25.13 cm is the circumference of the circle
Answer:
19.44
Step-by-step explanation:
We have the following information:
3 red balls, 5 green balls, and 1 yellow ball
In total there are 3 + 5 + 1 = 9 balls.
We calculate the probability of each:
Network: 3/9
Green: 5/9
Yellow: 1/9
Each one corresponds a price in profit or losses:
Network: 4
Green: -3
Yellow: 10
So in total it would be the sum of the multiplication of the probability and the price and then multiply everything by 25:
(4 * 3/9 + -3 * 5/9 + 10 * 1/9) * 25 = (0.777) * 25
= 19.44

Step-by-step explanation:
BDC=95
3x-52=2x+2 (v.o.a)
3x-2x=2+52
x=54
Answer:
A= 8
B= -5
C= -14
Step-by-step explanation:
Area of Rectangle = length * width
Area of the shaded Rectangle:
Area = l * w
Area= (4x + 1) (3x - 5)
Open the brackets
A= 12x^2 - 20x + 3x - 5
A = 12x^2 - 17x - 5
Area of the Unshaded:
The Unshaded portion is a square. Hence, it's area = l^ 2
Area = (2x - 3) ( 2x - 3)
A= 4x^2 - 6x - 6x + 9
A= 4x^2 - 12x + 9
To get the exact shaded portion
A(Shaded) = (12x^2 - 17x - 5) - ( 4x^2 - 12x + 9)
Area = 8x^2 - 5x - 14
A= 8
B= -5
C= -14
