Answer:
500 people
Step-by-step explanation:
To find how many people said they liked golf, find 5% of 10,000, by multiplying 10,000 by 0.05:
10,000(0.05)
= 500
So, 500 people said they liked playing golf
What we need to do here is create an equation to solve.
the total cost of the trip was £591
this means that the amount for children + the amount for adults = 591
entrance fee was £12.35 for each adult and £8.75 for each child.
this means that our equation now is 12.35A + 8.75C = 591
the cost of hiring the coach was £118
this means we need to add this into our equation:
118 + 12.35A + 8.75C = 591
But we know how many children there are, 47. So we can plug in 47 for C then solve
118 + 12.35A + 8.75C = 591
118 + 12.35A + 8.75(47) = 591
118 + 12.35A + 411.25 = 591
12.35A = 591 - 411.25 - 118
12.35A = 61.75
A = 5
There were 5 adults in the group
The equation of the segments perpendicular bisector is; y = -¹/₂x + 2
<h3>How to find the equation of the perpendicular bisector?</h3>
i) Since it is a perpendicular bisector, hence point M is the midpoint. Thus;
Midpoint (AB) = [(x₁ + x₂)/2], [(y₁ + y₂)/2] = (x_m, y_m)
Slope AB will be;
m₁ = ((x₁ - x₂)/(y₁ - y₂))
Slope of perpendicular bisector is;
m₂ = -1/m₁
Equation of perpendicular bisector is;
(y - y_m) = m₂(x - x_m)
ii) Midpoint (AB) = [(-2 + 6)/2], [(3 - 1)/2] = (2, 1)
Slope AB will be;
m₁ = ((6 + 2)/(-1 - 3)) = -2
m₂ = -1/-2 = 1/2
Equation of perpendicular bisector is;
(y - 1) = -¹/₂(x - 2)
y - 1 = -¹/₂x + 1
y = -¹/₂x + 2
