Answer:

= -4.41666666667

Step-by-step explanation:

Answer:

    [tex]-7\frac{2}{3} + -5\frac{1}{2} +8\frac{3}{4}\\\\\frac{-23}{3} -\frac{11}{2} + \frac{35}{4}\\\\[/tex]

LCM (3, 2 ,4) = 12

   [tex]\frac{(-23*4) -(11*6)+(35*3)}{12} = \frac{-92-66+105}{12} =\frac{-53}{12} = -4\frac{5}{12}[/tex]

Answer:

67, 600

Step-by-step explanation:

There are 26 alphabet and 10 digits then the number of the possible ID codes will be 67600.

A permutation is an act of arranging the objects or elements in order. Combinations are the way of selecting objects or elements from a group of objects or collections, in such a way the order of the objects does not matter.

A company is making aid badges with personal ID codes on them for each employee.

The ID code will consist of two letters followed by 2 digits.

Then the number of ways ID codes are there will be

[tex]\rightarrow 26 \times 26\times 10\times 10\\\\\rightarrow 67600[/tex]

Answer:

  A, B

Step-by-step explanation:

The equation is equivalent to ...

  cos(x -π/7) = -(√2)/2

  x -π/7 = arccos(-(√2)/2) = {3π/4, 5π/4} . . . . . cosine is negative in QII and QIII

  x = {3π/4 +π/7, 5π/4 +π/7} +2nπ . . . . . matches A and B

Answer:

D. 96 inches.

Step-by-step explanation:

Radius of cylinder = 1/2 * 24 = 12 inches.

Radius of the cone = 1/2 * 12 = 6 inches.

Volume of the cylinder = pi r^2 h and volume of the cone = 1/3 pi r^2 h

So pi 12^2 * 8 = 1/3 pi * 6^2 * h

1152 pi = 12 pi h

h = 1152/12

h = 96 inches.

Answer:

Step-by-step explanation:

we have several angles that have the same vertex and so they are congruent

1) e = 35 degrees because the opp angle has this measure

2) d = 109 degrees for the reason above

3) for find f we have to notice that the sum of the three angles (if you look at the vertical line you can notice that it is a straight line, so describes two angles whose measures are 180 degrees)

f = 180 - (35 + 109)

f = 180 - 144 = 36 degrees

Answer:

50 feet

Step-by-step explanation:

Set up a 3-dimensional coordinate system (see the attached image).

This setup shows an axis that runs North-South (South is negative, North is positive), an axis that runs East-West (East is positive, West is negative), and an axis that runs Up-Down (Up is positive, Down is negative).

The two points in question are then:

First person's location (12, -20, -12), and the second person's location is (-20, 10, 12).

The distance between two points  [tex]\left( x_1,\,y_1,\,z_1\right)[/tex]  and  [tex]\left( x_2,\,y_2,\,z_2\right)[/tex] is

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2[/tex]

[tex]d=\sqrt{(-20-12)^2+(10-(-20))^2+(12-(-12))^2}\\\\d=\sqrt{(-32)^2+30^2+24^2}\\\\d=\sqrt{2500}\\\\d=50[/tex]

Answer:

  9 weeks

Step-by-step explanation:

In problems of this nature, the usual assumption is that the time required is proportional to the work product and inversely proportional to the number of people doing the job. Here, there is no change in the amount of work, but the number of people is reduced by a factor of 12/18 = 2/3.

So, the amount of time required is expected to increase by a factor of 1/(2/3) = 3/2.

  (6 weeks)×(3/2) = 9 weeks

It would have taken 9 weeks to sew the 540 dresses.

Answer:

x =14

<A =  7x -11 =  87

<B = 2x-3 =  25

<C = 5x -2 = 68

Step-by-step explanation:

The sum of the angles add to 180

7x -11 + 2x-3 + 5x-2 = 180

Combine like terms

7x +2x+5x -11-3-2 =180

14x-16=180

Add 16 to each side

14x-16+16 =180+16

14x = 196

Divide each side by 14

14x/14 =196/14

x =14

<A =  7x -11 = 7*14 -11 = 98-11 = 87

<B = 2x-3 = 2*14 -3 = 28-3 = 25

<C = 5x -2 = 5*14 -2 = 70-2 = 68
