The diameter of the moon is 2160 miles. a model has a scale of 1 in : 150 mi. what is the diameter of the model?

Let x be the diameter of the model.

x in : 2160 mi = 1 in : 150 mi

x = 2160 x (1/150)
   = 2160/150 
   = 14.4 in 

Therefore, the diameter of the model is 14.4 inches. 

Your cleary not see the answer is 25

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
