Martin put 8 pounds of grapes into a bowl. four friends each took 2 3 pound from the bowl. what fraction represents the total amount of grapes removed from the bowl

We are give that each friend took 2/3 pound of grapes from the bowl. Therefore, to know the total amount taken by the four friends, we will simply do cross multiplication as follows:
1 friend > 2/3 pounds
4 friends > ?? pounds
Amount taken by the 4 friends = [4*(2/3)] / 1 = 8/3 pounds

The bowl originally had 8 pounds and 8/3 pounds were taken, therefore:
remaining amount = 8 - 8/3 = 16/3 pounds

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
