Question

Подскажите пожалуйста Выполнить действия и вырази в указанных единицах. (8м2дм-43дм6см)×70—в метрах и дециметрах (6ч32+18ч7мин):17—в часах минутах (3т4ц16кг-32ц9кг)×760—в тоннах и килограммах (25а5М2+4га55М2):152—в арах квадратных метрах. за ранние спасибо.

Answer 1

( 8 м 2дм - 43 дм 6 см) * 70 =26880 см =2688 дм = 268 м 8 дм

(6 ч 32 мин +18 ч 7 мин) :17 =87 мин =1 ч 27 мин

(3 т 4 ц 16 кг -32 ц 9 кг) * 760 =157320 кг =157 т 320 кг

(25 а 5 м2 + 4 га 55 м2) :152 =280 м2 =2 а 80 м2

Answer 2

Calculation 1: (8м2дм-43дм6см)×70 in meters and decimeters

To perform the calculation (8м2дм-43дм6см)×70, we need to convert the measurements to a consistent unit. Let's convert everything to decimeters.

1 meter (м) = 10 decimeters (дм) 1 decimeter (дм) = 10 centimeters (см)

Given: 8 meters (м) = 80 decimeters (дм) 2 decimeters (дм) = 20 centimeters (см) 43 decimeters (дм) = 430 centimeters (см) 6 centimeters (см) = 6 centimeters (см)

Now we can perform the calculation: (80дм + 20см - 430см - 6см) × 70

Simplifying: (80дм - 410см) × 70

Converting back to meters and decimeters: (8м - 41дм) × 70

Calculating: (8 - 41/10) × 70 = (8 - 4.1) × 70 = 3.9 × 70 = 273 decimeters

Converting to meters: 273 decimeters = 27.3 meters

Therefore, the result of (8м2дм-43дм6см)×70 is 27.3 meters or 273 decimeters.

Calculation 2: (6ч32 + 18ч7мин) ÷ 17 in hours and minutes

To perform the calculation (6ч32 + 18ч7мин) ÷ 17, we need to convert the minutes to hours.

Given: 6 hours (ч) = 6 hours (ч) 32 minutes (мин) = 32 minutes (мин) 18 hours (ч) = 18 hours (ч) 7 minutes (мин) = 7 minutes (мин)

Now we can perform the calculation: (6ч + 32мин + 18ч + 7мин) ÷ 17

Simplifying: (6ч + 18ч) + (32мин + 7мин) ÷ 17

Calculating: 24ч + 39мин ÷ 17

Converting minutes to hours: 24ч + (39 ÷ 60)ч

Calculating: 24ч + 0.65ч = 24.65ч

Converting to hours and minutes: 24.65 hours = 24 hours and 39 minutes

Therefore, the result of (6ч32 + 18ч7мин) ÷ 17 is 24 hours and 39 minutes.

Calculation 3: (3т4ц16кг-32ц9кг)×760 in tons and kilograms

To perform the calculation (3т4ц16кг-32ц9кг)×760, we need to convert the measurements to a consistent unit. Let's convert everything to kilograms.

1 ton (т) = 100 centners (ц) 1 centner (ц) = 100 kilograms (кг)

Given: 3 tons (т) = 300 centners (ц) 4 centners (ц) = 400 kilograms (кг) 16 kilograms (кг) = 16 kilograms (кг) 32 centners (ц) = 3200 kilograms (кг) 9 kilograms (кг) = 9 kilograms (кг) 760 is already in kilograms (кг)

Now we can perform the calculation: (300ц + 400кг + 16кг - 3200кг - 9кг) × 760

Simplifying: (300ц - 2793кг) × 760

Converting back to tons and kilograms: (3т - 27ц93кг) × 760

Calculating: (3 - 27/100)т × 760 = (3 - 0.27)т × 760 = 2.73т × 760 = 2074.8 kilograms

Converting to tons: 2074.8 kilograms = 2.0748 tons

Therefore, the result of (3т4ц16кг-32ц9кг)×760 is 2.0748 tons or 2074.8 kilograms.

Calculation 4: (25а5М2 + 4га55М2) ÷ 152 in square aras and square meters

To perform the calculation (25а5М2 + 4га55М2) ÷ 152, we need to convert the measurements to a consistent unit. Let's convert everything to square meters.

1 ara (а) = 100 square meters (м2) 1 hectare (га) = 100 ares (а)

Given: 25 ares (а) = 2500 square meters (м2) 5 square meters (м2) = 5 square meters (м2) 4 hectares (га) = 400 ares (а) = 40000 square meters (м2) 55 square meters (м2) = 55 square meters (м2) 152 is already in square meters (м2)

Now we can perform the calculation: (2500м2 + 5м2 + 40000м2 + 55м2) ÷ 152

Simplifying: (2500м2 + 40005м2) ÷ 152

Calculating: 42505м2 ÷ 152 = 279.9342 square meters

Converting to aras: 279.9342 square meters = 2.799342 ares

Therefore, the result of (25а5М2 + 4га55М2) ÷ 152 is 2.799342 ares or 279.9342 square meters.

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