Пошаговое объяснение:

а) Стоимость товара = 145тг × количество

б) S = 120 * t

S — расстояние

t — время

v — скорость = 120 км/ч

в) а = Р : 4

а — сторона квадрата

Р — периметр квадрата

г) S = πR²

S — площадь круга

π - число пи

R — радиус круга

Reading Task 1. Read the text and complete the tasks below. Most forms of charity mean providing basic items of necessity, such as food, water, clothing shelter, healthcare and else There are so many charitable organizations in the world today. They allow people to donate either directly or online, through websites Charitable organizations also include orphanages, food banks, religious institutes and hospitals for the poor. Donating things you don't use anymore is one of the forms of charity. Not everyone is lucky enough to have lots of toys or warm clothes for winter. Sometimes people simply can't find the job to earn enough money. Others are sick disabled or elderly and can't get around on their own. These are the cases when charity helps. If everyone made charity a part of their life and helped those who are in need, the world would become a better place to live. Mother Teresa once said: "To truly give charity, you must be free of selfishness!" And, it's true. The acts of charity come in many different forms If you have ever helped to plant a garden or gave your jar of coins to someone who needs it more than you, then you already know what charity is. However, true charity doesn't only mean giving out money and unwanted items to others. True charity starts with a kind word given by you to someone on a bad day, with a sincere smile and with love. 1. What did Mother Teresa say about charity, and why is it important? 2. How can charity involve more than just giving money or unwanted items? 3. Have you ever helped someone in a charitable way? Can you describe it? 4. What are some basic items of necessity that charitable organizations often provide? 5. How can a simple act of kindness, like a kind word or a smile, contribute to charity, according to the text?
