Answers
Answer:
A company charges. 50/sq ft to paint a billboard. Input length(l) and breadth(b) of a board in fees parameters to the main() function. Calculate the area and total cost to paint it.In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number),[1] sign change,[2] and negation.[3] For a real number, it reverses its sign: the additive inverse (opposite number) of a positive number is negative, and the additive inverse of a negative number is positive. Zero is the additive inverse of itself.
6 ways people waste water without realising it
3
The average person wastes up to 30 gallons of water every day. In a world where so much of the population lack access to safe water and sanitation, it's shameful that we still waste so much water, especially in cities like ours. And let's admit it – we've all had a role to play.
Down the drain
One of the most common ways in which people waste water is by leaving the water running when brushing their teeth, shaving or doing the dishes. Turn the tap off as soon as you start brushing, shaving or doing the dishes. For washing the dishes, fill one sink with clean rinse water and one with soapy water. For rinsing your mouth, simply keep a glass of water at hand instead of drinking directly from the tap.

Flush wisely
Your toilet could be flushing away up to five gallons of water every time you flush. People tend to flush every time the toilet is used, which can waste hundreds of gallons a week. If it's just urine, flush every two or three times to save water.
Washing the car
Using a hose to wash the car can use up gallons of water. If you leave the hose running, you can end up wasting almost 150 gallons of water. However, if you use a simple bucket and sponge to scrub the car, it will not just get your car clean, but will also give you some good exercise while saving water.
5
Long showers
Did you know that taking long showers wastes five to 10 gallons of water? You can either invest in a low-flow shower head, aim for quick showers or simply bathe using a bucket and pail. A water-efficient shower head can help save nearly 750 gallons of water a month.
Leaky faucets and toilets
Leaky tank valves draining water into the toilet waste up to 1,000 gallons of water a month. One of the most common culprits of water wastage at home is the leaky faucet and toilet. It may seem insignificant but the little drips can actually add up. A constantly leaking toilet can waste up to 22 gallons of water every day which adds up 8,000 gallons of water in a year. If you notice a leaky pipe, faucet, or toilet, get it fixed immediately.
