Sharifah earned $61,000 last year. If the first $34,000 is taxed at 11% and income above that is taxed at 17%, how much does Sha
Marina CMI [18]

Using proportions, it is found that Sharifah owns $8,330 in taxes.

<h3>What is a proportion?</h3>
  • A proportion is a <u>fraction of total amount</u>, and the measures are related using a rule of three.
  • Hence, using proportions, a percentage x% of an amount a is given by: \frac{x}{100} \times a.

<h3>Taxes for the first $34,000:</h3>
  • Rate of 11%, hence:

T_1 = 0.11(34000) = 3740

<h3>Taxes for the amount above $34,000:</h3>
  • The amount taxed is $27,000, as 61000 - 34000 = 27000.
  • Rate of 17%, hence:

T_2 = 0.17(27000) = 4590

Then, the total amount is:

T = T_1 + T_2 = 3740 + 4590 = 8330

Sharifah owns $8,330 in taxes.

Answer:

The cubed root of four hundred and forty-eight ∛448 = 7.6517247310896

Step-by-step explanation: Step by step simplification process to get cube roots radical form and derivative:First we will find all factors under the cube root: 448 has the cube factor of 16.Let's check this width ∛16*7=∛448. As you can see the radicals are not in their simplest form.Now extract and take out the cube root ∛16 * ∛7. Cube of ∛16=4 which results into 4∛7All radicals are now simplified. The radicand no longer has any cube factors.

Answer:

a =  \sqrt{3}

Step-by-step explanation:

\frac{2 \sqrt{3} }{ \sin(90) }  =  \frac{a}{ \sin(30) }  \\  \frac{2 \sqrt{3} }{1}  =  \frac{a}{ \frac{1}{2} }  \\ a =  \frac{1}{2}  \times 2 \sqrt{3}  \\ a =  \sqrt{3}
