What is the surface area of the entire sculpture? Use 3.14 for π.


*Surface area of the entire sculpture = Surface area of the cube - Surface area of the two circles + Curved surface area of the cylinder


*Surface area of the cube = 6s² (6 x side x side)
*Surface area of the two circles = 2πr² (2 x 3.14 x radius x radius)
*Curved surface area of the cylinder =2πrh (2 x 3.14 x radius x height)

Answer:

The area of the pizza with a diameter of 18 inches is 254.34 inches.

Step-by-step explanation:

The formula to find the area of a cirlce is A = pi x r^2 or pi times radius squared.

Second, we need to find our radius. To find the radius we need to divide the diameter by 2 to get the radius. In this case; 18 divided by 2 is 9.

Then, we need to plug the radius in the formula:

A = 3.14 x 9^2

9 squared or 9 times 9 equals 81

Next, multiply 81 by 3.14 and you get 254.34

Lastly, add the units of measurement, which would be inches.

Answer:

I'm gonna go with rectangle and square

Step-by-step explanation:

rectangle: 2 pairs of parallel sides. 4 right angles (90°). Opposite sides are parallel and congruent. All angles are congruent.

Square: 4 congruent sides. 4 right angles (90°). Opposite sides are parallel. All angles are congruent.

The rectangle and square are the types of quadrilaterals that have four congruent angles. Then the correct option is A.

It is a polygon with four sides. The total interior angle is 360 degrees.

Types of the quadrilateral are as follows;

Thus, the rectangle and square are the types of quadrilaterals that have four congruent angles.

Then the correct option is A.

Step-by-step explanation:

I got this question too and I got it right. ❤️

Mr. Sanders most certainly discovered that one-third of pupils have done 12 or more paintings because the histogram has six bars, two of which reflect students who have completed 12 or more paintings. The actual percentage of pupils who have completed 12 or more paintings is [tex]\frac{4}{19}[/tex].

Therefore, the answer is "[tex]\to (1^{st}\ box) = 6 (2^{nd}\ box) = 2 (3^{rd}\ box) = \frac{2}{3}[/tex]"

Hey there! I'm happy to help you!

The formula for the volume of a sphere is [tex]V=\frac{4}{3} \pi r^{3}[/tex], which is the the radius cubed multiplied by pi and 4/3. There are a lot of interesting proof videos out there about how this formula is derived and it is super cool and you would love it!

If our radius is 8 centimeters, we can plug it in like this:

[tex]V=\frac{4}{3} \pi (8)^{3}[/tex]

Answer:

-The subset consists of all of the outcomes where you do not lose.

-The subset consists of all of the outcomes where your friend loses, or there is a tie.

Step-by-step explanation:

Khan Academy

Statements that describe the subset A are option (a) and option (d).

A set of which all the elements are contained in another set. Subset can be empty or equal to the set.

Given sample of space S = {1,2,3,4,5,6,7,8,9}

And subset M of S = {1,4,7} where you win in the spinner game.

If the spinner lands on the subset N of S = {3,6,9} , you tie.

Given A = {1,3,4,6,7,9,} is a subset of S.

Now to verify the options;

In option (a) ;

The subset consists of all the outcomes where you win that means your friend loses or there is a tie. Because subset A does not contain any elements of subset {2,5,8},  where you lose.

In option (b) ;

The subset consists of all the outcomes where your friend ties. That means subset should only contain the elements of subset N = {3,6,9}. Which is clearly not. So this option is incorrect.

In option (c) ;

The subset consists of all the outcomes where there is not a tie and your friend does not win. That means subset S should only contain the elements from {1,4,7}. which is contradiction so this option is also incorrect.

In option (d) ;

The subset consists of all the outcomes where you do not lose. That means subset does not have any element from {2,5,8}.

Hence Correct answers are option (a) and option (d).

The complete question is ;

You and your friend are playing a game where you spin a circular spinner with nine numbered sections of equal size. In this game, you win if the spinner lands on 1,4, or 7. Your friend wins if the spinner lands on 2,5, or 8. You tie if the spinner lands on 3,6, or 9.

All the possible outcomes of the game are listed in the sample space S= { 1,2,3,4,5,6,7,8,9} If we take A= { 1,3,4,6,7,9} as a subset of the sample space, which of the statements below describe the subset A?

a) The subset consists of all the outcomes where your friend loses or there is a tie.

b) The subset consists of all the outcomes where your friend ties.

c) The subset consists of all the outcomes where there is not a tie and your friend does not win.

d) The subset consists of all the outcomes where you do not lose.

Answer:

  30 square units

Step-by-step explanation:

The area of the given right triangle can be found a couple of ways:

The missing side length can be found using the Pythagorean theorem relation between the sides:

  c² = a² +b²

  13² = a² +5²

  a² = 169 -25 = 144

  a = √144 = 12

Then the area is ...

  A = 1/2ab = 1/2(12)(5) = 30 . . . square units

__

The angle at lower right can be found from the trig relation ...

  Cos = Adjacent/Hypotenuse

  cos(A) = 5/13

  A = arccos(5/13) ≈ 67.38°

The area can be found from these side lengths and the angle:

  A = 1/2bc·sin(A)

  A = 1/2(5)(13)sin(67.38°) = 30 . . . square units

_____

Additional comment

The sine of the angle can be computed from the cosine using the identity ...

  sin(x) = √(1 -cos²(x))

In this case, the sine of the angle would be found to be 12/13, so the area would be computed as ...

  A = 1/2(5)(13)(12/13) = 1/2(12)(5) . . . . same as using the Pythagorean theorem

Answer:

He did not distribute the negative sign when he subtracted.

Step-by-step explanation:

x-(x+1) is equal to a -1. He did not distribute the negative.

In third step, he did not distribute the negative sign when he subtracted. Then the correct option is C.

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

Mr. Knotts found the difference of the following expression.

The expression is given below.

[tex]\rm \rightarrow \dfrac{x}{x^2-1} - \dfrac{1}{x -1}[/tex]

Then the first step of the expression will be

[tex]\rm \rightarrow \dfrac{x}{(x+1)(x-1)} - \dfrac{1}{x -1}[/tex]

The second step of the expression will be

[tex]\rm \rightarrow \dfrac{x}{(x+1)(x-1)} - \dfrac{1(x+1)}{(x+1)(x -1)}[/tex]

The third step of the expression will be

[tex]\rm \rightarrow \dfrac{x - (x +1)}{(x+1)(x-1)}\\\\\rm \rightarrow \dfrac{x - x -1}{(x+1)(x-1)}[/tex]

In third step, he did not distribute the negative sign when he subtracted.

Then the correct option is C.

Answer:

x = 4, f(x) = 0

Step-by-step explanation:

Given

f(x) = [tex]\frac{1}{x-4}[/tex]

The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non zero for this value then it is a vertical asymptote.

x - 4 = 0 ⇒ x = 4 ← is the vertical asymptote of f(x)

Since the degree of the denominator > degree of denominator

There is a horizontal asymptote at y = 0 , that is f(x) = 0

Answer:

The solution of the given inequality  n < 5

Step-by-step explanation:

Explanation:-

Given inequality

                     [tex]\frac{1}{4} (8 n -12 ) < n +2[/tex]

Step(i):-

 Cross multiplication '4' we get

                    8 n - 12 < 4 ( n +2)

                    8 n - 12 < 4 n + 4×2

                    8 n - 12 < 4 n +8

      Subtracting  '4 n ' on both sides, we get

                 8 n - 4 n - 12 < 4 n - 4 n +8

                 4 n - 12  <  8

Step(ii):-

Adding ' 12 ' on both sides , we get

                4 n -12 + 12 < 8 + 12

                               4 n < 20

Dividing "4' on both sides , we get

                                 n < 5

The solution is n < 5

Conclusion:-

The solution of the given inequality  n < 5

Step-by-step explanation:

First, you fill in 1 for n:

= 2 x 4(1)

= 2 x 4

= 8

Next, I filled in 4 for n:

= 2 x 4(4)

= 2 x 16

= 32

Then, I filled in 8 for n:

= 2 x 4(8)

= 2 x 32
