  AFH, BFG, CDG, EFG

Step-by-step explanation:

For this answer, we assume the edges of the cube are ...

  AB, AC, AE, BF, BH, CD, CG, DH, EF, EG, FH, GH

The right triangles will include at least one edge and any of the other 6 points. The right triangles are ...

  AFH, BFG, CDG, EFG . . . . . . . an edge is highlighted

question

what is the value of the third quartile of the data set represented by this box plot? a. 19 b. 21 c. 26 d. 29

answer

c

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
