A portrait without its frame has a height 1.5 times its width w, in inches. Its frame is 2 in. wide all along its perimeter. What is an expression for the area of
the framed portrait in terms of w?
A. 1.5W2 + 5W + 4
B. 1.5w2 + 8w + 8
C. 1.5w2 + 8.5w + 16
D. 1.5w2 + 10w + 16
Answer:
The correct answer is A. 1.5w² + 5w + 4
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Height of the portrait = 1.5 times its width in inches
Frame = 2 inches all along its perimeter
2. What is an expression for the area of the framed portrait in terms of w?
Let's recall that the area of a rectangle is length or height * width.
A = height * width
Now, we can replace in terms of w:
A = 1.5w * w
But we need to add the 2 inches of the frame, this way:
A = (1.5w + 2) * (w + 2)
A = 1.5w² + 2w + 3w + 4
A = 1.5w² + 5w + 4
The correct answer is A. 1.5w² + 5w + 4
Final answer:
The expression for the area of the framed portrait in terms of w is 1.5w^2 + 8w + 8.
Explanation:
To find the expression for the area of the framed portrait, we need to consider the dimensions of both the portrait and the frame. Let's assume the width of the portrait is w inches. According to the given information, the height of the portrait without the frame is 1.5 times the width, so the height is 1.5w inches.
To calculate the dimensions of the framed portrait, we need to add 2 inches to the width and height for the frame. The width of the framed portrait is w + 2 inches, and the height is 1.5w + 2 inches.
The area of the framed portrait is equal to the product of its width and height. Therefore, the expression for the area, in terms of w, is (w + 2) * (1.5w + 2). When we simplify this expression, we get 1.5w2 + 8w + 8.
How much larger is the volume of a cylinder with a height of 8.5 inches and a radius of 4 inches compared to a cylinder with a volume of 390 cm^3?
______cm^3 larger
The first cylinder is larger by 6607.9 cm³.
Step-by-step explanation:
Step 1: Calculate volume of cylinder 1 using formula V(1) = πr²h, where r = 4 in = 10.16 cm and h = 8.5 in = 21.59 cm⇒ V(1) = 3.14 × 10.16² × 21.59 = 6997.9 cm³
Step 2: Find the difference between the volumes of the 2 cylinders.V(2) = 390 cm³
⇒ Difference = 6997.9 - 390 = 6607.9 cm³

Calculate the area of the regular pentagon below:
Answer:
1064.8 in^2
Step-by-step explanation:
12.1 x 17. 6 / 2 to find one half of a triangle will equal 106.48
there are 10 triangle therefore 106.48 x 10 = 1064.8
Answer:
532.4 in²
Step-by-step explanation:
The area (A) of the regular pentagon is calculated as
A = 0.5 × perimeter × apothem
Perimeter = 5 × 17.6 = 88 in
The apothem is the segment from the centre to the midpoint of one of the sides.
Here the apothem = 12.1 in, thus
A = 0.5 × 88 × 12.1 = 44 × 12.1 = 532.4 in²
In the basketball game, you made 12 baskets and scored 19 points. How many 2-point shots did you make? How many free throws did you make?
Answer:
0.5
Step-by-step explanation:
Answer:12 baskets - 19pts
2×7= 14pts
1×5= 5pts
Therefore: (7+5) baskets= (14+5)pts
> 12 baskets = 19pts
Step-by-step explanation:
For a 2-point shots to make 14pts, there will be 7 baskets/throws.
A free throw shot is 1pts, so there has to be about five (5) free throws which will make 5pts.
Therefore, there will be (7+5 baskets) 12 shots in total.
2-point shots = 7
1-free throws = 5

The angle measure of m∠ACB (x°) is 39°.
Step-by-step explanation:
Let us name the joining points as ABC and ABC forms triangle with extended lines. (refer the image)
We have to find the value of m∠ACB = x°.
the given data,
m∠A=68°.
m∠B =107°.
To find m∠CAB,
Let us consider that AB is a line traversed by a line C intersecting at A. (refer diagram)
Using the theorem of corresponding angles theorem, when a line intersects another line, then the angles opposite each other is equal to each other.
m∠A=m∠CAB.
m∠CAB =68°.
To find m∠ABC,
Let us consider AB is a line.(refer diagram)
Using the straight line proof, the total of angles in a straight line is 180°.
Thus m∠ABC+m∠B=180°.
m∠ABC+107°=180°.
m∠ABC=180°-107°.
m∠ABC=73°.
Finally we have to find the value of x° that is m∠ACB.
Using the interior angles proof, the sum of interior angles of triangle is 180°.
⇒m∠ABC+m∠CAB+m∠ACB=180°.
73°+68°+m∠ACB=180°.
141°+m∠ACB=180°..
m∠ACB=180°-141°.
m∠ACB=39°.
Thus the angle measure of m∠ACB (x°) is 39°.
adam sells medical magazine and books. the table shows price for both Magazine £8
books £15
each week Adam earns £ 200 basic pay 10% of the magazine price for each sold
15% of the books price for each sold
last week Adam sold 42 magazines and 14 books
work out the total amount Adam earned last week
Adam earned a total of £265.10 last week.
Step-by-step explanation:
Step 1; Adam earns a basic pay of £200 each week. He earns 10% of the magazine price for each sold and 15% of the book price for each sold. Each magazine costs £8 and each book costs £15. He sells 42 magazines and 14 books.
Money earned for selling a magazine = 10% × £8 = 0.10 × £8 = £0.80,
Money earned for selling a book = 15% × £15 = 0.15 × £15 = £2.25,
Money earned for selling 42 magazines = 42 × £0.80 = £33.60,
Money earned for selling 14 books = 14 × £2.25 = £31.50,
Money earned for selling 42 magazines and 14 books = £33.60 + £31.50 = £65.10.
Step 2; Now we have to calculate his last week's salary which is his weekly pay and his earnings from selling magazines and books. We found that he earned £31.50 from selling books and magazines. His weekly salary is £200.
Last week's salary = £200 + £65.10 = £265.10.
Answer: £265.10
Step-by-step explanation:
Adam gets £200 each week.
10% of 42 magazines
Magazines opcost £8
10% × £8 = 0.10 × £8 = £0.80
42 × £0.80 = £33.60
15% of 14 books
Each book cost £15
15% × £15 = 0.15 × £15 = £2.25,
14 × £2.25 = £31.50
Last Week's Salary:
£31.50 + £33.60 = £65.10
£200 + £65.10 = £265.10 (last weeks salary)

Leila‘s coffee shop makes a blend that is a mixture of two types of coffee type a coffee cost Layla $4.85 per pound and type B coffee cost $5.90 per pound this month leather made it 142 pounds of the blend for the total cost of $781.10 how many pounds of type B coffee did she use
Answer:
Therefore she used (142-54)=88 pounds of type B coffee.
Step-by-step explanation:
Given, Leila's coffee shop makes a blend that is a mixture of two types of coffee.Type A coffee $4.85 per pound and type B coffee cost $5.90 per pound. She made 142 pounds of the blend for the total cost of $781.10.
The cost price of the blend per pound is = $(781.10÷142)
=$5.5
Let , the amount type A in the blend be x
Then the amount of type B in the blend is (142-x)
The cost price of x pound of type A coffee is = $(4.85×x) =$4.85x
The cost price of(142- x) pound of type B coffee is =$(142-x)×5.90
According to the problem,
4.85x+(142-x)×5.90 = 781.10
⇔4.85x +837.8-5.90x=781.10
⇔1.05x=56.7
⇔x=(56.7÷1.05)
⇔x=54
Therefore she used (142-54)=88 pounds of type B coffee.

A building in a city has a rectangle base. The length of the base measures 70 feet less than three times the width. The perimeter of this base is 900 feet. What are the dimensions of the base?
Answer:
Width 130 ft and
Length 320 ft
Step-by-step explanation:
We are given;
Length of the rectangular base is 70 ft less than three times the width;Perimeter of the rectangular base is 900 ftWe are required to determine the dimensions of the rectangular base;
Assuming the width of the rectangular base is x ft
Then length will be (3x - 70) ft
But;
Perimeter = 2L + 2W
Thus;
900 ft = 2(3x-70) + 2(x)
900 ft = 6x -140 +2x
1040 = 8x
x = 130
Thus;
Width = 130 ft
Length = 3x -70 = 320 ft
Hence the dimensions of the rectangular base are width 130 ft and length 320 ft

Based on these data, is it better to describe the centers of distribution in terms of the mean or the median? Explain.
Mean for both bakeries because the data is symmetric
Mean, because the distribution is symmetric for both bakeries
Mean for Bakery A because the data is symmetric; median for Bakery B because the data is not symmetric
Mean for Bakery B because the data is symmetric; median for Bakery A because the data is not symmetric
Answer:
Mean for Bakery A because the data is symmetric; median for Bakery B because the data is not symmetric, as can be observed from the stem and leaf frequency plot.
Step-by-step explanation:
CALCULATIONS FOR BAKERY A
Considering the data for Bakery A
45 52 51 48 57 30 55 46
Calculating Mean for Bakery A
[tex]Mean=\frac{Sum\:of\:terms}{Number\:of\:terms}[/tex]
Sum of terms = 45 + 52 + 51 + 48 + 57 + 30 + 55 + 46 = 384
Number of terms = 8
As
[tex]Mean=\frac{Sum\:of\:terms}{Number\:of\:terms}[/tex]
[tex]Mean=\frac{302}{8}[/tex]
[tex]Mean=48[/tex]
Calculating Median for Bakery A
As the median is the middle number in a sorted list of numbers. So, to find the median, we need to place the numbers in value order and find the middle number.
As the data for Bakery A is
45 52 51 48 57 30 55 46
Ordering the data from least to greatest, we get:
30 45 46 48 51 52 55 57
As you can see, we do not have just one middle number but we have a pair of middle numbers, so the median is the average of these two numbers:
[tex]Median=\frac{\left(48+51\right)}{2}=\frac{99}{2}=49.5[/tex]
Getting a Plot and Leaf Plot for Bakery A
Plot and leaf plot is generally a unique table-like diagram which displays the frequency distribution of a data set. Plot and leaf plot is a visual aid that supports us in recognizing frequency classes and the center of the distribution where most of the data gets clustered around.Data for Bakery A in ascending order

Calculating Median for Bakery B
[tex]Mean=\frac{Sum\:of\:terms}{Number\:of\:terms}[/tex]
Sum of terms = 48 + 42 + 11 + 45 + 57 + 10 + 43 + 46 = 302
Number of terms = 8
[tex]Mean=\frac{302}{8}=37.75[/tex]
Calculating Median for Bakery B
[tex]Median=\frac{\left(43+45\right)}{2}=44[/tex]

Dakota bought 2 scarves and 1 hat for $13. Kristina bought 1 scarf and two hats for $14. What was the price for one hat and one scarf?
Answer:
The price for one hat was $5 and the price for one scarf was $4
Step-by-step explanation:
Let
x ----> the price for one scarf in dollars
y ----> the price for one hat in dollars
we know that
Dakota bought 2 scarves and 1 hat for $13
so
[tex]2x+y=13[/tex] ----> equation A
Kristina bought 1 scarf and two hats for $14
so
[tex]x+2y=14[/tex] ----> equation B
Solve the system by elimination
Multiply by -2 both sides equation B
[tex]-2(x+2y)=-2(14)[/tex]
[tex]-2x-4y=-28[/tex] ----> equation C
Adds equation A and equation C
[tex]2x+y=13\\-2x-4y=-28\\---------\\y-4y=13-28\\-3y=-15\\y=5[/tex]
Find the value of x
substitute the value of y in any equation
equation B
[tex]x+2(5)=14\\x=14-10\\x=4[/tex]
therefore
The price for one hat was $5 and the price for one scarf was $4
