The absolute value of numbers is the distance it is from 0. More simply, you can just take away the negative sign (if there is one).
5 is 5 away from 0.
-6 is 6 away from 0.
2 is 2 away from 0.
-9 is 9 away from 0.
The picture in the attached figure
step 1find the area of a square
area of a square=b²
b in this problem is the diameter of a circle
b=2*9------> b=18 units²
area of a square=18²-----> 324 units²
step 2find the area of a circle
area of a circle=pi*r²
r=9 units
area of a circle=pi*9²------> 254.34 units²
step 3find <span>the probability that the dart hits a point in the circle
P=area of the circle/area of the square
P=254.34/324------> P=0.785-----> 78.5%
the answer is78.5%</span>
Answer:
2.4 inches per hour
Step-by-step explanation:
A total of 13.2 inches of snow fell during a snowstorm that lasted 5.5 hours and the same amount of snow fell each hour of the storm.
This means that there was a constant rate of snow fall.
To find how many inches of snow fell each hour, we divide the amount of snow fall by the amount of time that the snowstorm lasted.
That is:

R = 2.4 inches per hour
This means that 2.4 inches of snow fell each hour during the snowstorm.
I’m not sure about the wording of the question, but wouldn’t it be all real numbers?
The equation of the circle with center (h, k) and radius r is
.. (x -h)^2 +(y -k)^2 = r^2
1. selection D matches the specification of the circle
2. selection A matches the given equation
3. None of the offered selections matches
.. (x -3)^2 +(y -5)^2 = 74
4. selection A matches the requirements
