A thin rectangular sheet of metal is 6 inches wide and 10 inches long. The sheet of metal is to be rolled to form a cylinder so that one dimension becomes the circumference of the cylinder and the other dimension becomes the height. What is the volume of the largest possible cylinder formed

Answers

Answer 1

Answer:

Length of the Rectangle is to be considered as the circumference of the resulting cylinder and the width of the rectangle should be considered as the height of the cylinder only then we get the maximum volume of the cylinder which is 47.77[tex]in^3[/tex]

Step-by-step explanation:

The given dimensions are

Width of the rectangle is  6inches.

Length of the rectangle 10inches.

Now we need to choose in what orientation we need to use the length and the width of the rectangle so that it can be rolled into a rectangle and we get the maximum volume of the resulting cylinder.

so lets consider two cases

CASE-1: width of the rectangle is to be rolled as the circumference of the cylinder and length of the rectangle is to used as the height of the cylinder

 2*pi*r = 6

      r = [tex]\frac{6}{2pi}[/tex]

      r = [tex]\frac{3}{pi}[/tex] Inch

and the height = 10inch.

Volume of the resultant cylinder will be

   = [tex]pi*r^2*h[/tex]

   = [tex]pi*(\frac{3}{pi} )^2*10[/tex]

   = [tex]\frac{9}{pi}*10[/tex]

   = [tex]\frac{90}{pi}[/tex] = 28.662 [tex]in^3[/tex]

CASE-2: When the length of the rectangle is to used as the circumference of the resultant cylinder and the width of the cylinder is used as the height of the cylinder.

2*pi*r= 10

         r =  [tex]\frac{5}{pi}[/tex]

and the height of the cylinder is 6 inch

Now the volume of the cylinder will be

 Volume= [tex]pi*r^2*h[/tex]

              = [tex]pi*(\frac{5}{pi} )^2*6[/tex]

              = [tex]\frac{25}{pi}*6[/tex]

              = [tex]\frac{150}{pi}[/tex] = 47.77[tex]in^3[/tex]

Clearly we have the second case in which the resulting Cylinder will have the maximum volume.

Therefore the CASE-2 will provide the maximum Volume of 47.77[tex]in^3[/tex] to the resulting cylinder in which the length of the rectangle is to be considered as the circumference of the Cylinder and the width of the rectangle is to be considered as the height of the cylinder.

If x and y are positive integers is x - y always positive explain

Answers

Note that x and y are nonzero integers. It means that x and y will always have same sign (both are either positive or negative, since they are nonzero). Hence, xy term is always positive.

Answer:

No, if y happens to be a larger integer than x, then the result will be negative.  

Step-by-step explanation:

For example, lets say that x=4 and y=9, so x-y = 4-9 = -5.  

But if we were to reverse it and make x=9 and y=4, then x-y = 9-4 = 5.

A school lunch contains 12 cheese sticks. Seventy-five students buy the lunch. What is the total number of cheese sticks served?

Answers

Answer:

900 cheese sticks served (thats a lot of cheese)

Step-by-step explanation:

You can multiply to find how much in total

12*75

you’d get 900

Total number of cheese sticks served in 75 school lunches is 900.

Given that a school lunch contains 12 cheese sticks and 75 students buy the lunch,

we have to find the total number of cheese sticks served.

To find the solution,

We can use a simple multiplication formula that says,

The total number of cheese sticks served equals the number of cheese sticks in one lunch multiplied by the number of lunches served.

Therefore,

we can write,

⇒Total number of cheese sticks served = Number of cheese sticks in one lunch x Number of lunches served

As there are 75 students who buy the lunch,

We can find the number of lunches served by dividing the total number of students by the number of students in one lunch.

Since one lunch contains 12 cheese sticks, we can write,

⇒ Number of lunches served = Total number of students / Number of students in one lunch

⇒ Number of lunches served = 75 / 1

⇒ Number of lunches served = 75

Now that we know the number of lunches served,

we can use the multiplication formula to find the total number of cheese sticks served,

Total number of cheese sticks served = Number of cheese sticks in one lunch x Number of lunches served

⇒ Total number of cheese sticks served = 12 x 75

⇒ Total number of cheese sticks served = 900

Therefore,

The total number of cheese sticks served in 75 school lunches is 900.

what is the area of a shaded region in the quarter circle
radius 12​

Answers

Answer:

I guess that the shaded area is a quarter of a circle of radius 12 units.

Is easy to know that the area, will be equal to the quotient between the area of a circle of radius 12, and 4

We know that the area of a circle of radius R is:

A = pi*R^2

in this case, R = 12

pi = 3.14

Then:

A = 3.14*12^2 = 452.16

And a fourth of that is:

A/4 = (452.16)/4 = 113.04

The area of the shaded region is 113.04 square units

the mean of a,b,c,and d is 9 and the mean of a,b,c,d,e and f is 12. find the mean of e and f​

Answers

Answer:

mean of e + f = 18

Step-by-step explanation:

(a + b + c + d)/4 = 9         Multiply by 4

a + b + c + d = 9 * 4 = 36

(a + b + c + d + e + f ) / 6 = 12

but a + b + c + d = 36

(36 + e + f)/6 = 12             Multiply by 6

36 + e + f = 72                 Subtract 36 from both sides

e + f = 36                         Divide by 2 to find the mean.

(e + f)/2 = 36/2

The equation modeling the population growth of a small town is P(t)=30000(1.02)^t, where P represents the population, and t represents the years from now. What is the approximate population change that occurs between 2 years from now and 10 years from now.

Answers

Answer:

5358

Step-by-step explanation:

The equation modeling the population growth of a small town is given as:

P(t)=30000(1.02)^t

When t = 2

P(2) = 30000(1.02)^2

P(2) = 31212

When t = 10

P(10) = 30000(1.02)^10

P(10) = 36569.8326

The approximate population change that occurs between 2 years from now and 10 years from now is calculated as:

= P(10) - P(2)

= 36569.83259984272 − 31212

= 5357.8325998

Approximately ≈ 5358

Answer:

Step-by-step explanation:

Perimeter = 30cm

a + a + a = 30

3a = 30

hence a = 10cm

For the rectangle:

Perimeter = 30cm

a + a + b + b = 30

but a = 10cm

10 + 10 + b + b = 30

20 + 2b = 30

2b = 10

hence b = 5cm

Perimeter of square = b + b + b + b

= 5 + 5 + 5 + 5 = 20cm

It has the same y-intercept and a different slope.
It has a different slope and a different y-intercept

Answers

Answer:

The correct option is;

It has the same slope and a different y-intercept

Step-by-step explanation:

The data on the table can be presented as follows;

x      [tex]{}[/tex]       y

-2/3     [tex]{}[/tex]   -3/4

-1/6     [tex]{}[/tex]    -9/16

1/3    [tex]{}[/tex]     -3/8

5/6    [tex]{}[/tex]   -3/16

The rate of change of the function, m = (-3/16 - (-3/4))/(5/6 - (-2/3)) = 3/8

The equation of the line given by the data points in point and slope form is given as follows;

y - (-3/16) = 3/8×(x - 5/6)

y = 3·x/8 - 5/16 - 3/16 = 3·x/8 - 1/2

y = 3·x/8 - 1/2

The y intercept is given at when x = 0, therefore, at the y-intercept, y = 3 × 0/8 - 1/2 = -1/2

The y-intercept is (0, -1/2)

The x-intercept occurs at y = 0, therefore, at the x-intercept, we have;

0 = 3·x/8 - 1/2

∴ 3·x/8 = 1/2

x = 4/3

Therefore, the x-intercept is 4/3 and the coordinates of the x-intercept is (4/3, 0)

Given that the x-intercept is different, the y-intercept of the two lines with the same slope are also different

The correct option is therefore that it has the same slope and a different y-intercept;
