Answer:
Here:
Step-by-step explanation:
You choose 2,4,6,8,10 as your solution points, or in other words the numbers you with substitute in for x.
The equation is:
y= 1/2x+1
So what we would do is take one number from the list above (2,4,6,8.10) and put it in for are.
So, Thats how you do it, I attached a completed version of your paper below!
Answer:
60 times will they ring together at the same second in one hour excluding the one at the end.
Step-by-step explanation:
Given : Five bells begin to ring together and they ring at intervals of 3, 6, 10, 12 and 15 seconds, respectively.
To find : How many times will they ring together at the same second in one hour excluding the one at the end?
Solution :
First we find the LCM of 3, 6, 10, 12 and 15.
2 | 3 6 10 12 15
2 | 3 3 5 6 15
3 | 3 3 5 3 15
5 | 1 1 5 1 5
| 1 1 1 1 1
So, the bells will ring together after every 60 seconds i.e. 1 minutes.
i.e. in 1 minute they rand together 1 time.
We know, 1 hour = 60 minutes
So, in 60 minute they rang together 60 times.
Therefore, 60 times will they ring together at the same second in one hour excluding the one at the end.
Remember, the volume formula of a sphere is 
.
Set that equation equal to whatever volume they give you and solve for r.
= 
Now solve for r! I know you can do this. If you need help, just comment.
