a passenger car will go 546 miles on 19.5 gallons of gasoline in city driving. what is the rate in miles per gallon?

answer: howdy

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
