They travelled 5115 km total. Their average speed was 93 km/h. They drove for 5 hours per day, 4 days per week. How many days did their trip last altogether?

Then what is line FC again? For a hint, read the yellow words at the bottom of the slide, but always try some of your own thoughts first! In the figure on the right, AC || EG.

The jeweler offers her a deal where she only pays the same percentage of the price that the pure onyx represents of the stone. If the ring costs $1500, how much will Coralie pay before taxes? Hint: What is the area of the white spot? What is the area of the whole stone? What % of the whole stone is pure onyx (black)? A -shaped black onyx stone is made into a ring. The stone JUST fits inside a pink, rectangular box that measures 4cm x 6cm. 4cm 6cm $ 5 Always simplify your final answers when possible 4 2 10 12 5 6 10 7 + - - 3 1 2 4 3 2 1 6 5 = = = Consider the bag of marbles on the right for the following probability questions.
