The natural history museum has a 1:75 scale model of an apatosaurus dinosaur. the length of the model is 30 centimeters. find the actual length x (in meters) of an apatosaurus.
For this case what we should do is write the expression of the ratios. We have then: (75/1) = (x / 30) Clearing x we have: x = 30 * (75/1) x = 2250 cm Then, you must take into account the following conversion: 1m = 100cm We have then: x = 2250 * (1/100) = 22.50m Answer: the current length x (in meters) of an apatosaurus is: x = 22.50m
