Question

Саша, Петя, и Вася играли в снежки. Первым кинул снежок Саша и попал в Петю. Каждый мальчик в ответ на каждый попавший в него снежок кидает 2 снежка. (не обязательно в того, кто в него попал) некоторые снежки ни в кого не попали. Всего было 4 поподания. Сколько снежков ни в кого не попало? Запишите решение и ответ. ​

Answer 1

Ответ:

Каждый мальчик в общем должен кинуть миниум 4 снежка, т.к. один

Кидает 1 снежок, тот отвечает двумя этот кидает 2×2=4 снежка

И допустим тот уже кидает 2×4=8 снежков

Вопрос не точный , но если при том что каждый кидал поровну раз то

8+4+2+1=15 снежков

15-4=11 промахов

Или

Если могут кидать по разному раз то:

1+2+4=7 7-4=3 промахов .

Ответ или 3 или 11.

Answer 2

Problem Analysis

In this problem, Sasha, Petya, and Vasya are playing a snowball fight. Sasha throws the first snowball and hits Petya. Each boy retaliates by throwing 2 snowballs for every snowball that hits them, regardless of who threw it. Some snowballs do not hit anyone. There were a total of 4 hits. We need to determine how many snowballs did not hit anyone.

Solution

Let's assume that the number of snowballs that did not hit anyone is represented by the variable x.

Since each hit results in 2 snowballs being thrown, we can calculate the total number of snowballs thrown by adding the number of hits to the number of snowballs that did not hit anyone:

Total snowballs thrown = Number of hits + Number of snowballs that did not hit anyone

We are given that there were 4 hits, so the equation becomes:

Total snowballs thrown = 4 + x

Now, let's consider the number of snowballs thrown by each boy: - Sasha threw the first snowball, which hit Petya. This means that Sasha threw 1 snowball. - Petya retaliated by throwing 2 snowballs for each snowball that hit him. Since Petya was hit once, he threw 2 snowballs. - Vasya also retaliated by throwing 2 snowballs for each snowball that hit him. Since Vasya was not hit, he did not throw any snowballs.

Therefore, the total number of snowballs thrown can be calculated as follows:

Total snowballs thrown = Sasha's snowballs + Petya's snowballs + Vasya's snowballs

Total snowballs thrown = 1 + 2 + 0 = 3

Now we can set up an equation using the total snowballs thrown:

4 + x = 3

To solve for x, we subtract 3 from both sides of the equation:

x = 3 - 4 = -1

However, since we cannot have a negative number of snowballs, we can conclude that there were no snowballs that did not hit anyone.

Answer

Therefore, the number of snowballs that did not hit anyone is 0.
