Answer:
1716 ways
Step-by-step explanation:
Given that :
Number of entrants = 13
The number of ways of attaining first, second and third position :
The number of ways of attaining first ; only 1 person can be first ;
Using permutation :
nPr = n! ÷(n-r)!
13P1 = 13! ÷ 12! = 13
Second position :
We have 12 entrants left :
nPr = n! ÷(n-r)!
12P1 = 12! ÷ 11! = 12
Third position :
We have 11 entrants left :
nPr = n! ÷(n-r)!
11P1 = 11! ÷ 10! = 11
Hence, Number of ways = (13 * 12 * 11) = 1716 ways
10 divided by 2 =5 because it ends at 10 and goes back by 2 and there are 5 loops
Step-by-step explanation:
y is 130° too because it's an alternative angle love
Answer:
11- 64 degrees
12- 66 degrees
13- 89 degrees
14- 99 degrees
Step-by-step explanation:
11. 100 + 130 + 66 = 296
360 - 296 = <u>64</u>
12. 103 + 133 + 58 = 294
360 - 294 = <u>66</u>
13. 154 + 88 + 29 = 271
360 - 271 = <u>89</u>
14. 101 + 92 + 68 = 261
360 - 261 = <u>99</u>
hope this helps :)
Volume = Area * height
= width * length * height
= 8 * 4 * 7
= 224 cm^3
