streamline bicycles produce two kinds of bikes, mountain bikes and road bikes. It takes 4 hours to build a mountain bike and 3 hours to build a road bike. The company has 21 employees, each with a 40 hour work week. Due to demand, they must produce at least 250 total bikes each week. If they profit $75 on each mountain bike and $60 on each road bike, how many of each type should they produce in a week to maximize their profit?

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.  

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
