You purchase a $220 Arline ticket. You have a discount code to receive 10% off. There is a 10.5% service charge added to the tot

antoniya [11.8K]

When you see % next to a number, you multiply it by .01.
10 becomes .1
10.5 becomes .105

220*.1=22, so this is the 10% off
220*.105=23.1, so this is the 10.5% service charge.

220-22+23.1=$221.10 for the ticket.

Which expression is equivalent to <img src="https://tex.z-dn.net/?f=%5Csqrt128x%5E%7B8%7D%20y%5E%7B3%7D%20z%5E%7B9%7D" id="TexFo

Answer:

$(C)8x^4z^4\sqrt{2yz}$

Step-by-step explanation:

We want to determine an expression equivalent to: $\sqrt{128x^8y^3z^9}$

$\sqrt{ab} =\sqrt{a}*\sqrt{b}$

Therefore:

$\sqrt{128x^8y^3z^9}=\sqrt{128}*\sqrt{x^8}*\sqrt{y^3}*\sqrt{z^9}$

$=\sqrt{64*2}*\sqrt{x^{4*2}}*\sqrt{y^{2+1}}*\sqrt{z^{8+1}}\\=8\sqrt{2}*\sqrt{x^{4*2}}*\sqrt{y^2*y}*\sqrt{z^{8}*z}}$

$=8\sqrt{2}*x^4*y \sqrt{y}*z^4\sqrt{z}\\=8*x^4*z^4*\sqrt{2}*\sqrt{y}*\sqrt{z}\\=8x^4z^4\sqrt{2yz}$
