Answer:  AD = 108

               BD = 105

             ADB = 213

             ABC = 182

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

If no radius is given, assume it is length 1.

Then, the length of the arc is equal to the central angle.

Reminder that a circle is 360°

\bold{\underline{\stackrel\frown{AD}:}}

The central angle = 108°, so the arc length = 108

\bold{\underline{\stackrel\frown{BD}:}}

BD = BC + CD

     = 35° + 70°

     = 105°

The central angle = 105°, so the arc length = 105

\bold{\underline{\stackrel\frown{ADB}:}}

ADB = AD + CD + BC

     = 108° + 70° + 35°

     = 213°

The central angle = 213°, so the arc length = 213

\bold{\underline{\stackrel\frown{ABC}:}}

First, find the angle of AB.

AB = 360° - ADB  

     = 360° - 213°      

     = 147°

ABC = AB + BC

     = 147° + 35°

     = 182°

The central angle = 182°, so the arc length = 182

You are making a walkway around part of a swimming pool. The dimensions of the swimming pool are 18 and 25, while the dimensions
vredina [299]

Answer:

A = 4x^2 + 86x + 450

Step-by-step explanation:

Given

Walkway = x

Length = 18

Width = 25

Required:

The area of the swimming pool

Assume the walkway will be on the 4 sides of the swimming pool.

The total length (L) of the swimming pool will be:

L = 18 + x + x

L = 18 + 2x

The total width (W) will be:

W = 25 + x + x

W = 25 + 2x

The area (A) is:

A = L * W

A = (18 + 2x) * (25 + 2x)

Expand bracket

A = 18 * 25 + 18 * 2x + 25 * 2x + 2x * 2x

A = 450 + 36x + 50x + 4x^2

A = 450 + 86x + 4x^2

Reorder

A = 4x^2 + 86x + 450

Clarice Sloan is a shift supervisor for Ace

The net pay is the amount left after taxes and deductions have been removed from the gross pay.

Her monthly gross pay is: $4111.93

The deductions are:

\mathbf{FIT = \$102}

\mathbf{SIT = 3.2\%}

\mathbf{CIT = 1.8\%}

Let her gross pay be x.

So, we have:

\mathbf{Net = x - FIT - x \times SIT - x \times CIT}

So, we have:

\mathbf{3804.33 = x - 102 - x \times 3.2\%- x \times 1.8\%}

Express percentage as decimals

\mathbf{3804.33 = x - 102 - x \times 0.032- x \times 0.018}

\mathbf{3804.33 = x - 102 - 0.032x -  0.018x}

Add 102 to both sides

\mathbf{3906.33 = x - 0.032x -  0.018x}

\mathbf{3906.33 = 0.95x}

Divide both sides by 0.95

\mathbf{4111.93 = x}

Rewrite as:

\mathbf{x = 4111.93 }

Hence, her monthly gross pay is: $4111.93
