Acircle has a radius of 12.6cm what is the exact length of an arc formed by a central angle measuring 120

26.13 cm

Step-by-step explanation:

Arc length (A) = (Θ/ 360) x (2 x π x r)

120/360=0.33

2 x π x 12.6=79.17

0.33 x 79.17=26.13 cm

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

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:
