Answer:
B
Step-by-step explanation:
P(7,r) = 5040
(7 - r)! = 1!
7 -r = 1
7 = 1 + r
7 - 1 = r
r = 6
The answer are
1) gain
Because they asked the price of detergent per load
2) 0.38 per dollar
In this we have to divide 9.25/25
Anwser - c 0.70 I pretty sure
Answer:
Correct choice is C
Step-by-step explanation:
Let x be unknown number.
Three times a number x is
Three times a number is no less than negative six means that the number can be equal to -6, can be greater than -6, but cannot be less than -6.
Thus, the inequality that could be used to solve the problem is
Answer:
The sum of the degrees of all the vertices = 8
Step-by-step explanation:
A tree with 5 vertices. N = 5
The number of edges in any tree with N vertices will be N - 1
Using Euler's Sum of Degrees Theorem: Sum of the degrees of all the vertices equals twice the number of edges.
Hence 2(N-1) ==> 2(5 - 1) ==> 2(4) ==> 8
