Answer:
Monica spent 0.55 hours listening to Brahms.
Step-by-step explanation:
We are given the following in the question:
Amount of time spent listening to tapes of Beethoven and Brahms =
![=\dfrac{3}{4}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B3%7D%7B4%7D)
Amount of time spent listening to Beethoven =
![=\dfrac{1}{5}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B5%7D)
Total time spent listening to Brahms =
Amount of time spent listening to tapes of Beethoven and Brahms - Amount of time spent listening to Beethoven
![=\dfrac{3}{4}-\dfrac{1}{5}\\\\=\dfrac{15-4}{20}\\\\=\dfrac{11}{20}\text{ Hours}\\\\=0.55\text{ Hours}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B3%7D%7B4%7D-%5Cdfrac%7B1%7D%7B5%7D%5C%5C%5C%5C%3D%5Cdfrac%7B15-4%7D%7B20%7D%5C%5C%5C%5C%3D%5Cdfrac%7B11%7D%7B20%7D%5Ctext%7B%20Hours%7D%5C%5C%5C%5C%3D0.55%5Ctext%7B%20Hours%7D)
Thus, Monica spent
listening to Brahms.
Answer:A vertex (or node) of a graph is one of the objects that are connected together. The connections between the vertices are called edges or links. A graph with 10 vertices (or nodes) and 11 edges (links).
Step-by-step explanation: (The vertex formula is derived from the completing-the-square process, just as is the Quadratic Formula. In each case, memorization is probably simpler than completing the square.) For a given quadratic y = ax2 + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k.
Answer: D
(0,-4) (12,6)
slope= 10/12
slope== 5/6
y=5/6x+b
-4=0+b
b=-4
the equation of the line is
y=5/6x-4
