Answer:
Step-by-step explanation:
Distinct ways in which Barry can arrange the wooden shaped blocks is calculated from the permutation expression
4 permutation 3 =
P(n,r)=P(4,3) =4! ÷ (4−3)! = 24
Billie's distinct ways of seeing the arrangement would be 4 permutation 2
P(n,r)=P(4,2) =4! ÷ (4−2)! = 12

Step-by-step explanation:
Answer:
3 nights
Step-by-step explanation:
Set up an equation that represents the problem:
y = 1.25x + 3.95
Where y is the total cost and x is the number of additional nights you rent the movie
Substitute:
7.70 = 1.25x + 3.95
Subtract 3.95 on both sides:
7.70 = 1.25x + 3.95
-3.95 -3.95
3.75 = 1.25x
Divide by 1.25 on both sides:
3.75 = 1.25x
/1.25 /1.25
3 = x
Therefore, you kept the movie for 3 additional nights.
