Answer:
⅕
Step-by-step explanation:
Given that points X, Y, and Z are collinear, and X is said to partition segment XZ in the ratio XY to XZ = 1:5, it means that segment XY = ⅕ of XZ. That is XY/XZ = ⅕
See attachment below to understand how point Y divides segment XZ.
Therefore, the k value Brianna would use when solving the problem should be the fraction, ⅕.
k value = XY/XZ = 1/5
Answer:
12.75
Step-by-step explanation:
To get to 20 minutes from 2 minutes you multiply by 10, do the same to the 30 problems to get 300. The answer is 300 problems in 20 minutes.
It's not possible, because the sum of the lenghts of every two sides of a triangle has to be greater than the length of the third one. It this case that condition isn't met:
