Question

Вырази; в миллиметров : 3 см 5 мм , 2 дм 3 см , 4 м 3 дм ; в квадратных метрах : 3 800 дм 2, 1 км 2; в минутах: 2 400 с , 3 ч 50 мин , 2 ч 30 мин. ПОМОГИТЕ ПЛИЗ!!!

Answer 1

3 см 5 мм = 35 мм, 2 дм 3 см = 230 мм, 4м 3 дм = 4300 мм
3800 кв.дм = 38 кв.м, 2,1 кв.км =210000 кв.м
2400 с = 40 мин, 3 ч 50 мин =230 мин, 2 ч 30 мин = 150 мин

Converting Measurements:

To convert the given measurements to millimeters, we can use the following conversion factors:

- 1 centimeter (cm) = 10 millimeters (mm) - 1 decimeter (dm) = 100 millimeters (mm) - 1 meter (m) = 1000 millimeters (mm)

Let's convert the measurements:

1. 3 cm 5 mm: - 3 cm = 3 * 10 mm = 30 mm - 5 mm = 5 mm - Therefore, 3 cm 5 mm is equal to 35 mm.

2. 2 dm 3 cm: - 2 dm = 2 * 100 mm = 200 mm - 3 cm = 3 * 10 mm = 30 mm - Therefore, 2 dm 3 cm is equal to 230 mm.

3. 4 m 3 dm: - 4 m = 4 * 1000 mm = 4000 mm - 3 dm = 3 * 100 mm = 300 mm - Therefore, 4 m 3 dm is equal to 4300 mm.

Converting Area Measurements:

To convert the given area measurements to square meters, we need to square the given measurements and then convert them to square meters.

1. 3,800 dm^2: - 3,800 dm^2 = 3,800 * (100 mm)^2 = 3,800 * (100 mm * 100 mm) = 3,800 * (10,000 mm^2) = 38,000,000 mm^2 - 1 square meter (m^2) = 1,000,000 mm^2 - Therefore, 3,800 dm^2 is equal to 38 square meters.

2. 1 km^2: - 1 km^2 = 1 * (1000 m)^2 = 1 * (1000 m * 1000 m) = 1 * (1,000,000 m^2) = 1,000,000 m^2 - Therefore, 1 km^2 is equal to 1,000,000 square meters.

Converting Time Measurements:

To convert the given time measurements to minutes, we can use the following conversion factors:

- 1 second (s) = 1/60 minute (min) - 1 hour (h) = 60 minutes (min)

1. 2,400 s: - 2,400 s = 2,400 * (1/60) min = 40 min - Therefore, 2,400 s is equal to 40 minutes.

2. 3 h 50 min: - 3 h = 3 * 60 min = 180 min - 50 min = 50 min - Therefore, 3 h 50 min is equal to 230 minutes.

3. 2 h 30 min: - 2 h = 2 * 60 min = 120 min - 30 min = 30 min - Therefore, 2 h 30 min is equal to 150 minutes.

I hope this helps! Let me know if you have any further questions.
