Question 1 Jorge decided to buy a new fish tank. He's going to put marbles in the bottom of the tank.
Marbles have a radius of 0.25 inches, and Jorge plans to use 450 of them. The base of the fish
tank is a square with length of 15 inches. The height of the 30 inches. How many cubic inches
of water will it take to fill the fish tank after the marbles are in it?

do your own work and don"t cheat.

step-by-step explanation:

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
