256 being rounded would become 260 and 321 would become 320 so adding up the estimates the would be 580 (real answer is 577)
The answer is C because the x axis is 2 and the y axis is -2 so the answer is (2,-2).
Answer:
(C) 2√15
Step-by-step explanation:
Recognize that all the triangles are right triangles, so are similar to each other. In these similar triangles, the ratio of the short side to the long side is the same for all.
... CB/CA = CT/CB
... CB² = CA·CT = 10·6 = 60 . . . . . . . . . . multiply by CA·CB; substitute values
... CB = √60 = 2√15 . . . . . . . take the square root; simplify

<em>Comment on this solution</em>
The altitude to the hypotenuse of a right triangle (CB in this case) divides the hypotenuse into lengths such that the altitude is their geometric mean. That is ...
... CB = √(AC·CT) . . . . as above
This is true for any right triangle — another fact of geometry to put in your list of geometry facts.
First we have to find how much water leaked
5galllons-3 gallons=2 galllos of water leaked
Now we know

Finally we can simplify it

- its the answer
