Water flows back and forth between a small and large tank. When water is moving into a tank the flow rate is positive, and when water is moving from a tank the flow rate is negative. Each tank begins with 250 gallons of water. The flow rate for the large tank is recorded as –6 gallons per minute. After a period of 25 minutes, which integer represents the amount of water left in the large tank? A. -400 B. -100 C. 100 D. 400 HELP PLEASE

C. 100

Step-by-step explanation:

If  the large tank is flowing at a constant rate of  -6 per minute then we have to know that the water is moving from the tank. So is asking how many water will be left in the tank after 25 minutes.

You could use the equation

y = -6x  + 250  where y is the amount of water left in the tank and x is the number of minutes.

So if x is 25 then plot it in and solve for y.

y = -6(25) +250

y = -150 +250

y= 100  

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.  

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
