Answer 1

Answer:

white

4 were sold

3 more gray were sold than white

3 colors sold 10 or more

Answer 2

Answer:

a) White

b) 3

c) 3

Step-by-step explanation:

a) White as it is the shortest bar (has the lowest height and only has 4 t-shirts sold)

b) According to the bar graph, 7 grey t-shirts were sold and 4 white t-shirts were sold. Subtracting 4 from 7 = 7-4 = 3

Hence, 3

c) At least 10 T-shirts sold, suggests that it was greater than or equal to 10. According to the graph, black has 12, tan has 11, and brown has 10. Hence,

3 colors had at least 10 t-shirts sold.

Aman bought a computer for 24000 and its accessories pack worth for 1750. He sold it all for *26780. Find his gain and gain per cent.​

Answers

Answer:

4%

Step-by-step explanation:

Gain percentage = 1030/25750 x 100 = 4%

Answer:

$1,030, 4%

Step-by-step explanation:

Aman spent $25,750 on a computer and accessory packs (totally worth it). He sold it for $26,780. So let's say Aman is at 0 before he bought this. He spent $25,750, so we subtract that from 0 to get -25,750. Then he sells it all for $26,780 (again totally worth it for the person buying). So we add 26,780 to the total.

-25,750 + 26,780 = 1,030

So Aman made a profit of $1,030 (now he can buy a REASONABLY priced MacBook Air or something)

So to find the percentage that he gained, we divide 1,030 by his original spending price, namely 25,750

1,030/25,750 = 0.04

Convert that to percentage form, you get 4%

Answers

Answer:

208 ft^3

Step-by-step explanation:

Let the plane through the 4 ft X 4ft square at the top of the figure break the figure into 2 boxes, one has dimensions (8-7) by 3 by 4 = 1ft X 3ft X 4ft, and the other has dimensions 7 by 7 by 4 = 7ft X 7ft X 4ft.

They have volumes of (1)(3)(4) = 12 ft^3, and (7)(7)(4) = 196 ft^3, respectively, so the total volume = 12 + 196 = 208 ft^3, the answer.

Answer:

Step 1 :Equation at the end of step 1

 ((81•(x4))-((72•(x2))•(y2)))+24y4

Step 2 :

Equation at the end of step 2 :

 ((81 • (x4)) -  ((23•32x2) • y2)) +  24y4

Step 3 :

Equation at the end of step 3 :

 (34x4 -  (23•32x2y2)) +  24y4

Step 4 :Trying to factor a multi variable polynomial

4.1    Factoring    81x4 - 72x2y2 + 16y4

Try to factor this multi-variable trinomial using trial and error

Found a factorization  :  (9x2 - 4y2)•(9x2 - 4y2)

Detecting a perfect square :

4.2    81x4  -72x2y2  +16y4  is a perfect square

It factors into  (9x2-4y2)•(9x2-4y2)

which is another way of writing  (9x2-4y2)2

How to recognize a perfect square trinomial:  

• It has three terms  

• Two of its terms are perfect squares themselves  

• The remaining term is twice the product of the square roots of the other two terms

Trying to factor as a Difference of Squares:

4.3      Factoring:  9x2-4y2

Put the exponent aside, try to factor  9x2-4y2

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check :  9  is the square of  3

Check : 4 is the square of 2

Check :  x2  is the square of  x1

Check :  y2  is the square of  y1

Factorization is :       (3x + 2y)  •  (3x - 2y)

Raise to the exponent which was put aside

Factorization becomes :   (3x + 2y)2   •  (3x - 2y)2  

Final result :

 (3x + 2y)2 • (3x - 2y)2

A. how many feet does each inch represent? That is, what is the scale?

B. What are the length and width of the living room on the scale and drawing( in inches)?

C. What are the actual length and width of the living room( in feet)?

D. if the family wants to lay carpet in the living room and carpeting cost $1.25 per square foot, how much will carpet cost

Answers

Answer:

See below

Step-by-step explanation:

A)

According to dimensions of the garage, the scale is:

1 in : 20 ft, as the width of the garage is 20 ft and on paper is 1 in

B)

Living room

Dimensions on paper:

2 in x 1 1/4 in

C)

Actual dimensions:

2*20 ft = 40 ft and1 1/4 * 20 ft = 25 ft

D)

The area of the living room:

A = lw = 25*40 = 1000 ft²

Cost of carpet:

1000*$1.25 = $1250

Length

20(2)=40ft

Width

1.25(20)25ft

Area

25(40)1000ft²

Total cost

1000(1.25)$1250

Hope this will help you!! <3

Answer:

Step-by-step explanation:

1) -90 ≥ 18x

Divide both sides by 18

-90/18 ≥ 18x/18

-5 ≥ x

2)x/3 > -8

Multiply by 3,

3*(x/3) > -8*3

x> -24

3)x - 10 < -26

Add 10 to both sides

x  < -26 +10

x < -16

4) 19 -x ≥ 21

Subtract 19 from both sides,

-x ≥ 21 - 19

-x ≥ 2

Divide both sides by (-1)

x < -2

1. given w(x)=4x
a. graph r(x)=4 x w(x). then complete the table of corresponding points on r (x). How do you graph this?

Answers

Answer:

Step-by-step explanation:

a). When graph w(x) is transformed to r(x) = 4 × w(x), graph of w(x) is vertically  stretched by a scale factor of 4.

Table for the corresponding points will be,

x               w(x)                  r(x)

0                0                  0×4 = 0

15              60               60×4 = 240

30             120             120×4 = 480

45             180             180×4 = 720

b). As discussed in part (a), graph of w(x) will be vertically stretched by a scale factor of 4 to produce the graph of r(x).

c). Since, w(x) = 4x

  and r(x) = 4[w(x)]

  r(x) = 4(4x) = 16x

 r(x) = 16x
