Bonsoir j'ai quatre exercices que je ne comprend pas, voici le premier. On considère une pyramide ayant pour base un triangle ABC rectangle en B tel que AB = 12 m et BC = 15 m. La hauteur [SA] de la pyramide mesure 12 m.

Calculer le volume de cette pyramide.
On donnera la réponse suivie de l'unité qui convient.
_
On multiplie toutes les longueurs de cette pyramide par 3.

Quel est le nouveau volume de la pyramide ?
On donnera la réponse suivie de l'unité qui convient.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

2/3
