Step-by-step solution

4 steps

1.1 Use TABLE 1 above to choose the unit/symbol from COLUMN B that matches the concept in COLUMN A. Write only the letter (A-E) next to the question numbers.

  • 1.1.1 Capacity: Capacity is a measure of volume. The unit for volume in Column B is millilitres. The answer is C\boxed{\text{C}}.

  • 1.1.2 Area: Area is measured in square units. The unit for area in Column B is m2\text{m}^2. The answer is D\boxed{\text{D}}.

  • 1.1.3 Height: Height is a measure of length. The unit for length in Column B is millimetres. The answer is B\boxed{\text{B}}.

  • 1.1.4 Temperature: Temperature is measured in degrees Celsius. The unit for temperature in Column B is °C\text{°C}. The answer is A\boxed{\text{A}}.

1.2 Dan wants to watch a movie. The movie starts at 21:00 and is 1 hour 45 minutes long.

1.2.1 Write 21:00 in a 12-hour format.

  1. Convert 21:00 from 24-hour format to 12-hour format.

    Since 21>1221 > 12, subtract 12 from 21.

    21−12=921 - 12 = 9

    The time is 9:00 PM\boxed{9:00 \text{ PM}}.

    1.2.2 What time will the movie end?

  2. Add the movie duration to the start time.

    Start time: 21:00
    Duration: 1 hour 45 minutes

    21:00+1 hour 45 minutes=22:4521:00 + 1 \text{ hour } 45 \text{ minutes} = 22:45

    The movie will end at 22:45\boxed{22:45}.

    1.3 Connie weighs 94 kg and is concerned about her weight. She has joined a gym and wants to lose some weight. Convert her weight to grams.

  3. Use the conversion factor 1 kg=1000 g1 \text{ kg} = 1000 \text{ g}.

  4. Multiply Connie's weight in kilograms by the conversion factor.

    94 kg×1000 g/kg=94000 g94 \text{ kg} \times 1000 \text{ g/kg} = 94000 \text{ g}

    Connie's weight in grams is 94000 g\boxed{94000 \text{ g}}.
