Con quale unità di misura esprimeresti il volume di una stanza? Indica la risposta corretta. (A) dam B) \( \mathrm{m}^{3} \) (C) \( \mathrm{dm}^{3} \)

Diego is collecting dimes and nickels in a jar. He has collected \( \$ 22.25 \) so \( * 25 \) points far. The relationship between the numbers of dimes and nickels, and the amount of money in dollars is represented by the equation . \( 10 \mathrm{~d}+.05 \mathrm{n}= \) 22.25 (d, n\( ) \) \( (0,445) \) \( (0.50,435) \) \( (1183,209) \)

Question 3 (5 points) If John ran a 5-kilometer marathon, how long was that in meters?

1. \( \frac{x^{2}}{8}+\frac{y^{2}}{4}=1 \) 2. \( \frac{x^{2}}{16}+\frac{(y-2)^{2}}{25}=1 \) 3. \( (x-1)^{2}+(2 y-2)^{2}=4 \)

2.) \( 8-(-9)= \)

\begin{tabular}{l} a) \( 5^{x}=125 \) \\ bl \( 10^{x}=10000 \) \\ c) \( 9^{x}=243 \) \\ d) \( \left(\frac{1}{2}\right)^{x}=\frac{1}{32} \) \\ \hline e) \( \left(\frac{1}{4}\right)^{x}=0,25 \) \\ \hline fl \( 4^{x}=\frac{1}{64} \) \\ \hline\end{tabular}
