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!! :)

Answer:
80°
Step-by-step explanation:
The total of angle 2 and the one marked 30° is an angle corresponding (hence, equal) to the one marked 110°.
∠2 +30° = 110°
∠2 = 80°
hope this help Answer:( x - 3i√2)(x + 3i√2)
solve x² + 18 = 0
x² = - 18 ⇒ x = ±√- 18 = ±3i√2
factors are ( x - (3i√2))(x - (-3i√2))
x² + 18 = (x - 3i√2)(x + 3i√2
