Перед ремонтом зоопарка животных вывезли в специальных автофургонах.Было сделано 150 рейсов. Каждым рейсом отправлялось одно и то же количество животных.После ремонта зоопарка сделали 170 таких же рейсов и привезли на 800 животных больше,чем до ремонта.Сколько животных прибыло в зоопарк после ремонта?

Answer 1

1)170-150=на 20 рейсов больше-после ремонта.

2)800:20=40животных-за один рейс.

3)150*40=6000животных-перед ремонтом.

4)170*40=6800животных-после ремонта.

Answer 2

1)170-150=20(автофургонов) на столько автофургонов было больше

2)800:20=40(ж) было в 1 фургоне

3) 170*40= 6800(ж)было перевезено после ремонта

Answer 3

Calculation of Animals Arriving at the Zoo After Renovation

Before the zoo renovation, 150 trips were made to transport the animals, with the same number of animals transported on each trip. After the renovation, 170 similar trips were made, and 800 more animals were brought in than before the renovation.

Let's denote: - x: the number of animals transported on each trip before the renovation. - y: the total number of animals brought in after the renovation.

We can set up the following equations based on the given information: 1. Before renovation: 150 trips * x animals per trip = total number of animals before renovation. 2. After renovation: 170 trips * x animals per trip = total number of animals before renovation + 800.

We can solve these equations to find the value of y.

Solution

1. Before renovation: 150 trips * x animals per trip = total number of animals before renovation. 2. After renovation: 170 trips * x animals per trip = total number of animals before renovation + 800.

By solving these equations, we can find the value of y.

Calculation

150x = Total number of animals before renovation 170x = Total number of animals before renovation + 800

Subtracting the first equation from the second: 170x - 150x = 800 20x = 800 x = 40

Now that we have found the value of x (the number of animals transported on each trip before the renovation), we can calculate the total number of animals brought in after the renovation using the value of x.

Total Animals Arriving After Renovation

Using the value of x: 170 trips * 40 animals per trip = 6800 animals before renovation + 800 = 7600 animals.

After the renovation, 7600 animals arrived at the zoo.
