Q11 The price of a smartphone is $600 and a smart watch is $250. If you buy them together you get a discount of 20%. If you decide to buy both, how much will you end up paying?

Q12Another store is offering the smart watch for $100 if purchased with the smartphone. Is this a better deal than the previous one (Q11)?

Answer:

It's the last one (-3m^-3n)

Step-by-step explanation: You can take this equation and divide it up into parts. To make this simple, make it...

-9/3 × m/m^4 × n²/n

m/m^4 is basically [tex]m^{1-4}[/tex], which ends up being m^-3.

n²/n is basically [tex]n^{2-1}[/tex] which ends up being n^1, or just n.

Then simplify all parts of the equation so you are left with:

-3 × m^-3 × n

You are then left with the bottom answer.

Answer:

3x^3−9x−18

Step-by-step explanation:

Let's simplify step-by-step.

x3+2x3−9x−18

=x3+2x3+−9x+−18

Combine Like Terms:

=x3+2x3+−9x+−18

=(x3+2x3)+(−9x)+(−18)

=3x3+−9x+−18

Answer:

=3x^3−9x−18

Step-by-step explanation:

I have this fancy calculator that can graph stuff… so I put it in my calculator, and compared the graph… y axis in graph 1 was +2 and y axis in graph 2 is -2

Also the graph in function 2 is steeper as it is going from 2 to 2

Distance between points (-3,1) and (2,-1)=6.5

Explanation:

If x is the side length of a cube, then x^3 is the volume. Think of it like length*width*height, but length = width = height.

It's no coincidence that the cubing operation or cubed exponent ties directly to the concept of things like volumes in cubic cm.

In this case, x = 12 cm is the side length of each small cube. The volume of each small cube is x^3 = 12^3 = 12*12*12 = 1728 cubic cm.

Eighty such small cubes get us a total volume of 80*1728 = 138,240 cubic cm.

Answer:

The answer is c, d and e

Step-by-step explanation:

Answer: 13 cm^3

Step-by-step explanation:

The volume of a rectangular prism is the height*width*length.

3 1/4 as a decimal is 3.25.

Now we can plug in the given values into the formula for the volume.

Therefore, the volume = 3.25 cm * 4 cm * 1 cm

= 13 cm^3

Answer:

the anwser is 16 1/4 cm

Answer:

A. 108 in^2

B. 144 in^2

C. 36 in^2

Step-by-step explanation:

Triangle pyramid:

4 times the area of ​​the triangle, since they are equal. We know that the height is 9 inches and that the base is 6 inches, so the area of ​​the triangle is the multiplication of the base times the height divided by two. Then:

At = b*h/2

At = 6*9/2

At = 27

27 square inches would be the area of ​​one single triangle, but since there are 4 it would be 4*27=108 square inches.

For a triangular-based pyramid it would take 108 square inches of paper.

Square- pyramid:

It would be 4 times the area of ​​the triangle, since we assume that they are equal. Adding the base of the pyramid, that would be the area of ​​a square. The area of ​​the square is equal to the base times the base or base to the square.

In other words, the total area above would be 108 square inches adding the area of ​​the square. So

As=b*b

Ace=6*6

Ace=36

Therefore the final area would be 108+36=144 square inches.

For a Quadratic pyramid it would take 144 square inches of paper.

The difference between one and the other is 36 square inches, which is equivalent to the square base of the square pyramid.

Answer:

$35,000

Step-by-step explanation:

if you look at the bottom it says years of experience, and the side says income (emphasis on in thousands) so each of the numbers on the side are in the thousands so all you have to do, is go to the 10 on the bottom, and follow the line up to where you see a dot then go over to the left and find the number that the dot corresponds to which is your answer. $35000

Answer: 1620 in.^3

Step-by-step explanation: Basically, you have a prism that has a base of 180, and a height of 9 in. The volume of a rectangular prism is length*width*height, and 180 is the length*width, so to find the answer, you do 180*9, which is equal to 1620.

Answer:

They are not proportion because their product are not equal.

First part

   [tex]6x + blank = 10\\blank = 10 - 6x[/tex]

 Thus the first part's blank should be filled in with 4x

Second part

   [tex]6x-(blank)= 4x -10\\-(blank) =4x - 10 - 6x\\-(blank) = -2x -10\\blank = 2x + 10[/tex]

Thus the second part's blank should be filled in with 2x + 10

Hope that helps!

Explanation:

Let's go over an example.

We'll have a = 1 and b = 7 which makes a < b true. Feel free to pick your own favorite pair of numbers such that b is larger than 'a'.

The corresponding opposites are:  -a = -1 and -b = -7

The relationship flips because the opposites of each number are flipped. So instead of saying -a < -b, we have -a > -b

Sure enough, -1 > -7 is a true statement. Use a number line to see this. I recommend a vertical number line.

In short, going from a < b to -a > -b means we flip the signs of each term, and we flip the inequality sign as well.
