12. A wall contains a rectangular window. The area (in square feet) of the window is represented by x ^ 2 - 14x + 48
a. Write a binomial that represents the height of the window.
b. Find the perimeter of the window when the height of the wall is 12 feet.
Answers
Answer :
a - binominal = an algebraic expression of the sum or the difference of two terms. So I put it in the perimter 12. 6+12=18. So the width would be 18. 18+12+18+12 = 30+30 = 60. just put that ig ??
Question : Is this RSM? Because if I knew the grade , advanced/normal/honors I would be able to help u more
Solve step by step : x=12 because it said the height is 12.
Inside, x-6, so therefor it would really be, 12-6. Which we know would be 6.
Perimeter : 60
now we know the inside is 6. The outside height is 12. 6+12=18. So the width would be 18. 18+12+18+12 = 30+30 = 60.

A retailer buys an item from a wholesaler and marks up the price by 20%. When time passes and the item is not sold, he discounts the item by 25%. The expression below represents the discounted price of the item.
Answers
Answer:
Step-by-step explanation:
To calculate markup by hand:
Determine your COGS (cost of goods sold). For example, $40.
Find your gross profit by subtracting the cost from the revenue. Our product sells for $50, so the profit is $10.
Divide profit by COGS. $10 / $40 = 0.25.
Express it as a percentage: 0.25 × 100 = 25%.
This is how to find markup... or simply use Omni's markup calculator!
The expression representing the discounted price of the item that is correct is C. The discounted price is p - 10%p, indicating that the retailer will lose 10% of his investment.
What is the discounted price?The discounted price is the selling price of an item less the discount.
The discount is usually stated in rates, showing the percentage of the reduction in the selling price.
Let the cost price = 100%
Markup = 20%
Selling price = 120% (100 + 20)
Discount = 25%
Discounted price (rate) = 120% x (1 - 25%)
= 90%
Difference between Discounted Price and the Cost Price = 10% (100% - 90%).
Thus, what the retailer loses is 10% of his investment cost, showing that Option C is correct.

Which inequality represents the number of books Brittany needs to read to receive the grand prize? Select the inequality that contains the least number of books that Brittany can read and still receive the grand prize.
A. x > 14
B. x > 10
C. x > 140
D. x > 50
Answers
Answer:
A. x > 14
Step-by-step explanation:
Answer: A
Step-by-step explanation:
First, its important to realize that x= the number of books the reads. We put a 10 in front of the x because for every 1 books she reads, she receives 10 points. If she needs 190 points total, and already has 50 points, we then need to find how many points she needs to get to 190. To find this, we subtract 50 from 190, and are left with 140 points remaining to reach 190.
10x+50>190
-50 -50
10x>140
now that we know that 10x needs to be greater than 140, we can solve. We can divide both sides by 10 in order to find that x>14. She needs to read more than 14 books in order to earn the grand prize
[tex]\frac{10x > 140}{10}[/tex] = x>140
The figure below is composed of a rectangle and two quarter circles. What is the area of the figure?
A) 132.97 cm^2
B) 94.48 cm^2
C) 75.24 cm^2
D) 209.94 cm^2
Answers
Answer:
A) 132.97 cm²
Step-by-step explanation:
first, find the area of the rectangle.
8×7=56
then, find the area of the two quarter circles (ill just calculate for a half circle since bith quarters are the same)
the radius is 7, qnd the formula for a half circle is 1/2(πr2 )
so just plug in and solve
1/2(×7²)
π×7² is 153.86
153.86/2 is 76.93
then add those two areas together
76.93+56 = 132.96 (i used 3.14 for pi, but im assuming this calls for the actual pi to be used, so just round to 132.97)

2 over 3 divided by 8?
Answers
Answer:
To divide 2/3 by 8, we can convert the division into multiplication by taking the reciprocal of the divisor (8) and multiplying it with the dividend (2/3). The reciprocal of 8 is 1/8, so we have:
2/3 ÷ 8 = 2/3 x 1/8
Multiplying the numerators and denominators, we get:
2/3 x 1/8 = 2/24
Simplifying the fraction, we get:
2/24 = 1/12
Therefore, 2/3 ÷ 8 = 1/12.
Step-by-step explanation:
[tex]\frac{2}{3}[/tex] ÷ [tex]\frac{8}{1}[/tex]
keep, switch, flip
[tex]\frac{2}{3}[/tex] x [tex]\frac{1}{8}[/tex]

Answer: 75
Step-by-step explanation:
Add the values given in the table
16+15+20+14+15 = 80
Yellow happens 20 times out of the 80 times total.
The experimental probability of yellow is 20/80 = 1/4 = 0.25 = 25%
If we do 300 trials, then we predict yellow to happen 0.25*300 = 75 times.

area= 1634.77
Answer:
520.89 cm²
Step-by-step explanation:
IN GIVEN QUESTION
The hubcap of the tire's circumference is 80.89 centimetres.
We must determine the radius of this hub cap, which we can do by using the circumference method to determine its area
now :
2πr = 80.89 cm
r = 80.89/ 2× 3.14
r = 12. 88 cm ( approx)
Area of hub cap = πr²
Area = 3.14 ×12.88² = 520.89 cm²

What is the area of a rectangle?The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.
Here, dimensions of small rectangle are length=9 ft and width=6.5 ft
Now area of a small rectangle = 9×6.5
= 58.5 square feet
Dimensions of large rectangle are length=18 ft and width=12.2 ft
Here, area of large rectangle = 18×12.2
= 219.6 square feet
Area of the mulch = 219.6-58.5 =161.1 square feet
The mulch cost $4.70 per sq. ft.
Total cost of mulch = 161.1×4.70
= $757.17
Therefore, the total cost of mulch is 757.17 dollars.

What is the surface area of the piece of cheese?
A. 14.5 square inches
B. 29 square inches
C. 32. square inches
Answers
As you can see in the diagram, the triangular prism has the following faces:
1) Two triangular faces
2) Three rectangular faces.
Surface area is the SUM of the areas of all of the faces.
Let us find these faces one by one:
1.
As you know, the area of the triangle is:
[tex]\frac{1}{2}* base*height[/tex]
Since, the base = 6 inches, and height = 4 inches;
Therefore, The area of ONE triangle = (1/2) * 6 * 4 = 12 inches squared.
In triangular prism, there are two triangles, therefore,
Two triangular faces = 2 * 12 inches = 24 inches squared --- (A)
2.
Now let us find the areas of three rectangular faces...
Since, two of the three rectangular faces are the same, therefore, we would find the area of one rectangular face, and multiple the result with two to get the total area of two rectangular faces.
Area of one rectangular face = base * height.
Since, base = 0.5 inches, height = 5 inches, therefore,
Area of one rectangular face = 0.5 * 5 = 2.5 inches squared.
Now that we have one rectangular face, therefore,
Area of two rectangular faces = 2 * 2.5 = 5 inches squared.
The area of the third rectangular base = 6 * 0.5 = 3 inches squared
Therefore,
The area of the three rectangular faces = 5 + 3 = 8 inches squared --- (B)
Now add both "area of two triangular faces(A)" and "area of three rectangular faces(B)" to get the final surface area of the triangular prism.
Surface Area of the triangular prism = Area of Two Triangular faces + Area of Three Rectangular faces
Surface Area = 24 + 8 = 32 inches squared
The surface area of the triangular prism = 32 inches squared.

First of all, you need to take one of the numbers (I choose 5,250) and divide it by the other (1,750) and multiply by 100. Like so:
5,250÷1,750=3×100=300 so 3%
