the points on the graph show how much chee pays for different amounts of noodles the graph shows
(2, 5)
(4, 10)
(6, 15)
(8, 20)
This suggests that Chee pays $5 for 2 noodles, $10 for 4 noodles, $15 for 6 noodles, and $20 for 8 noodles. The relationship between the amount of noodles and the cost seems to be linear, with a slope of $2.50 per noodle.
complete the statement about the graph. the cost of 20 pounds of noodles is $?
Unfortunately, the graph doesn't provide enough information to answer that question, as it only shows the cost for specific amounts of noodles between 2 and 8. We would need additional information, such as the cost per pound or the cost for different amounts beyond 8 pounds, to determine the cost of 20 pounds of noodles.
okay lets make it more simple for you. what is the cost of 20 pounds of noodles, when the equivalent ratio of pounds to dollars is (12, 30)
If the equivalent ratio of pounds to dollars is (12, 30), then the unit rate is $30 ÷ 12 = $2.50 per pound.
Therefore, the cost of 20 pounds of noodles would be:
Cost = Amount of noodles × Cost per pound
= 20 pounds × $2.50 per pound
= $50
So, the cost of 20 pounds of noodles would be $50.
Based on the given points on the graph, we can conclude that the relationship between the amount of noodles and the amount Chee pays is a linear relationship.
To find the equation of the line that represents this relationship, we can use the formula for the equation of a line: y = mx + b, where m is the slope and b is the y-intercept.
To find the slope (m), we can use the formula:
m = (change in y) / (change in x)
Using the points (2, 5) and (4, 10):
(change in y) = 10 - 5 = 5
(change in x) = 4 - 2 = 2
m = 5 / 2 = 2.5
So, the slope (m) is 2.5.
To find the y-intercept (b), we can substitute one of the given points into the equation. Let's use the point (2, 5):
y = mx + b
5 = 2.5 * 2 + b
5 = 5 + b
b = 5 - 5
b = 0
So, the y-intercept (b) is 0.
Therefore, the equation of the line that represents the relationship between the amount of noodles and the amount Chee pays is:
y = 2.5x + 0
Simplified as:
y = 2.5x
Based on the given graph points, we can see a pattern where the x-coordinate represents the amount of noodles and the y-coordinate represents the amount of money Chee pays. To find out how much Chee pays for a specific amount of noodles, we can use the equation of a straight line, which is in the form y = mx + b.
To determine the equation, we need to find the values of m (slope) and b (y-intercept). The slope (m) can be calculated using the formula:
m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are any two points on the line.
Let's calculate the slope using the points (2, 5) and (4, 10):
m = (10 - 5) / (4 - 2)
m = 5 / 2
m = 2.5
Now we have the slope (m = 2.5). To find the y-intercept (b), we can substitute one of the points into the equation and solve for b.
Using the point (2, 5):
5 = 2.5(2) + b
5 = 5 + b
5 - 5 = b
b = 0
So now we have the slope (m = 2.5) and the y-intercept (b = 0). Therefore, the equation for the graph is y = 2.5x.
To find out how much Chee pays for a specific amount of noodles, plug in the value of x (amount of noodles) into the equation and solve for y (amount of money paid).
For example, if Chee wants to buy 3 servings of noodles:
y = 2.5(3)
y = 7.5
Therefore, Chee would pay $7.50 for 3 servings of noodles based on the given graph.
