Answer:
The average U.S. citizen throws away about 133.8 pounds of garbage a month.
Step-by-step explanation:
First take the total amount of trash thrown away in a year (1,606), and divide it by the number of months in a year (12).
1,606 / 12 = 133.833333
You would get 133.833333 and would round it to the nearest tenth and get 133.8.
Answer:
√10/2x
Step-by-step explanation:
Multiply by √6 on the top and bottom to rationalize the denominator.
(√15×√6)/(√6x×√6) = √90/6x = (√9×√10)/6x = 3√10/6x = √10/2x
X= 9.2
From the figure, the chord (12) is drawn with a line (from the center of the circle) perpendicular to it. It can be said that the chord 12 is bisected by the 7 long line from the center which gives us with 6 each of the two parts of the chord. Since they are forming (the 6 and 7) a right angled triangle, we can then use Pythagorean theorem to find X, which can be seen as the radius at the same time hypotenuse of the right angled triangle.
The circumference of a circle is 
Circumference = 
It says to leave in terms of pi which means that we won't solve 
Thus the answer is .
Hope that helped!
