Answer: See below
Step-by-step explanation:
This relates to the usage of water displacement.
- Have the 10 ml of water ready in a measuring flask (or any container that has a scale)
- Put the marble into the water
- Observe how much did the water rise
- Subtract the current water level by the original 10 ml
- The final answer would be the volume.
------------------------------------------------------------------------
EXTRA (Only for advanced purposes, if you do not understand, it is totally fine)
Refer to the attachment below to finish the question.
Assuming the water levels are integer,
- The original water level is <u>13.33 ml</u>
- After the rock is put in, the water level is raised to <u>30 ml</u>
Then, we do the fourth step which is subtraction
Hope this helps!! :)

Its probably a division question. 250 divided by nine which is 27.7 which rounds to 28.
(1+6i)—(7+3i)
1+6i—7–3i
1. 1–7 = —6
2. 6i—3i=3i
So
-6+3i
sorry if im wring but I calculate 4 is correct answer
