area = pi x r^2
615.75 = 3.14 x r^2
r^2 = 615.75/3.14 =196.0987 round to 196.1
r = sqrt(196.1) = 14.00357 round to 14
radius = 14 kilometers
Answer:
The length of one leg of the triangle is 22 units
Step-by-step explanation:
The complete question in the attached figure
Let
x ----> the length of one leg of the triangle
we know that
In the right isosceles triangle of the figure
The cosine of angle of 45 degrees is equal to the adjacent side to angle of 45 degrees divided by the hypotenuse
---> equation A
----> equation B
equate equation A and equation B and solve for x
therefore
The length of one leg of the triangle is 22 units
The percent data between 6.0 and 6.9 would
be 13.59%. Here’s the complete solution for this specific problem.
<span>z = (X - Mean)/SD </span><span>
<span>z1 = (6 - 5.1)/09 = + 1 </span>
<span>z2 = (6.9 - 5.1)/09 = + 2 </span>
<span>Required Percent = P(6 < X < 6.9)*100 </span>
<span>= P(1 < z < 2)*100 </span>
<span>= [P(z < 2) - P(z < 1)]*100 </span>
<span>= [0.9772 - 0.8413]*100 </span>
<span>= 0.1359*100 </span>
<span>= 13.59%

2y + 2(y-2) = 5y - 3(y-10)
2y + 2y - 4 = 5y -3y +30
4y - 4 = 2y + 30
4y - 2y = 30 + 4
2y = 34
y = 34/2
y = 17
Answer:
NO. |-6| = 6 - a positive integer
Step-by-step explanation:
|a| = a for a ≥ 0
examples
|2| = 2, |0| = 0, |0.56| = 0.56
|a| = -a for a < 0
examples
|-2| = -(-2) = 2, |-100| = -(-100) = 100, |-0.25| = 0.25
Therefore your answer:
|-6| = 6 > 0
