I’m lost on this please help
1 answer:
We can Notice from the Figure that X is the Centroid of the Given Triangle.
We know that Centroid divides each Median in the Ratio 2 : 1
From the Figure : CH is one of the Median
Given the Length of CH is 33 ft
X divides the Median CH in the ratio 2 : 1
Let us Divide the Median CH into 3 Equal Parts
Length of Each Part of 3 Equal Parts =
⇒ Length of CX = 2 × 11 = 22 ft

Step-by-step explanation:
The diameter of a tire is 2.5 ft. a. Find the circumference of the tire. b. About how many times will the tire have to rotate to travel 1 mile?
Solution:
a) The circumference of a circle is the perimeter of the circle. The circumference of the circle is the distance around a circle, that is the arc length of the circle. The circumference of a circle is given by:
Circumference = 2π × radius; but diameter = 2 × radius. Hence:
Circumference = π * diameter.
Given that diameter of the tire = 2.5 ft:
Circumference of the tire = π * diameter = 2.5 * π = 7.85 ft
b) since the circumference of the tire is 7.85 ft, it means that 1 revolution of the tire covers a distance of 7.85 ft.
1 mile = 5280 ft
The number of rotation required to cover 1 mile (5280 ft) is:
number of rotation =
