How Much Cardboard Is Needed To Make The Single Slice Pizza Box Shown

Answers

Answer 1
Explanation

We must find the amount of cardboard needed to make a slice of pizza box which basically means finding the surface area of the piece of box shown. This is composed of five faces divided in three groups:

- Two equal triangular faces with a base of 6.7 in and a height of 11 in.

- Two equal rectangular faces with a base of 11.5 in and a height of 1 in.

- A single rectangular face with a base of 6.7 in and a height of 1 in.

The area of the piece of box is given by the sum of the areas of the 5 faces so let's find the area of the faces of each group.

The area of a triangle is given by half the product of the length of its base and its height. Then the area of each triangular face is:

[tex]A_t=\frac{6.7\times11}{2}=36.85[/tex]

So each triangular face has an area of 36.85 in².

The area of a rectangle is given by the product of its base and height. Then for the pair of equal rectangular faces we have:

[tex]A_{r1}=11.5\times1=11.5[/tex]

So each of these two faces has an area of 11.5 in².

The area of the remaining rectangular face is then given by:

[tex]A_{r2}=6.7\times1=6.7[/tex]

So the area of the last face is 6.7 in².

Then the total surface area is given by the sum of the areas of the 5 faces. Then we get:

[tex]A=2A_t+2A_{r1}+A_{r2}=2\times36.85+2\times11.5+6.7=103.4[/tex]Answer

Then the answer is 103.4

Prism B has a total surface area of 110 cm?O C. Prism A has a lateral surface area of 60 cm?D D. Prism B has a larger surface area.

Answers

Note that the lateral surface area is the area of the faces of the solid, excluding the cross-sectional faces i.e. faces which are perpendicular to the longitudinal axis.

The lateral surface area of prism A is calculated as,

[tex]\begin{gathered} LSA_A=2(5\times3)+2(5\times3)_{} \\ LSA_A=30+30 \\ LSA_A=60 \end{gathered}[/tex]

Similarly, the lateral surface area of prism A is calculated as,

[tex]\begin{gathered} LSA_B=2(3\times5)+2(5\times5)_{} \\ LSA_B=30+50 \\ LSA_B=80 \end{gathered}[/tex]

Clearly, prisms A and B have different values of lateral surface area.

So option A is the correct statement.

The total surface area is the sum of all the faces of the solid.

Since we have already calculated the LSA i.e. sum of area of 4 faces of the prism, we can add the area of the two remaining cross sectional faces to get the total area.

The total cross section area of prism B is calculated as,

[tex]\begin{gathered} A_B=2(5\times3) \\ A_B=30 \end{gathered}[/tex]

So the total surface area of prism B becomes,

[tex]\begin{gathered} TSA_B=LSA_B+A_B_{} \\ TSA_B=80+30 \\ TSA_B=110 \end{gathered}[/tex]

The total surface area of prism B is 110 sq. cm.

So option B is also correct.

Note that we have already found that the lateral surface area of prism A is 60 sq. cm.

Therefore, option C is also correct.

The total cross section area of prism A is calculated as,

[tex]\begin{gathered} A_A=2(3\times5) \\ A_A=30 \end{gathered}[/tex]

So the total surface area of prism A becomes,

[tex]\begin{gathered} TSA_A=LSA_A+A_A \\ TSA_A=60+30 \\ TSA_A=90 \end{gathered}[/tex]

The total surface area of prism A is 90 sq. cm.

It is oberved that prism B has a larger surface area.

So, option D is also correct.

Hence, we can conclude that all the given statements are correct.

According to the table, there are 270 one-headed in total, and there are 500 Jolos, we just have to subtract to find the total of two-headed Jolos

[tex]500-270=230[/tex]

There are 230 two-headed Jolos.

Now, we subtract the total of two-headed Jolos and the two-headed purple Jolos to find the total green.

[tex]230-125=105[/tex]

There are 105 two-headed green Jolos.

At last, we have to sum the number of one-headed green Jolos and the two-headed green Jolos,

What is meant by set-builder notation?

A set can be represented by its elements or the properties that each of its members must meet can be described using set-builder notation.

Set-builder notation is a mathematical notation for defining a set by enumerating its elements or by specifying the properties that each of its members must satisfy. It is used in set theory and its applications to logic, mathematics, and computer science.

Let the given inequality be 2x+1 < 27

Subtract 1 from both sides, we get

-2x+1-1 < 27-1

Simplifying the above equation, we get

-2 x < 26

Multiply both sides by - 1 (reverse the inequality)

(-2 x)(-1) > 26(-1)

Simplifying the above equation, we get

2x > -26

Divide both sides by 2

[tex]$\frac{2 x}{2} > \frac{-26}{2}[/tex]

Julian is decorating the outside of a box in the shape of a right rectangular prism. Thefigure below shows a net for the box.

Answers

The surface area of the box equals the sum of the surface area of each of its parts.

And the area of each rectangle that form the box is found by multiplying the width by the height of that rectangle.

We have two ractangles with sides 7 ft and 10 ft. So the area of each one is:

7 ft * 10 ft = 7 * 10 * ft * ft = 70 ft²

Since there's two of this rectangle, their areas sum up to

2 * 70 ft² = 140 ft²

Now, we also have two rectangles with sides 7 ft and 14 ft (the second and the fourth rectangles from left to right in the image). So, their areas sum up to:

2 * (7 ft * 14 ft) = 2 * (98 ft²) = 196 ft²

Finally, we also have two rectangles with sides 10 ft and 14 ft. Then, their area together is:

2 * (10 ft * 14 ft) = 2 * (140 ft²) = 280 ft²

Therefore the total surface area of the box is the sum:

140 ft² + 196 ft² + 280 ft² = 616 ft²

Find the volume of the pyramid. Round your answer to the nearest tenth.16 in.5 in.3 in.The volume of the pyramid isin?

Answers

Recalls that the formula for the volume of a pyramid is given by the product of the area of its base times the height, and all of that divided by 3

Then we start by calculating the area of the base:

Since the base is a rectangle of 3in by 5in, then its area is 15 square inches.

Now this area times the pyramid's height and divided by 3 gives:

Volume = AreaBase x Height / 3

Volume = 15 x 16 / 3 = 80 in^3 (eighty cubic inches)

Then, please just type the number 80 in the provided box (notice that the cubic inches unit is already written on the right of it.

Consider similar figure QRS and TUV below Where QRS is the pre image of TUV.Part A: What is the scale factor ? Part B:Find the the length of RS.​

Part A

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

so

In this problem

we have that

QS/TV=QR/TU=RS/UV

that means, that the scale factor is

scale factor=TV/QS

substitute the given values

scale factor=2.8/7=0.4

scale factor=0.4

Part B

Find the the length of RS

we have that

The length of RS is equal to the length of UV divided by the scale factor

Write a explicit formula for the given recursive formulas for each arithmetic sequence

9,15,21,27 and 7,0,-7,-14

Answers

In arithmetic progression, 9,15,21,27,33,39 is a₅ and    a₆ .

What is arithmetic progression?

A series of numbers is called a "arithmetic progression" (AP) when any two subsequent numbers have a constant difference. It also goes by the name Arithmetic Sequence.

a₁ = 9

a₂ = 15

a₃ = 21

Notice that a₂ - a₁ = 6 and a₃ - a₂ = 6

We can deduce that aₙ₊₁ = aₙ + 6

We can test this on the 4th term : a₄ should equal  21  + 6 = 27

Since this checks out we can say that the sequence is an arithmetic progression with a common difference of 6.

a₅ = 27 + 5 = 33

and

  a₆ = 33 + 6 = 39

7,0,-7,-14

find the common difference by substracting any term in the sequence from the term that comes after it.

 a₂ - a₁  = 0 - 7 = -7

 a₃ - a₂ = -7 - 0 = -7

 a₄ - a₃ = -14 - -7 = -7

the difference of the sequence is constant and equals the difference between two consecutive terms.

  d = -7

[tex]n=\frac{416ft^2}{50ft^2}=8.32[/tex]

It means that 8.32 rolls are needed to cover the bedroom. You will have to buy 9 rolls.

Sarina throws a ball up into the air, and it falls on the ground nearby. The ball's height, in feet, is modeled by the function ƒ(x) = –x2 – x + 3, where x represents time in seconds. What's the height of the ball when Sarina throws it?Question 12 options:A) 1 footB) 3 feetC) 4 feetD) 2 feet

Answers

Answer:

3 feet

Explanation:

We are told from the question that the ball's height, in feet, is modeled by the below function;

[tex]f(x)=-x^2-x+3[/tex]

where x = time in seconds

To determine the height of the ball when Sarina throws the ball, all we need to do is solve for the initial height of the ball, i.e, the height when x = 0. So we'll have;

[tex]\begin{gathered} f(0)=-(0)^2-(0)+3 \\ f(0)=3\text{ f}eet \end{gathered}[/tex]
