Find the slopes of the three sides.
slope of AB = 2/(-5) = -2/5
slope of AC = -2/(-4) = 1/2
slope of BC = -4/1 = -4
No two slopes have a product of -1, so no two sides are perpendicular.
Therefore, the triangle is not a right triangle.
It can be cut into nine different pieces that size with no rope left over
Answer:
2.27%
Step-by-step explanation:
Lets start by making the names letters, J C and A respectively.
The total is 44 dollars. J paid 34%, which would be 14.96. He pays a total of $15. C paid 50%, which is 22 dollars. A pays 17%, which would be 7.48. She pays a total of $8.
15 + 8 + 22 = $45, meaning they paid an extra 1 dollar. One dollar is 1/44th of $44, or 2.27%.
Note: 2.27% is 2.272727272727 repeated, do what you will with that information, every site is different.
Step-by-step explanation:
Use the FOIL method
w × 6w =
w × 2z = 2wz
-7z × 6w = -42wz
-7z × 2z =
this simplified equals
first term: 6w^2
second term: -40wz
third term: -14z^2
Answer: The probability that they will visit the cities in alphabetical order is
Step-by-step explanation:
Since we have given that
Number of different cities a tourist in France wants to visit = 7
According to question, if the route is randomly selected ,
Probability that they will visit the cities in alphabetical order is given by
so, the probability that they will visit the cities in alphabetical order is
