50% of teachers prefer to go to the aquarium.
Step-by-step explanation:
The sum of the complex number 12 – 5i and –3 + 4i is 9 - i
<h3>How to sum complex number?</h3>
The sum of 12 – 5i and –3 + 4i can be done as follows:
Therefore,
12 - 5I + (-3 + 4i)
12 - 5i - 3 + 4i
Hence,
combine like terms
12 - 3 - 5i + 4i
Finally,
9 - i

First calculate volume of the cylindrical container: Pi * R2 * H; where Pi is 22/7 or 3.147, R is the radius and H is the height of the container.
Vol of the cylindrical container: 3.147 * (3.25/2) * (3.25/2)* 5 = 41.55 inch 3
Volume of the shaker using the above principle:
3.147 * (1/2) * (1/2) * 1.5 = 1.18 inch 3
Number of times it can fill the salt shaker will be the ratio of the volumes:
= Volume of the cylindrical container divided by the volume of the shaker = 41.55 divided by 1.18
Answer is 35 times if rounded in absolute number.
We want to simplify this as much as possible. 11/110=1/10 since 110=11*10. Therefore, the answer is 0.1
Your answer is 9.
Since you have
2(2)^2 you get 2(4) which is 8.
Then you have -3(2) which is -6.
Lastly you have the 7.
When you add it up you get.
9
