Answer:
I think A is the answer
hope this helps
have a good day :)
Step-by-step explanation:
If I have eight numbers and i am tasked to decide which of the set of given numbers is the smallest comparing 2 numbers at a time, I will have 28 comparisons in all. Trying all combinations for the first number, you have 7. Trying all combinations for the second number nit including its comparison to the first number (because it will be redundant), you will have 6 comparisons an so on. Adding it all up, you have 7+6+5+4+3+2+1=28.
Answer:
0
Step-by-step explanation:
The slope of a horizontal line is 0.
/ is a positive slope
\ is a negative slope
A horizontal line has a slope of 0
A vertical line has an undefined slope.
You can verify this by using the slope formula
![m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D%20-x_%7B1%7D%20%7D)
m = ![\frac{-3 -(-3)}{-11-4}](https://tex.z-dn.net/?f=%5Cfrac%7B-3%20-%28-3%29%7D%7B-11-4%7D)
m = ![\frac{0}{-15}](https://tex.z-dn.net/?f=%5Cfrac%7B0%7D%7B-15%7D)
Answer:
The answer will be 6 I believe
The answer is C.) 4cm + 7cm + 8cm
This is because you don't have to do any converting from inches to centimeters or vice versa, which means that you can keep the same numbers and just add no problem! :)
I hope this helped! Have a great day! :P
