Select the figure with no line symmetry and a rotational symmetry angle of 180 degrees.
A.
B.
C.
D.
In the given figures figure C has no line of symmetry. Hence, option C is correct.
The line of symmetry is an imaginary line that divides an object into two equal and identical halves.
It is a reflectional symmetry, meaning that each point on one side of the line corresponds to an identical point on the other side.
This line can be vertical, horizontal, or even diagonal, depending on the shape or object being considered.
The line of symmetry is an important concept in geometry and can be found in various symmetrical objects like letters, shapes, and even faces.
If we rotate Figure C with respect to any axis we don't get an identical shape.
Therefore,
Figure C has no line of symmetry.

About how much would it cost to buy 18 CD/MP3 players?
Electronics Prices
DATA
CD player
$74.00
MP3 player $99.00
CD/MP3 player : $199.00
AM/FM radio : $29.00
In 2-15, estimate each product.
Answer:
the answer would be $3,582 dollars i hope u geta good grade and your welcome :3
Answer: The cost would be $1782 and $3582 respectively.
Step-by-step explanation:
Since we have given that
Number of MP3 players = 18
Number of CD/MP3 = 18
Cost of each MP3 = $99.00
Cost of each CD/MP3 = $199.00
So, the Cost of 18 MP3 would be
[tex]18\times 99\\\\=\$1782[/tex]
And, the cost of 18 CD/MP3 would be
[tex]199\times 18\\\\=\$3582[/tex]
Hence, the cost would be $1782 and $3582 respectively.
10. Elaine is buying cube shaped blocks to add to her mantle as decoration. She needs the dimensions of the cubes to be less than 5 inches along each edge. Which of the following would work according to the size she needs? ece of ch shows to find ? A. Cubes with a volume of 216 in.3 B. Cubes with a volume of 125 in.3 C. Cubes witha volume of 64 in.3 D. Both B and C would work
Answer: OPTION C.
Step-by-step explanation:
The volume of a cube can be calculated with the following formula:
[tex]V=s^3[/tex]
Where "s" is the length of each edge of the cube.
Solving for "s":
[tex]s=\sqrt[3]{V}[/tex]
Let's check each option to find which volume would work according to the size she needs:
A. Substitute [tex]V=216in^3[/tex] into [tex]s=\sqrt[3]{V}[/tex], then:
[tex]s=\sqrt[3]{216in^3}=6in[/tex]
B. Substitute [tex]V=125in^3[/tex] into [tex]s=\sqrt[3]{V}[/tex], then:
[tex]s=\sqrt[3]{125in^3}=5in[/tex]
C. Substitute [tex]V=64in^3[/tex] into [tex]s=\sqrt[3]{V}[/tex], then:
[tex]s=\sqrt[3]{64in^3}=4in[/tex]

b) Graph the two equations to find the point of intersection.
c) What does the point of intersection represent?
d) Which plan should Charlene choose if she estimates that she will use her phone
10 h per month? 6 h per month?
Answer:
See explanation
Step-by-step explanation:
Let x be the number of minutes Charlene uses her phone per month and $y be the charge (in dollars) for x minutes of usage the phone.
A. Cell Plus gives unlimited minutes for $50/month. This paln doesn't depend on time, so
[tex]y=50[/tex]
A1 Cell offers a $40 monthly fee, plus $0.05/min for any time over 300 min per month, then
[tex]y=40+0.05(x-300)\\ \\y=40+0.05x-15\\ \\y=25+0.05x[/tex]
B. Attached diagram shows the graphs of these two functions.
C. The point of intersection is (500,50) and it represents the number of minutes x=500 when to plans have the same charges.
D. 10 hours = 600 minutes.
Cell plus charge = $50
A1 Cell charge [tex]=25+0.05\cdot 600=\$55[/tex]

Decrease £28 by 7%
Increase £28 by 7%
Answer:
decrease = 26.04
increase = 29.96
Step-by-step explanation:
Decrease of £28.00 by 7% = £28 -(7% of 28)
= £28 - (0.07 × 28)
= £28 - 1.96
= £26.04
Increase of £28 by 7% = £28 +(7% of 28)
= £28 +(0.7 × 28)
= $28 + 1.96
= £29.96
Decrease £28 by 7% would be £26.04
and increase £28 by 7% would be £29.96

D. It is not a whole number.

A
41 is not divisible by any number other than 1 and itself so it is prime and not composite and obviously 41 is a whole number so BCD are eliminated
Answer:
A. 41 is a prime number.
Step-by-step explanation:
Since we know that 8x5= 40 and 8x6= 48, it is not a prime number.
And even if you divide any number by 41, you won't get a whole number answer. So that is why 41 is a prime number.

Joyce paid 63.00 for an item at the store that was 65 percent off the original price . What was the original price
Answer:
100 % - 65% = 35%
this means that 63.00 is 35% the original price
cross multiply:
$63 35%
$x 100%
100 * 63 = 6300
------------ ---------- = $180
35 35
original price $180
The original price, 100% of an item at the store is $180.00.
What is a percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
For the given situation,
Amount paid by Joyce = $63.00
Consider the original price be 100%
65 percent off the original price = [tex]100 - 65[/tex]
⇒ [tex]35[/tex]
So, 35% of an item is $63.00
The original price 100% can be calculated as
⇒ [tex]\frac{63(100)}{35}[/tex]
⇒ [tex]\frac{63100}{35}[/tex]
⇒ [tex]180[/tex]
Hence we can conclude that the the original price, 100% of an item at the store is $180.00.

The area of a rectangle is 48 cm² and the length of the rectangle is 8 cm longer than the width.

w(w+8)=48
w + 8 = 48
8w = 48
w + 8w = 48
Answer: A
Step-by-step explanation: You know multiplying will be involved, so B can automatically be removed. It states that the length is 8 cm longer. You know absolutely nothing about the width, so the variable of w can be given for the width. You also know the length will be 8 cm longer, of w+8. w and w+8 will be multiplied, which gives you w(w+8).

D : 42
Answer:
The answer would be 43 because 62.25-18.92=43.34 therefore it would be rounded down the nearest whole number
Answer:
A
Step-by-step explanation:
First round both numbers to the nearest whole number which would be 62-19. Now calculate. The answer is 43
What does 4 - (-19) equal?
Answer:
23
Step-by-step explanation:
Whenever you subtract a negative number, you treat it as if you're adding a positive number.
For example:
-5-(-5) becomes -5+5, which is 0.
So, 4-(-19) becomes 4+19, which is 23.

Suppose you read 1000 pages a month. How long would take you to finish reading 1million pages?
Final answer:
To finish reading 1 million pages while reading 1000 pages a month, it would take the student 1000 months.
Explanation:
To calculate how long it would take to finish reading 1 million pages, we need to find the number of months required. Since the student reads 1000 pages a month, we can set up a proportion:
1000 pages / 1 month = 1 million pages / x months
Cross-multiplying gives:
1000x = 1 million
Dividing both sides by 1000:
x = 1000 months
Therefore, it would take the student 1000 months to finish reading 1 million pages.

4 people can dig a hole in 3 hours. How long does it take 9 people.
Answer:
9 people is 9/4 = 2.25 times more people than 4 people. So, they can do it faster. 3 hours/2.25 = 1.33 hours 1.33 hours x 60 minutes/hour = 80 minutes
Step-by-step explanation:
Answer: 1 hour 20 minutes
Step-by-step explanation:
Let's figure out how long it would take 1 person to dig the hole and then divide that number by 9 (since they are sharing the workload).
[tex]\dfrac{1}{4}x=3\qquad \implies \qquad x = 12\quad \text{It takes 12 hours for 1 person}\\\\\\\dfrac{12\ \text{(for 1 person)}}{9\ \text{(people)}}\quad =1\dfrac{1}{3}\quad =\large\boxed{1\ hour\ 20\ minutes}[/tex]

Step-by-step explanation:
we have that
[tex]f(x)=\frac{1}{2}x[/tex]
[tex]f^{-1}(x)=2x[/tex]
Part 1) Find f(2)
For x=2
substitute the value of x in f(x)
[tex]f(2)=\frac{1}{2}(2)[/tex]
[tex]f(2)=1[/tex]
Part 2) find [tex]f^{-1}(1)[/tex]
For x=1
Substitute the value of x in [tex]f^{-1}(x)[/tex]
[tex]f^{-1}(1)=2(1)[/tex]
[tex]f^{-1}(1)=2[/tex]
Part 3) Find [tex]f^{-1}(f(2))[/tex]
we know that
[tex]f(2)=1[/tex] -----> see part 1)
so
[tex]f^{-1}(f(2))=f^{-1}(1)[/tex]
we have that
[tex]f^{-1}(1)=2[/tex] -----> see part 2)
therefore
[tex]f^{-1}(f(2))=2[/tex]

Point G is the midpoint of RH. It is known that RG = 7x - 23 and RH = 6x + 90. Find the value of GH
Answer:
GH = 96
Step-by-step explanation:
Since G is at the midpoint of RH then RG = SH and
GH = 7x - 23
Thus
RG + GH = RH ← substitute values
7x - 23 + 7x - 23 = 6x + 90
14x - 46 = 6x + 90 ( subtract 6x from both sides )
8x - 46 = 90 ( add 46 to both sides )
8x = 136 ( divide both sides by 8 )
x = 17
Hence
GH = 7x - 23 = (7 × 17) - 23 = 119 - 23 = 96
Answer:
96
Step-by-step explanation:
Drawing a picture helps to think this problem through. 2(7x-23)=6x+90 by midpoint theorem. Solve this equation.
14x-46=6x+90
8x=136
x=17
Substitute x in the equation for RG. 7(17)-23.
7x17=119
119-23=96
