Answer:

12 ounces

Step-by-step explanation:

0.30 x + 0.35 (18) = 0.33 (x + 18)

0.30 x + 6.3 = 0.33 x + 5.94

0.36 = 0.03 x

x = 12

Rewrite the expression with rational exponents as a radical expression by extending the properties of integer exponents.
ra1l [238]

The expression will be written as \rm \sqrt[8]{2^5}., the correct option is A.

<h3>What are Exponents?</h3>

Exponents are the base raised to a power, It is written in the superscript of a number.

The expression given in the statement can be written as

\rm \dfrac{ 2^{7/8}}{2^{1/4}}

By the Exponent rule,

\rm \dfrac{a^m}{a^n} = a^{m-n}

So the expression can be written as

<h3>=\rm { 2^{7/8-1/4}</h3>

=\rm 2^{5/8}

=\rm \sqrt[8]{2^5}

Therefore, in radical form, the expression will be written as \rm \sqrt[8]{2^5}., the correct option is A.

The complete question is

Rewrite the rational exponent as a radical by extending the properties of integer exponents.

2 to the 7 over 8 power, all over 2 to the 1 over 4 power

the eighth root of 2 to the fifth power

the fifth root of 2 to the eighth power

If you spin the spinner below twice, what is P(vowel, then Q)? A. 1/10 B. 1/9 C. 2/9 D. 1/12 Answer correctly and I will give br
bagirrra123 [75]

Answer:

The probability of spinning a vowel, then Q, is 1/12

Step-by-step explanation:

Find the probability of each event occurring. There are three vowels out of 6 letters and 1 Q, so the chances of spinning a vowel is 3/6 or 1/2 and the chances of spinning a Q is 1/6. Multiply the probabilities of the two events occurring to find the probability of a compound event. 1/2*1/6 = 1/12. Hope this helps!
