1. To find the greatest 3-digit number divisible by 6, 9, and 12, calculate their least common multiple (LCM): • 6 = 2 × 3, 9 = 3², 12 = 2² × 3 • LCM = 2² × 3² = 36 Divide the largest 3-digit number, 999, by 36: 999 ÷ 36 = 27.75 Round down to 27, multiply: 27 × 36 = 972. Thus, 972 is the largest 3-digiRead more

    To find the greatest 3-digit number divisible by 6, 9, and 12, calculate their least common multiple (LCM):
    • 6 = 2 × 3, 9 = 3², 12 = 2² × 3
    • LCM = 2² × 3² = 36
    Divide the largest 3-digit number, 999, by 36: 999 ÷ 36 = 27.75
    Round down to 27, multiply: 27 × 36 = 972.
    Thus, 972 is the largest 3-digit number divisible by 36.

  2. To find the smallest 4-digit number divisible by 3, 5, and 7, calculate their least common multiple (LCM): • 3, 5, 7 are prime, so LCM = 3 × 5 × 7 = 105. Divide the smallest 4-digit number, 1000, by 105: 1000 ÷ 105 = 9.52. Round up to 10, multiply: 10 × 105 = 1050. Thus, 1050 is the smallest 4-digitRead more

    A laboratory thermometer is not suitable for measuring body temperature because it is designed to measure a wide range of temperatures with less sensitivity. Body temperature requires a precise and narrower range, typically around 35°C to 42°C. Laboratory thermometers often have a scale that is not fine enough for accurate body temperature readings. For this purpose, a clinical thermometer, which is specifically calibrated for the narrow temperature range of the human body, is used.

  4. A laboratory thermometer with 50 divisions between 0°C and 100°C means each division represents a temperature increment of 2°C. This is determined by dividing the total temperature range of 100°C (from 0°C to 100°C) by the number of divisions (50). Thus, each division on the thermometer correspondsRead more

    A laboratory thermometer with 50 divisions between 0°C and 100°C means each division represents a temperature increment of 2°C. This is determined by dividing the total temperature range of 100°C (from 0°C to 100°C) by the number of divisions (50). Thus, each division on the thermometer corresponds to a 2°C increase, allowing for the measurement of temperatures within this range with a resolution of 2°C per division.

  5. When someone mentions a fever of 101 degrees, she is most likely referring to the Fahrenheit scale. A temperature of 101°F is considered a common fever range for humans. In contrast, 101°C would be extremely high and life-threatening, as it is close to the boiling point of water. Therefore, 101 degrRead more

    When someone mentions a fever of 101 degrees, she is most likely referring to the Fahrenheit scale. A temperature of 101°F is considered a common fever range for humans. In contrast, 101°C would be extremely high and life-threatening, as it is close to the boiling point of water. Therefore, 101 degrees on the Celsius scale is not a typical fever but rather a serious medical emergency.
