Triangle PQR is shown below. Its original lengths are multiplied by 2.5. What are the new side lengths of P’Q’R’? 17, 8, 15

17 will change to 42.5

8 will change into 20

and

15 will change into 37.5

Step-by-step explanation:

Multiply them all by 2.5

A 37.5 cm x 20 cm x 42.5 cm

Step-by-step explanation:

Its  37.5 cm x 20 cm x 42.5 cm

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:

it could be 1,3 and more others to create a cylinder.
