Ms. Benoit is a self-employed architect who earns $300,000 annual taxable income. For the past several years, her tax rate on th
blagie [28]

Answer:

a

   Y  = \$ 30000

b

  Y  = \$ 11250

c

  X  = \$  36250

Step-by-step explanation:

From the question we are told that

   The annual taxable income is A = \$ 300,000

   The tax rate for next year is  r =  0.25

   The  present tax rate is  R =  0.35

 

Generally the present amount of tax collected from Ms Benoit is  

         K =  A   * R

        K =  300000  * 0.35

=>       K =   \$105000

Generally the  amount of tax collected from Ms Benoit nest year  is

          B =  A   * r

        B =  300000  * 0.25

=>       B =   \$75000        

The  reduction in the tax amount is mathematically represented as

       Y  =  K  - B

=>     Y  =  105000  - 75000

=>    Y  = \$ 30000

Generally the tax amount of next year when the income is  $375,000 is mathematically represented as

    M  =  375 000   *   r

=>    M  =  375 000   *   0.25

=>     M  =  \$ 93 750

The  reduction in the tax amount is mathematically represented as when  the income for next year  is  $375,000

             Z  =  K  - M

=>     Z  =  105000  -93 750

=>    Z  = \$ 11250

Generally the tax amount of next year when the income is  $275,000 is mathematically represented as

    U  =  275,000   *   r

=>    U  =  275 000*   0.25

=>     M  =  \$ 68 750

The  reduction in the tax amount is mathematically represented as when  the income for next year  is  $275,000

             X  =  K  - M

=>     X  =  105000  -68 750

=>    X  = \$  36250

If tan⁡ x= root of 3, and 180°
BartSMP [9]

Answer:

\dfrac{1}{2}

Step-by-step explanation:

If 180^{\circ} then angle x is in the III quadrant.

Since \tan x=\sqrt{3}, then x=240^{\circ}\ [180^{\circ}+60^{\circ}] (we get angle in the III quadrant)

Consider \sin (x-210^{\circ}).

If x=240^{\circ}, then

\sin (240^{\circ}-210^{\circ})\\ \\=\sin 30^{\circ}\\ \\=\dfrac{1}{2}
