(Il existe d\u2019autres possibilit\u00e9s de trouver les r\u00e9ponses)<\/strong><\/h5>

R\u00e9ponse 1
<\/strong>Soit x la longueur et y la largeur de votre emballage<\/p>

\"\"<\/p>

Dans le premier cas le p\u00e9rim\u00e8tre est\u00a0: 2x + y = 140
Dans le deuxi\u00e8me cas, le p\u00e9rim\u00e8tre est\u00a0:
2y + x = 130 donc x = 130 \u2013 2 y<\/p>

En le pla\u00e7ant dans la premi\u00e8re \u00e9quation cela donne\u00a0:
2(130 \u2013 2 y) + y = 140
260 \u2013 4 y + y = 140 => 3y = 120 donc y = 40 et x = 130 \u2013 80 = 50<\/p>

R\u00e9ponse 2
<\/strong>Soit x le nombre de plateaux faits pas Louise.
L\u2019\u00e9quation devient\u00a0:
25 (x + 1) = 30 x
25x + 25 = 30 x => 5 x = 25 => x = 5
Louise aura fait 5 plateaux au bout de 150 minutes et Camille 6<\/p>

R\u00e9ponse 3
<\/strong>Le nombre de possibilit\u00e9s est de 6\u00a0! = 6 factoriel , soit 6*5*4*3*2*1 = 720<\/p>

R\u00e9ponse 4
<\/strong>Soit x le nombre de collaboratrices et de collaborateurs
x\/2 + x\/4 + x\/7 + 3 = x
En mettant tout avec le m\u00eame d\u00e9nominateur, cela donne\u00a0:
14x\/28 + 7x\/28 + 4x\/28 + 84\/28 = 28x\/28
14x + 7x + 4x + 84 = 28 x
25x + 84 = 28x => 3x = 84 => x = 28<\/p>

R\u00e9ponse 5
<\/strong>La logique est la suivante\u00a0:
Le chiffre est multipli\u00e9 par 2, plus un. Le r\u00e9sultat est multipli\u00e9 par 2, plus un, etc.:
3*2 + 1 = 7
7*2 + 1 = 15
15*2 + 1 = 31<\/p>

R\u00e9ponse 6
<\/strong>Si 6 personnes produisent 1800 plateaux en 4 semaines,
6 personnes produisent 450 plateaux par semaines, donc une personne produit 75 plateaux par semaine.
7 personnes vont produire 75 * 7 = 525 plateaux par semaine, donc 525 * 3 = 1575 en 3 semaines.
C\u2019est insuffisant, il faudra planifier 8 personnes pour produire 1800 plateaux.<\/p>

R\u00e9ponse 7
<\/strong>Soit x la surface de la zone de conditionnement
(168\/192)\u00a0 =\u00a0 (252\/x)
168 x = 252 * 192 = 48’394, donc x = (48’394\/168)\u00a0 = 288
La surface totale est \u00e9gale \u00e0\u00a0: 168 + 252 + 192 + 288 = 900
Le c\u00f4t\u00e9 du carr\u00e9 est donc de 30 m
La largeur des locaux de \u00abr\u00e9ception\/vestiaire\u00bb et \u00ablavage\u00bb est de (420\/900)\u00a0 * 30 = 14 m
La largeur des locaux \u00abconditionnement\u00bb et \u00abstockage st\u00e9rile\u00bb est de: 30 \u2013 14 = 16 m
La longueur du local \u00abr\u00e9ception\/vestiaire\u00bb et du local \u00abstockage st\u00e9rile\u00bb est de: (168\/14) = 12 m
La longueur du local \u00ablavage\u00bb et du local \u00a0\u00abconditionnement\u00bb est de : 30 \u2013 12 = 18 m<\/p>

R\u00e9ponse 8
<\/strong>Soit x la dur\u00e9e du cycle de st\u00e9rilisation \u00e0 la vapeur d\u2019eau
L\u2019\u00e9quation devient\u00a0: 1\/4x + 5 + 2\/3x = x
En mettant tout sous le m\u00eame d\u00e9nominateur: (3x\/12) + (60\/12) + (8x\/12)\u00a0 = (12x\/12)
11 x + 60 = 12 x => x = 60
Donc le cycle se terminera \u00e0 10:39 heures + 40 minutes (2\/3 de 60), donc \u00e0 11 :19 heures<\/p>

R\u00e9ponse 9
<\/strong>La nombre de partie est de 23.
Si le nombre de joueur (N) \u00e9tait diff\u00e9rent, la r\u00e9ponse serait\u00a0: N \u2013 1<\/p>

R\u00e9ponse 10
<\/strong>Un IB TIR est un indicateur biologique \u00e0 temps d\u2019incubation r\u00e9duite (moins de 7 jours). La norme concern\u00e9e est la EN ISO 11138-8 pour les indicateurs biologiques \u00e0 temps r\u00e9duit pour la st\u00e9rilisation \u00e0 la chaleur humide et pour la st\u00e9rilisation \u00e0 l\u2019oxyde d\u2019\u00e9thyl\u00e8ne (ne concerne pas la st\u00e9rilisation VH2O2).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"no-sidebar","site-content-layout":"page-builder","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"disabled","ast-breadcrumbs-content":"","ast-featured-img":"disabled","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"forum_cat":[1028],"parution":[],"page_sommaire":[],"class_list":["post-26198","forum","type-forum","status-publish","hentry","forum_cat-edition-2-2021"],"acf":[],"yoast_head":"\nProposition de solutions -
