The volume of a cone is 80π cubic units. The radius of this cone is tripled.

Eric says the new volume will be tripled. It is 240π cubic units.
Natalie says the new volume will be multiplied by 9. It is 720π cubic units.
Who is correct? Explain your reasoning.

Answers

Natalie is correct. The volume of a cone is given by the formula:

V = (1/3)πr^2h

Where V is the volume, r is the radius, and h is the height. If the radius of a cone is tripled, the volume of the cone will be multiplied by 9. This is because the radius is squared in the formula, so tripling the radius is the same as multiplying it by 3*3=9.

To see this more clearly, consider the following example:

Suppose the radius of a cone is 2 units and the height is 4 units. The volume of the cone is:

V = (1/3)π(2^2)(4) = (1/3)π(4)(4) = (1/3)π(16) = 16π/3 cubic units

If we triple the radius of the cone to 6 units, the volume of the cone becomes:

V = (1/3)π(6^2)(4) = (1/3)π(36)(4) = (1/3)π(144) = 144π/3 cubic units

The volume of the cone has been multiplied by 9.

Answer:

2 5/18

Step-by-step explanation:

7 2/3 - 3 1/6 - 2 2/9 =                    Given    7 12/18 - 3 3/18 - 2 4/18 =              Bring to common denominator of 18(7 - 3 - 2) + (12 - 3 - 4)/18  =           Group integers and fractions2 + 5/18 =                                       Simplify2 5/18                                            Answer
The correct answer is 2 5/18

The first step is to find a common denominator. (I will be using • to represent multiplication) The lowest common denominator that 3, 6, and 9 share is 18.
3 • 6 = 18
6 • 3 = 18
9 • 2 = 18

To rewrite your numbers using 18 as a denominator, you must multiply the numerator and denominator by the same number.
Since 3 • 6 = 18, 7 2/3 will be rewritten as
7 12/18 (since 2 • 6 = 12) we don’t have to worry about the whole number (7), so leave it as it is.

3 1/6 can be rewritten as
3 3/18, since 6 • 3 = 18 and 3 • 6 = 18
Once again we leave the whole number alone

2 2/9 can be rewritten as
2 4/18, since 9 • 2 = 18 and 2 • 2 = 4

Now we simply subtract our whole numbers and our fractions. Let’s first subtract our whole numbers.

7 - 3 - 2 = 2

Now we can subtract our fractions. Remember that when we subtract fractions, the denominator stays the same. In other words, we only subtract the numerator and ignore the denominator.

12/18 - 3/18 - 4/18 = 5/18

Therefore youre solution is

2 5/18

Answer:

x = 19

z = 105

Step-by-step explanation:

z + 75 = 180

z = 105

6x - 39 = 75

6x = 114

x = 19

Answer:

x = 19

z = 105

Step-by-step explanation:

Because these are two intersecting lines, the two opposite angles are equal:

6x - 39 = 75

Solving this equation gives you x:

6x = 114

x = 19

In order to solve for z, we must remember that two angles on a straight line are supplementary angles meaning that, if added together, they equal 180°. In this case:

75 + z = 180

Solving this equation gives you z:

z = 105

Explain how a number can be described in relation to zero.

Answers

Zero is definitely regarded as being a number.The question of whether or not zero is a number is not a question about what zero is and what it means; it is a matter of how we choose to define the term “number”, whether we choose to apply the label “number" to the conceptual entity we call zero.So the definition of the word “number” is such zero is a number. This makes perfect sense, of course; it would be bizarre if what we call negative numbers were regarded as being numbers, but zero was not.In conclusion, then; zero is a number, by definition.

Answers

Answer:

3/4

Step-by-step explanation:

Since (p, r) lies on the line y = x + b,

we have,

r = p + b -----eq(1)

Since (2p, 5r) lies on the line y = 2x + b,

we have,

5r = 2(2p) + b -----eq(2)

Sub the value of r from eq(1) in eq(2),

5(p + b) = 4p + b

⇒ 5p + 5b = 4p + b

⇒ 5b - b = 4p - 5p

⇒ 4b = -p

⇒ b = -p/4

sub in eq(1)

r = p + (-p/4)

= p - p/4

= 3p/4

⇒ r = 3p/4

⇒ r/p = 3/4

Answer:

3/4

Step-by-step explanation:

We have two lines:

r = p + b     eq(1)

5r = 4p + b   eq(2)

eq(2) - eq(1)

4r = 3p

dividing by 4p

r/p = 3/4

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?

Answers

C(7, 4) = 7! / (4!(7-4)!) = (7 * 6 * 5) / (3 * 2 * 1) = 35

and

C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287

Multiply these two combinations since the faculty members and students are selected independently:

Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045

Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
To determine the number of ways to form the committee with 4 faculty members and 5 students, we need to calculate the combinations of faculty members and students separately and then multiply them together.

For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:

C(7, 4) = 7! / (4!(7 - 4)!) = 35.

So, there are 35 ways to select 4 faculty members from the 7 eligible ones.

For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:

C(13, 5) = 13! / (5!(13 - 5)!) = 1287.

Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.

To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:

35 * 1287 = 44,895.

Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

Hi! I will help with the second pic!

Explanation:

So the first step is too know the formula: y=mx+b (m being the slope and b being the y-intercept)

Now b is what you start with. So for example is your graphing y=3x+4 you would have to go up 4. Then you have too turn the slope into a fraction. So it would be 3/1. Start by going up 4 the go up 3 right one. (This isn’t the answer just an example)

Now for the answer. As we can see the orange line graph starts by going up 2. So that is our y-intercept (our b in the formula)

Now we have too find the point closest too that. Which is (5,1) Okay. Now how much did it go up from 2? It went 3 points up.

So that is our numerator. Now how much did it go to the right? 1 point to the right! So now we have our answer for the orange line one.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4−y5=2−2y8

4+−15y=2+−14y

−15y+4=−14y+2

Step 2: Add 1/4y to both sides.

−15y+4+14y=−14y+2+14y

120y+4=2

Step 3: Subtract 4 from both sides.

120y+4−4=2−4

120y=−2

Step 4: Multiply both sides by 20.

20*(120y)=(20)*(−2)

Answer:

y=−40

Answer:

y= -40

Step-by-step explanation:

4 - y/5 = 2 - 2y/8

4 - y/5 = 2 - y/4

4 x 20 - y x 20/5 = 2 x 20 - y x 20/4 (reduce the fractions)

4 x 20 - 4y = 2 x 20 - 5y

80 - 4y = 2 x 20 - 5y

80 - 4y = 40 - 5y

-4y + 5y = 40 - 80

y = 40 - 80

y = - 40
