If N is first and L is last, then we just need to find all of the permutations for M, O, and P
with first letter M: MOP MPO
with first letter O: OPM OMP
with first letter P: PMO POM
Now, place the N in front and the L at the end of each permutation. There are 6 permutations in total:
NMOPL NMPOL
NOPML NOMPL
NPMOL NPOML
The three interior angles of any triangle add to 180 degress. Therefore,
180-(120 + 40) = the third angle.
So, 20 is the third angle
Answer:
I think the answer is 194.6 miles on the third day
Step-by-step explanation:
Answer: 144-4x=112 she missed 8 questions
Step-by-step explanation: Since there are 144 points in total and each question is worth four points you would subtract 4x with x being the number of questions missed from the total amount and set it equal to 112. Then you solve for x which gives you 8. Hope this helps. :)
