answer:

16/3 of water jacoby has used for 8 cups of flour.

step-by-step explanation:

let us assume that jacoby   used x cup of water. and from given information

we know that for every 2 cup of water jacoby used 3 cup of flour which will gives the information

for every 1 cup of flour he will use 2/3 of water

now, we need to calculate the number of cups of water that has been used for 8 cups of flour

if for 1 cup of flour its is 2/3 of water then

for 8 cup of flour he will use 8*2/3   of water which is 16/3 of water.

not sure but it may be b, as i said i'm not sure.

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
