The table shows the rate at which water is being pumped into a swimming pool. Time (min) Amount (gal) 2 The unit rate is 44 4 88 5 110 12 264 Use the unit rate and the amount of water pumped after 12 minutes to find how much water will have been pumped into the pool after 13 minutes. Complete the explanation of your reasoning. 1 2 gal/min. So 11/ gal/min. So 1 minutes after 12 minutes, an additional gallons

The hydraulic diameter of a rectangular duct is calculated using the equation D = 4, where Dr is the hydraulic diameter, A is the cross-sectional area of the duct and p is the perimeter of the duct. If the dimensions of the rectangular duct are a = 26 cm+0.4 mm, and b = 33 cm +1.3 mm, what is the uncertainty of D, in percentage format? Enter the answer as a numerical value without any sign. Retain 3 significant figures. a

Density is how much you have in a volume. If I put 14.76 kilogram(s) of carbon dioxide in an empty 2.11 m3 bottle, what is the density of the gas after filling it? Round to nearest 2 decimals.

DEA agents watch drug smugglers load cocaine onto a fishing boat in a Mexican river to transport it down the river to the ocean, and then to Miami. To estimate how much cocaine was loaded, they measure how much further the boat sinks into the water after being loaded. If the boat’s area at the waterline is 50 m2 and it sinks by 2 cm, how much cocaine was loaded?

Below is the calculator result for the operation indicated. Enter the answer to the correct number of significant figures for this calculation, using the rules for significant figures. 2.15648 0.0056892 = 2.1507908

A rectangular swimming pool is (7.50x10^1) ft wide and (1.750x10^2) ft long. What is the area of the pool in square meters? Use the conversion 1 m = 3.28 ft. Your numerical answer requires the correct number of significant digits.

8.36 grams of a mystery substance of food with a molar mass of 149.36 g/mol is burned in a bomb calorimeter. The water in the bomb calorimeter absorbs 105,961 Joules from the burning of the substance. Calculate the heat of combustion of the mystery substance in kJ/mol. (Please input your answer as a negative number.) (DO NOT PUT UNITS IN YOUR ANSWER.) Assume that all of the heat lost by the substance is transferred to the water and no heat is lost to the surroundings.

Water flows into a swimming pool at the rate of 12 gal/min. The pool is 16 ft wide, 32 ft long and 6.0 ft deep. How long does it take to fill? (1 U.S. gallon = 231 cubic inches)

Convert the total number of gallons of gas  2.90 per gallon (round trip 452 miles) to liters of gas.

A group of students wish to determine, experimentally, the bulk density of an unknown material. To determine this amount, the students measured the diameter, height, and mass of various cylinders. These values ​​appear in the table below. Determine: a) The volume of the cylinders that appears in the following table. b) The graph of mass vs. volume.
