Mathematics

Answer:

99.37

Step-by-step explanation:

Brief Math lesson:

If you, for example, pay 10% of your income of $100 to charity and 5% of it goes to taxes,

The amount that goes to charity can be found by using:

10% * 100 = 0.1 * 100 = 10

And the amount for taxes is

5% * 100 = 0.05 * 100 = 5

So the total is 15 dollars. And then, subtract that from your salary, so you would earn 85 dollars

We can also just find it by finding how much of a total percentage is being taken and subtract that by 100. (because you would keep the rest of the money)

(100% - (10% + 5%)) * 100 = 85% * 100 = 85

Now, let's apply this information.

First, figure out how much you need to pay in taxes, social security, etc.

15% + 6.44% + 6.2% + 1.45% = 29.09% of your money is given away. So, you would keep 100% - 29.09%, which is 70.91% kept

10.01 dollars an hour at 14 hours is 10.01*14 = 140.14 dollars

Now, multiply the percent of salary you keep by your salary.

140.14 * 70.91% = 140.14 * 0.7091 = 99.373274

This is, rounded,

99.37

Given sin theta=5/13 and cos theta=12/13, which of the following can be proven using a Pythagorean identity?
ZanzabumX [31]

Answer:

4th option

Step-by-step explanation:

given

sinΘ = \frac{5}{13} and cosΘ = \frac{12}{13} , then

( \frac{5}{13} )² + ( \frac{12}{13} )²

= \frac{25}{169} + \frac{144}{169}

= \frac{25+144}{169}

= \frac{169}{169}

= 1

showing sin²Θ + cos²Θ = 1

Can someone PLEASE explain how to simplify square roots with variables and eexponents in them?? I'd also be thankful if you expl
Verizon [17]
X^a/b is  \sqrt[b]{x^a} . The way I memorise that is x^1/3 is the cubic root of x. Do you get it? In that case, x is raised to a power of 1 and the cubic root is practically has a power of 3.
In your example, 

\sqrt[ \frac{3}{2} ]{16 x^4} is practically square rooting each term then cubing them individually. Remember when square-rooting any index you halve it. I'll elaborate:

\sqrt{x^4} = x^{2}
\sqrt{16} = 4
Then cube each,
4^3 = 64 
and ( x^{2} )^3 = x^{6}

As for the 2nd part: you must use the rules of indices.
x^{a}  *  x^{b} =  x^{a+b}
So breaking the question up:

3 * 3 = 9
x^{ \frac{1}{2} } stays as is since the 2nd term does not contain x
now: 
y^{ \frac{4}{3} }  * y^{1} =  y^{ \frac{4}{3} + 1 }  =  y^{ \frac{4}{3} +  \frac{3}{3} }  =   y^{ \frac{7}{3} }
This makes your final answer look like this:
9 x^{ \frac{1}{2} }  y^{ \frac{7}{3} }

I hope that helped and good luck in your test!
