Question

На горе Блоксберг на троне из печных ухватов восседала Главная ведьма. На подлокотники ее трона ушло 8 ухватов, на ножки трона -4 ухвата. Широкое сиденье трона было сделано из 36 ухватов, что составляло половину ухватов, из которых была сделана удобная спинка. Найду массу трона Главной ведьмы, если масса одного ухвата равна 2 кг 15 г.

Answer 1

2кг15г=2015г

36*2=72ухв- ушло на спинку

8+4+36+72= 120ухв- столько ухватов ушло на трон

2015*120= 241800г=241кг800г-масса трона

Answer 2

Calculation of the Throne's Mass

To find the mass of the throne, we need to calculate the total mass of all the components mentioned in the question. Let's break down the information provided:

- Armrests: The armrests of the throne required 8 handgrips or "ухватов" each. - Legs: The legs of the throne required 4 handgrips each. - Seat: The wide seat of the throne was made up of 36 handgrips, which constituted half of the total handgrips used. - Backrest: The remaining handgrips were used to create a comfortable backrest.

Given that the mass of one handgrip or "ухват" is 2 kg 15 g, we can calculate the mass of the throne as follows:

- Mass of the armrests: 8 handgrips * (2 kg + 15 g) = 8 * 2.015 kg - Mass of the legs: 4 handgrips * (2 kg + 15 g) = 4 * 2.015 kg - Mass of the seat: 36 handgrips * (2 kg + 15 g) = 36 * 2.015 kg - Mass of the backrest: Total mass of handgrips - (mass of armrests + mass of legs + mass of seat)

To find the mass of the backrest, we need to subtract the sum of the masses of the armrests, legs, and seat from the total mass of the handgrips.

Let's calculate the mass of the throne step by step:

1. Calculate the mass of the armrests: 8 * 2.015 kg = 16.12 kg 2. Calculate the mass of the legs: 4 * 2.015 kg = 8.06 kg 3. Calculate the mass of the seat: 36 * 2.015 kg = 72.54 kg 4. Calculate the mass of the backrest: Total mass of handgrips - (mass of armrests + mass of legs + mass of seat)

To find the total mass of the handgrips, we need to multiply the mass of one handgrip by the total number of handgrips used in the throne:

- Total number of handgrips used = Number of handgrips used for the armrests + Number of handgrips used for the legs + Number of handgrips used for the seat = 8 + 4 + 36 = 48 handgrips

5. Calculate the total mass of the handgrips: 48 * (2 kg + 15 g) = 48 * 2.015 kg

Finally, we can calculate the mass of the backrest:

- Mass of the backrest = Total mass of handgrips - (mass of armrests + mass of legs + mass of seat)

Now, let's calculate the mass of the backrest and the total mass of the throne:

- Mass of the backrest: Total mass of handgrips - (mass of armrests + mass of legs + mass of seat) - Total mass of the throne: Mass of the armrests + Mass of the legs + Mass of the seat + Mass of the backrest
