Can i have an explanation for why this is d please

(someone else told me it was d)

Im quite ceratin it's B.

Step-by-step explanation:

Divide each of those values and you get 5 except for B.

a) 4/0.8=5

b) 55/10=5.5

c) 20/4=5

d) 50/10=5

Notice how it is asking you for a relationship, not appearance.

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
