Bonjour pouvez vous m aider svp : Le niveau d'eau d'une rivière est de 1,5 m. On a constaté, lors d'une nuit
de fortes pluies, qu'à partir de minuit,
sa hauteur augmentait de 4 cm par
heure. On note u, le niveau d'eau au
bout de n heures écoulées après minuit.
1. Calculer le niveau d'eau à 4 h du
matin.
2. Déterminer la relation de récur-
rence qui caractérise la suite (un).

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

step-by-step explanation:

a child is 12 years old, and his father is 32 years older. in how many years will the age of the father be 2 times the age of the child?

******************

this needs to be the answer format, or else your answer is incomplete.

if the number of years is x, then the equation is

in __ years

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
