(16x^1/6y^-2)^3/2 / (x^-1/6y^6)^3/2

=(4^2)^3/2 (x^1/6)^3/2 (y^-2)^3/2 / (x^-1/6)^3/2(y^6)^3/2
= 4^3 x^1/4 y^-3 / x^-1/4 y ^9
= 64 x^(1/4 +1/4) y^(-3-9)
= 64 x^1/2 y^-12
= 64 x^1/2 / y^12

answer is D.64 x^1/2 / y^12

If i have a pay rate of $21.00 and marked up 78.7% and made a 10% profit. how did i get $41.28?

Virty [35]

Step-by-step explanation:

Since we have given that

Amount of pay rate =$21

If she marked up by 78.7% , so it becomes

$78.7\%\text{ of}\$21\\\\=\frac{78.7}{100}\times \$21\\\\=\$16.527$

So, our amount for pay rate becomes

$21+16.527\\\\=\$37.527$

Now, he said he made a profit of 10%,so it becomes

$10\%\text{ of }37.527\\\\=\frac{10}{100}\times 32.527\\\\=\$3.7527$

So, our new pay rate becomes

$37.527+3.7527\\\\=\$41.2797$

This is the step through which we can get $41.28.
