A old computer model that cost $599(whole) is marked down 5%. How much money will the customer save (what is the discount only)?

Answer:

1. X^2+1/2x = [tex]x(x+\frac{1}{2})[/tex]

2.  X^2+2x-3 = [tex](x-1)(x+3)[/tex]

3. (2x-3)^2 = (2x-3)(2x-3)

4. X^3+2x^2-19x-20 = [tex](x+1)(x-4)(x+5)[/tex]

Step-by-step explanation:

Each expression can be written as a product of linear factors as follows

1. X^2+1/2x ⇒ [tex]x^{2} + \frac{1}{2}x[/tex]

[tex]x^{2} + \frac{1}{2}x[/tex] = [tex]x(x+\frac{1}{2})[/tex]

Hence,  X^2+1/2x = [tex]x(x+\frac{1}{2})[/tex]

2. X^2+2x-3 ⇒ [tex]x^{2} +2x-3[/tex]

[tex]x^{2} +2x-3 = x^{2} +3x-x-3[/tex]

[tex]x^{2} +3x-x-3 = x(x+3) -1(x+3)[/tex]

[tex]x(x+3) -1(x+3) = (x-1)(x+3)[/tex]

Hence,  X^2+2x-3 = [tex](x-1)(x+3)[/tex]

3. (2x-3)^2 ⇒[tex](2x-3)^{2}[/tex]

[tex](2x-3)^{2} = (2x-3)(2x-3)[/tex]

Hence, (2x-3)^2 = (2x-3)(2x-3)

4. X^3+2x^2-19x-20 ⇒ [tex]x^{3}+2x^{2} -19x -20[/tex]

[tex]x^{3}+2x^{2} -19x -20 = (x+1)(x^{2} +x-20)[/tex]

First,

[tex]x^{2} +x-20 = x^{2} +5x-4x-20\\x^{2} +5x-4x-20= x(x+5)-4(x+5)\\x(x+5)-4(x+5) = (x-4)(x+5)[/tex]

∴ [tex](x+1)(x^{2} +x-20) = (x+1)(x-4)(x+5)[/tex]

Hence, X^3+2x^2-19x-20 = [tex](x+1)(x-4)(x+5)[/tex]

Answer:

some of interior angles of hexagon = 720°

therefore,

720 = 121 + 96 + 101 + 162 + 90 + x

720 = 570 + x

729 - 570 = x

150 = x

Answer:

A) = 4.

B) = 25.

C) = 4.

Step-by-step explanation:

We are given that a and b are positive integers and that:

[tex]a-b=2[/tex]

And we want to evaluate the following expressions.

Expression A)

We have:

[tex]\displaystyle \frac{2^a}{2^b}[/tex]

This is equivalent to:

[tex]=2^a\div 2^b[/tex]

Therefore:

[tex]=2^{a-b}[/tex]

Substitute and evaluate:

[tex]=2^{(2)}=4[/tex]

Expression B)

We have:

[tex]\displaystyle \frac{5^a}{5^b}[/tex]

This is equivalent to:

[tex]=5^{a-b}[/tex]

Again, substitute and evaluate:

[tex]=5^{(2)}=25[/tex]

Expression C)

Lastly, we have:

[tex]\displaystyle \frac{4^{0.5a}}{2^b}[/tex]

Note that 4 = 2². Hence:

[tex]=\displaystyle \frac{(2)^{2(0.5a)}}{2^b}[/tex]

Simplify:

[tex]=\displaystyle \frac{2^a}{2^b}[/tex]

Using the previous result:

[tex]=4[/tex]

Answer:

3.6

Step-by-step explanation:

To find the distance of two points you use the formula [tex]\sqrt{x2-x1)^{2} +(y2-y1)^{2} }[/tex]

so all we have to do is plug in the x's and y's

the points given are (-8,6) and (-5,8) so  we would do

[tex]\sqrt{(-5-(-8))^{2} +(8-6)^{2} }[/tex]

if you plug that into a calculator you get that the distance between the two points are 3.605551275

but you would just want to round to the nearest tenth so the distance between the two points are 3.6

hope this helps and if you have nay questions lmk :D

Answer:

x=20

Step-by-step explanation:

so we just mark ADB as 45 and BDC as 50 and now we can find B and C by doing 180-50=130/2 so B=65 and C=65 now we have 2 angles so we can find x. D is 95 bc we add 45 and 50 and C is 65 like i wrote there so we add 95+65 and get 160 and we subtract 160 from 180 to get x=20

Answer:

4.8

Step-by-step explanation:

because if 2 can't go into 3 time than what

Divisibility rule of 2-last digit divisibility

Divisibility rule of 3-sum of digit divisibility

Divisibility rule of 4-last 2 digits divisibility

Divisibility rule of 5-last digit 0 or 5

Divisibility rule of 6-divisible by both 2 and 3

Divisibility rule of 9-sum of digits divisibility

Divisibility rule of 10-last digit 0

Now we can see that last digit 6 is divisible by 2

2+6+1+6=15 is divisible by 3

16 is divisible by 4

6 is not 0,5 so 2616 is not divisible by 5

2616 divisible by both 2 and 3 so its divisible by 6

2+6+1+6=15 is not divisible by 9

6 is not 0 so 2616 is not divisible by 10

Hope it helped!

Answer:

The wire is sufficient for making a cube of volume 2197 cm³

Step-by-step explanation:

Volume of cube = L³

Volume of the cube = 2197 cm³

Length of the wire = 150 cm

Let's see if the wire is sufficient for making a cube.

Volume of the cube that could be made from the wire is:

V = (L)³

V = (150)³

V = 3,375,000 cm³

So,

The volume of the cube using a 150 cm length wire is much more grater than 2197 cm³.

That is why, the wire is sufficient for making a cube of volume 2197 cm³.

Answer:

Each term in Pattern A is equals to 6 times the value of corresponding term in Pattern B and subtract 12

Step-by-step explanation:

Given - Pattern A: start with 12 and add 12

             Pattern B: start with 4 and add 2

To find - Which statement best describes the relationship between the

              corresponding terms of Patter A and Pattern B.

Proof -

To find the relationship between the Pattern a and pattern B , firstly we have to find few terms of both the Patterns , so that we can see how the digits of both the Patterns are realted

Now,

For Pattern A :

1st digit = 12

2nd digit = 12 + 12 = 24

3rd digit = 24 + 12 = 36

4th term = 36 + 12 = 48

5th term = 48 + 12 = 60

.

.

.

and so on

Now,

For Pattern B :

1st digit = 4

2nd digit = 4 + 2 = 6

3rd digit = 6 + 2 = 8

4th term = 8 + 2 = 10

5th term = 10 + 2 = 12

∴ we get

Terms of Pattern A : 12, 24, 36, 48, 60, ....

Terms of Pattern B :  4, 6, 8, 10, 12, ....

As we can see that

4×6 - 12 = 12

6×6 - 12 = 24

8×6 - 12 = 36

10×6 - 12 = 48

12×6 - 12 = 60

.

.

The pattern is - Multiply by 6 in Pattern B and after that subtract by 12 , we get Pattern A.

Term in Pattern A = 6×corresponding term of Pattern B - 12

i.e. , we get

Each term in Pattern A is equals to 6 times the value of corresponding term in Pattern B and subtract 12

Given:

A figure.

To find:

The area of the figure.

Solution:

Draw a line and divide the figure it two parts as shown in the below figure.

From the figure it is clear that the line divides the given figure it two rectangles with dimensions 3 yd by 4 yd and 4 yd by 7 yd.

Area of a rectangle is

[tex]Area=Length\times width[/tex]

Using this formula, the areas of both rectangles are

[tex]A_1=3\times 4[/tex]

[tex]A_1=12[/tex]

And,

[tex]A_2=7\times 4[/tex]

[tex]A_2=28[/tex]

Now, the area of combined figure is

[tex]A=A_1+A_2[/tex]

[tex]A=12+28[/tex]

[tex]A=40[/tex]

Therefore, the area of given figure is 40 sq yd.
