a right rectangular prism is made with 8 small cubes. Each cube has an edge length of 1/5 inch.

What is the volume in cubic inches?

Answers

Final answer:

The volume of a right rectangular prism made from 8 small cubes with an edge length of 1/5 inch each is 8/125 cubic inches.

Explanation:

The question asks for the volume of a right rectangular prism made up of 8 small cubes, with each cube having an edge length of 1/5 inch. To find the volume of the right rectangular prism, we must first understand the volume of a single cube, which is found by multiplying the length, width, and height of the cube. Since each side of a cube is equal, the volume of one cube is (1/5 inch) × (1/5 inch) × (1/5 inch), which equals 1/125 cubic inches.

Next, the volume of the entire prism, which consists of 8 such cubes, is calculated by multiplying the volume of one cube by 8. Therefore, the total volume of the prism is (1/125 cubic inches) × 8, which equals 8/125 cubic inches.

A container is in the shape of a cylinder with a hemisphere on the top. The cylinder has radius 5 cm and height 8 cm. The hemisphere has the same radius as the cylinder.

What is the total surface area of the container? Give your answer in cm2 correct to 3 significant figures.

Answers

The total surface area is given by:

The base of the cylinderThe lateral surface of the cylinderThe surface of the hemishpere

The base of the cylinder is a circle with radius 5cm, so its area is

[tex]A=\pi r^2=25\pi[/tex]

The lateral surface of the cylinder is a rectangle whose base is the circumference of the base circle, and whose height is the height of the cylinder. So, its area is

[tex]A=b\cdot h=2\pi r\cdot h = 10\pi\cdot 8=80\pi[/tex]

Finally, the surface of a sphere is given by

[tex]A=4\pi r^2[/tex]

so, half that surface will be

[tex]A=2\pi r^2=50\pi[/tex]

And the total surface area will be the sum of the three areas:

[tex]A=25\pi+80\pi+50\pi = 155\pi[/tex]

Answer:

Total surface area of the figure[tex]=486.7cm^2[/tex]

Step-by-step explanation:

Total surface area of the figure= Surface area of cylinder + Area of the top hemisphere

[tex]r= 5cm\\\\h= 8cm[/tex]

Area of the cylinder with the side walls and the the bottom:

          [tex]A=(2*\pi* r*h)+(\pi *r^2)[/tex]

             [tex]=(2*3.14*5*8)+(3.14*5*5)\\\\ =251.2+78.5\\\\ = 329.7 cm^2[/tex]

Area of the top hemisphere:

                                               [tex]2*\pi *r^2[/tex]

                               [tex]=2*3.14*5*5[/tex]

  Area of the top hemisphere= [tex]157 cm^2[/tex]

Total surface area of the figure [tex]= 329.7+157\\\\[/tex]

D. Put one finger halfway between 1 and 2 on the x-axis, and put another finger at the 4 on the y-axis. Move the first finger up and the second finger to the right until they meet.

Answers

Option  A and D will not get to the required point

Step-by-step explanation:

Step 1 :

a)

Start at origin, go 112 units up and then go 4 unit to the right.

Starting at the origin, 112 units up gives y = 112

then 4 spaces to the right gives x = 4

So the point obtained is (4,112)

Hence option A will not get to the required point

Step 2 :

b)

Starting at the origin, go 4 spaces up and then 112 spaces to the right.

Starting at the origin , 4 spaces up gives y = 4

112 spaces to the right gives x = 112

So we get the point as (112,4)

Option B goes to the required point

Step 3:

c)

Starting at the origin, go 112 spaces to the right and then 4 spaces up.

Starting at the origin, 112 spaces to the right gives x = 112

4 spaces up gives y = 4

We get to the point (112,4)

Hence option C gets to the required point

Step 4:

d)

Doing the procedure in option D gives y = 4, and x as between 1 and 2

Hence this will not get to the required point

A 1,000 gallon pool (no top) with a rectangular base will be constructed such that the length of the base is twice the width. Find the dimensions (length, width, and height) of the pool that minimize the amount of material needed to construct it.

Answers

Answer:

W = 4.646 ft

L = 9.292 ft

H = 3.097 ft

Step-by-step explanation:

Let's say the L is the length, W is the width, and H is the height.

The volume of the pool is:

V = LWH

The area of the pool is:

A = LW + 2LH + 2WH

L = 2W, so substituting:

V = (2W)WH

V = 2W²H

A = (2W)W + 2(2W)H + 2WH

A = 2W² + 4WH + 2WH

A = 2W² + 6WH

Solving for H in the first equation and substituting into the second:

H = V/(2W²)

A = 2W² + 3V/W

Find dA/dW and set to 0.

dA/dW = 4W − 3V/W²

0 = 4W − 3V/W²

4W = 3V/W²

4W³ = 3V

W = ∛(¾V)

V = 1000 gallons or 133.7 ft³.

W = ∛(¾(133.7 ft³))

W = 4.646 ft

So L = 9.292 ft and H = 3.097 ft.

A mailbox on the street is 600 feet from the top of a building. From the mailbox looking up to the tops of that building and a second, taller building, the angle between the buildings is 67degrees. The tops of the buildings are 800 feet from each other. If the angle of elevation from the mailbox to the first building is 53 degrees and the taller building is 60 degrees, how tall is each building... Step by step explanation..Please..Thanks

Answers

Answer:

first building: 479.2 ftsecond building: 704.2 ft

Step-by-step explanation:

Label the mailbox viewpoint, the top of the first building, and the top of the second building points M, A, and B, respectively.

Consider the triangle MAB. You are told length MA is 600 ft, and length AB is 800 ft. Side AB is opposite the 67° angle at M, so we can use the Law of Sines to find other measures of that triangle. Specifically, we want to know the distance MB.

  sin(B)/MA = sin(M)/AB

  sin(B) = (MA/AB)sin(M) = 600/800·sin(67°) ≈ 0.690379

  B ≈ 43.66°

Then the angle at A is ...

  180° -67° -43.66° = 69.34°

and the side MB can be found from ...

  MB/sin(A) = AB/sin(M)

  MB = (sin(A)/sin(M))AB = sin(69.34°)/sin(67°)·800 ≈ 813.2 . . . feet

__

Now, label points on the ground below A and B as A' and B'. This problem is asking for the heights AA' and BB'. Each of these is opposite the angle of elevation to points A and B, respectively, so can be found using the sine relation:

  sin(elevation to A) = AA'/MA

  AA' = MA·sin(elevation to A) = 600·sin(53°) ≈ 479.2 . . . ft

Similarly, ...

  BB' = MB·sin(elevation to B) = 813.2·sin(60°) ≈ 704.2 . . . feet

The first building is 479.2 ft tall; the second is 704.2 ft tall.

each of five friends has X action figures in his or her collection. Each friend buys 11 more action figures. Now the five friends have a total of 120 action figures.write an equation that models this problem then solve

Answers

Answer:

Each friend has 13 actions

Step-by-step explanation:

Let x represent the actions of each friends

5friends will have 5x actions

And each friend has 11 more actions which means 5(11)=55

It means 5x+55

The total of their actions is 120

It can be written as 5x+55= 120

To solve

5x+55=120

Substrate 55 from both sides

5x=120-55

5x=65

X=65/5

x=13

Which each friend has 13 actions

Final answer:

To model the problem, the equation 5X + 5(11) = 120 is used. Solving this equation leads to finding that the original number of action figures each friend had is X = 13.

Explanation:

Initially, each of the five friends has X action figures in their collection. After purchasing 11 more action figures each, they collectively have a total of 120 action figures. To represent this problem, we can set up an equation where 5 times the original number of action figures per friend, plus 5 times 11 (because each friend buys 11 more), equals 120. Thus, the equation is:

5X + 5(11) = 120

To find the value of X, we need to solve the equation:

Multiply 5 times 11 to simplify the equation: 5X + 55 = 120

Subtract 55 from both sides of the equation: 5X = 120 - 55

Calculate the result on the right side: 5X = 65

Divide both sides by 5 to find X: X = 65 / 5

Thus, the original number of action figures each friend had is X = 13.

Which of the following is a solution of x^2 + 5x = -2?

Answers

Answer:

x= -0.4385 or -4.5615

Step-by-step explanation:

x²+5x+2=0

Using almighty formula;

a=1, b=5, c=2

x = [ -b± √( b^2 - 4ac)]/2a

x= -5±√(25-8)/2

x=(-5±4.123)/2

Therefore x=(-5+4.123)/2 or (-5-4.123)/2

x= -0.4385 or -4.5615

The solutions are [tex]\(x = \frac{{-5 + \sqrt{17}}}{2}\) and \(x = \frac{{-5 - \sqrt{17}}}{2}\).[/tex]

To find the solution of the equation [tex]\(x^2 + 5x = -2\), we need to solve for \(x\).[/tex]

Let's rearrange the equation to bring all terms to one side:

[tex]\[x^2 + 5x + 2 = 0\][/tex]

Now, we can solve this quadratic equation by factoring, completing the square, or using the quadratic formula. Let's use the quadratic formula:

[tex]\[x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}\][/tex]

In our equation, [tex]\(a = 1\), \(b = 5\), and \(c = 2\).[/tex]

[tex]\[x = \frac{{-5 \pm \sqrt{{5^2 - 4(1)(2)}}}}{{2(1)}}\]\[x = \frac{{-5 \pm \sqrt{{25 - 8}}}}{2}\]\[x = \frac{{-5 \pm \sqrt{{17}}}}{2}\][/tex]

So, the solutions are:

[tex]\[x_1 = \frac{{-5 + \sqrt{{17}}}}{2}\]\[x_2 = \frac{{-5 - \sqrt{{17}}}}{2}\][/tex]

Thus,  [tex]\(x = \frac{{-5 + \sqrt{{17}}}}{2}\) or \(x = \frac{{-5 - \sqrt{{17}}}}{2}\). These are the solutions to the equation \(x^2 + 5x = -2\).[/tex]
