What are the coordinates of the centroid of a triangle with vertices at D (0, 0), E (–8, 0), and F (–7, – 6)? ANSWERS: A) (–5, –2) B) (2, 5) C) (–2, –5) D) (5, 2)

A) ( -5 , -2)

Centro-id of  a triangle  = ( -5 , -2)

Step-by-step explanation:

Given  the  vertices at D (0, 0), E (–8, 0), and F (–7, – 6)

Centro-id of triangle

                     =  

                    =

                    =

                    = ( -5 , -2)

Final answer:-

Centro-id of  a triangle  = ( -5 , -2)

the anwser is d) 75°

step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
