17 Mark for Review A raised garden is in the shape of a right rectangular prism. Its base has a width of 3 feet and a length of 27 feet, and it will be filled 24 inches high with topsoil. The total cost of the topsoil needed to fill the garden to this height is 234 dollars. What is the unit cost, in dollars per cubic yard, for the topsoil? \( (1 \) yard \( =3 \) feet; 1 foot \( =12 \) inches)

18. \( \frac{9!}{\mathrm{P}_{8}+\mathrm{P}_{7}} \)

Rewrite the fraction in the sentence below as a percentage. In a certain class, \( \frac{21}{25} \) of the students got problem 5 wrong on Friday's math test. Percent notation: \( \square \% \)

\( \left(\log _{9} 4\right) \cdot\left(\log _{4} 5\right) \cdot\left(\log _{5} 6\right) \cdot\left(\log _{6} 7\right) \cdot\left(\log _{5} 8\right) \cdot\left(\log _{5} 9\right)= \) (A) 4

Express \( x^{\frac{3}{4}} \) in terms of a radical expression.

Simplify: \( \frac{(6.25)^{\frac{1}{2}} \times(0.0144)^{\frac{1}{2}}+1}{(0.027)^{\frac{1}{3}} \times(81)^{\frac{1}{4}}} \)
