surface area of the triangular prism = 7×10 + 7.62 × 10 + 2× 0.5 × 3×7 + 3×10 cm²
=> 70 + 76.2 + 21 + 30 cm ²
=> 100 + 97.2 cm²
=> 197.2 cm² <em><u>Ans.</u></em>

5 can go into 20 numbers between 1-100 and 8 can go into 12 numbers between 1-100
Answer:
a. 24
b. 2
c. 0.0833 = 8.33%
Step-by-step explanation:
a.
The first "slot" of person to arrive has 4 possibilities, then the second "slot" will have 3 possibilities, as one has already arrived, then the third "slot" has 2 possibilities, and the fourth "slot" has just 1 possibility.
So, multiplying all these combinations, we have 4*3*2*1 = 24 possible ways they can arrive
b.
If the first and the last person are already "locked", we just have possibilities for the second and third person. The second will have 2 possibilities (Sergio or Tyrone), and the third will have only 1 (the person that wasn't the second between Sergio and Tyrone). So, the number of possibilities is 2*1 = 2
c.
If we have 2 cases where Dawn is first and Jim is last, from a total of 24 possible cases, the probability is 2/24 = 1/12 = 0.0833 = 8.33%
