The wheel covered 785 feet in one complete turn
<em><u>Solution:</u></em>
Given that, The first Ferris wheel was built in 1893 in Chicago
Diameter of wheel = 250 feet
<em><u>Let us find the radius of wheel</u></em>
Thus radius of wheel is 125 feet
We have to find the distance covered in one complete turn
The number of feet the wheel rotated in one turn is equal to its circumference
<em><u>The circumference of circle is given as:</u></em>
Where, "r" is the radius and 
is a constant equal to 3.14
<em><u>Substituting the values we get,</u></em>
Thus the wheel covered 785 feet in one complete turn
Cameron's current service charge of $0.95 per song, and the new service charge of $0.89 per song and $12 fee for joining, gives;
- Formula for finding the number of songs that makes the cost of both services the same is; 0.95•s = 12 + 0.89•s
- Computing the value of <em>s </em>that satisfies the above equation gives the number of songs at which the cost of both service is the same as 200 songs
- The interpretation is the the cost of either service is the same when 200 songs are downloaded
<h3>How can the equation that gives the required number of songs be found?</h3>
To Formulate
The charges for songs on the current music service is, C1 = 0.95•s
The charges for the new download service is, C2 = 12 + 0.89•s
Where the $12 is the joining fee
When the cost is the same for both service, we have;
C1 = C2
Which gives;
The equation to represent when the cost for both service is the same is therefore;
0.95•s = 12 + 0.89•s
Computing;
The number of songs that gives the same costs is therefore;
0.95•s = 12 + 0.89•s
12 = 0.95•s - 0.89•s = 0.06•s
s = 12 ÷ 0.06 = 200
- The number of songs at which the cost of each option will be the same is <em>s </em>= 200 songs
Interpreting the solution;
The interpretation is, the cost of songs downloaded on both service will be the same, when 200 songs are downloaded.

<h2>
Answer:</h2>
The number of possible arrangements is : 120
<h2>
Step-by-step explanation:</h2>
We know that in order to find the different arrangements which are possible we need to use the method of permutation.
The arrangement of a given word is calculated as the ratio of the factorial of number of letters to the product of factorial of numbers the number of times each letter is repeating.
The word is given to be:
ALASKA
There are a total of 6 letters in the given word
Out of which a letter "A" is repeating 3 times.
Hence, the number of arrangements possible are:
Answer:
(-19 , -7)
Step-by-step explanation:
y - x = 12
y + x = -25 we sum them to get
2y = -14 , y = -7
then we put -7 instead of y in any of the equations:
-7 - x = 12
-x = 19
x = -19,
finally (x , y) is (-19 , -7)
