Select the correct answer. The population of deer in a forest is currently 800 individuals. Scientists predict that this population will grow at a rate of 20 percent per year. Based on this prediction, about how many years will it take for the population to double in size? Use the equation [tex]$P=P_0(1+r)^{ t }$[/tex], in which [tex]$P_0$[/tex] represents the initial population size, [tex]$r$[/tex] represents the growth rate, [tex]$t$[/tex] represents the number of years, and [tex]$P$[/tex] represents the final population size. A. 3.8 years B. 5.0 years C. 0.3 year D. 1.8 years
Answer (3)
Here you have to use proportionality, 1 feet is 12 inches so 40 feets is 480 inches Then the real locomotive is 480/16=30 times wider then the model And then a window on the real locomotive is 30 times wider then the model..
30 times wider than the model ;
A window on the real locomotive is 30 times wider than a window on the model. This is determined by comparing their lengths, which are in the same proportion. Therefore, if the proportions are consistent, the window sizes also follow this ratio.
