Answer:
5
Step-by-step explanation:
To obtain the total score for all the 20 students, we multiply the average score by the number hence
Total score for all 20 is 81*20=1620
Similarly, for the 19 students, the sum of their total score equals the product of the average and number of students hence
Total score for 19 readable is 19*85=1615
The difference between these two total scores ie for 20 and 19 students equals to the value of unreadable score. Therefore,
Difference=1620-1615=5
Therefore, the value of unreadable score is 5
34-6=28
The correct answer is 28
Answer:
∠ C = 133°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , that is
∠ A + ∠ B + ∠ C = 180° ( substitute A + B = 47° )
47° + ∠ C = 180° ( subtract 47° from both sides )
∠ C = 133°
Answer:
305 and 793
Step-by-step explanation:
LCM * HCF = product
3965 * 61 = 241,865 = 5*13*61*61
HCF = 61 so
61*5 = 305
61 * 13 = 793
