Answer:
The second one n - 10 =30
Step-by-step explanation:
n - 10 = 30 so she left 10 at home and brings 30 to school so you add 10 to both side of the equation and the one side just has N because the ten's cancels out and you add 10 to 30 which gives you 40 so the final answer is n = 40
What? Do you need help? I’d this a problem you need answered
The volume of air surrounding the cone and inside the cylinder will be the difference of the volume of cylinder and the cone.
So,
Volume of air = Volume of cylinder - Volume of cone
Thus, the volume of the air surrounding the cone and inside the cylinder will be 1055.04 cubic centimeter
Answer:
3x(x^2-4x+9)
Step-by-step explanation:
That's a question about percentage.
Let's imagine that we want to know how much is 90% of 200. To do this calculation, we should multiply 200 by 90 and then divide the result by 100. We do that because 90% is the same thing that . So, 90% of 200 is equal to:
Now, imagine that you would like to know how much is 100% of 999. First, we multiply 999 by 100 and divide the result by 999. So, 100% of a number is equal to itself. That's a very important information, because it's possible to understand this:
- If the percentage is less than 100%, the result is less than original number.
- If the percentage is equal to 100%, the result is equal to the original number.
- If the percentage is greater than 100%, the result is greater than original number.
Now, we can solve our problem! \o/
The options that the percentage is less than 100% are: 35% of 300, 62% of 182 and 89% of 525. Therefore, their answers will be less than the original number.
And, the option that the percentage is greater than 100% are: 250% of 18, 300% of 250 and 120% of 72. So, their answers will be greater than the original number.

I hope I've helped. ^^
