Volume of cone is 1272.34502 [tex]cm^{3}[/tex]
What is volume of cone?The volume of a cone is defined as the amount of space or capacity a cone occupies. The volume of a cone formula is given as one-third the product of the area of the circular base and the height of the cone.
Given
Diameter of cone = 18 cm
Radius of cone = [tex]\frac{18}{2}[/tex] = 9 cm
Height of cone = 15 cm
Volume of cone = [tex]\frac{1}{3} \pi r^{2} h[/tex]
= [tex]\frac{1}{3} \pi (9)^{2} (15)[/tex]
= 1272.34502 [tex]cm^{3}[/tex]
Hence, volume of cone is 1272.34502 [tex]cm^{3}[/tex]

aisha and jordan start by making a floor plan for their treehouWhich revision of these two sentences best shows that the coach blowing the whistle happened first?
The referee blew the whistle. The team ran onto the field.
Before the team ran onto the field, the referee blew the whistle.
The referee blew the whistle, but the team ran onto the field.
The referee blew the whistle because the team ran onto the field.
While the team ran onto the field, the referee blew the whistle.se. they decide to build a porch on one side of the treehouse
Answer: Statements 1 and 2 shows that the coach blowing the whistle happened first.
Step-by-step explanation: The coach blowing the whistle as the first event can be seen only from statements 1 and 2 only.
From statement 1, "the referee blew the whistle" was followed by "the team ran onto the field."
From statement 2, "before the team ran onto the field" shows clearly that one event took place "BEFORE" the one being reported and the one that occurred before this one was "the referee blew the whistle."
Statement 3 which is "the referee blew the whistle, BUT..." indicates that the whistle was meant to prevent the team from from running onto the field. So if the referee blew the whistle, but the team ran onto the field, it means the whistle blowing was not supposed to make them run onto the field.
Statement 4, which states that "the referee blew the whistle BECAUSE the team ran onto the field" indicates that, the reason for blowing the whistle was because the team ran onto the field which clearly shows that the team ran onto the field first before the referee blew the whistle.
Statement 5, "WHILE the team ran onto the field..." clearly shows that both events took place at the same moment, and so the referee blowing the whistle could not have occurred first.
Find values that make the sentence correct 1). 6/8=x/12=x/16
Answer:
x = 9 and 12
Step-by-step explanation:
6/8 = x/12 = x/16
Simplify
3/4 = x/12 = x/16
Multiply 3/4 by 3/3 (does nothing but changes the number)
9/12 = x/12
x = 9
Multiply 3/4 by 4/4 ( also does nothing)
12/16 = x/16
x = 12
There is no values of X that will make the expression correct

Keith is making a tomato soup recipe that requires 4/5 of a pound of tomatoes but he only has 3/4 of a pound of tomatoes. What fraction of the recipe can Keith make with the amount of tomatoes he has? (I'm lazy...someone help me out?)
Answer:
15/16 tomato soup
Step-by-step explanation:
his problem can be solved using the principle of proportionality or rule three.
A tomato soup recipe that requires 4/5 of a pound of tomatoes, which means that one unit of tomato soup is produced.
So how many units is produced with the amount of 3/4 of a pound of tomato.
Pound Tomato Tomato soup
4/5 1
3/4 x
then x equals:
x = (3/4*1)/(4/5)
x = 0.9375
x = 15/16 tomato soup
Which means that they are that amount of tomato produces 15/16 tomato soup.

Elena, Jada, and Lin enjoy playing basketball during recess. Lately, they have been practicing free throws. They record the number of baskets they make out of 10 attempts. Here are their data sets for 12 school days.
Elena: 4 5 1 6 9 7 2 8 3 3 5 7
Jada: 2 4 5 4 6 6 4 7 3 4 8 7
Lin: 3 6 6 4 5 5 3 5 4 6 6 7
Calculate the mean number of baskets each player made, and compare the means. What do you notice?
Answer:
They all have the same mean of 5
Step-by-step explanation:
first add up all the numbers in each data set separately and then divide by the total number (12) to find the mean for example
Elena: 4+5+1+6+9+7+2+8+8+3+3+5+7= 60
60 divided by 12 equals 5

y=3(x-2)(x+1)(x-4) find all the zeros of the function
Answer:
All of the zeros would be 2, -1 and 4
Step-by-step explanation:
When you set each of the factors equal to zero solve for x. The only one you can't is 3 because [tex]3\neq 0\\[/tex]
Final answer:
The zeroes of the function y = 3(x-2)(x+1)(x-4) are x = 2, x = -1, and x = 4.
Explanation:
The question asks to find all the zeros of the function y = 3(x-2)(x+1)(x-4). A zero of the function is a value of x that makes the function equal to zero. To determine these values, set the function equal to zero and solve for x:
0 = 3(x-2)(x+1)(x-4)
This equation is true when x equals 2, -1, or 4, since any of those values would make at least one of the factors equal to zero, which in turn makes the entire product zero. Therefore, the zeros of the function are x = 2, x = -1, and x = 4.

Answer:
630 square meters.
Step-by-step explanation:
Given:
A triangular prism has an equilateral triangle base whose sides are 6 meters. The height of the prism is 35 meters, and the height of the base is 5.2 meters.
Question asked:
What is the lateral surface area of the prism?
Solution:
As we know:
[tex]Lateral\ surface\ area\ of\ the\ prism=Perimeter\ of\ the\ base\times height\ of\ the\ prism[/tex]
Perimeter of the equilateral triangle base = 6 + 6 + 6 = 18 meters
The height of the prism = 35 meters
Lateral surface area of the prism = 18 [tex]\times[/tex] 35 = 630 square meters.
Thus, lateral surface area of the prism is 630 square meters.
32 is 20% of what number?
A) 64
B)89
C)128
D)160
Answer:
D) 160
Step-by-step explanation:
20% × n = 32
20 /100 × n = 32
Multiplying both sides by 100 and dividing both sides by 20,
n = 32 × 100 /20
n = 160
Answer:
D, 160
Step-by-step explanation:
Hello!
To find the answer to this question, we have can represent any number as "n."
Since 20% is the same as [tex]\frac{20}{100}[/tex], we have:
[tex]\frac{20}{100}[/tex] * n = 32
Now we multiply both sides by 100 to get rid of the fraction:
20n = 3200
And divide both sides by 20:
n = 160.
Thus, the answer is [tex]\boxed{160{\text{\:or\:D.}}}[/tex]

Actually, the lesson is giving you wrong information. The exponential function written in the example does not work for the point (4, 24).
Here's another way to look at it.
Given
two points: (x1, y1) and (x2, y2)
Solution
The exponential function can be written as ...
y = (y1)(y2/y1)^((x -x1)/(x2 -x1))
Example
For the example points, the function would be ...
y = (6)(24/6)^((x-2)/(4-2)) = 6·4^(x/2 -1) = (6/4)(4^(1/2))^x = (3/2)2^x
Check
For x=2, y=(3/2)2^2 = 6. For x=4, y = (3/2)2^4 = 24.
You will notice that we figure out "b" and "a" as a part of the process of simplifying the equation. The equation would work perfectly well without simplification.
_____
1. Given points (2, 50) and (3, 250), the equation is ...
f(x) = 50(250/50)^((x -2)/(3 -2)) = 50·5^(x -2) = (50/25)5^x
f(x) = 2·5^x . . . b = 5; a = 2
__
2. Given points (1, 3) and (2, 9/2), the equation is ...
f(x) = (3)(3/(9/2))^((x -1)/(2 -1)) = (3)(2/3)^(x -1) = (3/(2/3))(2/3)^x
f(x) = (9/2)(2/3)^x . . . b = 2/3; a = 9/2
__
3. Given points (3, 32) and (4, 128), the equation is ...
f(x) = (32)(128/32)^((x -3)/(4 -3)) = (32)4^(x -3) = (32/64)4^x
f(x) = (1/2)4^x . . . b = 4; a = 1/2
_____
Additional comments
The usual rules of exponents are useful in this:
a^(b+c) = (a^b)(a^c)
a^(bc) = (a^b)^c
a^-b = 1/a^b

What is the value of h?
H = 20
VALUE OF H IS 20
WHEN YOU ADD 20 AND 20 IT WILL GIVE 40
The value of h using concept of missing angles is: h = 55
How to find the missing angle?We know that the sum of angles on a straight line is 180 degrees.
Thus, the remaining two internal angles of the triangle are:
180 - 2h and 180 - 2h
We also know that the sum of angles in a triangle is 180 degrees. Thus:
180 - 2h + 180 - 2h + 40 = 180
400 - 4h = 180
4h = 400 - 180
4h = 220
h = 220/4
h = 55
