Finally, there it is !! Our exercise is finish ! Have fun !

1) Kévin plays at SUPER MARIO WORLD on his Gamebox color red and blue. He made a game and lost at the end of the first level. He won 189 coins in recolt them on flying cubes and dinish his game in 120 seconds. We know that one time the game finished, he win 1 coin/leaved seconds and that at the beginning he start with a total of 300 seconds, calculate the number of coins he won in all.

2) Kevin made 10 others games in wiches he won :
1st : 453
2nd : 399
3rd : 346
4th : 402
5th : 309
6th : 469
7th : 445
8th : 390
9th : 404
10th : 328
Calculate the median, the mode, the average, the first quartil and the third one.
Make a table of all the results from the smallest to the biggest it could help you.

Martin Dupont walked on the moon forty years ago. At 1969, his mass was 90 kilos with his moon suit. Until, he took 26 kilos. Knowing that heavyness intensity on Earth is 9,81 Newtons and that it is 6 times more than Moon, calculate the weight of Martin Dupont on the moon in 2009.

At the end of his trip on the moon, Martin Dupont return on Earth. He is happy to breath the breeze once again!

What is the composition of the breeze?

How many protons and electrons are there in each element ?

What are the differents coats of an atom ?

How many protons and electrons are there on the last electronic coat of each element ?

Phill and Bob, two friends are talking. Bob can’t remember how old is his friend. To help him, Phill gives him a hint:

” I’m twice as old as you were when I was as old as you are now. And when you’ll be as old as I am now, our combined ages will be of 63 years .”

How old are Bob and Phill ?

Good luck

A family of five persons goes to a restaurant for Christmas. They want to eat snails and frogs.

The mother, Yvette oders six snails and eight frogs. The father, Jean-Claude, takes four frogs more his wife and one-third of his frogs in snails. His daughter, Ginette, wants to eat three snails less than his father and two times less frogs than her mother. However, she exchanges two of her frogs with snails. Her older brother, Gérard, would like more snails than his father but less than his mother. He orders two frogs less than his sister too. The youngest, Gertrude, wants two snails less than her mother and half frogs of her father. But she isn’t hungry, so she gives three of her frogs to her brother.

How many snails and frogs ate each person ?

We know that two snails cost three euros and one frog costs two euros. So at the end, how much the family has to pay ?

Good luck !

Then, we have different exercices for you, two of maths and one of physics :

Exercice 1 :

In the market, ducks cost £5 each, hens cost £1 each, and baby chickens were 20 for £1. Cindy bought at least one of each, 100 birds altogether, for a total amount of £100. Then How many of each did Betty buy ?

We will send the next laster. Thank you Bye.

I think the walls colours of my classroom are too ugly. So I bought 2 orange paint pots and 1 green paint pots for a global price of £91.

A friend did the same but he bought 3 orange paint pots and 4 green paint pots for a global price of £204.

We lost the bill and we want to know orange and green paint pots prices.

The orange paint pot price is noted x.

The green paint pot price is noted y.

S {2x + 1y = 91

{3x + 4y = 204

Now my classroom is the most beautiful of the worl
