The deepest point of lake titicaca in south america is -922feet relative to its surface. the deepest point is 11,542 feet above sea level. what is the elevation of the surface of the lake

There are two observations drawn from the given question,

Deepest point of lake Titicaca to its surface is -922 feet relative to its surface.Deepest point of the lake is 11542 feet above the sea level.

All the distances above the sea level are positive and below the sea level are negative.

Since, deepest level of the lake is above the sea level and surface is above the deepest point.

Therefore, surface will also be above the sea level.

Elevation of the surface of the lake = Distance between the sea level and the deepest point of the lake + Distance between the surface and the deepest point of the lake

= 11542 + 922

= 12464 feet

Therefore, elevation of the surface of the lake is 12464 feet above the sea level.

Acetic acid  /əˈsiːtɪk/, systematically named  ethanoic acid  /ˌɛθəˈnoʊɪk/, is a colourless liquid  organic compound  with the  chemical formula  ch3cooh (also written as ch3co2h or c2h4o2). when undiluted, it is sometimes called  glacial acetic acid.  vinegar  is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. acetic acid has a distinctive sour taste and pungent smell. in addition to household vinegar, it is mainly produced as a precursor to  polyvinyl acetate  and  cellulose acetate. it is classified as a  weak acid  since it only partially  dissociates  in solution, but concentrated acetic acid is corrosive and can attack the skin.acetic acidnamespreferred iupac nameacetic acidsystematic iupac nameethanoic acidother namesvinegar (when dilute); hydrogen acetate; methanecarboxylic acid[1][2]identifierscas number64-19-7  3d model (jsmol)interactive image3dmetb00009 reference506007chebichebi: 15366  chemblchembl539  chemspider171  drugbankdb03166  echa infocard100.000.528ec number200-580-7e numbere260  (preservatives)gmelin reference1380iuphar/bps1058keggd00010  meshacetic+acidpubchem  cid176rtecs numberaf1225000uniiq40q9n063p  un number2789inchiinchi=1s/c2h4o2/c1-2(3)4/h1h3,(h,3,4)  key:   qtbsbxvteameqo-uhfffaoysa-n  smilescc(o)=o
