1. 動物
2. 乾炒牛河
3. 可能, 穿雨衣/厚衫
4. any objects with emissitivity, e = 1 ie Black body
5. no, just look at the 走地雞 you order
6. attract the bull / irritate it
7. whale is mammal
8. my time
9. no, just go down the deep blue sea and u will find red algae that absorb light at a lower frequency
(red band)
10. kill one of the kid or cut all 5 apples into six equal slices
11. cactus dont "DRINK" water, rather, it "ABSORB"
12. yes, as suggested in Biology 11
13. no, wood and carbon (石墨)
14. from condensation of moisture existing in the atmosphere
15. Divide 12 cans into 3 groups of 4 cans, call them A1, B1, and C1.
weigh either two groups to eliminate two groups;
then divide the remaining 4 cans into 2 groups of 2
weigh both group to kick out 2 cans, the weigh one more time, done
16. 5 times
17. 60/4 = 15 camels
Let Single X, Double Y
X+Y = 15
X + 2Y = 23
Solve a 2D matrix using Row Reduce Euchelon Form,
rref(1,1,15;1,2,23) = (1,0,7;0,1,8)
Therefore, Single = 7, Double = 8
18. Yes, as suggested by most documentary
19. He is back at origin
Since North-West = 45deg, sqrt(100*100*2)=141
20. still working on this one
21. yes, prevent sand?
22. 444+44+4+4+4 = 500
23. wrong, off cause they can see during daytime (they just dont go out at daytime)
24. yes, since snakes dont have eyelips
25. Ming = X, Bro = Y
X + Y = 55; Y - X = 11
Solve 2D matrix rref(1,1,55;-1,1,11) = (1,0,22;0,1,33)
Ming = 22, Bro = 33
26. they need water as a media for sperm to swim through, or they both dormant
27. Two ways to approach this problem:
1) X(X+1)(X+2)(X+3)=3024, screw the math, using Matlab for answer....
n = 4
a = [1 6 11 6 0 3024 ]
M = zeros(n,n);
for i = [1:n-1]
M(i,1+i)=1;
end
for i = [1:n]
M(n,i) = -a(i);
end
[P,D] = eig(M);
D
Hopefully that works, havent tried yet, MatLab keeps crashing......
2) Brute Force approach with C programming in DevC++
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
int x = 1;
while ((x*(x+1)*(x+2)*(x+3))!=3024)
{x++;}
printf("The value of X is %x \n",x);
system("PAUSE");
return 0;
}
Miraculously X = 6
therefore, ages are 6, 7, 8, 9
28. Send this kid to schizoidal school
29. 8 four-people=boat; 3 nine-people-boat
30. 9, like a 井
31. contains something-tose rather than fructose, lactose, surcrose,glocose
32. O_o, no thoughts on this one
33. 小林本女子是也
34. 奇
35. 偶
36. No, according to Biology12
37. No, only increase by means of transpiration
38. No, at least the block solids are not poisonous gases
39. No, since intensity depends on what is in the way of the light reaching earth
(dust, rocks may block out some light, besides, it is a 3D space outside the sky)
