Answer:

x = 11

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

5x + 4 + 6x - 3 + 4x + 14 = 180 ← collect like terms on left side

15x + 15 = 180 ( subtract 15 from both sides )

15x = 165 ( divide both sides by 15 )

x = 11

Hope this help!!!

Have a nice day!!!

Answer:

Central angle = 98 degrees

Step-by-step explanation:

Radius (r) = 10 Arc length = 49[tex]\pi[/tex]/9

Let 0 be the central angle

Arc Length = 2[tex]\pi[/tex]r0/360

49[tex]\pi[/tex]/9 = 2[tex]\pi[/tex]r0/360

49[tex]\pi[/tex]/9 = [tex]\pi[/tex]x0/18

49[tex]\pi[/tex]/9 x 18/[tex]\pi[/tex] = 0

0 = 49x2

0 = 98 degrees

Answer:

P= $29  and D = -$30

Step-by-step explanation:

4D + 5P = $25

5P = $25 - 4D

P = ($25 - 4D)/5            equation(i)

Noe substitute the value of P

3D + 4P = $26

3D + 4($25 -4D)/5 = $26

3D*5 + ($100 -16D)/5 =$26*5

15D + $100 - 16D =$130

-D = $130 - $100

D = -$30

Again substitute the vale of D in equation(i)

P = ($25 + 4D)/5

=$25 + 4*$30/5

=$25 + $120/5

=-$145/5

=$29

Answer:

P = 29, D = - 30

Step-by-step explanation:

Given the 2 equations

4D + 5P = 25 → (1)

3D + 4P = 26 → (2)

Multiplying (1) by 3 and (2) by - 4 and adding the result will eliminate D

12D + 15P = 75 → (3)

- 12D - 16P = - 104 → (4)

Add (3) and (4) term by term to eliminate D

0 - P = - 29

- P = - 29 ( multiply both sides by - 1 )

P = 29

Substitute P = 29 into either of the 2 equations and solve for D

Substituting into (1)

4D + 5(29) = 25

4D + 145 = 25 ( subtract 145 from both sides )

4D = - 120 ( divide both sides by 4 )

D = - 30

The total tax is 8 dollars and 60 cents

Answer:

$153.70

Step-by-step explanation:

Sales tax is applied to things that are sold by a retailer. So if it says 6% tax is levied on the item, that means the total cost will be the initial cost of skateboard ($145) + sales tax (6% of 145)  = 145 + 8.7 = $153.70

Answer:

1.) At times, designing a good structure with a specific function may often be difficult. If the structure is not well-designed or strong enough for the function it will not properly work. So in order for the design to be well-built, both the structure and function must cooperate.

2.) Symmetry is a balanced arrangement on the opposite sides of a structure. In order for for a structure to be stable and properly work without complications, it most commonly needs to be symmetrical. This is a very important part of designing a structure.

3.) If the structure cannot withstand the function nor the possible forces that it may encounter. It is likely that it will break or even be completely destroyed.

4.) Shape, line, color, texture, movement, space. The designer may have taken into consideration whom the desk may be used by for the shape and space. Color, texture, and line may have been based on the environment (ex. A carpenter, student, computer desk) it would be in. Although the designer may not have an exact knowledge of where the desk would be, he still could consider what the desk could "possibly" be used for. Once again, the designer could take into consideration the user, for the movement of the desk. If the desk was to be moved around on wheels, or possibly could even fold. The designer must take into consideration EVERY detail.

6.) When people design something, often times you do not know how well that design is going to work without testing it with a prototype. Yes, prototypes are expensive. Yet, if they were to build something without testing their design, something may be wrong with it. So as a result, you will spend more money manufacturing something with a defect than testing it with a prototype.

For question 5, I think it might be best if you answer that one. It is based on YOUR opinion and what YOU use. If you are asked about it, they will know it's from you and your opinion. Lol! But I hope I helped you out with the other questions! ;)

Answer:

[tex]x = \frac{16}{3} [/tex]

Step-by-step explanation:

Solve the equations:

[tex]4x \: 2 - 5x = 16[/tex]

Multiply the monomals:

[tex]8x - 5x = 16[/tex]

Combine like terms:

[tex]3x = 16[/tex]

Divide both sides of the equation by the coefficient of variable:

[tex]x = 16 \div 3[/tex]

Calculate:

[tex]x = \frac{16}{3} [/tex]

Given:

The data table is given.

The equation of trend line is:

[tex]y=2x+15[/tex]

To find:

Values for residual table.

Solution:

Formula for residual:

[tex]Residual=\text{Observed value}-\text{Predicted value}[/tex]

The equation of trend line is:

[tex]y=2x+15[/tex]                ...(i)

Substituting [tex]x=5[/tex] in (i), we get

[tex]y=2(5)+15[/tex]

[tex]y=10+15[/tex]

[tex]y=25[/tex]

The value of y from the table at [tex]x=5[/tex] is 25. So,

[tex]Residual=25-25[/tex]

[tex]Residual=0[/tex]

Similarly,

Substituting [tex]x=6[/tex] in (i), we get

[tex]y=2(6)+15[/tex]

[tex]y=12+15[/tex]

[tex]y=27[/tex]

The value of y from the table at [tex]x=6[/tex] is 28. So,

[tex]Residual=28-27[/tex]

[tex]Residual=1[/tex]

Substituting [tex]x=7[/tex] in (i), we get

[tex]y=2(7)+15[/tex]

[tex]y=14+15[/tex]

[tex]y=29[/tex]

The value of y from the table at [tex]x=7[/tex] is 29. So,

[tex]Residual=29-29[/tex]

[tex]Residual=0[/tex]

Substituting [tex]x=8[/tex] in (i), we get

[tex]y=2(8)+15[/tex]

[tex]y=16+15[/tex]

[tex]y=31[/tex]

The value of y from the table at [tex]x=8[/tex] is 30. So,

[tex]Residual=30-31[/tex]

[tex]Residual=-1[/tex]

Substituting [tex]x=9[/tex] in (i), we get

[tex]y=2(9)+15[/tex]

[tex]y=18+15[/tex]

[tex]y=33[/tex]

The value of y from the table at [tex]x=9[/tex] is 32. So,

[tex]Residual=32-33[/tex]

[tex]Residual=-1[/tex]

Therefore, the complete residual table is:

x                 :          5            6             7             8             9

Residuals  :          0             1             0             -1            -1

Answer:

  (b)  36 in²

Step-by-step explanation:

The right triangle at lower right has a vertical leg of 3 and a hypotenuse of 5. Then the horizontal leg is ...

  √(5² -3²) = √16 = 4

Then the horizontal diagonal is 4+4 = 8. The vertical diagonal is 6+3 = 9. The area is half the product of the diagonals, so is ...

  A = 1/2(d1)(d2) = 1/2(8 in)(9 in) = 36 in²

__

You could figure the areas of the triangles separately, but you would come to the same result. This formula is good for a rhombus or a kite (or a square, which is also a rhombus), because the diagonals are perpendicular to each other.

Answer:

y = -1/4 x+11/16

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = -1/4x+b

Substitute the point in for x and y

1 = -1/4(-5/4) +b

1 = 5/16 +b

16/16 = 5/16 +b

Subtract 5/16 from each side

11/16 = b

y = -1/4 x+11/16

Answer:

y = - [tex]\frac{1}{4}[/tex] x + [tex]\frac{11}{16}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - [tex]\frac{1}{4}[/tex] , then

y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation

To find c substitute ( - [tex]\frac{5}{4}[/tex], 1 ) into the partial equation

1 = [tex]\frac{5}{16}[/tex] + c ⇒ c = 1 - [tex]\frac{5}{16}[/tex] = [tex]\frac{11}{16}[/tex]

y = - [tex]\frac{1}{4}[/tex] x + [tex]\frac{11}{16}[/tex]

Answer:

f(x) = (x + 20)(x - 24)(x + 10)(x + 12)

Step-by-step explanation:

This is an equation of degree 4 and as the beginning of the graph descends from negative x the polynomial will have a positive leading coefficient. The graph is roughly W shaped.

It also has zeroes at x = -20,-12 ,-10 and x = 24.

So it is the first option.
