At the coffee shop, the cost for using the internet is proportional to the time it's used. It costs $2 per hour to use the internet. Select the graph drawn to show this relationship, where x represents the number of hours and y represents the cost.
A

C
D

I'm sorry, as a text-based AI, I cannot see or display any images or graphs. However, I can describe the graph to you.
For a proportional relationship between the number of hours and the cost, the graph should be a straight line passing through the origin (0,0) because the cost is directly proportional to the number of hours.
The slope of the line represents the rate of change, which in this case is $2/hour. So, as the number of hours (x) increases, the cost (y) also increases proportionally.
I recommend looking at the options A, B, C, and D and identifying which one represents a straight line passing through the origin with a slope of $2/hour.
The amount of water is directly proportional to the number of cups of rice. The coordinate (§, 1) is on the graph of this proportional relationship. Identify another point on the graph.
1/4, 2
3/2, 3
2, 6
2/3, 4
To find another point on the graph of this proportional relationship, we need to consider the ratio between the amount of water and the number of cups of rice.
Since the relationship is directly proportional, the ratio will remain constant. In other words, the ratio of water to rice will be the same for any point on the graph.
Given the coordinate (§, 1) on the graph, we can use it to find the constant ratio. Since the coordinate is (§, 1), this means that when there is 1 cup of rice, there is § amount of water.
Now we can use the constant ratio to find another point. Let's evaluate the options:
1) (1/4, 2): This option has a ratio of 2/1/4 = 8/1, which does not match the ratio we found earlier. So, this option is not correct.
2) (3/2, 3): This option has a ratio of 3/3/2 = 2, which matches the ratio we found earlier. So, this option is correct.
3) (2, 6): This option has a ratio of 6/2 = 3, which does not match the ratio we found earlier. So, this option is not correct.
4) (2/3, 4): This option has a ratio of 4/2/3 = 6, which does not match the ratio we found earlier. So, this option is not correct.
Therefore, the correct answer is option (3/2, 3).
Jayson went to the market. He bought 1⅓ pounds of salami for $3.75. make a graph that shows this relationship
To create a graph that shows the relationship between the weight of salami and its cost, you can use a coordinate system with the weight (in pounds) on the x-axis and the cost (in dollars) on the y-axis.
Since Jayson bought 1⅓ pounds of salami for $3.75, we can plot this point on the graph.
The coordinate (1⅓, $3.75) can be converted to a mixed number to simplify plotting. 1⅓ is equal to 4/3.
Therefore, the point on the graph is (4/3, $3.75).
The graph would look something like this:
```
|
|
|
Cost ($)|
|
|
+------------------------
0 4/3 (1⅓) Weight (in pounds)
```
The point (4/3, $3.75) would be plotted slightly to the right of the midpoint between 1 and 1.5 on the x-axis, and the same height as $3.75 on the y-axis.
Please note that the actual scale and appearance of the graph may vary depending on the size and divisions of the coordinate system you are using.
Talia noticed a sale at her favorite store. The points on the graph show how many items she bought of each. T-shirts were selling for $5 each, long sleeve shirts were $10 each, jeans were discounted to $15 each, and sweaters were on sale for $25 each. Name the point corresponding to the number of pairs of jeans Talia purchased.
To determine the point corresponding to the number of pairs of jeans Talia purchased on the graph, we need more information such as the specific coordinate points or the equation of the graph. Without that information, it is not possible to identify the exact point corresponding to the number of pairs of jeans Talia purchased.
If you have the specific coordinate points or the equation of the graph, please provide it, and I will be able to help you identify the point.
