6/9 is a rational number. Select all the rational numbers that are equivalent to 6/9

Answer:

4/9

Step-by-step explanation:

I think because you take the total and the amount of red you have

The probability of picking a red marble randomly from the bag will be equal to 0.44 .

It is given that there are total 9 marbles in a bag out of which 4 are red marbles.

We have to find the probability of picking a red marble randomly from the bag.

What do you mean by probability ?

Probability is the possibility or chance of an event to occur and is given by ratio of no. of favorable outcomes to total no. of outcomes.

As per the question ;

The total no. of outcomes (marbles) = 9

The no. of favorable outcomes (red marbles) = 4

We know that , probability is given by ;

Probability = No. of favorable outcomes / Total no. of outcomes

So  ;

The probability of picking a red marble randomly from the bag will be equal to  ;

Probability = 4 / 9

P(E) = 0.44

Thus , the probability of picking a red marble randomly from the bag will be equal to 0.44 .

Answer:

5k² - 7k + 6

Step-by-step explanation:

The perimeter of the figure given = the sum of all sides of the figure.

Perimeter = (k² - 9k + 23) + (k² + k) + (k² + k) + (2k² - 17)

Simply the expression as follows:

Perimeter = k² - 9k + 23 + k² + k + k² + k + 2k² - 17

Combine like terms

Perimeter = k² + k² + k² + 2k² - 9k + k + k + 23 - 17 (like terms are terms with the same degree)

Perimeter = 5k² - 7k + 6

Answer:welll i think its 5

Step-by-step explanation:

Answer:

w= 3 feet

h= 5 feet

Step-by-step explanation:

H=height; W=width=2H-7ft

W=2H-7ft

2H+4W=22ft Substitute for W

2H+4(2H-7ft)=22ft

2H+8H-28ft=22ft Add 28 ft to each side.

10H=50ft

H=5 ft ANSWER 1: The bookshelf is 5 feet high.

W=2H-7ft=2(5ft)-7ft=10ft-7ft=3ft

ANSWER 2: the bookshelf is 3 feet wide.

CHECK:

2H+4W=22ft

2(5ft)+4(3ft)=22ft

10ft+12ft=22ft

Answer:

For revolution about the y-axis:

For revolution about the x-axis, swap x and y.

Step-by-step explanation:

The methods for computing the volume of revolution of  a plane figure are ...

The name of the method describes the shape of the differential of volume.

__

Cylindrical shell

For revolution about the y-axis, the differential of volume is a cylindrical shell of radius x, thickness dx, and height y2 -y1, where y2 = f2(x) and y1 = f1(x). (y2 > y1) Integration is over x.

  dV = 2π·x·(f2(x) -f1(x))·dx

For revolution about the x-axis, the variables x and y are interchanged.

__

Disk

For revolution about the y-axis, the differential of volume is a donut or disk of inner radius f1(y) = x1 and outer radius f2(y) = x2 (x1 ≤ x2). The thickness is dy. Integration is over y.

  dV = π·(f2(y)^2 -f1(y)^2)·dy

For revolution about the x-axis, the variables x and y are interchanged.

__

The preferred method is the one that gives simple integrable functions over a single range of integration. For some geometries, the integration range must be split, because the shape of the differential volume cannot be described by a simple rectangle whose length is the difference of functions of the integration variable.

When the differential of volume can be drawn either way, the choice of methods may be arbitrary. I usually choose the method that gives the simplest integrand.

_____

Additional comment

When the axis of revolution is something other than a coordinate axis, the radius of revolution becomes a different function than a simple x (or y). For example, if the axis of revolution is x=a, the radius of the cylindrical shell will be a-x (for x ≤ a) or x-a (for a ≤ x).

Here's an example of the use of the disk method.

Step-by-step explanation:

A1= area of the rectangle

A1= 4yd • 10yd

A1= 40 square yd

A2= area of the part of the circular section

A2= 180°• pi • 4 square yd/360°

A2= 180° • 16yd • pi/ 360°

A2= 16yd•pi/2

A2= 8yd•pi

Answer: (C). There are 200 animals, and the cost is $8,000 daily.

Step-by-step explanation: We already know (x) is the number of animals measured in hundreds and it would go on the x axis. And that would mean that (f) is going to be on the y axis. Go over on the x axis 2 then for the y axis go up 8 on the y axis and you would get (2,8)= (200 animals, $8,000 a day)

There are 200 animals, and the cost is $8,000 daily

Answer:

The strip of 16 by 14 inches.

Let x be the corner of the square cut

Then the box would have height as x, length 16-2x and width 14-2x

Hence volume =  

Use derivative to test to find x for maximum volume

V'(x) =  

v"(x) =  

Equate first derivative to 0

Solutions are

x= 2.483 and x = 7.517

Practically cutting more than 7 inches is not possible from 14 inches dimention

Hence 2.483 is the side of square and maximum volume

Answer:

1,159 pieces of mail

Step-by-step explanation:

From the information given, you can write an inequality that indicates that the price of sending each piece of mail without the permit is higher than the price of purchasing the bulk-mail permit and then, you can solve for x that is the number of pieces of mail:

0.44x>0.276x+190

0.44x-0.276x>190

0.164x>190

x>190/0.164

x>1,158.5

According to this, the organization needs to send 1,159 pieces of mail in a year to make it cheaper to use a bulk-mail permit.

Step-by-step explanation: (-1/9, -1/2),(14/9, 4/3)

What you want to do is -1/9 + 14/9. Here our answer is 13/9. We then do 13/9 divided by 2 which in equation form is 13/9X1/2 which is 13/18. We want to solve the Y now. In equation form we do: 4/3 - 1/2 which equals 1/6 Therefore, the answer is (13/18, 1/6)

Answer:

f'(1)=150ln(1.5)

Step-by-step explanation:

I'm not sure why you would need a table since the limit definition of a derivative (from what I'm remembering) gives you the exact formula anyway... so hopefully this at least helps point you in the right direction.

My work is in the attachment but I do want to address the elephant on the blackboard real quick.

You'll see that I got to the point where I isolated the h's and just stated the limit equaled the natural log of something out of nowhere. This is because, as far as I know, the way to show that is true is through the use of limits going to infinity. And I'm assuming that you haven't even begun to talk about infinite limits yet, so I'm gonna ask you to just trust that that is true. (Also the proof is a little long and could be a question on it's own tbh. There are actually other methods to take this derivative but they involve knowing other derivatives and that kinda spoils a question of this caliber.)

Answer: 4 + (-n) and -n+4

==========================================================

Explanation:

Adding a negative is the same as subtracting. For example, 10-7 = 10+(-7)

So that's why 4-n is the same as 4 + (-n)

---------

Then we go from 4 + (-n) to -n+4 because we can add two items in any order.

The ratio of number of girls and boys in a class of 30 students is 7:8

The ratio of number of girls and boys if 5 new boys admit in the class.

Let the number of students be x.

According to the question,

7x + 8x = 30

or, 15x = 30

or, x = [tex] \large {\tt {\frac{30}{15}}} [/tex]

or, x = 2

7x = 7(2) = 14

8x = 8(2) = 16

There were 14 boys and 16 girls in the school.

After admitting 5 new boys, we get

14 + 5 = 19

The ratio of number of girls and boys now is 16:19.

Answer:

The width of the frame is 3 inches

Step-by-step explanation:

We are told that the inner rectangle is 10 inches by 16 inches.

It means the outer rectangle has to be (L = 10 + 2x) by (W = 16 + 2x),

Where x represents the width of the frame.

The perimeter of the frame is given by; p = 2L + 2W

p = 2(10+2x) + 2(16+2x)

We are given perimeter, P = 76

Thus;

2(10 + 2x) + 2(16 + 2x) = 76

Divide both sides by 2 to give;

(10+2x) + (16+2x) = 38

(10+16) + (2x+2x) = 38

4x = 38 - 26

4x = 12

x = 12/4 = 3

The width of the frame is x = 3 inches
