Answer:
A
Step-by-step explanation:
Parallel lines are two lines that are next to each other and extend infinitely in both directions without every meeting.
The expression for the number of segments drawn out of the n number of points in the circle is,
n² / 2 - n / 2
Substituting directly to the expression the number of points, n, which is equal to 8,
8² / 2 - 8 / 2 = 28
Thus, there are 28 segments that can be drawn from the points.
Answer:
18
Step-by-step explanation:
Let x represent smallest number and y represent second number.
We have been given that the biggest among three numbers is 2.4 larger than the smallest one. So biggest number would be
.
We are also told that 15 times the smallest one is equal to 12 times the second and 10 times the third. We can represent this information in equations as:
![15x=12y...(1)](https://tex.z-dn.net/?f=15x%3D12y...%281%29)
![15x=10(x+2.4)...(2)](https://tex.z-dn.net/?f=15x%3D10%28x%2B2.4%29...%282%29)
Upon solving 2nd equation, we will get:
![15x=10x+24](https://tex.z-dn.net/?f=15x%3D10x%2B24)
![15x-10x=10x-10x+24](https://tex.z-dn.net/?f=15x-10x%3D10x-10x%2B24)
![5x=24](https://tex.z-dn.net/?f=5x%3D24)
![x=\frac{24}{5}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B24%7D%7B5%7D)
![x=4.8](https://tex.z-dn.net/?f=x%3D4.8)
Therefore, the smallest number is 4.8.
The biggest number would be
.
Upon substituting
in equation (1), we will get:
![15(4.8)=12y](https://tex.z-dn.net/?f=15%284.8%29%3D12y)
![72=12y](https://tex.z-dn.net/?f=72%3D12y)
![y=\frac{72}{12}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B72%7D%7B12%7D)
![y=6](https://tex.z-dn.net/?f=y%3D6)
Therefore, 2nd number would be 6.
Let us find sum of all numbers as:
![4.8+6+7.2=18](https://tex.z-dn.net/?f=4.8%2B6%2B7.2%3D18)
Therefore, the sum of all 3 numbers would be 18.
