For this case we have that by definition, the volume of a cylinder is given by:

[tex]V = \pi * r ^ 2 * h[/tex]

Where:

V: It's the volume

A: It is the radius of the cylinder

h: It is the height of the cylinder

We have to:

[tex]V = \pi * (7.2) ^ 2 * 12\\V = \pi * 51.84 * 12\\V = 1954.32195794513 \ m ^ 3[/tex]

On the other hand, the volume of the cone is given by:

[tex]V = \frac {\pi * r ^ 2 * h} {3}[/tex]

V: It's the volume

A: It is the cone radius

h: It is the height of the cone

We have:

[tex]V = \frac {\pi * (7.2) ^ 2 * 11} {3}\\V = \frac {\pi * 51.84 * 11} {3}\\V = 597.153931594347 \ m ^ 3[/tex]

Thus, the total volume is given by:

[tex]V = 2551.47588954 \ m ^ 3[/tex]

From conservation of angular velocity the larger pulley will rotate at a speed of 500 rpm.

The conservation of angular velocity states that the angular velocity for a conjugate system will be always equal to the angular velocity of a part of the same system.

Mathematically -

r1ω1 = r2ω2 = r3ω3 = ................. = rnωn

where r is the radius of the circular belts, ω is the angular velocity and n is the total number of segments in the conjugate system.

Given that a pair of belted pulleys have diameters of 18 in. and 12 in. Also given that the smaller pulley turns at 750 rpm.

The radius of the pulleys are 9 in. and 6 in. respectively.

Let x rpm be the speed of the larger pulley turn.

From conservation of angular velocity, we have

⇒ 6 * 750 = 9 * x

⇒ x = (6 * 750)/9

∴  x = 500 rpm

Therefore, from conservation of angular velocity the larger pulley will rotate at a speed of 500 rpm.

Answer:

B

Step-by-step explanation:

B is the correct answer.  Since Mrs. Hooper and Mr. Anderson had to call a total of 8 parents, you know the first equation must be either A or B (H + A = 8).

Since you know that Mrs. Hooper had to call 2 more parents than Mr. Anderson, the equation will have to have H + 2 on one side; that's how you know the correct answer is B.

The set of equations which correctly describes the phone calls made is A. H + A = 8 ; H = A + 2.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

H denote the number of calls Mrs. Hooper made and A denote the number of calls Mr. Anderson made.

Mrs. Hooper and Mr. Anderson had to call a total of eight parents.

So, the equation representing this is, H + A = 8

Mrs. Hooper needed to call two more students than Mr. Anderson.

H = A + 2

So the set of equations are,

H + A = 8 ; H = A + 2

Hence the correct option is A. H + A = 8 ; H = A + 2

The probability is 1:2

Answer:

4/18

Step-by-step explanation:

You have 5 WHITE marbles and 5 Black marbles.

The probability of drawing a WHITE marble is 5/10  or 1/2

And the probability of drawing the second (marble another WHITE marble) is 4/9

So 1/2 x 4/9 = 4/18 or 5/10 x 4/9 = 20/90 / 5 = 4/18

Therefore the probability of drawing a WHITE marble not replacing it then drawing another WHITE marble is 4/18

Answer:

Graph of given function doesn't exist.

Step-by-step explanation:

Given equation is [tex]|x|=-2[/tex].

Now we need to determine about how do you graph [tex]|x|=-2[/tex].

We know that [tex]|x|[/tex] represents absolute value function.

By definition of absolute value function, we know  that output of [tex]|x|[/tex] must always be positive.

But in given equation [tex]|x|=-2[/tex], we have output -2 which is negative.

That is not possible.

Hence there is no solution to the given problem [tex]|x|=-2[/tex].

So the graph of given function doesn't exist.

Answer:

C. 0.26

Step-by-step explanation:

If the student selected was a sophomore at the jazz concert, we'd use the table to find the student being out of 35 students in the same situation. To get the correct answer you must take 35 divided by the total number of students attended (137). Therefore, 35/137= 0.255 rounded to the nearest tenth would be 0.26

Hope this helps! :)

Answer:

C) 0.26

Step-by-step explanation:

35 sophomores attended the jazz concert out of 137 total students.

Divide 35 by 137, which is roughly 0.25547445...

Round two decimal places and you will get 0.26.

The two tangent lines for each circle are the same length. Set the equations to equal and solve for x.

1. 4x + 3 = 3x +12

Subtract 3x from each side:

x +3 = 12

Subtract 3 from both sides:

x = 9

2. -2 + x = 2x -7

Subtract 2x from both sides:

-2 - x =  -7

Add 2 to each side:

-x = -5

Multiply both sides by -1:

x = 5

The value of x for both the circles is 9  and 5 .

A tangent for a circle is defined as a straight line which touches the circle at just one point.

The tangent is perpendicular to the radius of the circle at the point of where tangent touches the circle.

It is given in the question to find the value of x

When two tangents meet at a point C , the distance between the point of tangency and the point C is equal for both the tangent.

Therefore for the given circle

For first circle to solve for x , we will equate the two distances

4x + 3 = 3x +12

x +3 = 12

x = 9

-2 + x = 2x -7

-2 - x =  -7

-x = -5

x = 5

Therefore the value of x for both the circles is 9  and 5 .

Answer:

Option D 4 inches is correct.

Step-by-step explanation:

Area of trapezoid = 48 square inches

Base a = 9

Base b = 15

We need to find the height h.

The formula for area of trapezoid is

Area = (a+b)/2 * h

Putting the values, we get

48 = ( 9+15)/2 * h

48 = (24)/2 * h

48 = 12 *h

=> h = 48/12

h = 4 inches

So, Option D 4 inches is correct.

Answer:

4 in.

Step-by-step explanation:

The area of a trapezium is calculated using the formula:

[tex]Area=\frac{1}{2}(Sum\:of\:the\:bases)\times height[/tex]

The given tra-pezoid has area [tex]48[/tex] square inches.

The bases are given as 9 inches and 15 inches.

We plug in the known values into the formula to get;

[tex]48=\frac{1}{2}(9+15)\times height[/tex]

[tex]48=\frac{1}{2}(24)\times height[/tex]

[tex]48=12\times height[/tex]

Divide both sides by 12.

[tex]\frac{48}{12}=height[/tex]

[tex]4 in.=height[/tex]

Therefore the height of the trapezoid is 2 inches.

The probability that the sum of the two resulting numbers is greater than 5 is 2/3

The probability that the product of the two resulting numbers is odd is 1/3

How to determine the required probabilities

From the question, we have the following parameters that can be used in our computation:

Die = {1, 2, 2, 4}

Spinner = {3, 4, 7}

The sample space is represented as

Space = {(1, 3), (1, 4), (1, 7), (2, 3), (2, 4), (2, 7), (2, 3), (2, 4), (2, 7), (4, 3), (4, 4), (4, 7)}

For the sum greater than 5, we have the following space

Space = {4, 5, 8, 5, 6, 9, 5, 6, 9, 7, 8, 11}

In the above, we have

Total = 12

Sum greater than 5 = 8

So, this probability is

P = 8/12 = 2/3

For the product resulting in odd numbers, we have the following space

Space = {3, 4, 7, 6, 8, 14, 6, 8, 14, 9, 12, 21}

In the above, we have

Total = 12

Odd results = 4

So, this probability is

P = 4/12 = 1/3

Hence, the probabilities are 2/3 and 1/3

Symbol answer: 6/12 < 9/12

Step-by-Step explanation:

Common knowledge: Anytime you have the same numerator, with a different denominator, the one with the bigger denominator is always smaller. For example, if had a pizza with 6 slices and a pizza with 4 slices, the one with 6 slices and smaller and the one with 4 slices and bigger. Even though 6>4 that mindset has to change when thinking about a problem like this.

Another explanation:

If you still don’t get it, simply find a common denominator, so we’ll choose 12. Take 3/6 and multiply that by 2/2 so you get 6/12 and then take 3/4 and multiply that by 3/3 on both the (numerator and denominator) and that equals 9/12.

So now you have the expression: 6/12<9/12.

I think cause you nees to add all of the socks together and put how many socks was black

Hello there!

Answer:

8/13

Step-by-step explanation:

In order to find the probability in questions like this, we would need to find the number that we want to get and the total amount of possibilities.

Important information in the text:

With the information, we can find the probability.

In the question, we are trying to find the probability of picking out a black sock, and there is 8 black socks. The 8 will go on our numerator.

Our denominator would be the total amount of things that leads to our probability. Since we only have 8 black socks and 5 yellow socks, we would add 8 + 5 to get the total amount of socks.

8 + 5 = 13

The 13 will go in the denominator.

When you put all of the stuff together, you should get 8/13. You can't simplify it because 13 is an odd number that can't get any smaller.

8/13 is the probability of picking out a black sock
