The coarser fluviatile sediments are especially well defined in this area by granulometric analyses. Only during floods and owing to the systems of irrigation practiced are sediments supplied to the soils. Under normal conditions transport of sediment in the channel is directed largely towards the sea. An outline is liven of the most important means of sediment transport and deposition in the Nile-Valley. The size-distribution analyses and the heavy mineral analyses of seventeen surface samples have been studied. The coincidence of ore shoots and alteration body with certain structural elements of the Casapalca anticlinorium is discussed. The results of a systematical thin-slide study of the rock type under discussion are in favour of alteration. Various opinions about the origin have been brought forward. In the centre of the mine in the single zone of the most conspicuous parallel vein system a body of rock has been intersected that does not fit in the stratigraphical sequence. The Casapalca mining district in central Peru is a source of lead, zinc, silver and copper ores of the lepthothermal type. (c) The pet store will pay S3.49 for each fish.The central alteration body of the Casapalca mines, Peru What is the largest whole number of fish that she can keep in the aquarium? If there is any amount less than this, no matter how much less, the pet store will not accept Diane's fish. (b) The particular species Diane plans to raise requires at least 1.1 ft of water per fish. Conversion facts for length 1 foot (t) = 12 inches (in) 1 yard (yd) = 3 feet (11) 1 yard (yd) = 36 inches (in) Use the table of conversion facts, as needed. (a) Find the volume of water that the tank holds in cubic feet.
She finds the answer, but it is given in cubic feet. Diane looks up the amount of water needed for the species of fish she plans to raise. One of the main concerns is that each fish has enough water. The pet store will inspect the aquarium to make sure that the fish are being kept in a healthful environment.
She plans to raise fish and sell them to a local pet store. The tank is in the shape of a rectangular prism, 84 in long, 36 in wide, and 48 in deep.
