Answer:
1 - 1/2 = 1/2
Step-by-step explanation:
These numbers are the best estimation of the equation 7/8 - 6/11 because 7/8 is approximately 1 and 6/11 is approximately 1/2. If you subtract 1 from 1/2 you get 1/2.
I think x would equal 7 because when y=75 and x=25, x is one third of y so one third of 21 is 7
The angle the golfer went off line from the tee when they drove the ball
is
because the cosine rule has been applied to calculate the angle
From the question we are told that:
Distance of hole from tee 
Distance to the right 
Ball distance from hole 
Given that the three points form a triangle x,y,z respectively
Where



Using Cosine Rule

Therefore




In conclusion the angle the golfer went off line from the tee when they
drove the ball is mathematically deducted and give as

Answer:
(a) We will form an equation of line from the points given (6,10) and (2,15)
Using:
On substituting the values in the formula above we will get the required equation of line.


On simplification we will get:

(b) We need to tell at day 0 put x=0 in above equation:


Anika worked for 70 hours on the set up crew on the day the fair arrived at the fairgrounds day 0.
Now, we need to tell decrease per day which is equal to the slope of line
To find the slope compare the equation with general equation which is y=mx+c where m is slope
Here, in 
which is the decrease per day.
37.5 km is equal to 15 cm
