An albatross is a large bird that can fly 400 kilometers in 8 hours at a constant speed. Using  for distance in kilometers and  for number of hours, an equation that represents this situation is . What are two constants of proportionality for the relationship between distance in kilometers and number of hours? What is the relationship between these two values?

Write another equation that relates  and  in this context.

Explain how you can find the missing fraction in 3 4/5 / (blank) 2 5/7. then find the missing fraction.

Which of the following would be a correct step in proving that triangle abc is congruent to triangle cda? a. use a protractor to measure the angles and show that all the corresponding angles are equal in measure. this will allow you to prove congruence by aaa. b. show that segment ab is parallel to segment cd and segment ad is parallel to segment cb. this will allow you to prove congruency by asa. c. show that is segment ab is perpendicular to segment ad. this will allow you to prove congruence by sas. d. none of the above.
