Answer:
Step-by-step explanation:
To solve this problem we are going to set Python as the language.
books = ["a", "b", "c", ... , "z"]
selection = list(3) #here we set a list of dimension 3 as 3 are supposed to be selected
for book in books: #here we parse into the books list
If book in selection: continue #in order to obtain different books, if the book #already in selection list, then we jump
selection.append(random.choice(books)) #if not, we add the book to #selection
print(selection)
Assuming the wire starts at x=0, the first point is (0,-4) since using y = 3x - 4 :
3(0) - 4 = -4
the two points are (0,4) and (-3,4)
since the y values are the same, the distance is the positive difference between the x values:
-3 - 0 = -3
then,
the distance is 3 meters
each meter costs $125, so multiply the cost by the amount of meters to find the total:
125 x 3 = 375
the total cost is $375
Area of rectangle = length*breadth
= 30*22
=660 yards2
hence answer is D.

Answer:
(72/17) hours
Step-by-step explanation:
Time Jackie would take alone , J = 8 hrs
Time Patricia would take alone , P = 9 hrs
Let the time they will take together be T
use the formula for shared unit rate
= +
= +
=
T = hours (or 4.24 hours)
