Question

Пожалуйста побыстрей 20 баллов.Имеется 50 камней массы которых равны 185 , 186 , 187 , .... 234 кг . Можно ли увезти их на семи полуторатонных грузовиках?

Answer 1

Ответ:

сначала нужно найти сумму - это арифметическая прогрессия

S = (a1 + an )/2 * n

(185 + 234 )/2 *50 =  10 475 (кг) ( здесь число 50 - это количество членов прогрессии)

7 * 1,5  = 10, 5 т  (10 500 кг) -столько можно увести на 7 грузовиках

Сравниваем: 10 475 кг < 10500  кг - значит увести можно

Answer 2

Can 50 stones weighing between 185 kg and 234 kg be transported on seven 1.5-ton trucks?

To determine if it is possible to transport 50 stones weighing between 185 kg and 234 kg on seven 1.5-ton trucks, we need to calculate the total weight of the stones and compare it to the maximum weight capacity of the trucks.

Let's calculate the total weight of the stones first. We have 50 stones with weights ranging from 185 kg to 234 kg. To find the average weight, we can add the minimum and maximum weights and divide by 2:

(185 kg + 234 kg) / 2 = 419 kg / 2 = 209.5 kg

So, the average weight of the stones is approximately 209.5 kg.

Next, we can calculate the total weight of all 50 stones by multiplying the average weight by the number of stones:

209.5 kg * 50 = 10,475 kg

Therefore, the total weight of the stones is 10,475 kg.

Now, let's compare this weight to the maximum weight capacity of the seven 1.5-ton trucks. One ton is equal to 1,000 kg, so a 1.5-ton truck can carry:

1.5 tons * 1,000 kg/ton = 1,500 kg

Therefore, the maximum weight capacity of each truck is 1,500 kg.

To determine if the stones can be transported on the trucks, we need to divide the total weight of the stones by the maximum weight capacity of each truck:

10,475 kg / 1,500 kg = 6.983

The result is approximately 6.983, which means that it is not possible to transport the 50 stones on seven 1.5-ton trucks. The total weight of the stones exceeds the maximum weight capacity of the trucks.

Therefore, it is not possible to transport the 50 stones weighing between 185 kg and 234 kg on seven 1.5-ton trucks
