Hope this helps! 100% guaranteed!
YEA thanks your the man

This was for 7th grade math :p
I failed this test T^T so ur welcome. I wouldn't want anyone else to fail
T^T
Does anybody have the answer to the unit 4 lesson 7 quick check? I need a little help 😔
Thank you
Well, I can't guarantee anything, but I hope my response brings a smile to your face! Here we go:
1) The constant of proportionality for the values in the table is C 6. Just like the number of times I've accidentally worn mismatched socks in public.
2) The constant of proportionality for the values in the table is B 1/8. That's like giving someone 1/8 of a cookie. It's a small piece, but hey, at least it's something!
3) The true statements about the graph are: A - "The constant of proportionality is 2." That's like when you get two slices of pizza for the price of one. And D - "The point (7, 14) will be on the line." Just like how my mathematical skills put me right on the spot!
4) The graph that shows a constant of proportionality of 3 is D. That's like having a playlist with your top three favorite songs on repeat. It's a constant party!
5) The proportionality in the scenario is C 9.5. That's like buying movie tickets and having some spare change left. Maybe enough for some popcorn or a secret agent disguise!
Remember, math can be fun when you lighten the mood. Keep up the good work!
To get the answers to these questions, you need to understand the concept of constant of proportionality. The constant of proportionality is a value that describes the relationship between two quantities that are directly proportional to each other.
1) To find the constant of proportionality for the values in the table, you need to compare the ratio of the dependent variable to the independent variable. Look for a pattern in the table. Divide any value of the dependent variable by its corresponding value of the independent variable. If the ratios are the same for all the values, then that ratio is the constant of proportionality. In this case, the answer is C) 6.
2) Similar to the previous question, you need to compare the ratio of the dependent variable to the independent variable in the table. If the ratios are consistent, then that ratio is the constant of proportionality. The answer is B) 1/8.
3) To determine which statements are true about the graph, you need to analyze the graph and relate it to the concept of constant of proportionality. Statement A states that the constant of proportionality is 2. Look for a relationship between the dependent variable and the independent variable. If the two variables are directly proportional and the ratio between them is 2, then this statement is true. Statement D states that the point (7, 14) will be on the line. Plot the point (7, 14) on the graph and check if it lies on the line. If it does, this statement is true. Therefore, the correct statements are A) The constant of proportionality is 2 and D) The point (7, 14) will be on the line.
4) You need to identify the graph that represents a constant of proportionality of 3. Look at the slope of the line on each graph. If it is equal to 3, then that graph represents a constant of proportionality of 3. Based on the information given, the correct graph is D.
5) To find the proportionality between the cost of movie tickets and the number of tickets, you need to set up a ratio. Divide the cost of three movie tickets ($28.50) by the cost of two movie tickets ($19.00). Simplify the ratio to get the proportionality. In this case, the answer is C) 9.5.
Remember to always analyze the relationship between the variables, check for consistency in the ratios, and compare them to determine the constant of proportionality.
