Determine if the table shows a proportional relationship. x 18.2 49.2 45.9 y 9.1 24.6 15.3 Yes, it is proportional because all y over x ratios are equivalent to one half. Yes, it is proportional because all y over x ratios are equivalent to one third. No, it is not proportional because 9.1 over 18.2 does not equal 24.6 over 49.2. No, it is not proportional because 9.1 over 18.2 does not equal 15.3 over 45.9.
Answer: No, it is not proportional because 9.1 over 18.2 does not equal 15.3 over 45.9.
Step-by-step explanation: 9.1 over 18.2 equals 0.5 but 15.3 over 45.9 is 1/3 (.3 repeating).
hello, your answer is No, it is not proportional because 9.1 over 18.2 does not equal 15.3 over 45.9.

The equation c = 5m represents how many ice cream cones (c) are sold within a certain number of minutes (m) at a certain ice cream shop.
Determine the constant of proportionality.
5
1
one fifth
25
Answer:
The COP of problem is 5 because the 5m means 5 per minute, which means that the cop is 5.
Answer: 5
Step-by-step explanation:
The constant of proportionality is 5 because here is the formula for this sort of question.
y=kx The k is the constant of proportionality and we can substitute the k for 5.
Ok, maybe that wasn't very helpful but the simplest way to know is this.
The 5 is the constant of proportionality because the constant of proportionality is the same thing as the slope (hopefully you know what slope is). The slope is the rate of change.
C is the y because the number of cones DEPENDS on the number of minutes (the number of minutes is X). The number of cones change by each minute.
Example:
c=5(3)
c=15 (15 cones)
or
10=5x
10/5=5x/5
2=x
Just use substitution.
Okay sorry if this was confusing, I just am not good at explaining this even though I know what it is.
Simple answer: It's 5

The table shows the proportional relationship between the number of tickets required per game at a carnival.
Games 3 9 15
Tickets 12 36 60
Determine the constant of proportionality.
Answer:
4
Step-by-step explanation:
Divide the larger number (tickets) by the smaller number (games):
12 / 3 = 4
36 / 9 = 4
60 / 15 = 4
The required value of the contant of proportionality is given as 1/4.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
Let G be the number of games and T be the number of tickets,
G ∝ T
So,
G = kT
From the table,
3 = 12k
T = 3 / 12
T = 1/4
Thus, the required value of the contant of proportionality is given as 1/4.

The original price for an item is $95, the sale price is $61.75. What is the discount?
Answer:
To find the discount on an item, you need to subtract the sale price from the original price and then multiply the result by 100 to express it as a percentage. In this case, the discount would be calculated like this:
Discount = (Original price - Sale price) * 100
Plugging in the prices from the question, we get:
Discount = (95 - 61.75) * 100 = 33.25 * 100 = 3325%
So, the discount on the item is 3325%. This means that the item is being sold for 33.25% less than its original price.
Step-by-step explanation:
Answer: 35%
Step-by-step explanation:
95 - 61.75 = 33.25
33.25 : 95 = 0.35 = 35 %

(Multi-Step Percent Problems HC) Predict the cost of a meal for a family of four between $50 and $100. Be sure to include dollars and cents. Part A: If the family has a 20% off coupon, calculate the new price of the meal. Show all work or explain your steps. (6 points) Part B: Calculate a 20% tip using the new price. What is the final cost of the meal? Show all work or explain your steps. (6 points)
Answer:
Part A: To find the cost of a meal for a family of four between $50 and $100, we need to pick a number within that range. Let's assume that the meal costs $75. If the family has a 20% off coupon, we need to multiply the cost of the meal by 20% to find the discount. This gives us $75 * 20% = $15. Therefore, the new price of the meal after the discount is $75 - $15 = $60.
Part B: To calculate a 20% tip using the new price, we need to multiply the new price by 20%. This gives us $60 * 20% = $12. Therefore, the final cost of the meal with the tip included is $60 + $12 = $72.

Answer:
y = -x + 60
Step-by-step explanation:
From point (0, 60) to point (60, 0), the rise is -60, and the run is 60.
slope = m = rise/run = -1
The y-intercept, b, is 60.
y = mx + b

10 onions filled 1/2 of a planter. onions will fill 1 planter
Answer:
20 onions (?)
Step-by-step explanation:
if 10 onions fill 1/2 (or one-half) of the planter then by adding 10 more onions the planter would be full.
(10= 1/2)
(10+ 10 = 20)
(1/2 + 1/2= 1)
20 onions will fill 1 planter.

Write an equation to show the proportional relationship in the table.
Answer:
y=65x
f(x)=65x
Step-by-step explanation:
Let x be time and y be trees planted.
Using the generic equation y=mx+b we can assume "Trees planted=slope x Time+y intercept.
We find the slope, 65, by using the formula m=y2-y2/x2-x1.
m=325-130/5-2
m=195/3
m=65.
Now, to find the y-intercept, let's replace the known variables with unknown ones.
130=65(2)+b
130=130+b
130-130=b
b=0
The result is y=65x.
In function notation, f(x)=65x.

To solve for the value of "a", we'll need to use the Pythagorean Theorem.
Pythagorean Theorem: a^2 + b^2 = c^2
---a and b are the legs of the triangle and c is the hypotenuse
Plug in known values and simplify:
a^2 + (9)^2 = (12)^2
a^2 + 81 = 144
a^2 = 63
a = sqrt(63)
The number that should go beneath the radical symbol is 63.
Hope this helps!
Recall that rational numbers are numbers that can be represented as the ratio, or fraction, of two integers. When expressed as decimals, rational numbers either terminate or repeat. For the following rational numbers, use long division to rewrite each fraction as a decimal number. Then, classify each decimal equivalent as terminating or repeating.

5 2/7 repeating or terminating
7/16 repeating or terminating
14 5/9 repeating or terminating
3/22 repeating or terminating
Answer:
Repeating
Terminating
Repeating
Repeating
Step-by-step explanation:
5 2/7 as improper fraction is 37/7 and it equals 5.28571428571 which makes it repeating because the numbers don't stop.
7/16 is equal to 0.4375 making it terminate because the numbers stop.
14 5/9 as an improper fraction is 131/9 and 131/9 is 14.5555555556 and that is a never ending pattern so it is repeating.
3/22 is equal to 0.13636363636 it is repeating because the numbers never stop.

If Hurricane Nicole had a peak wind speed of 115 mph, what can you conclude?
We can conclude that only three other storms had higher peak wind speeds than Hurricane Nicole.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Given that Min: 45, LQ: 50, M: 70, UQ: 115 and Max: 165
If Hurricane Nicole had a peak wind speed of 115 mph, we can conclude that it was one of the most intense storms of the year, as it had the same peak wind speed as the upper quartile (UQ) of the 15 named storms that formed in the North Atlantic in 2016.
This means that only three other storms had higher peak wind speeds than Hurricane Nicole.
Hence, we can conclude that only three other storms had higher peak wind speeds than Hurricane Nicole.
