Answer:

The equation above represents the total time the play director spent preparing for a play.

Step-by-step explanation:

The time spent by the play director for preparing for a play is, 190 hours.

Of these 190 hours, the director spent varying amounts of time attending 35 rehearsals for the play.

Let the varying amounts of time be denoted by, <em>x</em>.

The director also spent 3/4th of an hour, i.e. 45 minutes, on other responsibilities related to the play.

The equation provided is:

Answer:

OPTION C

Step-by-step explanation:

We have the following rules:

$ \sqrt[a]{x} = x^{\frac{1}{a} $    and

$ x^a . x^b = x^{a + b} $

OPTION A: $ x \sqrt[7]{x} $

= $x . x^{\frac{1}{7} $

= $ x^{1 + \frac{1}{7} $

$ = x^{\frac{8}{7} $ $ \ne x^{\frac{9}{7} $

So, it can be eliminated.

OPTION B: $ \bigg ( \frac{1}{\sqrt[7]{x}} \bigg )^9 $

= $ \bigg ( \frac{1}{x^{\frac{1}{7}}} \bigg )^9 $

= $ \bigg ( x^ {\frac{-1}{7}} \bigg )^9 $

= $ x^{\frac{-9}{7}} $

So, this option is also eliminated.

OPTION C: $ x . \sqrt[7]{x} $

= $ x . x^{\frac{1}{7}} $

= $ x^{1 + \frac{1}{7}} $

= $ x^{\frac{9}{7}} $

So, OPTION C is the answer.

Logan earned $8 for each dog he walked last summer. This summer, he raised his fee to $9 per dog. Express the change in Logan’s
hammer [34]

Answer:

The fee increased 12.5%

Step-by-step explanation:

The new price is 9 and the old price is 8, so you can find the change by doing

9/8

which is 1.125

This means the new price is 12.5% higher than last year because you have to ignore the 1 in front and only look at the .125

Move the decimal place two to the right to get 12.5 and then add the % sign.
