Perform the operation(s) and write the answer in simplest form.
ss7ja [257]
First do 12-5, which equals 7.  Next, subtract 1/10 from 2/5.  2/5 is the same as 4/10 if you multiply both the numerator and denominator by 2.  4/10-1/10=3/10. Now add 7 and 3/10.  You will get 7 3/10 as the answer, which is letter C.)

The 6% state income tax on a 42'000 salery​
Romashka [77]

Answer:

well, simply, it would be $2520.

in reality, an income tax does not work that simply. income taxes are figured using brackets, where (just making up numbers) the first $15000 might be taxed at 2%, earnings between $15,001 to $30,000 are taxed at 4%, and so on.

Thus, without knowing the tax tables to know the different rates and brackets, it's impossible to give an answer.

But in straight math terms, 6% of $42,000 is $2520

42000×.06= 2520

pentagon [3]

Trigonometric functions are not only used in cases of an object that has a cyclical behavior.

<h3>What is a trigonometric function?</h3>

It should be noted that trigonometric functions are real functions that relate the angle of a right angled triangle to the ratios of the two side lengths.

Trigonometric functions are not only used in cases of an object that has a cyclical behavior. It can be used to obtain unknown <em>angles</em> in geometric figures.

It can also be used to model the fluctuations in temperature data for a particular year.

The movement of a yo-yo can be modeled by a sinusoidal curve since it exhibits a periodic behavior.

Scrat [10]

Principal clements needs to buy 10 packages

<em><u>Solution:</u></em>

Given that, Principal clements wants to buy a pencil for each of the 57 fourth graders in her school

The pencils come in packages of 6

Therefore,

Total number of students = 57

<em><u>Thus, divide 57 by 6 to get the number of packages clements need to buy</u></em>

\text{Number of packages } = \frac{\text{total number of students }}{6}<em><u></u></em>

<em><u>Substituting the given values we get,</u></em>

\text{Number of packages } = \frac{57}{6} \\\\\text{Number of packages }= 9.5 \approx 10

Thus principal clements needs to buy 10 packages
