Answer:
Solution : 3.6 miles
Step-by-step explanation:
The first step in solving this problem is to convert 15' to degrees --- (1) . 15' is represented as 15 minutes, so to convert to degrees we have 15 / 60 = 0.25°. Adding 20 + 15' we should get 20 + 0.25 = 20.25 (degrees).
Now remember that on the right side we have the football field, 62° 30'. Let's convert that 30' into degrees --- (2). 30 / 60 = 0.5, and 62 + 0.5 = 62.5.
Using both this information we can calculate the angle from the balloon to the horizontal. That would be 180 - 20.25 - 62.5 = 97.25°. Therefore the distance from the balloon to the soccer fields would be as follows,
distance / sin(62.5) = 4 / sin(97.25)
Let distance = x ...
x / sin(62.5) = 4 / sin(97.25),
x / 0.88701083317 = 4 / 0.99200494968,
x * 0.99200494968 = 4 * 0.88701083317,
x * 0.99200494968 = 3.548,
x = ( About ) 3.5766 miles
Given the options the distance from the balloon to the soccer fields would be 3.6 miles.
a. 0.000000861
b. 0.0000000861
c. 8,610,000
d. 861,000,000
To complete the square of the equation, the number to add to both sides is: 9.
To complete the square of an equation, the number to add to both sides should be determined by squaring half of the term that has a variable without an exponent.
Given the equation, x² - 6x = 5:
To complete the square, square half of -6
1/2 of -6 = -3
Square of -3 = 9
Therefore, to complete the square of the equation, the number to add to both sides is: 9.

Answer:
2 2/5 miles per hour
Step-by-step explanation:
We want to find the miles per hour
Changing the miles to an improper fraction
1 1/5 = ( 5*1+1)/5 = 6/5 miles
6/5 miles
Divide by the number of hours 1/2
6/5 ÷ 1/2
Copy dot flip
6/5 * 2/1
12/5
Change back to a mixed number
2 2/5 miles per hour
