Answer:

  b, c, d, e, f

Step-by-step explanation:

x ∉ A  . . . . .  not true, x is in A

x ∈ B . . . true

x ∉ C . . . true (x is outside the circle labeled C)

x ∈ A ⋃ B . . . true

x ∈ A ⋃ C . . . true

x ∈ A ⋂ B . . . true (x is in the overlap)

Answer:

A is false, every thing else is correct so b,c,d,e,f is your answer

Answer:

x= -8, 9 1/4

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Answer:

-1

Step-by-step explanation:

-12 + 2t = -14

12 + -12 + 2t = -14 + 12

2t = -2

2t/2 = -2/2

t = -1

Answer:

  (-5.5, -1.5)

Step-by-step explanation:

The midpoint is the average of the end points:

  ((-7, -5) +(-4, 2))/2 = (-7-4, -5+2)/2 = (-11, -3)/2 = (-5.5, -1.5)

The midpoint of the segment is (-5.5, -1.5).

28^2=784

29^2=841

784<830<841

therefore sqrt784<sqrt830<sqrt841

therefore 28<sqrt830<29

Done!

Answer:

37.5%

Step-by-step explanation:

Labor rate = 8.75 dollars per hour.  

Hours worked = 6

Direct cost of labor = 140 dollars

Total price of services = 224 dollars

Therefore, the overheads = 84 dollars which is

84 X 100 / 224 = 37.5%

Answer:

x = 110°

Step-by-step explanation:

∠ QRS = ∠ YRT = 110° ( vertically opposite angles )

∠ PQR = 180° - 120° = 60° ( adjacent angles )

The sum of the interior angles of a quadrilateral = 360°

Sum the angles and equate to 360°, that is

110 + 60 + x + 80 = 360

250° + x = 360° ( subtract 250° from both sides )

x = 110°

Answer:

x = 3 x = -4

x = 1 x = 8

Step-by-step explanation:

x² + x - 12

(x + 4) (x - 3)

x + 4 = 0

x = - 4

-----------

x - 3 = 0

x = 3

x² - 9x + 8

(x - 8) (x - 1)

x - 8 = 0

x = 8

-----------

x - 1 = 0

x = 1

Answer:

angle BAD = 180 -2x

angle BCD = x                                                    given

angle BCD is an inscribed angle                      

angle DOB = 2 (angle BCD)                              

angle BAD = 180 -angle DOB                           2 tangent theorem      

Step-by-step explanation:

Answer:

[tex] m\angle BAD= (180 - 2x)\degree [/tex]

Step-by-step explanation:

[tex] m\widehat {BD} =2\times m\angle BCD[/tex]

(By inscribed angle theorem)

[tex] m\widehat {BD} =2x\degree [/tex]

[tex] m\widehat {BCD} =360\degree - m\widehat {BD}[/tex]

(By arc sum property of a circle)

[tex] m\widehat {BCD} =360\degree - 2x\degree [/tex]

[tex] m\angle BAD=\frac{1}{2} (m\widehat {BCD}-m\widehat {BD}) [/tex]

(by property of intersecting tangents outside of the circle)

[tex] m\angle BAD=\frac{1}{2} [(360\degree - 2x\degree) -2x\degree] [/tex]

[tex] m\angle BAD=\frac{1}{2} (360\degree - 2x\degree -2x\degree) [/tex]

[tex] m\angle BAD=\frac{1}{2} (360\degree - 4x\degree) [/tex]

[tex] m\angle BAD=\frac{1}{2} \times 2(180\degree - 2x\degree) [/tex]

[tex] m\angle BAD= (180 - 2x) \degree [/tex]

Step-by-step explanation:

 Math Problems                   3              15

 ----------------------                  -----     =    ------

       Minutes                          8              x

                                             3x = 15 * 8

                                               x = 15 * 8 / 3

                                               x = 120 / 3

Answer

y = 3/2x -8

Step-by-step explanation:

The first thing you should do is change the equation into slope intercept form. Subtract 2x from both sides to get: 3y = -2x + 18. Divide all parts of the equation by 3 to get your equation in slope intercept: y = -2/3x + 6. One thing you should know when finding the slope of a perpendicular line is that it is the opposite reciprocal. So, the slope is going to be 3/2. This is your current equation: y = 3/2x + b. Plug in the point to the equation, it should look like this: 1 = 3/2(6) + b. Multiply 3/2 by 6 to get 9. This is what it should look like: 1 = 9 + b. Then, subtract 9 from both sides of the equation to get your y-intercept of -8. Go back to your other equation and plug in -8 for b. This is your final equation: y = 3/2x -8.

Answer:

B. 11k + 16

Step-by-step explanation:

We have an expression and are asked to combine like terms.

To solve this, we need to first distribute 4(k + 4). Which is to multiply four by both k and 4.

(4(k) + 4(4))

4k + 16

7k + 4k + 16.

Since 7k and 4k are like terms since they end in the same variable, we can only add them.

7 + 4

11

11k + 16

Answer:

Let's use the slope-intercept form of the equation of a line describe the slope and the y-intercept:
