Answer:
AC = 12.4 km (nearest tenth)
Step-by-step explanation:
AC can be calculated by using Pythagorean Theorem.
Thus:
AC² = AB² + BC²
Plug in the values
AC² = 8² + 9.5²
AC + √{154.25)
AC = 12.4 km (nearest tenth)
Answer:
40320
Step-by-step explanation:
There are 8 different people we could assign to the first task. Now there are 7 tasks and 7 people left. There are 7 different people we could assign to the next task. And so on
8 *7*6*5*4*3*2*1
8!

Answer:
The number N = 26
Step-by-step explanation:
The statement is :
Six less than twice a number is that of that number plus 20
The statement now written in digits as
Let the number be N
So, 2 N - 6 = N + 20
Or, 2 N - N = 20 + 6
Or, N = 26
Hence the number N is 26 Answer
