Answer:
Cone A, Cone C, Cone B
Step-by-step explanation:
The volume of a cone is V=πr^2h/3 where V represents the volume, r represents the radius, and h represents the height.
That means the volume of cone A would be:
V = π * 5^2 * 6/3
V = π * 25 * 2
V = 50π
And the volume of Cone B would be:
V = π * 7^2 * 4/3
V = π * 49 * 4/3
V = 65.33π (about)
Lastly, the volume of Cone C would be:
V = π * 6^2 * 5/3
V = π * 36 * 5/3
V = 60π
65.33π > 60π > 50π
Therefore, Cone B has the largest volume, then Cone C, and, lastly, Cone A.

Amusement Park Buildings Part 1 There are two buildings that you want to have in the amusement park, but the size hasn’t been determined yet. Although you don’t know the specific dimensions, you do know the relationships between the sides. The first is the rectangular gift shop. You know that the length will be 20x+24 feet and the width will be 36x-20 feet. 1. Write the expression that represents the area of the gift shop, in terms of x. 2. Write the expression that represents the perimeter of the gift shop, in terms of x. 3. If the perimeter is going to be 176 feet, what are the dimensions of the building? Part 2 The next building is the gazebo that will be in the shape of a regular hexagon. (What does regular mean?) Each side will be 5x + 21 4. Write the expression that represents the perimeter of the gazebo, in terms of x. 5. If the perimeter is going to be 36 feet, what are the dimensions of the building?
Answer:
1. 56x - 480
2. 40x + 80
3. LENGTH = 72 feet, WIDTH = 66.4 feet
part 2: Regular means that all sides and angles are the same length
4. 6x
5. 216 feet
Step-by-step explanation:
(20x + 24) * (36x - 20)
56x - 480
2(20x + 24) + 2(36x - 20)
40x + 48 + 72 - 40
40x + 80
176 = 40x + 80
176 - 80 = 40x + 80 - 80
96 = 40x
96 / 40 = 40x / 40
2.4 = x
(20(2.4) + 24)
(36(2.4) - 20)
6(36)

Answer:
Option D.
The discriminat is equal to 24 which
Step-by-step explanation:
The quadratic equation is
-2x² + 3 = 0
Discriminat in quadratic equation tells us the number of solution a quadratic equation has.
For example, the quadratic equation
Ax² + bx + c = 0 will have a discriminat of b² - 4ac.
b² - 4ac is equal to the value of the discriminat and equal to the number of solutions the quadratic equation has.
In our question, we have -2x² + 3 = 0
A = -2
B = 0
C = 3
b² - 4ac = 0
Substitute the values into the above equation.

Area of rectangle ABCD is, 32 units²
And, Perimeter of rectangle is, 24 units
We have to given that,
A rectangle ABCD is shown in image.
And, Coordinates are,
A = (- 5, 5)
B = (- 1, 5)
C = (- 5, - 3)
D = (- 1, - 3)
Now, We can use the distance formula for finding the length and width of rectangle.
Lenght (AC) = √(- 5 + 5)² + (5 + 3)²
AC = √8²
AC = 8
Width (AB) = √(- 5 + 1)² + (5 - 5)²
AB = √16
AB = 4
Therefore, Area of rectangle ABCD is,
Area = Length × Width
Area = 8 × 4 = 32 units²
Perimeter of rectangle is,
P = 2 (Length + Width)
P = 2 (8 + 4)
P = 2 × 12

find the area of the isosceles triangle
Answer:
60
Step-by-step explanation:
→Before you use the formula to find the area of the isosceles triangle, you must find the height, and to do this, you can use the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
→We are given the hypotenuse, "c," as 13, and the leg is 5 (we split the base of 10 in half).
[tex]5^2+b^2=13^2[/tex]
[tex]25+b^2=169[/tex]
→Subtract 25 from both sides:
[tex]b^2=144[/tex]
→To get "b," by itself, take the square root of both sides:
[tex]\sqrt{b^2} =\sqrt{144}[/tex]
[tex]b = 12[/tex]
→Formula for area:
A = [tex]\frac{bh}{2}[/tex]
A = [tex]\frac{(10)(12)}{2}[/tex]
A = 60
The area of the isosceles triangle is 60 square units.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the triangle in a two-dimensional plane is called the area of the triangle.
The area is calculated by having the height of the triangle and the base of the triangle.
The height is calculated by using the Pythagorean theorem.
H² = P² + B²
13² = P² + 5²
P² = 169 - 25 = 144
P = √144 = 12 units
The perpendicular is the height of the triangle.
The area is calculated as:-
A = ( 1 / 2 ) x B x H
A = ( 1 / 2 ) x 10 x 12
A = 60 square units.

Activity
A pom-pom manufacturer makes each of its pom-poms with 35% white strands (w), 25% blue strands (b), and 40% red strands (r). If each pom-pom has a total of 80 strands, how many of strands of each color are needed to make a pair of pom-poms? In this activity, you’ll work through this pom-pom problem step by step.
Part E
Now solve for w, b, and r for a pair of pom-poms using the total number of strands you found in part D. Solve three proportions similar to the work you did in Part B. Show your calculations.
Answer:
w: 56
b: 40
r: 64
Step-by-step explanation:
A pair of pom-poms need: 80 × 2 = 160 (strands)
To make a pair of pom-poms:
w: 160 × 35% = 56 (strands)
b: 160 × 25% = 40 (strands)
r: 160 × 40% = 64 (strands)
28 white, 20 blue and 32 red strands are needed to make a pair of pom-poms.
What is percentage?Percentage is defined as ratio expressed as a fraction of 100.
Given that, total Strands = 80
∵white strands = 35%
w = 35%×80 =
w= 35/100×80
w = 28
∵blue strands = 25%
b = 25%× 80
b = 25/100× 80
b = 20
∵red strands = 40%
r = 40%× 80
r = 40/100× 80
r = 32
Thus, 28 white, 20 blue and 32 red strands are needed to make a pair of pom-poms.

C.Vertex: (-3,20)
D. Vertex: (3, 20)
E. x-intercepts: (-1,0). (7.0)
F. x-intercepts: (1.0), (-7,0)
The vertex and [tex]x-[/tex]intercepts of the graph of [tex]y= x^2 - 6x - 7[/tex] will be [tex](3,-16)[/tex] and [tex](7,-1)[/tex], respectively.
What are vertex and [tex]x-[/tex]intercepts of the graph?A vertex in a quadratic equation is the minimum or maximum point of the equation and an [tex]x-[/tex]intercept of a graph is the point at which the graph intersects the [tex]x-[/tex]axis.
Vertex form, [tex]y=a(x-h)^2+k[/tex]
We have,
[tex]y= x^2 - 6x - 7[/tex]
Now,
Find the [tex]x-[/tex]intercept and to find [tex]x-[/tex]intercept put [tex]y=0[/tex] ;
i.e. [tex]y= x^2 - 6x - 7[/tex]
[tex]0= x^2 - 6x - 7[/tex]
[tex]x^2 - 6x - 7=0[/tex]
Now using Mid-term split method find value of [tex]x[/tex];
[tex]x^2 - 7x+1x - 7=0[/tex]
[tex]x(x - 7)+1(x - 7)=0[/tex]
[tex](x - 7)(x +1)=0[/tex]
[tex](x - 7)=0[/tex]⇒[tex]x=7[/tex]
[tex](x +1)=0[/tex]⇒[tex]x=-1[/tex]
So, these are the [tex]x-[/tex]intercept [tex](7,-1)[/tex] of the expression.
Now find the vertex using the above given formula;
[tex]y=a(x-h)^2+k[/tex]
Rewrite in vertex form
[tex]y= x^2 - 6x - 7[/tex]
Add and subtract [tex](-3)^2[/tex] in given expression;
[tex]y= x^2 - 6x + (-3)^2 -7 - (-3)^2[/tex]
[tex]y = x^2 - 6x + 9 -7 - 9[/tex]
[tex]y = x^2 - 6x + 9 -16[/tex]
Now convert quadratic part of equation in [tex](a-b)^2[/tex];
[tex]y = (x-3)^2-16[/tex]
Now compare it with [tex]y=a(x-h)^2+k[/tex]
We get, [tex]h=3,\ k=-16[/tex]
So, these are the vertex [tex](3,-16)[/tex] of expression.
Hence, we can say that the vertex and [tex]x-[/tex]intercepts of the graph of [tex]y= x^2 - 6x - 7[/tex] will be [tex](3,-16)[/tex] and [tex](7,-1)[/tex], respectively.

I put 17 there as [tex]T_4[/tex] because I want 3 consecutive elements. Let A is the sum of them.
[tex]T_1+T_2+T_3 = A[/tex]
17
[tex]T_5+T_6+T_7 = A[/tex]
[tex]T_8+T_9+T_{10} = A[/tex]
[tex]T_{11}+T_{12}+T_{13}=A[/tex]

A voter polling research group determined that 30% of the voters in a county would vote for the democratic candidate with a ±4% margin of error. If they anticipate only 12,000 people will turn out to vote in this election, which would represent the lowest possible number of voters for the democratic candidate.
Answer:
Minimum number of voters for the democratic candidate would be 3120 voters.
Step-by-step explanation:
Total number of people turning out to vote = 12,000
Percentage of votes a democratic would get = 30%
Which means that it is expected that a democratic candidate will get: 30/100 · 12,000 = 3600 votes
However, the polling may have an error of +4% to -4%
Which means that the votes a democratic candidate will get will range from 30%+4% = 34% to 30%-4%= 26% of the total people who turn out to vote
Minimum number of voters can be determined by taking 26% of the total people who turn out to vote:
Minimum number of votes = 26/100 · 12,000 = 3120

The range of the Morning box plot is 1 less than the range of the Afternoon box plot.
The range of the Morning box plot is 1 more than the range of the Afternoon box plot.
The range of the Morning box plot is 2 less than the range of the Afternoon box plot
Answer:
The range of the Morning box plot is the same as the range of the Afternoon box plot.
Step-by-step explanation:
Data provided in the question
Number line = 0 to 16
Morning whiskers range = 3 to 15
Box range = 5 to 12
Line divided = 8
Afternoon whiskers range = 4 to 16
Box range = 8 to 15
Line divided = 14
