Answer:

6 hours

Step-by-step explanation:

Cost = fee + charge per hour * number of hours

22 = 10 +2h

Subtract 10 from each side

22-10 = 10+2h-10

12 = 2h

Divide

12/2 = 2h/2

6 = h

Answer:

She kayaked for 6 hours.

Step-by-step explanation:

If $10 is the initial fee, subtract $22 - $10 = $12.

If it charges $2 per hour, divide $12 by $2 which equals 6 hours.

Rewrite the rational exponent as a radical by extending the properties of integer exponents. 2 to the 3 over 4 power, all over 2
Zepler [3.9K]
We are asked in this problem to determine the simplified expression of the statement given. The rules that apply in exponential functions is that when an exponential term is raised to the power of an integer, the simplified term has a degree that is equal to the product of the integers involved. The operations involved should be applicable to terms with the same base number only.  In this problem, we thus write:

2^3/4 / 2^1/2 = 2^3/4 * 2^-1/2 = = 2^(3/4 - 1/2) = 2^ 1/4. hence the answer is 2^0.25 or simply equal to 1.1892 determined using a calculator.
