

Then the volume of each small cube is:

V = (1/4)^3 cubic units

V = (1/64) cubic units

And the volume of the prism will be 356 times that, then the volume of the prism is:

volume = 356*(1/64) cubic units

volume = 5.5625 cubic units.

Answer:

n = 2

Step-by-step explanation:

-1 + 3 = 2

Answer:

D

Step-by-step explanation:

This equation is in factored form. Meaning you can find the x intercepts of the graph from it. All you need to do is find reverse the numbers inside the parentese. So if its negative, make it positive, if its positive, make it negative. By doing this, you should find that the x-intercepts of this graph are 2 and 3 and the donly graph with x-intercepts at these places is graph d.

Answer:

35

Step-by-step explanation:

You have 17 either side to make 18 the middle e.g if 2 was the middle then you have 1 either side.

Answer:

36

Step-by-step explanation:

if 18 is the middle there are 17 on each side of that person so 17+17+1=36

Answer:

25%

Step-by-step explanation:

30/40 = 0.75 = 75% paid

100-75 = 25% discount

Answer:

[tex]25\%[/tex]

Step-by-step explanation:

To find the discount of an object, one must set up the equation, the difference between the original and the paid price, over the original price, equals percent over 100. In essence;

[tex]\frac{(original-paid)}{original}=\frac{percent}{100}[/tex]

Substitute in the given values;

[tex]\frac{(40)-(30)}{40}=\frac{percnet}{100}[/tex]

Solve;

[tex]\frac{10}{40}=\frac{percent}{100}[/tex]

Simplify,

[tex]\frac{1}{4}=\frac{percent}{100}[/tex]

Cross products,

[tex]100 = 4(percent)[/tex]

Inverse operations,

[tex]100=4(percent)\\/4\\\\25 = percent[/tex]

Answer:

The answer is "x + 4x = 35; 7 large stones and 28 small stones"

Step-by-step explanation:

Please find the complete question in the attached file.

Let

[tex]x = \text{big stone number}\\\\y = \text{tiny stone number}\\\\x + y= 35[/tex]

Users want to use four small stones for each big stone:

[tex]Y = 4x[/tex]

solving the equations system:

[tex]x + y = 35\\\\y = 4x[/tex]

we find:

[tex]x = 7 \ \text{for big stones}\\\\y = 28\ \text{for tiny stones}\\\\[/tex]

Answer:

25

Step-by-step explanation:

Add 65+40 which is going to give you 105 then once you get 105 subtract 65-40 which is going to give you 25 the 105 is the total so the whole answer is 25

Answer:

  523.6 km

Step-by-step explanation:

Let x represent the distance traveled by train. Then 1020-x is the distance traveled by bus. The travel times are given by the relation ...

  time = distance/speed

Then the total travel time in hours is ...

  x/160 +(1020-x)/105 = 8

  21x +32640 -32x = 26880 . . . . .  multiply by 3360

  5760 = 11x . . . . . . . . . add 11x -26880

  523.6 ≈ x . . . . . . . . . . divide by 11

Aidan traveled about 523.6 km by train.

Answer:

167.6 units^3

Step-by-step explanation:

Find the volume of the entire cone, and then divide the result by 4 to obtain the volume of the quarter cone:

Formula for the volume of a cone is V = (1/3)(base area)(height)

In this case the volume of the entire cone is V = (1/3)(pi)(8)^2*(10), or

670.21.

Taking 1/4 of this, we get the volume of the quarter cone:

670.21/4 = 167.6 units^3

Answer:

180

Step-by-step explanation:

Given :

the number has three digits

it is multiple of 20

hundreds digit and tens digit add to make 9

half of it is less than 100.

I suppose 180 can correctly fit into all above criterions

It is 3 digit number. 1+8 =9, 180/2 =90 which is less than 100.
