What is the sales tax on a jacket priced at $725 if the sales tax rate is 7%

Fiesta28 [93]

<span>Sales tax on a jacket with the price of 725 dollars.
the sales tax rate is 7%
=> Convert 7% into decimals
=> 7% / 100 = 0.07
Now, multiply the 0.07 in 725 dollars
=> 50.75
thus the total tax rate of the jacket price is 50.75
Now, let us calculate the total amount that you will be paying
=> 725 + 50.75
=> 775.75 = the total amount to be paid.</span>

Hasil dari 64^5/6 + 27^2/3 - 81^3/4 adalah<br>tolong bantuannya kakak kakak<br>

Answer:

14

Step-by-step explanation:

Given the indicinal expression 64^5/6 + 27^2/3 - 81^3/4

According to indices;

$a^{m/n} = (\sqrt[n]{a}) ^m$

Applying this to the question

$64^{5/6} \\= (\sqrt[6]{64}) ^5\\= 2^5= 32$

Similarly

$27^{2/3}\\= (\sqrt[3]{27}) ^2\\= 3^2\\= 9\\$

Also;

$81^{3/4}\\= (\sqrt[4]{81}) ^3\\= 3^3\\= 27$

Substitute inti the original equation

64^5/6 + 27^2/3 - 81^3/4

= 32 + 9- 27

= 41 - 27

= 14

Hence the required answer is 14
