Answer:

34191.7πin³/sec

Step-by-step explanation:

Volume of circular come = 1/3pi x r² x h

When we differentiate this formula we have

dv/dt = 1/3π[r²dh/dt + 2rhdr/dt]

We have the following information

r = 138

H = 143 inch

dr/dt = 1.4

dh/dt = -2.8

When we plug into the formula

1/3π[130² x -2.8 + 2x138x143x1.4]

= 34191.7πin³/sec

Step-by-step explanation:

Answer:

x = 1+√83 i/6 and 1-√83 i/6

Step-by-step explanation:

Given the quadratic expression;

3x^2-x+7 =0

Using the general foemula to find x

x = -b±√b²-4ac/2a

From the equation

a = 3, b = -1 and c = 7

Substitute

x = -(-1)±√(1)²-4(3)(7)/2(3)

x = 1±√1-84/6

x = 1±√-83/6

x = 1±√83 i/6

x = 1+√83 i/6 and 1-√83 i/6

Answer:

1/5

Step-by-step explanation:

Equation: [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

Points: (-3, -9) and (22, -4)

[tex]y_{2}[/tex] is the second y point that shows up on the question, basically go by order. So it's -4

[tex]y_{1}[/tex] is -9, because again, in order of which coordinates pop-up first in the question

[tex]x_{2}[/tex] is 22, [tex]x_{1}[/tex] is -3

Now input into the equation, to make it easier we'll split the fraction into 2 equations:

[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex] = [tex]y_{2} - y_{1}[/tex] and [tex]x_{2} - x_{1}[/tex], we'll put them back in a fraction later

[tex]y_{2} - y_{1}[/tex] = -4 - (-9) = -4 + 9 = 5

[tex]x_{2} - x_{1}[/tex] = 22 - (-3) = 22 + 3 = 25

now put it in the fraction, remember y on top x on the bottom:

5/25, simplify, 1/5

Answer: The answer is A, C and D

Step-by-step explanation:

The expression that is true for (v) and (w) on the graph can be seen in options A, B and D

The expression of data on the graph takes a standard form of arrangement in terms of (x, y).

From the given information:

If we reduce (w) and (v) by a factor of 2 : 1 on the graph, we have;

This shows that v and w are perpendicular to each other, and the product of v.w = 20

Similarly, W = -2(-2, -5) because by opening the brackets we have:

W = (4, 10)

Answer:

Unlikely

Step-by-step explanation:

In a pool 4-14 you have the numbers: 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14. So there is only three numbers under 7 in this scenario.

Answer:

me breolllllll please

Answer: A

Step-by-step explanation:

If you write down the points you’ll get:

(2,6) & (3,9) & (5,15)

Next apply the expression which in this case:

A) y =3x

Now insert the numbers

1) (2,6) => 6=3(2)

2) (3,9) => 9=3(3)

3) (5,15) => 15=3(5)

So, A is correct.

Edit: Forgot to mention about the numbers placement.

(x,y) so numbers on the left is x while those on the right is y

Answer:

The answer is D, lll only.

Step-by-step explanation:

Just took the test on e d g e!

The statement that most directly applies to capitalism is III only.

Option D is the correct answer.

It is a system of the economy where means of production and distribution are owned by the private, not the government.

We have,

The economic system of capitalism is characterized by private ownership of the means of production and distribution of goods and services, as well as the profit motive as the driving force behind economic activity.

Based on this definition, statement III most directly applies to capitalism, as it highlights the central role of market forces in determining prices and availability of goods.

On the other hand,

Statement I, which suggests heavy government regulation of the industry, is not a typical feature of capitalism, as it implies a more interventionist approach by the government in the economy.

Capitalism generally favors a more limited role for the government in economic affairs, although some government regulations may still be present.

Statement II, which suggests that individuals can start some, but not all, kinds of enterprises, is also not a defining characteristic of capitalism.

In a capitalist system, individuals are generally free to start any kind of enterprise that they wish, provided they can obtain the necessary resources and meet any legal or regulatory requirements.

Therefore,

The statement that most directly applies to capitalism is III only.

Answer: James earns $50 more in commission than Rhoda for each laptop sold.

Step-by-step explanation:hope it helps

James earned $50 more than Rhoda.

A collection of information obtained through measurements, study, observations, or analysis is referred to as data. Facts, numbers, names, figures, or even descriptions of things may be included. In the form of graphs, charts, or tables, data is arranged.

Basic facts and entities like names and numbers are referred to as data. Weights, costs, sales volume, employee names, product names, addresses, tax identification numbers, and registration marks are just a few types of data.

Given:

In one month, Rhoda earns $2000 in commission for selling 10 laptops.

For, one laptop = 2000/10

                         = 200

Now, as from the graph

In one month, James earns $2500 in commission for selling 10 laptops.

For, one laptop = 2500/10

                         = 250

So, James earned $50 more than Rhoda.

Answer: 11.3 minutes

Step-by-step explanation: Exponential Distribution is a distribution with function of the form:

[tex]f(x)=\lambda.e^{-\lambda.x}[/tex]

often related to an amount of time until an event occur.

The greek letter λ is decay parameter and have a relationship with the mean:

[tex]\lambda=\frac{1}{\mu}[/tex]

and x is the amount of time

Probability in exponential distribution is given by

[tex]P(x<X)=1-e^{-\lambda.x}[/tex]

Percentile is a value below which a percentage of the data falls.

For the waiting line in a Piggly Wiggly checkout, 80th percentile will be

[tex]P(x<h)=0.8[/tex]

[tex]P(x<h)=1-e^{-\frac{1}{7}h}[/tex]

[tex]0.8=1-e^{-\frac{1}{7}h}[/tex]

[tex]e^{-\frac{h}{7} }=0.2[/tex]

[tex]-\frac{h}{7} =ln(0.2)[/tex]

h = 11.3

The 80th percentile of waiting times is 11.3 minutes.

Answer:

The 2nd one 1.96x + .69 < = 3

Step-by-step explanation:

I'm in algebra so I get this.

Basically it's $1.96 per pound of potatoes and "x" represents the amount of potatoes. So essentially you're multiplying 1.96 times how many pounds of potatoes there are. Than it says they only bought 1 pack of cookies and 1 pack is $0.69 so add that to your equation. And we know we only have $3 so that's our max, the most we can spend. So whatever $1.96 and $0.69 add up too has to be less than or equal too $3. And that's it!

Answer:

68.42%

Step-by-step explanation:

We need to find the percent of Cr in [tex]Cr_2O_3[/tex].

Mass of Cr = 52 amu

Mass of O = 16 amu

Firstly, we will find the molar mass of [tex]Cr_2O_3[/tex] as follows :

M = 2(52) + 3(16)

M = 152 amu

Percent of Cr in  [tex]Cr_2O_3[/tex] will be :

[tex]Cr=\dfrac{2\times 52}{152}\times 100\\\\=68.42\%[/tex]

Hence, the required percentage is 68.42%.
