100 POINTS PLUS BRAINLIEST FOR CORRECT ANSWER! Sam wants to take his phone and his Nintendo Switch with him on his upcoming road

trip. His parents tell him they will be leaving in a half-hour and Sam realizes he forgot to charge both of the devices. He hurries to plug in each device to get as much battery life as possible before they leave. When he plugged in his phone it only had a 5% battery life and his Nintendo Switch had 20%. He periodically checked back to see the progress of each device and kept notes of their progress. Use the given information above and Sam’s notes below to find out how much battery life each device will have when it is time to leave. Also, if the device will not be fully charged how much extra time should Sam ask his parents to delay their departure time by?
Sam’s Notes: After 6 minutes his phone had 20% and after 9 minutes it had 27.5%. After 10 minutes his Nintendo Switch had 32% and after 15 minutes it had 38%.

$ 65 is marked up to $70.20
olganol [36]
You can work out the difference between the numbers by taking the smaller one away from the larger one:
70.20 - 65 = 5.20

Then you can divide the difference (5.20) by the original number (65) to get how many percent it is of 65 in decimal form:
5.20/65 = 0.08

Then you can times it by 100, to get the percentage:
0.08 * 100 = 8%

This means there was a 8% price increase in $65 to get to $70.20

Hope this helps! :)

To determine whether a graph of a relation is also a function, Shayla declares that the y-axis is a vertical line and counts the
Mars2501 [29]

Answer:

No.

Step-by-step explanation:

The function is any equivalence relation in which there is only one output for every input. This means that the domain must be exhausted in order to gain all the elements of the range and each element of domain gets mapped to only one of the elements of the range. Vertical line test is used to determine whether a graph is a function or not. This test requires that vertical lines parallel to y-axis and including y-axis be drawn on the graph to see that each vertical line intersects the graph only once. This must be true for all the elements of the domain. Therefore, vertical line test requires to draw numerous vertical lines other than the y-axis since the definition of the function requires that. In short, mathematically, there will be a need for infinite number of vertical lines to perform the test. Therefore, Shayla is not applying the vertical line test correctly!!!
