Answer: (16) B       (17) C       (18) A       (19) C        (20) B

<u>Step-by-step explanation:</u>

16.\quad \bigg|\dfrac{m}{6}\bigg|>3\\\\\\.\quad \quad \dfrac{m}{6}>3\qquad or \qquad \dfrac{m}{6}

        m > 18      or        m < -18

17.  -5 | 2b - 8| > -90

          | 2b - 8| < 18

     2b - 8 < 18        or     2b - 8 > -18

           2b < 26                    2b > -10

             b <  13       or            b > -5

18.\quad \dfrac{|-2+6b|}{6}

        | -2 + 6b| < 30

         -2 + 6b < 30      or     -2 + 6b > -30

                6b < 32                      6b > -28

                 b < 32/6                       b > -28/6

                 b < 16/3      or              b > -14/3

19)    |9 - 2x| - 4 ≤ -1

            |9 - 2x|  ≤ 3

               9 - 2x ≤ 3     or      9 - 2x ≥ -3

                   -2x ≤ -6                 -2x ≥ -12

                      x ≥  3     or             x ≤  6

20)   | 5 - 6x | - 2 < 53

            | 5 - 6x |  < 55

                5 - 6x < 55     or    5 - 6x > -55

                    -6x < 50                 -6x > -60

                       x > -50/6                x < 10

                      x > -25/3

Which inequality represents the sentence? The difference of seven and two tenths and a number is more than twenty nine. 7. 2 - n
Slav-nsk [51]

The inequality which represent, the difference of seven and two tenths and a number is more than twenty-nine, is

7.2-n > 29

<h3>What is the inequality equation?</h3>

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

Inequality is represented with the greater then(<), less then(>) or with the other inequity signs like less than equal to \leq or greater than equal to \geq.

Tenth is written as the fractional part of the number 10. The value of one tenth is equal to 1/10 or 0.1.

The sentence given for the inequality expression is, that the differences of seven and two tenths, and a number is more than twenty-nine.

The number seven and two tenths can be written as,

7\dfrac{2}{10}

Suppose the unknown number is n.  Now, the differences of seven and two tenths, and this number (<em>n</em>) is more than twenty-nine.  The more than word means, the greater than sign for equation. Thus, it can be expressed as,

7\dfrac{2}{10}-n > 29\\\dfrac{72}{10}-n > 29\\7.2-n > 29

Hence, the inequality which represent, the difference of seven and two tenths and a number is more than twenty-nine, is

7.2-n > 29

If x=12 in, y=16, and z=20 in, what is the surface area of the geometric shape formed by this net?
maria [59]

Given:

x = 12 in, y = 16 in and z = 20 in

To find:

The surface area of the geometric shape.

Solution:

Area of top rectangle = z × z

                                    = 20 × 20

Area of top rectangle = 400 in²

Area of middle rectangle = z × y

                                          = 20 × 16

Area of middle rectangle = 320 in²

Area of bottom rectangle = z × x

                                          = 20 × 12

Area of bottom rectangle = 240 in²

Area of left triangle = \frac{1}{2}yx

                                $=\frac{1}{2}\times16\times12

Area of left triangle = 96 in²

Area of right triangle = \frac{1}{2}yx

                                $=\frac{1}{2}\times16\times12

Area of right triangle = 96 in²

Surface area = 400 + 320 + 240 + 96 + 96

                     = 1152

The surface area of the geometric shape is 1152 in².
