Question

Ты научишь неправильные дроби, смешанные числа. 1 Реши задачу. При утечке из крана воды за сутки набегает примерно 10 литров — целое ведро. Сколько вёдер воды утечёт без пользы за неделю? Месяц? Какой вред это наносит природе? Если 1 кубический метр воды стоит 70 тенге, то как утечка воды отразится на семейном бюджете?​

Answer 1

Ответ:

За ниделю- 70 литров. За месяц(30 дней) - 300 литров. Водные ресурсы планеты очень исчерпаны, если каждый человек хоть по 1 литру будет тратит без надобности (или утечка) то водных ресурсы так изчерпаются что не хватит для всего живого на планете. Будет всемирное потепление (т. к. вода держит тепло и холод, тем самым не давая температуре земли сильно понижается или повышатся). 70:1000л=0,07 тенге за 1 литр. За месяц- 30*0,07=2,1 тенге.

Объяснение:

1 м³ = 1000 литров.

Understanding the Problem

To solve this problem, we need to determine the amount of water that will be wasted over a week and a month due to a leaky faucet. We also need to calculate the environmental impact of this water waste and how it will affect a family's budget if the cost of 1 cubic meter of water is 70 tenge.

Calculating Water Waste

Given that the leaky faucet wastes approximately 10 liters of water per day, we can calculate the amount of water wasted over a week and a month.

- Water wasted over a week: Since there are 7 days in a week, the total amount of water wasted over a week is 10 liters/day * 7 days/week = 70 liters/week. - Water wasted over a month: Assuming there are 30 days in a month, the total amount of water wasted over a month is 10 liters/day * 30 days/month = 300 liters/month.

Therefore, the leaky faucet will waste 70 liters of water over a week and 300 liters of water over a month.

Environmental Impact

Water waste can have a negative impact on the environment. It can lead to water scarcity, increased energy consumption for water treatment and distribution, and pollution of water bodies. The environmental impact of water waste depends on various factors, such as the availability of water resources in the region and the efficiency of water management systems.

Impact on Family Budget

To calculate the impact on the family budget, we need to know the cost of 1 cubic meter of water, which is given as 70 tenge.

- Cost of water wasted over a week: Since 1 cubic meter is equal to 1000 liters, the cost of water wasted over a week is (70 tenge/1 cubic meter) * (70 liters/week / 1000 liters/cubic meter) = 4.9 tenge/week. - Cost of water wasted over a month: Similarly, the cost of water wasted over a month is (70 tenge/1 cubic meter) * (300 liters/month / 1000 liters/cubic meter) = 21 tenge/month.

Therefore, the leaky faucet will cost the family approximately 4.9 tenge per week and 21 tenge per month.

Please note that the actual cost may vary depending on the specific water rates in your region.
