How many ounces of a 17 % alcohol solution must be mixed with 4 ounces of a 20 % alcohol solution to make a 19 % alcohol sol

andre [41]

Answer:

4 ounces

Step-by-step explanation:

Let the required amount is x.

<u>Alcohol content is same at the end:</u>

x*0.17 + 4*0.2 = (x + 4)*0.19
0.17x + 0.8 = 0.19x + 0.72
0.19x - 0.17x = 0.8 - 0.72
0.02x = 0.08
x = 0.08/0.02
x = 4

PLEASE HELP ME OUT!!

Zielflug [23.3K]

Answer:

(d) 1/√(s³)

Step-by-step explanation:

The expression can be simplified by making use of the rules of exponents.

<h3>Rules of exponents</h3>

The relevant rules are ...

$a^b\cdot a^c=a^{b+c}\\\\(a^b)^c=a^{bc}\\\\\left(\dfrac{a}{b}\right)^c=\dfrac{a^c}{b^c}\\\\a^{b/c}=\sqrt[c]{a^b}$

<h3>Application</h3>

The given expression can be simplified by applying these rules.

$\left(\dfrac{1}{s^{-1}\cdot s^8}\right)^{3/14}=\dfrac{1}{(s^{-1+8})^{3/14}}=\dfrac{1}{s^{7\cdot3/14}}=\dfrac{1}{s^{3/2}}=\boxed{\dfrac{1}{\sqrt{s^3}}}$
