Question

7 un radeau peut accueillir une charge maximale de 250 kg. malik et ses 5 camarades peuvent-ils y prendre place tous ensemble ?
masse de malik et de ses camarades
malik : 54 000 g
charlie : 43 600 g
vincent : 41 300 g
victoria : 45 kg
antoine : 49 250 g
salma : 37,2 kg

Explanation:

Step1: Convert all masses to kg

• Malik: \( 54000\ g=\frac{54000}{1000}\ kg = 54\ kg \)
• Charlie: \( 43600\ g=\frac{43600}{1000}\ kg = 43.6\ kg \)
• Vincent: \( 41300\ g=\frac{41300}{1000}\ kg = 41.3\ kg \)
• Antoine: \( 49250\ g=\frac{49250}{1000}\ kg = 49.25\ kg \)

Step2: Sum all masses

Total mass \( = 54 + 43.6 + 41.3 + 45 + 49.25 + 37.2 \)
\( = 54+43.6 = 97.6 \)
\( 97.6+41.3 = 138.9 \)
\( 138.9+45 = 183.9 \)
\( 183.9+49.25 = 233.15 \)
\( 233.15+37.2 = 270.35\ kg \)

Step3: Compare with max load

Max load is \( 250\ kg \). Since \( 270.35>250 \)

Answer:

No, Malik and his 5 comrades cannot all fit together on the raft.
