Answer:

Step-by-step explanation:
Given : Vertices of Triangle
,
and 
To find : Centroid of a triangle
The centroid of a triangle is the point of intersection of the three medians of the triangle.
The formula to calculate the centroid of a triangle is:

Where,
are the coordinates of the centroid
Substituting the values in the formula gives us:



Therefore, 
Answer:
7 -if rounded to the nearest tenth would be 10
Step-by-step explanation:
The median is the number in the middle so
6-6-7-7-10-12-14
There are 7 numbers here so the middle number is 4 because there are 3 numbers before 4 and 3 numbers after 3 to get to 7 (that’s really hard to explain sorry but it’s a simple concept) my trick is to write it down then use two fingers to point at the first and last number and keep doing that moving in til I get to the middle number, which is 7. :)
The length of the line is 21.
$820.02
Step-by-step explanation:
Since the Taylor family had cash receipts of $876.16 and their excess of cash receipts above cash payments was $56.14.
The total cash payments for the month will be calculated as:
= $876.16 - $56.14
= $820.02
