Your local hardware store is having a 35% off everything sale. But Wait!!!! For the next 3 days they
are offering a coupon to save an additional 30%. If the store applies the sale price then applies the
coupon, find each of the following. Let a represent the price of any item. Round all decimals to 4
decimal places.
Write an function that will directly calculate the final price on an item.
What percentage is actually being saved by the costumer?
1. The function that will directly calculate the final price on an item is " a * 0.455".
2. The percentage that is actually being saved by the custumer is 54.5%.
Function which will calculate the final price on an item:The final price of an item after the discount and coupon can be calculated using the following function:
Final price = a * (1 - 0.35) * (1 - 0.30)
Final price = a * 0.455
This function first applies the 35% discount, which reduces the original price (a) to 65% of its value. Then, it applies the 30% coupon to the discounted price, which reduces it to 70% of its value.
What percentage is actually being saved by the custumer?Original price = $100
Sale price (35% off) = $100 * (1 - 0.35)
Sale price (35% off) = $65
Final price = $65 * (1 - 0.30)
Final price = $45.50
Savings = $100 - $45.50
Savings = $54.50
Percentage saved:
= (Savings / Original price) * 100%
= ($54.50 / $100) * 100%
= 54.5%

Find the volume of the composite. The solid below is a square prism with a cylinder
cut out of it. Round to the nearest whole centimeter.
Answer:
17,242 cm³
Step-by-step explanation:
Step 1:
Volume of square prism = (area of base) * height
Volume of square prism = (25 * 30) * 25
Volume of square prism = 750 * 25
Volume of square prism = 18,750 cm³
Step 2:
Volume of cylinder = (area of base) * height
Volume of cylinder = (π * (8/2)²) * 30
Volume of cylinder = 16π * 30
Volume of cylinder = 480π
Volume of cylinder ≈ 1,508 cm³
Step 3:
Volume of composite = (Volume of square prism) − (Volume of cylinder)
Volume of composite = 18,750 cm³ − 1,508 cm³
Volume of composite = 17,242 cm³
Betsy is working on draining her pool for the winter. Her pool has 1,200 gallons of water and can drain 100 gallons an hour. After 5 hours, how much water will still be in the pool?
After 5 hours, there will be 700 gallons of water still in the pool.
After 5 hours, how much water will still be in the pool?Given that, the pool has 1,200 gallons of water and can drain 100 gallons an hour.
After 5 hours, the total amount of water drained from the pool will be 100 gallons per hour times 5 hours, or 500 gallons.
= 100 gallons × 5
= 500 gallons
To find out how much water will still be in the pool, we need to subtract the amount of water drained from the original amount "y":
This forms an equation.
Amount of water still in the pool = original amount - water drained from the pool.
y = 1,200 gallons - 500 gallons
y = 700 gallons

First to answer this question the quickest is rewarded branliest + 100 points
Answer:
Minimum--> 250
Q1--> 255
Q2--> (Median): 307
Q3--> 433
Maximum-->507
Step-by-step explanation:
To find the five-number summary of this data set, we need to determine the minimum value, maximum value, and three quartiles (Q1, Q2, Q3) which divide the data into four equal parts.
First, we need to sort the data set in ascending order:
{ 250, 253, 255, 267, 307, 425, 433, 435, 507 }
Minimum: 250
Maximum: 507
To find the quartiles, we need to find the median of the entire data set (Q2) and then the medians of the two halves of the data set, which will give us Q1 and Q3.
Q2 (Median): The median of the entire data set can be found by averaging the two middle numbers.
Q1: The median of the lower half of the data set is 255, which is the middle value of { 250, 253, 255, 267, 307 }. Therefore, Q1 = 255.
Q3: The median of the upper half of the data set is 433, which is the middle value of { 425, 433, 435, 507 }. Therefore, Q3 = 433.

percent did the average daily unexcused absences change from September to October?
There are 260 students who attend Juniper Middle School. The average daily unexcused absences increased by 25% from September to October.
How to calculate . How many students attend Juniper Middle Schoola. Let's assume that the total number of students at Juniper Middle School is "x."
Given that 55% of the students are in the 8th grade, we can write:
0.55x = number of 8th grade students
And since the remaining 117 students are in 7th grade, we can write:
x - 0.55x = 117
0.45x = 117
x = 260
Therefore, there are 260 students who attend Juniper Middle School.
b. To find the percent change from September to October, we can use the formula:
percent change = ((new value - old value) / old value) x 100%
Substituting the given values, we get:
percent change = ((6 - 4.8) / 4.8) x 100%
percent change = (1.2 / 4.8) x 100%
percent change = 25%
Therefore, the average daily unexcused absences increased by 25% from September to October.

The surface area of the rectangular prism is 72 square meters.
Describe Rectangular Prism?A rectangular prism, also known as a rectangular parallelepiped, is a three-dimensional figure that consists of six rectangular faces. It is a polyhedron with two identical and parallel bases, which are rectangles, and four rectangular lateral faces. The height of the prism is the perpendicular distance between the two bases. The volume of a rectangular prism is given by the formula V = l × w × h, where l, w, and h are the length, width, and height of the prism, respectively. The surface area of a rectangular prism is given by the formula SA = 2lw + 2lh + 2wh, where l, w, and h have the same meanings as in the volume formula. Rectangular prisms are commonly encountered in everyday life, such as in the shape of boxes, rooms, and buildings.
The surface area of a rectangular prism can be found by adding up the area of all its faces.
Area of blue rectangles:
= 2 x (length x width)
= 2 x (2.4m x 2m)
= 9.6m²
Area of green rectangles:
= 2 x (length x width)
= 2 x (2.4m x 3m)
= 14.4m²
Area of yellow rectangles:
= 2 x (length x width)
= 2 x (2m x 3m)
= 12m²
Total surface area = sum of all face areas
= (2 x blue rectangles) + (2 x green rectangles) + (2 x yellow rectangles)
= 2(9.6m²) + 2(14.4m²) + 2(12m²)
= 19.2m² + 28.8m² + 24m²
= 72m²
Therefore, the surface area of the rectangular prism is 72 square meters.

Ruby wants to find the height of the tallest building in her city. She stands 190 feet away from the building. There is a tree 31 feet in front of her, which she knows is 20 feet tall. How tall is the building? (Round to the nearest foot.)
To solve this problem, we can use similar triangles. Let's call the height of the building "h". Then, we have two similar triangles: one formed by Ruby, the tree, and the top of the tree; and the other formed by Ruby, the building, and the top of the building.
We know that the height of the tree is 20 feet, and the distance from the tree to Ruby is 31 feet. We also know that the distance from Ruby to the building is 190 feet.
Using these values, we can set up a proportion:
h / (190 + 31) = 20 / 31
Simplifying the proportion, we get:
h / 221 = 20 / 31
Multiplying both sides by 221, we get:
h = (20 / 31) * 221
h ≈ 143.23
Therefore, the height of the building is approximately 143 feet. Rounded to the nearest foot, the height of the building is 143 feet.

1. bmi calculator: design a program in raptor that prompts user to enter a person's weight in number of pounds and height in number of inches, then calculate that person's body mass index (bmi) using the formula below, and finally display the person's weight, height, and bmi. bmi
The program uses the conversion factors of 2.205 pounds per kilogram and 39.37 inches per meter to convert the input values to the correct units for the formula.
To design a program in Raptor that prompts the user to enter a person's weight in pounds and height in inches, and then calculates and displays their body mass index (BMI), we can follow these steps:
Start by opening Raptor and creating a new program.
Add three input symbols to prompt the user for their weight, height, and a constant value for BMI. Label each input symbol accordingly.
Add three assignment statements to assign the input values to variables. We can use the labels we assigned to the input symbols as variable names to make the code more readable.
Add two calculation statements to calculate the person's BMI using the formula [tex]BMI = (weight in pounds * 703) / (height in inches)^2.[/tex]Assign the result to the BMI variable.
Add three output symbols to display the person's weight, height, and BMI. We can concatenate strings with the variable values to make the output more informative.
Finally, save the program and run it to test it with different input values.
Here's what the program would look like:
Start
// Prompt the user for weight, height, and BMI
Input "Enter weight in pounds:", weight
Input "Enter height in inches:", height
Input "BMI:", bmi_constant
// Calculate BMI
Set weight_in_kg = weight / 2.205 // Convert weight to kilograms
Set height_in_m = height / 39.37 // Convert height to meters
[tex]Set bmi = weight_in_kg / (height_in_m ^ 2)[/tex] // Calculate BMI
// Display results
Output "Weight: " + weight + " lbs"
Output "Height: " + height + " in"
Output "BMI: " + bmi
Stop
When the program is run, it will prompt the user to enter their weight, height, and a constant value for BMI. It will then calculate the person's BMI using the formula, convert the weight to kilograms and the height to meters, and display the results along with the original weight and height values. The program uses the conversion factors of 2.205 pounds per kilogram and 39.37 inches per meter to convert the input values to the correct units for the formula.

Trey purchases 200 shares of Turner stock for per share. Trey pays in cash to complete the purchase. One year later, Trey sells the stock for per share. Part 2 Calculate the return that Trey earned on his investment of .
Answer: Formula
Step-by-step explanation:
Stocks x per share = return
Trey's return on investment, if the stock paid no dividends during the year, is 14.29%.
We have,
Purchase price per share: $50
Number of shares purchased: 200
Total purchase cost (excluding loan interest):
Purchase price per share * Number of shares purchased
= $50 * 200
= $10,000
Loan amount: $5,000
Loan interest rate: 10%
Interest paid on the loan:
Loan amount * Interest rate
= $5,000 * 10%
= $500
Total purchase cost (including loan interest):
Total purchase cost + Loan interest
= $10,000 + $500
= $10,500
Selling price per share: $60
Total revenue from selling the stock:
Selling price per share * Number of shares sold
= $60 * 200
= $12,000
Return on investment (ROI):
(Total revenue - Total purchase cost) / Total purchase cost
ROI = ($12,000 - $10,500) / $10,500
Simplifying the expression:
ROI = $1,500 / $10,500
ROI = 0.1429 (approximately)
To express the ROI as a percentage:
ROI as a percentage = 0.1429 * 100 = 14.29%
Therefore,
Trey's return on investment, if the stock paid no dividends during the year, is 14.29%.
