Answer: 216 in

Step-by-step explanation: I used the formula A=1/2(b1+b1)h and I filled it in by doing A=1/2(6+12)6 and then I divided the height by 1/2 and i multiplied 72 by 3 which is 216 in.

A wildlife service wanted to estimate the number of alligators in a river so they tagged 90 alligators and released them back in
lilavasa [31]
You can solve this with a proportion. If you know that 23 tagged alligators were in a 200 alligator sample, there are 90 tagged alligators in the entire river. Written otherwise:

23/200 = 90/x    

and solve for x:

x = 782.608...

So the "best estimate" would be around 783 alligators. Hope that helps! If you liked this answer please rate it as brainliest!! thank you!!!
