The table shows the proportional relationship between the price for a certain number of buckets of golf balls at a driving range.


Buckets 3 5 7
Price (dollars) 25.50 42.50 59.50


Determine the constant of proportionality.
25.5
17
9.5
8.5

Answers

Answer 1

Answer:

Step-by-step explanation:

25.50+17=42.50

42.50+17=59.50

so the numbers are constantly going up by 17 if you add the .50 you will change the number by 1 unit

Answer 2

Answer: 17 is the Constant

Step-by-step explanation:
Buckets: 3 5 7

Price (dollars):25.50 42.50 59.50
If you were to do
25.50-42.50 you would get 17
42.50-59.50 you also would get 17
You dont actually need to do the formula, if the answer IS proportional, then you can just do the first number minus the second, and the second minus the third.
There is also the formula that you can use to get the answer, which the other person did.
( Constant of Proportionality )

What is Constant of Proportionality?
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

Ricardo’s goal was to run 40 laps. At the end of the week, he ran 125% of his goal. How many laps is that?

Answers

Answer: He ran 50 laps.

Step-by-step explanation:

40 x 1.25 = 50

Answer:

50

Step-by-step explanation:

40/1   =   100/1

125% = 100/100   +   25/100

25% of 40 = 10

so you have the 40 laps which equal 100% and you also have 25 percent of the from the 125% and 25 percent of 40 is 10 so the answer is 40 plus 10 wich is 50

All students in Ridgewood Junior High School either get their lunch in the school cafeteria or brought it from home on Tuesday. 2% of students brought their lunch. 50 students brought their lunch. How many students in total are in Ridgewood Junior High School?
Multiply/scale up to solve.

Answers

Answer:

2% can be written as 0.02
So the total amount of kids multiplied by 0.02 is 50

Then 50 divided by 0.02 is 2500 which is the total amount of kids at the school.

Hope this helps!

Fishing Adventures rents small fishing boats to tourists for day-long fishing trips. Each boat can only carry 1200 pounds of people and gear for safety reasons. Assume the average weight of a person is 150 pounds. Each group will require 200 Ibs of gear for the boat plus 10 lbs of gear for each person. Create an inequality describing the restrictions on the number of people possible in a rented boat. Graph the solution set on a number line.

Answers

Answer:

To write an inequality that illustrates the weight limit for a group of adults and children on the fishing boat, let's assume that the letter a corresponds to the number of adults and the letter c corresponds to the number of children.

So, let's calculate:

The total weight on the boat by people corresponds to:

Now, let's add 200 pounds of equipment to this amount, and remembering that the total weight cannot exceed 1200 pounds, so we will find the following inequality:

Or else:

The next step is to calculate the inequality for the passenger limit, remembering that this number cannot exceed 8:

Thus, we find a system of linear inequalities:

In order to be able to answer which of the groups can safely rent a boat, we will make the following calculations substituting the values in the inequalities found.

Group A has 4 adults and 2 children:

Group B has 3 adults and 5 children:

Group C has 8 adults and 0 children:

Answers

The probability that a student studied for 5 hours is 0.23 Or 23%.

What is probability?

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

A table is given where the first column represents the number of hours a student studied maths and the second column represents the number of students.

The sum of the second column is 30 so it is the total number of students

And only 7 of them studied mathematics for 5 hours.

Therefore, The probability that a student studied for 5 hours is,

= 7/30.

= 0.23 or 23%.
