How many vertices does a dodecahedron have
Answer:
20
Step-by-step explanation:
A dodecahedron is a three-dimensional figure made out of 12 regular pentagons. It resembles a soccer ball, just more rough on the edges.
So, it has 12 faces made out of regular pentagons. Each summit/vertex is a meeting point for 3 different pentagons.
So, you can easily calculate the number of vertices:
How many pentagon vertices in total?
12 pentagons with 5 vertices / pentagon = 60 vertices in total
But each vertex meets with two others... so you have to divide the number of total vertices by 3... so 60 / 3 = 20.
Answer:
12 faces

Jimmy is trying to dive down and touch the bottom of the pool. On his first try he makes it 1/3 of the way to the bottom. On his second try he makes it 3/5 of the way to the bottom. Jimmys second dive was deeper than his first dive by what fraction of the pool?
Answer:
Jimmy's second dive was [tex]\frac{4}{15}[/tex] of the pool deeper than the first one
Explanation:
We are given that:
First dive was [tex]\frac{1}{3}[/tex] of the way to the bottom
Second dive was [tex]\frac{3}{5}[/tex] of the way to the bottom
We know that the second dive was deeper than the first one since [tex]\frac{3}{5} > \frac{1}{3}[/tex]
To know how much deeper the second dive was compared to the first one, we will simply subtract the depth of the first dive from that of the second one
Therefore:
The second dive was [tex]\frac{3}{5} - \frac{1}{3} = \frac{9}{15} - \frac{5}{15} = \frac{4}{15}[/tex] of the pool deeper than the first one
Hope this helps :)
Final answer:
Jimmy's second dive was 4/15 of the pool deeper than his first dive, calculated by finding a common denominator and subtracting the fractions representing the depth of each dive.
Explanation:
Jimmy's second dive was 3/5 of the way to the bottom of the pool, which is deeper than his first dive at 1/3 of the way. To find out how much deeper the second dive was compared to the first, we subtract the two fractions:
Second dive - First dive = 3/5 - 1/3
To subtract fractions, they must have a common denominator. Multiplying top and bottom of 3/5 by 3 and 1/3 by 5 gives us:
9/15 - 5/15 = 4/15
Therefore, Jimmy's second dive was 4/15 of the pool deeper than his first dive.

Final answer:
To calculate the number of different combinations of adult and children's tickets that would total $100, we can set up an equation: 5x + 3y = 100. We can find possible values of 'x' and 'y' that satisfy the equation. There are 6 different combinations of adult and children's tickets that would have totaled $100.
Explanation:
To calculate the number of different combinations of adult and children's tickets that would total $100, we can set up an equation:
5x + 3y = 100
Where 'x' represents the number of adult tickets and 'y' represents the number of children's tickets. We need to find whole number solutions for 'x' and 'y'.
We can start by finding the possible values of 'x' and 'y' that satisfy the equation and add up to $100. The possible combinations are:
x = 0, y = 33
x = 5, y = 31
x = 10, y = 29
x = 15, y = 27
x = 20, y = 25
x = 25, y = 23
Therefore, there are a total of 6 different combinations of adult and children's tickets that would have totaled $100.
What is the product?

Answer:
1/4 bag for each batch.
Step-by-step explanation:
Start with 4 bags. If the cake requires 1/4 bag, then 3 3/4 bags of flour are left over for the cookies. That's rather a nice number when you are dealing with 15 batches of cookies.
Start by changing the 3 3/4 into a decimal.
3 3/4 = 3.75
Now divide 3.75 by 15
3.75 / 15 = 0.25 bags which is 1/4 bag. You only have to come up with one value so this one will do.
A ceiling light has a cross-section in the shape of a parabola. The parabola is 24 cm wide and 9 cm deep. The lightbulb is located at the focus of the parabola. How far from the vertex is the lightbulb?
Answer:
4 cm
Step-by-step explanation:
The equation of a parabola with its vertex at the origin can be written as ...
y = 1/(4p)x^2
The problem statement tells us that one point on the parabola is (x, y) = (12, 9). We can put these values into the equation and solve for p, the distance from the focus to the vertex.
9 = 1/(4p)(12^2)
9×4/144 = 1/p = 1/4 . . . . . . . . multiply by the inverse of the coefficient of 1/p
Then p = 4, and the bulb is 4 cm from the vertex.

Step-by-step explanation:
[tex]p_1:~~y = x^2+2\\p_2:~~y = 3x^2+2\\ \\ V{p_1} = \Big(-\dfrac{b}{2a}, -\dfrac{\Delta}{4a}\Big) = \Big(-\dfrac{0}{2}, -\dfrac{0^2-4\cdot 2}{4}\Big) = \Big(0,2\Big) \\ \\ Vp_2 = \Big(x_V, -\dfrac{\Delta}{4a}\Big) = \Big(0, -\dfrac{0^2-4\cdot 3 \cdot 2}{4\cdot 3}\Big) = \Big(0,2\Big) \\ \\ \\ \text{The distance is }0,~~\text{Because the vertices are equal.}[/tex]
The distance between the vertices of the graphs is 0.
Explanation:The distance between the vertices of the graphs corresponding to y = x2 + 2 and y = 3x2 + 2 can be found by finding the x-coordinates where the graphs intersect. To do this, we set the two equations equal to each other:
x2 + 2 = 3x2 + 2
Subtracting 2 from both sides gives: x2 = 3x2
Subtracting x2 from both sides gives: 0 = 2x2
Dividing both sides by 2 gives: 0 = x2
This equation has only one solution: x = 0. Therefore, the distance between the vertices of the graphs is 0.

4=$17.60
1=$17.60/4
1=$4.40
Hole this helps :)
The unit price of a padlock, when rounded to the nearest cent, is $4.40 per padlock.
To calculate the unit price of a padlock, you'll need to determine the cost per individual padlock within a pack. In this scenario, you have a pack of 4 padlocks that costs $17.60. To find the cost of a single padlock, you can use the following formula:
Unit Price = Total Cost / Number of Padlocks
In this case:
Total Cost = $17.60
Number of Padlocks = 4
Now, let's calculate the unit price:
Unit Price = $17.60 / 4 padlocks
Unit Price = $4.40 per padlock
So, the unit price of each padlock is $4.40 when rounded to the nearest cent.
Understanding the unit price is essential for making informed purchasing decisions. It allows you to compare prices and determine whether buying in bulk (in this case, a pack of 4 padlocks) is more cost-effective than purchasing items individually.
In summary, the unit price of a padlock is $4.40 per padlock when rounded to the nearest cent. This information helps consumers assess the value of buying items in larger quantities and ensures they get the best deal for their money.

To take a taxi it costs $3.00 plus an additional $2.00 per mile traveled. You spent exactly $20 on a taxi, which includes the $1 tip you left. How many miles did you travel?
This is a basic algebraic word problem. Make x equal the miles you traveled. multiply that by 2 and add the 3 initial dollars, then add the one dollar tip, finally make all this equal to 20. So your equation should look like this:
2x + 3 + 1 = 20
add the 3 and 1:
2x + 4 =20
move the 4 to the right side:
2x = 16
devide both sides by 2:
x = 8
So you traveled 8 miles.
Rhonda has $1.35 in nickels and dimes in her pocket. If she has six more dimes than nickels, which equation can be used to determine x, the number of nickels she has?
A: 0.05+0.10(6x)=1.35
B: 0.05(x+6)+0.10x=1.35
C: 0.05x+0.10(x+6)=1.35
D: 0.15(x+6)=1.35
Answer:
Option C. 0.05x+0.10(x+6)=1.35
Step-by-step explanation:
Remember that
1 nickel=$0.05
1 dime=$0.10
Let
x-----> the number of nickels
y----> the number of dimes
we know that
0.05x+0.10y=1.35 -----> equation A
y=x+6 ----> equation B
substitute equation B in equation A and solve for x
0.05x+0.10(x+6)=1.35
The correct equation that can be used to determine x, the number of nickels Rhonda has, is 0.05x + 0.10(x+6) = 1.35, which is option C from the ones presented.
Explanation:In this question, we are asked to find the equation that we can use to determine the number of nickels, represented by 'x', Rhonda has. Given that Rhonda has six more dimes than nickels, the cost of dimes in Rhonda's pocket can be represented by 0.10*(x+6) because each dime is worth $0.10 and she has six more dimes than nickels. Similarly, the cost of nickels in Rhonda's pocket could be represented as 0.05*x because each nickel is worth $0.05. As the total amount of money Rhonda has is $1.35, the two amounts should sum up to 1.35. Hence, the correct equation would be 0.05x + 0.10(x+6) = 1.35, so the answer is option C.

A solid right pyramid has a square base. The base edge length is 2 cm longer than the height of the pyramid.If the height is 6 cm, the volume of the pyramid is ____cm3.
Answer:
The volume of the pyramid is 128 cm³
Step-by-step explanation:
* Lets revise the volume of the pyramid
- The pyramid has one base and the number of side faces depends
on the number of sides of the base
- The volume of any pyramid is 1/3 × Area of its base × its height
* Lets solve the problem
- The pyramid has a square base
- It has four side faces all of them are triangles
- It has five vertices and eight edges
- The area of the base = s², where s is the length of the side of
the square
- The volume of the pyramid is 1/3 × s² × h, where h is the height
of the pyramid
- The base edge length of the base is 2 cm longer than the height
of the pyramid
- The height of the pyramid is 6 cm
∵ The length of the edge of the base is 2 cm longer than the
height of the pyramid
∵ The height of the pyramid (h) = 6 cm
∴ The edge length of the base = 6 + 2 = 8 cm
- The area of the base = s²
∵ s = 8 cm
∴ The area of the base (s²) = 8² = 64 cm²
- The volume of the pyramid = 1/3 × s² × h
∴ Its volume = 1/3 × 64 × 6 = 128 cm³
* The volume of the pyramid is 128 cm³
The correct answer is:
128 cm^3

Answer:
B
C
A
Step-by-step explanation:
Find the value of x in each equation then compare the solutions from the least to the greatest
In A
5( x-6)+3x=3/4(2x-8) ------------Open brackets
5x-30+3x=3/2x-6
5x+3x-30=3/2x-6
8x-3/2x=-6+30---------------collect like terms
16x-3x=48
13x=48-----------------dived both sides by 13
x=48/13 = 3.7
In B
2.7(5.1x+4.9)=3.2+28.9-------------open bracket
13.77x+13.23=32.1
13.77x=32.1-13.23---------------collect like terms
13.77x=18.87
x=18.87/13.77----------------------divide both sides by 13.77
x=1.37
In C
5(11x-18)=3(2x+7)--------------------open brackets
55x-90=6x+21
55x-6x=21+90-----------------------collect like terms
49x=111----------------------------------divide both sides by 49 to get x
x=111/49 = 2.27
From the solutions, the least value of x is in B, then C ,and finally A
Equation B:[tex]\(x \approx 1.371\)[/tex]
Equation C:[tex]\(x \approx 2.2653\)[/tex]
Equation A: [tex]\(x = \frac{48}{13}\)[/tex]
Order from least to greatest: B, C, A.
To solve each equation, let's start by simplifying each side of the equation step by step.
Equation A:[tex]\(5(x-6) + 3x = \frac{3}{4}(2x - 8)\)[/tex]
Step 1: Distribute the numbers:
[tex]\(5x - 30 + 3x = \frac{3}{4}(2x) - \frac{3}{4}(8)\)[/tex]
Step 2: Combine like terms:
[tex]\(8x - 30 = \frac{3}{2}x - 6\)[/tex]
Step 3: To get rid of the fraction, multiply both sides by 2:
(16x - 60 = 3x - 12)
Step 4: Move all (x) terms to one side by subtracting (3x) from both sides:
(16x - 3x - 60 = -12)
Step 5: Combine like terms:
(13x - 60 = -12)
Step 6: Add 60 to both sides to isolate (x):
13x = 48
Step 7: Divide both sides by 13 to solve for (x):
[tex]\(x = \frac{48}{13}\)[/tex]
Equation B: 2.7(5.1x + 4.9) = 3.2 + 28.9
Step 1: Distribute the number:
13.77x + 13.23 = 32.1
Step 2: Move the constant to the other side by subtracting 13.23 from both sides:
13.77x = 18.87
Step 3: Divide both sides by 13.77 to solve for (x):
x ≈ 1.371
Equation C: (5(11x - 18) = 3(2x + 7)
Step 1: Distribute the numbers:
55x - 90 = 6x + 21
Step 2: Move all (x) terms to one side by subtracting (6x) from both sides:
55x - 6x - 90 = 21
Step 3: Combine like terms:
49x - 90 = 21
Step 4: Add 90 to both sides to isolate (x):
49x = 111
Step 5: Divide both sides by 49 to solve for (x):
x ≈ 2.2653
Now, let's order these solutions from least to greatest:
[tex]\(x= 1.371\)[/tex] (from Equation B)
[tex]\(x = 2.2653\)[/tex] (from Equation C)
[tex]\(x = \frac{48}{13}\)[/tex] (from Equation A)
So, the order from least to greatest based on their solutions is Equation B, Equation C, and then Equation A.

Determine the slope and the y-intercept
The slope of the two equations can be found based on what the number in front of the x is, this term is also called the coefficient.
The y-intercept is in the form of b and is substituted normally by a positive or negative integer.
Slope: 1/4 and 2
Y-intercept: 3 and 10
You must graph these, for this problem I have provided one for you.
Determining the solution
Since this problem requires you to find the solution based on the graph you must graph the two lines and the solution is the point in which the two lines intersect.
Based on the graph I have provided for you, we can determine that the solution is (-4,2)
Checking your work
In math it's very important to check your work: plug in the solution and if it is a perfect math then the solution is correct.
[tex]\frac{1}{4} (-4)+ 3 = 2[/tex]
The solution applies to the first equation, however we must now check for the second equation.
[tex]2(-4) + 10 = 2[/tex]
The solution also applies to the second equation, so we now know that this solution is correct.

They have one overlap (a).
Katie can expect to win 4 out of 26 games.
Nathan can expect to win 3 out of 26 games.
Since Katie has more distinct letters, she has the advantage, so it is not a fair game.
If the length of side a is 16 centimeters, the length of side b is 10 centimeters, and m = 42°, what is the measure of ? Round your answer to two decimal places.
Answer:Substitute the given values in the Law of Sines and find that the measure is 24.72°
The measure of the missing angle is approximately 113.28°.
Assuming that the missing angle is opposite to side c, we can use the Law of Sines to find the measure of the missing angle. The Law of Sines states that for any triangle ABC:
a/sin(A) = b/sin(B) = c/sin(C)
Substituting the given values, we have:
16/sin(42°) = 10/sin(B) = c/sin(C)
Solving for sin(B), we get:
sin(B) = 10*sin(42°)/16 ≈ 0.4182
Using the inverse sine function, we can find the measure of angle B:
B ≈ sin⁻¹(0.4182) ≈ 24.72°
Now, we can use the fact that the angles of a triangle add up to 180° to find the measure of the missing angle:
A + B + C = 180°
A + 42° + 24.72° = 180°
A ≈ 113.28°
Therefore, the measure of the missing angle is approximately 113.28°.

A copy machine depreciates at the rate of 15% each year. If the original cost of the copy machine was $20,000, what is the approximate value of the machine at the end of 3 years?
$12,282.5 (20000x0.85x0.85x0.85)
The value of the copy machine depreciates at a rate of 15% each year. After calculating the depreciated value for 3 consecutive years, the copy machine that initially cost $20,000 is worth approximately $12,282.50 after 3 years.
Explanation:The original cost of the copy machine is $20,000. Given that the copy machine depreciates, or loses value, at a rate of 15% each year, we need to calculate the value of the copy machine each year for 3 years by subtracting 15% of its current value.
In the first year, the value of the copy machine would be $20,000 - (15% of $20,000) = $20,000 - $3,000 = $17,000. In the second year, we will take 15% off $17,000, so the value will be $17,000 - (15% of $17,000) = $17,000 - $2,550 = $14,450. Finally, in the third year, we will take 15% off $14,450, so the final value is $14,450 - (15% of $14,450) = $14,450 - $2,167.50 = $12,282.50. So, the approximate value of the machine at the end of 3 years is $12,282.50.Learn more about Depreciation here:https://brainly.com/question/17827672

Answer:
B. <Q = <R
Step-by-step explanation:
Angles are related to their intercepted arcs. An intercepted arc is found by finding the arc segment on a circle whose endpoints connect with the segments that make up an angle.
In this case, TQ and SQ make up <Q, so TS is the intercepted arc of <Q. However, TR and SR make up angle <R as well, making TS the intercepted arc of <R as well.
This means that because the angles share an intercepted arc, they are congruent.
