Answer:
Circle
Step-by-step explanation:
The definition of a circle is the set of points equidistant from a given point. Since all points are equidistant from this given point, the center, the radius is the same all throughout the circle; the only way to have all points equidistant is to travel around the center 360 degrees.
Set the equation up as a proportion, where x = the height of the tree in feet
27/x = 4.5/5
cross multiply
(4.5)(x) = (27)(5)
(4.5)(x) = 135
divide the entire equation by 4.5 to isolate x
135/4.5 = 30
x = 30
the tree is 30 ft tall

Answer:
$80
Step-by-step explanation:
Area of Mr Jones's yard = 40 * 65 square feet
= 2600 square feet
Mr. Jones was charged $52 for the yard.
Therefore cost per square feet = 52/2600 = $0.02 per square feet
Area of neighbor's yard = 50 * 80 = 4000 square feet
Hence the neighbor will be charged 0.02 * 4000 = $80
For the area corresponding to the yard of size 4000 square feet, he will have to pay $80 to the landscaping company.
