Answer:
[tex]12\dfrac{1}{8}\ feet[/tex]
Step-by-step explanation:
Sonya drops a marble while standing on a deck [tex]7 \dfrac{7}{8}[/tex] feet above the ground.
The marble falls [tex]4 \dfrac{1}{4}[/tex] feet from Sonya's hand to the deck, and then rolls and falls to the ground.
So, the ball falls [tex]4 \dfrac{1}{4}[/tex] feet from Sonya's hand to the deck and [tex]7 \dfrac{7}{8}[/tex] from the deck to the ground, in total
[tex]4\dfrac{1}{4}+7\dfrac{7}{8}=4\dfrac{2}{8}+7\dfrac{7}{8}=(4+7)+\dfrac{2+7}{8}=11+\dfrac{9}{8}=11+1\dfrac{1}{8}=12\dfrac{1}{8}\ feet[/tex]
