Answer: 151
Step-by-step explanation:
In this situation we have two cones, the big cone with volume [tex]V_{big}[/tex] and the small cone with volume [tex]V_{small}[/tex].
Now, if we want to know the total volume [tex]V_{T}[/tex] we have to substract [tex]V_{small}[/tex] from [tex]V_{big}[/tex], but first we have to calculate each volume:
For the big cone:
[tex]V_{big}=\frac{\pi R^{2} H}{3}[/tex]
Where:
[tex]R=\frac{Diameter}{2}=\frac{8 in}{2}=4 in[/tex]
[tex]H=9 in[/tex]
Then:
[tex]V_{big}=\frac{\pi (4 in)^{2} 9 in}{3}[/tex]
[tex]V_{big}=150.79 in^{3}[/tex] Volume of big cone
For the small cone:
[tex]V_{small}=\frac{\pi r^{2} h}{3}[/tex]
Where:
[tex]r=\frac{diameter}{2}=\frac{1 in}{2}=0.5 in[/tex]
[tex]h=1 in[/tex]
Then:
[tex]V_{small}=\frac{\pi (0.5 in)^{2} 1 in}{3}[/tex]
[tex]V_{small}=0.261 in^{3}[/tex] Volume of small cone
Calculating the total volume:
[tex]V_{T}=V_{big}-V_{small}[/tex]
[tex]V_{T}=150.79 in^{3}-0.261 in^{3}[/tex]
Finally:
[tex]V_{T}=150.52 in^{3} \approx 151 in^{3}[/tex]
Answer:
151 in^3

You leave your ranch in South Texas to drive your cattle to the railroad in Abilene, Kansas. You have 2,000 head of cattle and 10 cowboys (not including you.) Along the trail, you are attacked by some cattle rustlers, the herd stampedes during a thunderstorm, and you have trouble finding water. As a result, when you get to Abilene, you have lost 10% of the herd. You sell the cattle in Abilene for $35 a head. You pay each of the cowboys $100 and the rest of the money is yours. How much did you make?
Answer:
You get $5727.27
Step-by-step explanation:
At the start, you have 2000
After you are attacked, stampeded and have trouble finding water, you have lost 10% of your cattle
2000 * 10% is 200
2000 - 200 is 1800
Multiply 1800 cattle by $35 per cow
1800 * $35 = $63000
10 cowboys + 1 (you) is 11 people
Divide $63000 by 11
63000 / 11 = $5727.27
You get $5727.27

Circle C has diameter AB. The coordinates of A are (5,1) and the coordinates of C are (6,10). Find the coordinates of B.
Answer:
(7, 19)
Step-by-step explanation:
We know that we are talking about circle C, which means that the center is point C. Since the diameter is AB, that means that AB goes through the center C and that center C is the midpoint of the segment AB.
Say the coordinates of B are (x, y). We can use the Midpoint Theorem to figure out B. The Midpoint Theorem states that for two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], the coordinates of the midpoint are: [tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex].
Here, our two points are A(5, 1) and B(x, y). Then, the midpoint is: [tex](\frac{5+x}{2} ,\frac{1+y}{2} )[/tex]. We already know the midpoint is C(6, 10), so we can just set 6 equal to [tex]\frac{5+x}{2}[/tex] and set 10 equal to [tex]\frac{1+y}{2}[/tex]:
6 = [tex]\frac{5+x}{2}[/tex] ⇒ 12 = 5 + x ⇒ x = 12 - 5 = 7
AND
10 = [tex]\frac{1+y}{2}[/tex] ⇒ 20 = 1 + y ⇒ y = 20 - 1 = 19
So, the coordinates of B is: (7, 19).
Hope this helps!
Answer:
(7 , 19)
Step-by-step explanation:
Centre is the midpoint of the diameter
C = Midpoint of AB
Let B: (x,y)
(6,10) = (x+5)/2, (y+1)/2
12 = x + 5
x = 7
20 = y + 1
y = 19
The sizes of seven exterior angles of an octagon are: 42, 110, 13, 67, 55, 11 and 53. What is the size of the eighth exterior angle?
Answer:
9 degrees.
Step-by-step explanation:
For ALL polygons, the exterior angles add up to 360 degrees.
Therefore the 8th exterior angle = 360 - (42+110+13+67+55+11+53)
= 360 - 351
= 9 degrees.
Answer:
9°
Step-by-step explanation:
Always some of exterior angle of any polygon is 360
42 + 110 + 13 + 67 + 55 +11 + 53 + x = 360
351 +x = 360
x = 360 - 351
x = 9
The equation x^2 - 3x + a = 0 has two roots. One root of the equation is 2. What is the other root?
a. -2
b. -1
c. 1
d. 3
The other root is 1, and the correct answer is: c. 1
The quadratic equation [tex]x^2 - 3x + a = 0[/tex] has two roots, and given that one of the roots is 2, we can use the fact that the sum of the roots is equal to the coefficient of the linear term (-b/a).
In this case, the linear term is −3x, so the sum of the roots is 3. Since we know one root is 2, the other root must be such that when added to 2, the sum equals 3.
Therefore, the other root is 3 − 2 = 1.
This demonstrates the application of the sum of roots formula in solving for the other root when one root is known. Hence, the correct answer is 1, which is option (c).

find the surface area of the composite 3D figure below. leave in terms of pi, numerical value only
Given:
The diameter of the cylinder = 34 m
So, the radius (r) = 17 m
The height (h) of the cylinder = 12 m
The slant height (l) of the cone = 20 m
To find the surface area of the given figure.
Surface area of the given fig = surface area of cylinder + surface area of the cone
Formula:
The surface area of the cylinder is [tex]2 \pi r(r+h)[/tex]
The surface area of the cone is [tex]\pi rs[/tex]
Now,
The surface area of the cylinder is given by
[tex]SA=2 \pi 17(17+12)[/tex]
[tex]=2 \pi 17(29)[/tex]
[tex]=2 \pi (493)[/tex]
[tex]SA=986 \pi[/tex]
The surface area of the cylinder is 986π m²
The surface area of the cone is given by
[tex]SA=\pi rs[/tex]
[tex]SA=\pi (17)(20)[/tex]
[tex]=340 \pi[/tex]
Thus, the surface area of the cone is 340π m²
The surface area of the composite figure is given by
Surface area = Surface area of cylinder + Surface area of cone
Substituting the values, we get;
[tex]SA=986\pi +340 \pi=1326 \pi \ m^2[/tex]
Thus, the surface area of the composite figure is 1326π m²

Draw the image of the figure after a rotation of 180° around O.
Answer:
Around o is the center point
The center point 0 is usually on a graph and you should use x axis if it doesn't say what axis o is. X + y are both 0 usually.
When you have 0 as a central point you are actually moving the shape at equality around just like you would with a pertractor.
So We have a same shape shown and you can do this by rotating the shape 180 so it looks upside down to how its shown originally or previously.
You then maneuver it around to the opposite graph diagonally opposite is most likely to be 180 degree.
So if it starts in x axis right side it will be in y axis diagonally to the left
You just have to show vertices or edges meet symmetrically from the 0 point like a mirror but also facing opposite direction as it has been rotated.
Step-by-step explanation:
The description of rotation of image of 180 degree around O is discussed below.
What is Transformation?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
Around o is the center point.
If it doesn't specify what the axis o is, use the x axis as the graph's centre point (0). Typically, (x+ y) are both 0.
The form at equality is actually moved around when 0 serves as the Centre, much like you would with a pertractor.
You can achieve this by turning the identical shape 180 degrees such that it appears upside down relative to how it was originally or previously displayed.
Hence, if it starts on the right side of the x axis, it will be on the left side of the y axis.
Thus, show how vertices or edges come together symmetrically from the origin, mirror-like, but also facing the other way because of rotation.

A picture is to be mounted on a board.
Show that the picture and the board are not mathematically similar.
A picture and the board it is mounted on are not mathematically similar because their corresponding sides do not have the same proportions, with the board generally having extra space around the picture that alters the length-to-width ratio. Additionally, artistic elements like tension and abstractness in images disrupt dimensional consistency that similarity requires.
Explanation:To show that a picture and the board it is mounted on are not mathematically similar, we must understand similarity in a mathematical context. For two figures to be similar, they must have the same shape but not necessarily the same size, meaning their corresponding angles are equal, and their corresponding sides are in proportion. When we mount a picture on a board, the picture itself has dimensions that are different from that of the board - the board is usually larger to provide a border or frame around the picture. Since the additional border provided by the board changes the overall dimensions, the two objects cannot be considered mathematically similar.
The concept of similarity also involves dimensional consistency. If the picture and the board were to be similar, the ratio of the length to width in the picture would have to be the same as that of the board. However, in most scenarios, a picture needs to be mounted with additional space around it, thus altering the ratio.
Additionally, from an artistic point of view, tension within a painting or an abstract representation might disrupt the dimensional consistency that mathematical similarity requires. Various factors such as perspective can create a visual illusion that skews perceived dimensions, making it impossible for the two to be similar. When a picture includes a pattern that has a specific repetition with variation, it does not satisfy the conditions of mathematical similarity when placed on a uniform board.
Functions f(x) and g(x) are shown below:

g(x) = x2 - 8x + 1
In which direction and by how many units should f(x) be shifted to obtain g(x)? (1 poi
Left by 4 units
Right by 4 units
Left by 8 units
Right by 8 units
Answer:
f(x) should shifted Right by 4 units to obtain g(x) ⇒ B
Step-by-step explanation:
Let us put g(x) in the form of g(x) = (x - h)² + k, where h is the the horizontal shift (x - h) to right, (x + h) to left and k is the vertical shift (k) up and (-k) down
In the quadratic function y = ax² + bx + c, h = [tex]-\frac{b}{2a}[/tex] and k = y at x = h
∵ g(x) = x² - 8x + 1
∵ a is the coefficient of x² and b is the coefficient of x
∴ a = 1 and b = -8
∵ h = [tex]-\frac{b}{2a}[/tex]
∴ h = [tex]-\frac{-8}{2(1)}=\frac{8}{2}[/tex]
∴ h = 4
∵ k = g(x) at x = h
- Substitute x by 4 in g(x) to find k
∴ k = (4)² - 8(4) + 1 = 16 - 32 + 1
∴ k = -15
- Substitute them in the form of g(x) = (x - h)² + k
∴ g(x) = (x - 4)² + (-15)
∵ h is the horizontal shift
∵ (x - h) means shift to right h units
∵ f(x) = x²
∵ g(x) = (x - 4)² + (-15)
- That means f(x) is shifted 4 units to the right
∴ f(x) should shifted right by 4 units to obtain g(x)

B. Right by 4 units

gallons of lemonade, how many
1-cup servings can they sell?
Oscar and Eli can sell 368 1-cup servings of lemonade because there are 16 cups in 1 gallon, and they have 23 gallons of lemonade.
Explanation:Calculating Servings of LemonadeOscar and Eli have prepared 23 gallons of lemonade and want to know how many 1-cup servings they can sell. First, we need to know the equivalent of gallons to cups. There are 16 cups in 1 gallon. Therefore, we multiply 23 gallons by 16 cups per gallon to find the total number of cups available:
23 gallons x 16 cups/gallon = 368 cups. Thus, they can sell 368 1-cup servings of lemonade.
To summarize the conversion:
1. Identify the conversion rate between gallons and cups (1 gallon = 16 cups).
2. Multiply the total gallons of lemonade by the conversion rate to get the total cups (23 gallons x 16 cups/gallon).

Danila breeds peregrine falcons. She recorded the breadth (in mm) of each egg and the mass (in g) of the falcon
chick that hatched from it.
After plotting her results, Danila noticed that the relationship between the two variables was fairly linear, so she
used the data to calculate the following least squares regression equation for predicting the mass of the chick
from the breadth of the egg:
y = -47 + 2x
What is the residual of a 29 g falcon chick who hatches from an egg with a breadth of 40 mm ?
Answer:
residual = - 4
Step-by-step explanation:
The residual is the difference between the actual mass of the falcon chick and the mass our regression line would have predicted.
residual = actual mass - predicted mass
actual mass = 29 grams
The predicted mass of 40 mm breadth of egg can be calculated by using the regression equation Danila came up with.
predicted mass
y = -47 + 2(40)
y = -47 + 80
y = 33 grams

Cylinder A
What is the ratio of the volume of Cylinder A to the volume of Cylinder B?
Given:
For cylinder A:
Radius = 3 unit
Height = 4 unit
For cylinder B:
Radius = 4 unit
Height = 3 unit
To find the ratio of the volume of cylinder A to the volume of cylinder B.
Formula
The volume of a cylinder is,
[tex]V = \pi r^{2} h[/tex]
where, r be the radius and
h be the volume of the cylinder.
Now,
For cylinder A
Putting, r = 3 and h = 4 we get,
Volume [tex]V_{A}[/tex] = [tex]\pi (3^{2} )(4)[/tex]
or, [tex]V_{A} = 36\pi[/tex]
For cylinder B
Putting, r = 4 and h = 3 we get
Volume [tex]V_{B}=\pi (4^{2} )(3)[/tex]
or, [tex]V_{B}= 48\pi[/tex]
Now,
The ratio [tex]\frac{V_{A} }{V_{B}} = \frac{36\pi}{48\pi}[/tex]
or, [tex]\frac{V_{A} }{V_{B}} = \frac{3}{4}[/tex]
Hence,
The ratio of the volume of Cylinder A to the volume of Cylinder B is [tex]\frac{3}{4}[/tex]. Option A
