The circumference of a circle=2\pir
We know that diameter is double the radius, and therefore can be written as d=2r
Circumference of a circle in terms of diameter is C=\pid
The 2r cancels out

Answer:

Explanation below.

Step-by-step explanation:

1. a. \sqrt{x} =12

  b. \sqrt{x} ^{2}=12^{2}

  c. x=144

2. a. \sqrt{x^{2} } =\sqrt{196}

   b. x= 14

3.  

\sqrt{x} -4 +4= 8+4\\\sqrt{x} =12\\x= 3.46410161514  \\or  \\2\sqrt{3}

4.

2(x^{2} +3)=398\\x^{2} +3= 199\\x^{2} =196\\x=14

The locations, given in polar coordinates, for two ships are (8 mi, 63º) and (8 mi, 123º). Find the distance between the two shi
Anna35 [415]
We know that

The arrangement forms an isosceles triangle with equal legs of 8 miles.
The angle between the legs is equal to

123-63=60°

 Therefore, the other two angles are
Angles = (180-60)/2 = 120/2 = 60°
It can, therefore, be noted that all angles are equal and thus the resulting triangle is actually an equilateral triangle and thus all the sides are equal.

Hence
the answer is
the distance between the two ships is 8 miles apart

alternative Method
Applying the law of cosines
<span>c²=a²+b²-2*a*b*cos C
</span>where
a=8 miles
b=8 miles
C is the angle between the legs-------> 123-63------> 60 degrees
c is the distance between the two ships
so
c²=8²+8²-2*8*8*cos 60------> c²=64-------> c=√64------> c=8 miles

A group of 72 children completed a survey on what kind of sport they like. The choices were: Chess, Swimming, and Football. Ever
Svetach [21]

Answer:

19/72

Step-by-step explanation:

To calculate the probability that a randomly-chosen child from this group likes either Chess or Swimming but not Football?

We already know the number that liked chess only which is 10, we have to solve for those that liked swimming only which is

8+7+16+x = 40

x which represent swimming only is

40-31 = 9

Thus probability = 10/72 + 9/72 = 19/72
