james has been subscribed to our bronze address rental package. he pays us £12.87 per quarter in advance he has been using our services for 1 year and has paid for 4 quarters in full. he has told us he wants to cancel his subscription and is requesting a refund for 1 month's subscription
James is eligible for a refund of £47.19 for one month's subscription.
To calculate the refund for James's subscription, we need to determine the cost of one month's subscription and subtract it from the total amount he has paid for four quarters.
James pays £12.87 per quarter, which means he pays £12.87 x 4 = £51.48 for a full year in advance.
To find the cost of one month's subscription, we divide the annual cost by 12 (number of months in a year):
£51.48 / 12 = £4.29
The cost of one month's subscription is £4.29.
To calculate the refund, we subtract the cost of one month's subscription from the total amount James has paid:
£51.48 - £4.29 = £47.19
We must figure out the price of a month's membership and deduct it from the total amount James has paid for four quarters in order to compute the refund for his subscription.
James pays £12.87 every quarter, or £12.87 x 4 = $51.48 for the entire year up front.
We divide the yearly cost by 12 (the number of months in a year) to get the price for a month's subscription:
£51.48 / 12 = £4.29
Therefore, a membership for one month costs £4.29 in total.
We deduct the price of a single month's membership from James' overall payment to determine the refund:
£51.48 - £4.29 = £47.19

Wayne wants to fence in an area adjacent to his house for his daughter's bunnies. He has 45 feet of fencing to work with. What is the maximum area he can enclose for Vayla's bunnies? Do not round your answer. ft³
The maximum area Wayne can enclose for Vayla's bunnies is 126.5625 square feet.
The perimeter of a rectangle is given by the formula: P = 2L + 2W.
In this case, the perimeter is given as 45 feet: 2L + 2W = 45.
Rearranging the equation for the perimeter, we have: 2L = 45 - 2W.
Solving for L, we get: L = (45 - 2W)/2 = 22.5 - W.
Now, we can express the area A in terms of W:
A = L x W = (22.5 - W) x W.
To find the maximum area, we take the derivative of the area with respect to W and set it equal to zero:
dA/dW = 22.5 - 2W = 0.
22.5 - 2W = 0
2W = 22.5
W = 22.5/2
W = 11.25.
and, L = 22.5 - W
L = 22.5 - 11.25
L = 11.25.
Therefore, the dimensions of the rectangle that will maximize the area with 45 feet of fencing are L = 11.25 feet and W = 11.25 feet.
Finally, we can calculate the maximum area:
A = L x W
A = 11.25 x 11.25
A = 126.5625 square feet.
Thus, the maximum area Wayne can enclose for Vayla's bunnies is 126.5625 square feet.

The lateral area of a cone is 612 x pie m2. The radius is 14.2 cm. What is the slant height to the nearest tenth of a centimeter?
Rounding to the nearest tenth of a centimeter, the slant height is approximately 43.1 centimeters.
The lateral area of a cone is given by the formula L = πrs, where L is the lateral area, r is the radius, and s is the slant height.
We are given that the lateral area L is equal to 612π m², and the radius r is 14.2 cm (0.142 m).
We can rearrange the formula to solve for the slant height s:
L = πrs
612π = π × 14.2 × s
Dividing both sides by π and 14.2:
612 = s × 14.2
Now, solve for s:
s = 612 / 14.2
s ≈ 43.0986
L = rs, where L is the lateral area, r is the radius, and s is the slant height, gives the lateral area of a cone.
We are informed that the radius r is 14.2 cm (0.142 m), and the lateral area L is equivalent to 612 m2.
To solve for the slant height s, we may rewrite the formula as follows:
L = πrs 612π = π × 14.2 × s
612 = s 14.2 after dividing both sides by and 14.2
Next, find the value of s: s = 612 / 14.2 s 43.0986

Find the number of students getting less than 45 marks. Find the maximum number of students getting the same marks. Find the average marks obtained by the students in the class. Find the number of students getting more than average marks.
a) To find the number of students getting more than 45 marks, we count the students whose marks are greater than 45 in the given list.
In the given list, the students with marks greater than 45 are: 50, 49, 47, 48, 49, 48, 47, 49, 48, 50, 47, 49, 48, 46, 47, 48, 47.
Counting these numbers, we find that there are 17 students who obtained more than 45 marks.
b) To find the number of students getting less than 45 marks, we count the students whose marks are less than 45 in the given list.
In the given list, the students with marks less than 45 are: 44, 44, 42, 41, 41, 42, 41, 44, 44, 42, 45, 45, 45, 44, 45.
Counting these numbers, we find that there are 15 students who obtained less than 45 marks.
c) To find the maximum number of students getting the same marks, we look for the mark that appears most frequently in the given list.
In the given list, the marks obtained by the students are: 44, 50, 44, 49, 42, 47, 45, 42, 44, 48, 49, 48, 47, 49, 47, 41, 45, 48, 41, 48, 41, 42, 47, 49, 49, 48, 50, 47, 49, 48, 46, 44, 45, 45, 46, 44, 42, 47, 48, 45.
Counting the frequency of each mark, we find that the marks 47 and 48 appear most frequently, with a count of 6 each. Therefore, the maximum number of students getting the same marks is 6.
d) To find the average marks obtained by the students in the class, we sum up all the marks and divide by the total number of students.
Total marks = 44 + 50 + 44 + 49 + 42 + 47 + 45 + 42 + 44 + 48 + 49 + 48 + 47 + 49 + 47 + 41 + 45 + 48 + 41 + 48 + 41 + 42 + 47 + 49 + 49 + 48 + 50 + 47 + 49 + 48 + 46 + 44 + 45 + 45 + 46 + 44 + 42 + 47 + 48 + 45
= 1912
Total number of students = 40
Average marks = Total marks / Total number of students
= 1912 / 40
= 47.8
Therefore, the average marks obtained by the students in the class is 47.8.
e) To find the number of students getting more than the average marks, we count the students whose marks are greater than 47.8.
In the given list, the students with marks greater than 47.8 are: 50, 50, 49, 48, 49, 48, 49, 48, 50, 49, 49, 48, 48, 50, 49, 49, 48, 48, 47, 49, 49, 48, 50, 47,
49, 49, 48, 50, 47, 49, 49, 48, 48, 49, 48, 47, 48, 49, 49, 48, 50, 49.
Counting these numbers, we find that there are 40 students who obtained more than the average marks.

Jane received a $80 gift card for a coffee store. She used it in buying some coffee that cost $7.56 per pound. After buying the coffee, she had $49.76 left on
her card. How many pounds of coffee did she buy?
Answer:
Jane spent on coffee.
She started with $80 on her gift card and ended with $49.76, so she spent:
80 - 49.76 = $30.24
We know that she bought coffee that cost $7.56 per pound, so we can set up an equation to find how many pounds of coffee she bought:
7.56x = 30.24
where x is the number of pounds of coffee she bought.
Solving for x, we get:
x = 30.24 / 7.56 = 4
So Jane bought 4 pounds of coffee with her gift card.

How can you use the double number line diagram to find what percent 120 is of 150?
We can say that 120 is 80% of 150.The percentage that 120 is of 150 will be the length of this line divided by the length of the entire double number line (which is 100%).
To use the double number line diagram to find what percent 120 is of 150, we first need to plot the two numbers on the double number line. We can do this by drawing a horizontal line and labeling it with the two numbers, 120 and 150, and then dividing the line into equal segments.
Next, we can find the difference between the two numbers (150-120=30) and use this to label the corresponding points on the double number line. The point representing 120 should be 3/4 of the way between the two numbers (since 120 is 3/4 of 150).
Finally, we can use the double number line to find the percentage that 120 is of 150. To do this, we can draw a vertical line from the point representing 120 up to the top of the double number line.
