This graph shows a proportional relationship.
What is the constant of proportionality?
Enter your answer as a decimal in the box.
Answers
Answer:
The constant of proportionality is 0.3, or K=0.3.
Step-by-step explanation:
The chart I attached shows points that are plotted on the proportional line. In order to find the constant of proportionality from these points, you have to divide the amount of change by the number of years. For example, 3 divided by 10 or 6 divided by 20. This results in 0.3, which means that every year, there is 0.3 centimeters of change in the sea level.

a train passes through an intersection at the rate of 3 cars per 30 seconds. Assume that it takes 5 minutes for the train to completely pass through the intersection. How many cars does the train have all together
Answers
Answer:
30
Step-by-step explanation:
To answer this question, we need to figure out the amount of cars that the train has. The info we have is that the train is moving at 3 cars every 30 seconds. To make this easier to solve, we can multiply the rate by 2 to get the minutely rate, which is 6 cars per minutes. Then you multiply 6 by 5 and you get 30 cars on the train.

Jason spent $30 at a baseball game. He spent $10 on the ticket, $12 on nachos, and he bought a soda. He does not remember how much the soda was. Which of the following is an equation that can help him solve for his missing soda price?
A 10 + 12 + j = 30
B 30 = j -10 -12
C 30 + 10 + 12= j
D 12+ j -10 = 30
Answers
Answer: A
Step-by-step explanation: You are saying that when he bought all of these things he spent $30. So all of your items have to add up to 30. Answer A is saying Ticket+Nachos+Soda=total.
When you come across a problem like this, try sounding it out in your head. Even though the question is asking for an equation that would help find the missing soda price, j won’t be behind the equal sign because $30 is how much Jason spent in total. The ticket price, plus the nachos, plus the soda price equal 30 dollars, so A) would be the best option.
In order to solve the equation, since we’re dealing with money here and trying to reach $30, adding up the price of the ticket and the nachos makes the most sense:
10+12+j=30
22+j=30
$22 plus the soda price is $30, so in order to find j, find the difference between 22 and 30 ( basically 30-22) which is 8. the soda price was $8
To check your work, plug in $8 in place of j like this:
10+12+8
If the equation equals 30 (which it does), then the j value you came up with is right.

In the figure shown, which pair of angles must be supplementary?
(A) ∠AXY and ∠BXC
(B) ∠YXB and ∠BXC
(C) ∠AXD and ∠DXC
(D) ∠AXY and ∠AXD
Answers
Answer:
(C)
Step-by-step explanation:
What are supplementary angles?
Supplementary angles are angles that add up to 180°. They're usually adjacent angles, but not all the time.Given the information above, C) is correct because ∠AXD and ∠DXC are right angles. One right angle is worth 90°, so two adjacent right angles must be worth 180°, thus being supplementary.

To solve 1/3 -1/6, you need to make the fractions have the same common denominator. So since the denominator 3 needs to become 6, multiply 1/3 by 2 and you get 2/6.
So 2/6 -1/6 = 1/6
The correct answer is A.

Find the area and the circumference of the circle. Round your answers to the nearest hundredth.
Answers
Answer:
The circumference is 50.24 and the area is 200.96
Step-by-step explanation:
The way you get these answers is you take the radius which is 8 in this case and then you input it into the equations of finding circumference and area
Circumference: 2 times pi times radius so in this case 2 times 3.14 times 8
Area: pi times radius squared so 3.14 times 8 times 8
