Sally's family is going to visit her grandparents for the holidays. They live 585 miles away. Sally's parents plan to drive for 5.5 hours on the first day, then stop at a hotel for the night and complete the rest of the trip on the second day. They plan to maintain an average speed of 60 miles per hour. Which equation can Sally use to find how many hours, \( h \), they can expect to drive on the second day? \( 5.5 h+60=585 \) \( 60 h+5.5=585 \) \( 60(h+5.5)=585 \) How many hours can Sally's family expect to drive on the second day? Write your answer as a whole number or a decimal. \( \square \) hours

Jika koordinat titik-titik sudut persegi panjang \( A B C D \) adalah \( A(2,2), B(7,2) \), \( C(7,5) \), dan \( D(a, b) \) dirotasi sejauh \( 180^{\circ} \) maka bayangan titik \( D \) adalah ... . Select one: \( \begin{array}{ll}\text { a. }(-2,-5) \\ \text { b. }(2,5) \\ \text { c. }(5,2) \\ \text { d. }(5,-2)\end{array} \)

The vertices of \( \triangle A B C \) are \( A(5,-3), B(-1,-5) \), and \( C(4,3) \). For the translation below, give the vertices of \( \triangle A^{\prime} B^{\prime} C^{\prime} \). \( T_{\langle-2,4\rangle}(\triangle A B C) \)

Use the fact that for an \( n \times n \) matrix \( A,|c A|=c^{n}|A| \), to evaluate \( \left|\begin{array}{ccc}20 & 10 & 20 \\ 10 & 15 & 20 \\ 10 & 15 & 15\end{array}\right| \).

The probability is \( \square \). (Type an integer or a fraction. Simplify your answer.)

If a molecule happens to move further in the gel, what does that likely say about its size? What about its charge and why?
