242 cm because 418/ 3.8 = 110, 110 x 2.2 = 242 cm
The Formula Of Volume Is :
V = L*W*H. So, Lets Plug In The Known Values.
V = 16*16*16.
16*16 = 256.
256 * 16 = 4096 yr^3. This Is The Volume. Any Further Questions?
1/2 × 5 2/3 × 3 = 5
the 2's cancel giving you 5 × 1/3 × 3
then the 3's cancel giving you 5 × 1
and 5 × 1 is 5.
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.
X=11, set 10x+5x+15=180
15x+15=180, subtract 15 from 180= 165, then divide 165 by 15
