Find the coordinates of p so that p partitions the segment ab in the ratio 1: 1 is a(-4,15) and b(10,11)

The coordinates of point P are (3 , 13)

Step-by-step explanation:

* Lets explain how to solve the problem

- Point P divides the segment AB in the ratio 1 : 1

- The ratio 1 : 1 means divide the segment into two equal parts

- Then P is the mid-point of segment AB

- If (x , y) are the coordinates of the mid-point of a segments whose

 endpoints are (x1 , y1) and (x2 , y2) then;

∵ The coordinates of point A is (-4 , 15)

∵ The coordinates of point B is 10 , 11)

- Let point A is (x1 , y1) , point B is (x2 , y2) and point P is (x , y)

∵ x1 = -4 , x2 = 10 and y1 = 15 , y2 = 11

∴

∴

∴ The coordinates of point P are (3 , 13)

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:

the answer is 8.64
