Rotary switches, single pole, single throw (SPST), rated at over 5 A, each measuring not more than 14.6 cm by 8.9 cm by 14.1 cm (described in statistical reporting number 8536.50.9025) Sewing machines of the household type, each weighing not more than 22.5 kg, having a touch screen control, a sewing light, a presser foot lifter and an automatic needle threader (described in statistical reporting number 8452.10.0090) Explanation:Because only one hexadecimal character is used to represent the subnet, that one character can represent 16 different values 0 through F. Athletic, recreational and sporting headgear comprising shells of polyvinyl chloride, polycarbonate plastic or acrylonitrile butadiene styrene, each with an inner liner of expanded polypropylene or expanded polystyrene, designed for use with bicycles (described in statistical reporting number 6506.10.6045)

Electronic AC passive infrared (PIR) motion sensing switches (described in statistical reporting number 8536.50.7000) Parts of swimming pool vacuum cleaners (described in statistical reporting number 8421.99.0040 prior to January 27, 2022; described in statistical reporting number 8421.99.0140 effective January 27, 2022) Blankets (other than electric blankets) of cotton, other than woven, each measuring at least 116 cm but not more than 118 cm on an edge (described in statistical reporting number 6301.30.0020) Explanation:The number of bits that are borrowed would be two, thus giving a total of 4 useable subnets:

There is a valuable lesson here: writing numbers in standard form is not always the way to go. It's all about simplicity of notation, but, at the end of the day, it pretty much boils down to a matter of personal preference (or your teacher's if you're writing a test). Push pins, of steel, designed for use in hydraulic solenoid control valves (described in statistical reporting number 8481.90.9040) Heat exchanger plates, cores, finned tubes, cones, shells, bonnets, flanges and baffles (described in statistical reporting number 8419.90.3000)

Electric motors, with an output of 18.65 W or more but not exceeding 37.5 W, with attached cables, designed for use in adjusting motor vehicle seats (described in statistical reporting number 8501.10.6080) DC electric motors, of an output of less than 18.65 W, other than brushless, measuring less than 38 mm in diameter (described in statistical reporting number 8501.10.4060) Power supplies for cable networks, that convert 120 V/60 Hz AC input to either 63 V AC or 87 V AC output, each measuring not more than 200 mm by 425 mm by 270 mm and weighing not more than 27.5 kg, containing printed circuit board assemblies, a transformer, and an oil filled capacitor (described in statistical reporting number 8504.40.8500) Solid valve lifters of steel, suitable for use solely or principally with spark-ignition internal combustion piston engines (other than for aircraft engines, marine propulsion engines or for vehicles of subheading 8701.20, or headings 8702, 8703 or 8704), each measuring 19 mm or more but not over 114 mm in length and 6 mm or more but not over 26 mm in diameter and weighing 20 g or more but not over 250 g (described in statistical reporting number 8409.91.9990) We said that the number b should be between 1 and 10. This means that, for example, 1.36 × 10⁷ or 9.81 × 10⁻²³ are in standard form, but 13.1 × 10¹² isn't because 13.1 is bigger than 10. We could, however, convert it to standard form by saying that:Supported catalysts with molybdenum compounds as the active substance for hydrogenation (described in statistical reporting number 3815.19.0000) Covers, of leather, designed for use with telecommunication devices (described in statistical reporting number 4205.00.8000) Ratchet winches designed for use with textile fabric strapping (described in statistical reporting number 8425.39.0100)
