Ethan and ava share a reward of $84 in a ratio of 4: 3. how much does ethan get?

Okay so first you would add 4 and 3 which altogether gives you 7. So that means Ethan is going to get 4/7 of the money and Ava is going to get 3/7 of the money. So to find 4/7 of the money you multiply 4/7 times 84 and you get $48. So ethan gets $48 .

The distance from point a to point c across the coordinate plane is aproxamatly 8.94 rounded to the nearest hundredth. you use a^2 + b^2 =c^2
