The cost of 8 adults tickets to a movie is $66. What is the cost of one adult ticket?
Papessa [141]
If you want to find the cost per adult if 8 of them buy tickets for a total of $66, you would divide the total cost by the number of tickets bought. So, $66 divided by 8 would equal to $8.25 per ticket.

How many circles of radius 1 can fit into circle of radius 500?
Gekata [30.6K]

using 3.14 for Pi , since you didn't say what value to use

area = PI x r^2

 Area of larger circle = 3.14 x 500^2 = 785,000 square units

area of smaller circles = 3.14 x 1^2 = 3.14 square units


785,000/ 3.14 = 250,000 small circles can fit into larger one

Anit [1.1K]

Answer:

41x² - 27x + 27

Step-by-step explanation:

Perimeter of Rectangle:

= 2(20x²-12x+4) + 2(5x²-5x+15)

= 40x²-24x+8 + 10x²-10x+30

= 50x²-34x+38

Perimeter of Triangle:

= 6x²+6x+3x+3+3x²-2x+8

= 9x²+7x+11

Difference:

(50x²-9x²)+(-34x+7x)+(38-11)

= 41x² - 27x + 27
