Let the number of holes of golf you can play be x before your money runs out. I assume both the costs of playing and the income should be equal.
Let your expenses be 25 + 0.50x
Let your income be
a = 18
n = x
d = -1
Sum of income =(a + L)*n/2; L = a + (n - 1)*d
sum of income = (a + a + (x - 1)*d )*x/2
Sum of income = (2a + (x- 1)*(-1) ) * x/2
Sum of income = (2*18 + (x -1 ) (-1) ) * x / 2
Sum of income = (36 - x + 1) * x / 2
Sum of income = (37 - x )* x / 2 Now the income has to equal the expenses.
25 + 0.5x = (37 - x)*x/2 Multiply both sides by 2 and remove the brackets.
50 + x = 37x - x^2 Bring the right side over to the left.
x^2 - 36x + 50 = 0
You need help from the quadratic formula
a = 1
b = -36
c = 50
This does not come to anything nice. I'm getting x = 34.6 holes or x = 1.44.
Answer:
The Required area of Δ is .
Step-by-step explanation:
Diagram of given scenario is shown below.
Given that,
, and °
To find : The area of Δ .
So, from the question
Area of triangle when two sides and one angle (between two known sides) are given , where is the given angle.
Substituting the given values in above to find area of Δ we get,
Therefore, The Required area of Δ is .
