Answer: The required percentage is 75% of print area filled with advertisement.
Step-by-step explanation:
Since we have given that
Part of the print area of the newspaper carried new = 
Rest was filled with advertisements = 
So, Percentage of the print area was filled with advertisement is given by
Hence, the required percentage is 75% of print area filled with advertisement.
450 divides by 10 to receive a product of 45
Answer:
D) Only (-1,9) is a solution.
Step-by-step explanation:
x+y =8
x^2 + y = 10
Lets check the first point (-1,9)
Put in x =-1 y =9
x+y =8
-1+9 = 8
8 =8
This works
x^2 + y = 10
(-1)^2 +9 =10
1+9 = 10
10 = 10
This works
Lets check the second point (-2,6)
Put in x =-2 y =6
x+y =8
-2+6 = 8
4=8
This does not work
We can stop now. (-2,6) cannot be a solution
Answer:
1/15600
Step-by-step explanation:
This is a great example of what people call the Multiplication Principle.
First, find out how many ways the cards can be chosen. You're picking 3 cards from a set of 26 without replacement. The number of choices for the first card is 26, for the second card 25, for the third card 24. The cards can be chosen in 26 x 25 x 24 = 15600 ways.
Now for the specific choice "A B C" the number of ways that can happen is
1 x 1 x 1 (one choice for the first card, 1 for the 2nd, 1 for the 3rd)
The probability is 1/15600
