Coordinates of centroid of a triangle with vertices of (0,1) (2,6) (7,2)

The centroid is located at (3,3)

Step-by-step explanation:

Centroid Of A Triangle

The centroid of a triangle is the point where its three medians intersect. It is also the center of gravity of the triangle. The medians are lines that go from each vertex to the midpoint of the opposite side.

Given A(ax,by), B(bx,by), C(cx,cy) the points of the vertices, then the coordinates of the centroid are

The vertices are  (0,1) (2,6) (7,2), thus

The centroid is located at (3,3)

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
