La figure suivante représente la façade d'une grande case de St-Pierro, Les trois fenetres ont la même dimension (2.00 mx 1.00m)
La porte mesure 2.00 m x 2.40 m
Une entreprise est chargé de peindre cette façade.
Un bidon de peinture de 10 L cote 75 € et permet de couvrir une surface de 50 m
On souhaite passer 2 couches de peinture sur la façade de cette case Calculer le
nombre de bidons nécessaires ainsi que le coût de la peinture,
Dans cet exercice, toute trace de recherche, même non aboutie sera prise en compte dans l evaluation​

step-by-step explanation:

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
