Volume= 1416.9 ft^3

Answer 2

The amount of concrete that is required to fill the fountain is given as 1433.61 ft³. None of the options is correct.

What is a right circular cylinder?

A right circular cylinder is a three dimensional figure having its base and top as a circle and the height is perpendicular to circular base. The volume is given as V = πr²h.

The height of fountain is 5 feet.

And, the diameter is 19 feet.

Then, the radius is given as 19/2 = 9.5 feet.

The amount of the concrete filled is equivalent to the volume of cylinder given as,

Plug h = 5 and r = 9.5 in V = πr²h as below,

⇒ V = 3.14 × 9.5² × 5 = 1433.61

Hence, the amount of concrete is given as 1433.61 ft³.

The correct net of the prism is net A and the surface area of the prism is 510 square inches

How to determine the surface area

To calculate the area of the triangular prism, we make use of the net A

Start by calculating the area of the rectangle.

The dimension of the rectangle is (5 + 12 + 13) by 15

So, the area of the rectangle is:

[tex]Area = (5 + 12 + 13) * 15[/tex]

[tex]Area = 450[/tex]

Next, calculate the area of the two congruent triangles of base 5 and height 12

[tex]Area = 2 * 0.5 * (5 * 12)[/tex]

[tex]Area = 60[/tex]

Sum both areas

[tex]Total = 450 + 60[/tex]

[tex]Total = 510[/tex]

Hence, the surface area of the prism is 510 square inches

An economy package of cups has 200 green cups. If the green cups are 10% of the total package, how many cups are in the package?

Answers

Final answer:

Set up a proportion where 10% of the total number of cups equals 200 green cups, then calculate to find that there are 2000 cups in the entire package.

Explanation:

To find the total number of cups in the package when 200 green cups represent 10% of the total, we can set up a simple proportion. Here, 10% corresponds to the number of green cups we know about. We need to find 100% to discover the total number of cups in the package.

The proportion we'll set up is:

10% / 200 cups = 100% / x cups

To solve for x (the total number of cups), we will divide 200 cups by 10% to find the value of 1% and then multiply by 100%:

1% of total = 200 cups / 10

x (total cups) = (200 cups / 10) × 100

Perform the calculation:

x = 20 cups × 100

x = 2000 cups

So, there are 2000 cups in the total package.

The distance around a circle is 56.55 meters long. What is the diameter of the circle?

Answers

the answer is 113.1 I hope it helps you and I hope this is correct.

Answer: Diameter of circle = 18m

Explanation:

Given that distance around a circle is = 56.55 meter

The distance around a circle on the other hand is called the circumference .

That means Circumference = 56.55 m

We know the formula of circle's circumference= 2πr

where r is the radius and 2r is diameter of the circle

So,

2πr = 56.55

divide by π both the side

2r = [tex] \frac{56.55*7}{22} [/tex]

Value of π = [tex] \frac{22}{7} [/tex]

2r = 17.993 ≈ 18 m

Diameter of circle = 18m

What sum of money will yield a simple interest of Rs.1155 in 3 years 6 months at 11% per annum .

Answers

Answer:

Rs.833.94

Step-by-step explanation:

To solve for the sum of money or principal, we use the formula:

[tex]P=\dfrac{A}{1+rt}[/tex]

The current variables we have are:

A = Rs.1,155

r = 11% or 0.11

t = 3.5

Now let's plug the variables into the formula.

[tex]P=\dfrac{A}{1+rt}[/tex]

[tex]P=\dfrac{1,155}{1+(0.11)(3.5)}[/tex]

[tex]P=\dfrac{1,155}{1+0.385}[/tex]

[tex]P=\dfrac{1,155}{1.385}[/tex]

Jeremy's statement that triangle ABD is congruent to triangle CBD by the SAS congruence postulate is incorrect.

If we are also given that AD is congruent to CD, then we can use the SSS congruence postulate to prove that triangle ABD is congruent to triangle CBD.

Answer to part (a)

I disagree with Jeremy's statement that triangle ABD is congruent to triangle CBD by the SAS congruence postulate.

The SAS congruence postulate states that two triangles are congruent if they have two pairs of corresponding sides congruent and the included angle congruent.

In this case, we have two pairs of corresponding sides congruent (AB = BC and AD = CD, since B is the midpoint of AC). However, we are not given that the included angle (angle ABD) is congruent to angle CBD.

Therefore, we cannot use the SAS congruence postulate to prove that triangle ABD is congruent to triangle CBD.

Answer to part (b)

If we are also given that AD is congruent to CD, then we can use the SSS congruence postulate to prove that triangle ABD is congruent to triangle CBD.

The SSS congruence postulate states that two triangles are congruent if they have three pairs of corresponding sides congruent.

In this case, we have three pairs of corresponding sides congruent (AB = BC, AD = CD, and BD = BD). Therefore, we can use the SSS congruence postulate to prove that triangle ABD is congruent to triangle CBD.

The image on a movie poster was shrunk to make the DVD cover art for the movie, so that the cover art is a scale image of the poster. The poster is 36 inches wide, and the DVD cover art is 6 inches wide. If the diagonal of the poster is 4 feet, what is the diagonal of the DVD cover art?

Answers

Please see the attached image for a visual representation of our scale factor. We can set up this proportion by taking the DVD cover and poster values and placing them in fractions. Cross multiply and divide to solve for x.

The first thing we need to do is find the proportionality constant [tex]k[/tex]. Since we now that the width of a movie poster was shrunk from 36 inches to 6 inches to make the DVD cover, [tex]k= \frac{36}{6} =6[/tex]; therefore, the width of poster was shrunk, in other words divided, by a factor of 6.
Now that we have our proportionality constant lest apply it to the diagonal of the poster to find the diagonal of the DVD cover. But notice that the diagonal of the poster is in feet not inches, so we need to convert 4 feet to inches first. Remember that 1 foot = 12 inches, so lets use that proportion to set up our conversion fraction:
[tex](4feet)( \frac{12inches}{1 foot} )= 48inches[/tex]
The only thing left now is shrunk, divide, the diagonal by our proportionality constant [tex]k[/tex]
[tex] \frac{48}{k} = \frac{48}{6} =8[/tex]

We can conclude that If the diagonal of the poster is 4 feet, the diagonal of the DVD cover will be 8 inches.

Explain the advantage of creating a linear function from a set of data; why bother to do this?

Answers

If the data you list has a linear relationship, then creating a linear function from the data might be helpful because it would define the relationship and help you to answer questions related to it that the data you have at present might not.

Here is an example. Height and shoe size have a linear relationship. Let's say you plot the point (height in inches, shoe size in US women's sizes) for 50 people or so. You would see a strong linear relationship. The points wouldn't make a perfect line but very close to it. As height increases so does shoe size and it does so in a linear way. Now if we call the height h and the shoe size s then we would have an equation that relates h and s. So that if we wanted to know the shoe size of someone 96 inches (8 feet high) tall we could get that (or very close to it) from the equation even if there was no one in our sample that was that tall. Similarly we could solve for height if we knew shoe size.

A navigator plots the course a plane is currently traveling. The plane is 300 miles from its destination. If it continues on its current course it will travel 325 miles and end up 125 miles due south of its destination. To the nearest degree, how many degrees is the plane off course?

Answers

We have to use the rule of cosx° to solve this problem. Attached is a diagram of the navigator's course for the plane. It is similar to the shape of a triangle. We know the plane is 300 miles from its destination, so that will be one of the sides. On the current course, it is 325 miles from its destination, so that will be another one of the sides. The last side is 125 because that is the distance between the destination and the anticipated arrival. Cosx° is what we are looking for.

To find how many degrees off course the plane is, we must use the rules of Cosx°, which is shown in the attached image.

The plane is approximately 23° off course.

Final answer:

The plane in question is approximately 23 degrees off course. This calculation is derived from the tangent function in trigonometry based on the distances given.

Explanation:

From the question, we understand that the plane is creating a right triangle due to its off-course direction. Using the Pythagorean theorem, the length of the hypotenuse, or the distance that the plane will travel, is 325 miles. The difference between the direct route (300 miles) and the off-course southern distance (125 miles) forms the two other sides of the triangle.

However, we're looking for the angle, not the sides. This is where trigonometry comes in. Specifically, the tangent function will be valuable here as it involves the opposite and adjacent sides of a right triangle (the off-course southern distance and the direct route distance). If we let the 'off-course' angle be θ, then we have:

Tan(θ) = (distance south / direct distance) = (125 miles / 300 miles)

In order to find the angle θ from this equation, we'll need to use the inverse tangent function.

θ = atan(125/300) = 22.61986495 degrees.

Therefore, to the nearest degree, the plane is approximately 23 degrees off course.
