Answer:
The cone has a volume of approximately 982.5 cubic centimetres.
* That answer sounds off to me, but I'm not sure. You might want to run through the logic yourself and see if you get the same results.
Step-by-step explanation:
The volume of a cone is one third that of a cylinder with the same height and base radius. In other words:
[tex]v = \pi r^{2} \frac{h}{3}[/tex]
But before using that, we need to know the value of h, height. What we are instead given is the slant height, or the length from tip to edge.
We can use that slant height along with the base radius to get the cone height, as the three of them are the edges of a right triangle, with slant height being the hypotenuse.
To get the height then we can say
[tex]h = \sqrt{s^{2} - r^{2}}[/tex]
Where h is height, s is slant, and r is radius.
[tex]h = \sqrt{14.8^{2} - 14^{2} }[/tex]
[tex]h = \sqrt{219.04 - 196}[/tex]
[tex]h = \sqrt{23.04}[/tex]
[tex]h = 4.8[/tex]
A very squat cone indeed.
Now we can plug that and the radius into the actual cone equation:
[tex]v = \pi (14cm)^{2} \frac{4.8cm}{3}\\= \pi 196cm^2 * 1.6cm\\\approx 985.2 cm^3[/tex]
Prove that the value of the expression (n+8)(n-4) - (n+3)(n-2) + 27 is not divisible by 3 for any whole number n.
The value of the expression (n+8)(n-4) - (n+3)(n-2) + 27 is not divisible by 3 for any whole number n
How to prove that the value of the expression (n+8)(n-4) - (n+3)(n-2) + 27 is not divisible by 3 for any whole number n?The expression is given as
(n+8)(n-4) - (n+3)(n-2) + 27
Open the brackets
So, we have
n^2 + 8n - 4n - 32 - n^2 - 3n + 2n - 6 + 27
Collect the like terms
So, we have
n^2 - n^2 - 3n + 8n - 4n + 2n - 32 - 6 + 27
Evaluate the like terms
So, we have
3n - 11
The above expression cannot be expressed as a factor of 3
Hence, the value of the expression (n+8)(n-4) - (n+3)(n-2) + 27 is not divisible by 3 for any whole number n

A sled team consists of 11 dogs and the musher. Each dog weighs 70 pounds and the musher weighs 160 pounds. What is the average weight of the sled team members?
a
68.5 pounds
b
115 pounds
c
73.5 pounds
d
77.5 pounds
The average weight of the sled team members is 77.5
What is an average value?Average value can be calculated by finding the sum of a set of numbers then count the total number, then divide the sum with the number of the counted values.
To calculate the average weight of the sled team members, then we know that there are 11 dogs and the musher, which implies that there are total number of 12 animals.
Then we can find the total number of the dogs as (11*70) =770 dogs, then we can add to the musher which makes the total number of (770+160)=930
Then the average weight of the sled team members is [tex]\frac{930}{12} =77.5[/tex]

(note: ignore the percent symbol when entering your answer. for example, if the answer is 42.1\b.1b, point, 1, percent, enter 42.142.142, point, 1.)
The answer is 60%
According to the original information given, the estimated average number of shoppers in the original store at any time(x) is 45.
In the question, it states that, in the new store, the manager estimates that an average of 90 shoppers per hour(60 minutes) enter the store, which is equivalent to 1.5 shoppers per minute(s).
The manager also estimates that each shoppers stays in the store for an average of 12 minute (t). Thus, by Little's law there are, on average,
x = s x t

select translation, reflection, or rotation to identify the single transformation that transforms ∆rst to ∆r′s′t′.
The single transformation that transforms ∆RST to ∆R'S'T' is a reflection.
Part A:
For the first figure it is visible that the orientation of the pre-image (∆RST) is similar to that of the image (∆R'S'T').The image is received from the pre-image through moving the pre-image a few units down. Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a translation.
Part B:
For the second figure ,it is visible that the orientation of the pre-image (∆RST) is similar to that of the image (∆R'S'T').The image is received from the pre-image through moving the pre-image a few units down and a few units to the right. Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a translation.
Part C:
For the third figure it is visible that the orientation of the pre-image (∆RST) isn't similar to that of the image (∆R'S'T').The image is received from the pre-image through rotating the pre-image a few 180 degrees. Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a rotation.
Part D:
For the fourth figure it is visible that the orientation of the pre-image (∆RST) isn't similar to that of the photograph (∆R'S'T').The image is received from the pre-image through reflecting the pre-image.

For the given quadratic function we have that:
Domain: Set of all real values.Range: y ≤ 3.What is the domain and range of the quadratic function?For a function h(x), we define the domain as the set of the inputs (values of x) and the range is the set of the outputs (values of y).
Generally, for all quadratic functions, the domain is the set of all real numbers, so we already know the domain.
Now let's look at the range.
The given function is:
h(x) = -12*(x - 4)^2 + 3
Remember that if a quadratic function has a vertex (h, k), then the vertex form is:
f(x) = A*(x - h)^2 + k
So the vertex here is (4, 3)
And we also can see that the leading coefficient of the quadratic function is negative. This means that the function opens downwards, so the vertex is the maximum.
Then the range is the set of all real values smaller than or equal to 3, then the range is:
R: y ≤ 3.

what percent of 54 is 23? explained
Answer: 42.59
Step-by-step explanation:
Step 1: First, write the problem as an equation: P% = X/Y
Step 2: Here, X is 23, Y is 54, so the equation is P% = 23/54
Step 3: A percent is a ratio of a number expressed out of 100. So P% means P/100
Step 4: Substitute P/100 instead of P% in the above equation, then P% = 23/54 becomes P/100 = 23/54
Step 5: Solve for P
P/100 = 23/54
P = (23/54) * 100 = 42.59
Therefore, 23 is 42.59 percent of 54

a list of measurements in increasing order is 4, 5, 6, 8, 10, and x . if the median of these measurements is six sevenths times their arithmetic mean, what is the value of x ?
In a list of measurements in increasing order: 4, 5, 6, 8, 10, and x, the value of x is 16.
To get the value of x, we will use algebraic expressions to demonstrate the given relationships.
If the median of these measurements is six sevenths times their arithmetic mean, then:
median = 6/7 x mean
Median (Md), is a single value at the middle of the data values arranged in increasing or decreasing order. On the other hand, arithmetic mean (μ) is the sum of the data values divided by its total number.
For the list of measurements in increasing order is 4, 5, 6, 8, 10, and x,
The median is between 6 and 8.
Md = 6+8/2
Md = 7
Evaluating the first equation using Md = 7:
median = 6/7 x mean
7 = 6/7 x mean
mean = 49/6
By definition,
mean = (4 + 5 + 6 + 8 + 10 + x)/6
Equating both equations for the mean:
49/6 = (4 + 5 + 6 + 8 + 10 + x)/6
49 = 33 + x

For a certain performance the theater sold 5 times as many lower level tickets as upper balcony tickets. The theater sold $37,500 in tickets for that performance. The money made from mezzanine tickets alone was 4 times the money made from upper balcony tickets. How many lower level tickets were sold for that performance?
Based on the calculation done below, the number of lower level tickets sold is 750.
How do we calculate the number of units sold from a word problem?Let:
L = number of lower-level tickets sold = 5U
M = number of mezzanine tickets sold
U = number of upper balcony tickets sold
We therefore have:
35L + 25M + 15U = 37,500 ...................... (1)
25M = 4 * 15U = 60U
Substituting L = 5U and 25M = 60U into equation (1) and solve for U, we have:
35(5U) + 60U + 15U = 37,500
175U + 60U + 15U = 37,500
250U = 37,500
U = 37,500 / 250
U = 150
