Imagine you identify two elementary schools for research into the effects of density and crowding. School A has an average class size of 45, and children must go to lunch and recess in shifts because the cafeteria and the playground cannot accommodate all of them at once. In School B, the average class size is 20, there's extra room in the cafeteria when all the children are there, and all the kids have recess together on a large playground. Before beginning your research, what do you already know about these schools

step-by-step explanation:

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.

plzz mark brainlest last one got deleted. cause i didn't explain it but i did but i understand what the mod meant

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
