The sales tax is $3.2 and total cost is $ 43.2

Solution:

Given, An item sells for 40$  

And sales tax on the item is 8 %  

We have to find what is the sales tax and total cost

Now, we know that, sales tax = 8% of selling price  

\begin{array}{l}{\text { Sales tax }=\frac{8}{100} \times \text { selling price }} \\\\ {\text { Sales tax }=\frac{8}{100} \times 40} \\\\ {\text { Sales tax }= 3.2}\end{array}

Now, sales tax = $ 3.2, then,

<em>Total final cost = selling price + sales tax </em>

Total cost = 40 + 3.2

Total cost = $ 43.2

Hence, sales tax and total cost are $3.2 and $43.2 respectively.

(k-2)(k-6)=k^2-2k-6k+12=k^2-8k+12

So in order to get all the fractions to have a common denominator, we need to multiply \dfrac k{k-2} by \dfrac{k-6}{k-6}, and \dfrac1{k-6} by \dfrac{k-2}{k-2}:

\dfrac k{k-2}\cdot\dfrac{k-6}{k-6}=\dfrac{k(k-6)}{(k-2)(k-6)}=\dfrac{k^2-6k}{k^2-8k+12}

\dfrac1{k-6}\cdot\dfrac{k-2}{k-2}=\dfrac{k-2}{(k-2)(k-6)}=\dfrac{k-2}{k^2-8k+12}

Now,

\dfrac4{k^2-8k+12}=\dfrac{(k^2-6k)+(k-2)}{k^2-8k+12}

As long as k\neq2 and k\neq6 (which we can't have because otherwise k^2-8k+12=0), we can cancel k^2-8k+12 in the denominators on both sides:

4=(k^2-6k)+(k-2)

4=k^2-5k-2

0=k^2-5k-6

We can factorize the right side:

0=(k-6)(k+1)

which tells us that k=6 and k=-1 are solutions.

Help quickly pls area of a triangle: sine formula
AysviL [449]

Answer:

If you were to use the sine formula you would have to use the cosine formula to get one of the opposite sides and then use the sine formula.

For the area why not use 1/2 * 20 to get the base.

Then the height would be 24 * sin 63 = 21.38

That would give an area of 213.8
