Taylor saw an American alligator at a zoo that measured Ask Your Teacher feet long. The record length of an American alligator i
lianna [129]

Answer:

The record alligator is 6\frac{1}{4} feet longer than the alligator Taylor saw.

Step-by-step explanation:

Taylor saw an American alligator at a zoo that measured 12\frac{11}{12} feet long. The record  length of an American alligator is 19\frac{1}{6} feet long. How much longer is the record  alligator than the alligator Taylor saw?

For this first convert the mixed fraction into an improper fraction.

12\frac{11}{12}=\frac{155}{12}

19\frac{1}{6}=\frac{115}{6}

Now subtract \frac{155}{12} from \frac{115}{6}.

\frac{115}{6}-\frac{155}{12}=\frac{75}{12}=6\frac{1}{4}

Hence, the record alligator is 6\frac{1}{4} feet longer than the alligator Taylor saw.

Find the velocity first, the "slope".

m=(y2-y1)/(x2-x1)

m=(95.5-53)/(4-2)

m=21.25  ?  Your equations are wrong, I'll double check with another set of points...

m=(350.5-308)/(16-14)

m=21.25  LOL, yep none of your lines has the correct slope.

Anyway...

y=21.25x+b, using any point we can solve for the y-intercept, or "b", (2, 53)

53=21.25(2)+b

53=42.5+b

10.5=b so the distance to the lighthouse as a function of time is:

y=21.25x+10.5

So essentially, you should fire your teacher or burn that book you are using :)
