Use the figures below. What is the ratio of AD to JM?
A.2/3
B.6/5
C.3/2​

Answer:

7.64 in.

Step-by-step explanation:

The diameter of the circle whose circumference is 24 inches is 7.654 inches.

A circle is a two-dimensional object made up of points that are spaced out from a given point (center) on the plane by a fixed or constant distance (radius).

Given:

The circumference of the circle, C = 24 inches,

Calculate the radius of the circle as shown below,

Circumference = [tex]2\pi r[/tex]

C = 2 × π r

r = 24 / 2π

r = 3.819

r = 3.82 inches

Calculate the diameter as shown below,

Diameter = 2 × r

Diameter = 2 × 3.82

Diameter = 7.639 inches

Thus, the diameter is 7.64 inches.

Answer:

[tex]Length =\frac{25}{4 + \pi}[/tex] and [tex]Width = \frac{50}{4+\pi}[/tex]

Step-by-step explanation:

This question is better understood with an attachment.

See attachment for illustration.

Given

Represent Perimeter with P

[tex]P = 25ft[/tex]

Required

Determine the dimension of the rectangle that maximizes the area

First, we calculate the perimeter of the rectangular part of the window.

From the attachment, the rectangle is not closed at the top.

So, The perimeter would be the sum of the three closed sides

Where

[tex]Width = 2x[/tex]

[tex]Length = y[/tex]

So:

[tex]P_{Rectangle} = y + y + 2x[/tex]

[tex]P_{Rectangle} = 2y + 2x[/tex]

Next, we determine the circumference of the semi circle.

Circumference of a semicircle is calculated as:

[tex]C = \frac{1}{2}\pi r[/tex]

From the attachment,

[tex]Radius (r) = x[/tex]

So, we have:

[tex]C = \frac{1}{2}2\pi * x[/tex]

[tex]C = \pi x[/tex]

So, the perimeter of the window is:

[tex]P = P_{Rectangle} + C[/tex]

[tex]P =2y + 2x + \pi x[/tex]

Recall that: [tex]P = 25[/tex]

So, we have:

[tex]25 =2y + 2x +\pi x[/tex]

Make 2y the subject

[tex]2y = 25 - 2x - \pi x[/tex]

Make y the subject:

[tex]y = \frac{25}{2} - \frac{2x}{2} - \frac{\pi x}{2}[/tex]

[tex]y = \frac{25}{2} - x - \frac{\pi x}{2}[/tex]

Next, we determine the area (A) of the window

A = Area of Rectangle + Area of Semicircle

[tex]A = 2x * y + \frac{1}{2}\pi r^2[/tex]

[tex]A = 2xy + \frac{1}{2}\pi r^2[/tex]

Recall that

[tex]Radius (r) = x[/tex]

[tex]A = 2xy + \frac{1}{2}\pi x^2[/tex]

Substitute [tex]\frac{25}{2} - x - \frac{\pi x}{2}[/tex] for y in [tex]A = 2xy + \frac{1}{2}\pi x^2[/tex]

[tex]A = 2x(\frac{25}{2} - x - \frac{\pi x}{2}) + \frac{1}{2}\pi x^2[/tex]

Open Bracket

[tex]A = 2x * \frac{25}{2} - 2x * x - 2x * \frac{\pi x}{2} + \frac{1}{2}\pi x^2[/tex]

[tex]A = 25x - 2x^2 - \pi x^2 + \frac{1}{2}\pi x^2[/tex]

[tex]A = 25x - 2x^2 - \frac{1}{2}\pi x^2[/tex]

To maximize area, we have to determine differentiate both sides and set A' = 0

Differentiate

[tex]A' = 25 - 4x - \pi x[/tex]

[tex]A' = 0[/tex]

So, we have:

[tex]0 = 25 - 4x - \pi x[/tex]

Factorize:

[tex]0 = 25 -x(4 + \pi)[/tex]

[tex]-25 =-x(4 + \pi)[/tex]

Solve for x

[tex]x = \frac{-25}{-(4+\pi)}[/tex]

[tex]x = \frac{25}{4+\pi}[/tex]

Recall that

[tex]Width = 2x[/tex]

[tex]Width = 2(\frac{25}{4+\pi})[/tex]

[tex]Width = \frac{50}{4+\pi}[/tex]

Recall that:

[tex]y = \frac{25}{2} - x - \frac{\pi x}{2}[/tex]

Substitute [tex]\frac{25}{4+\pi}[/tex] for x

[tex]y = \frac{25}{2} - (\frac{25}{4+\pi}) - \frac{\pi (\frac{25}{4+\pi})}{2}[/tex]

[tex]y = \frac{25}{2} - (\frac{25}{4+\pi}) - \frac{\frac{25\pi}{4+\pi}}{2}[/tex]

[tex]y = \frac{25}{2} - (\frac{25}{4+\pi}) - \frac{25\pi}{4+\pi} * \frac{1}{2}[/tex]

[tex]y = \frac{25}{2} - \frac{25}{4+\pi} - \frac{25\pi}{2(4+\pi)}[/tex]

[tex]y = \frac{25(4+\pi) - 25 * 2 - 25\pi}{2(4 + \pi)}[/tex]

[tex]y = \frac{100+25\pi - 50 - 25\pi}{2(4 + \pi)}[/tex]

[tex]y = \frac{100- 50+25\pi - 25\pi}{2(4 + \pi)}[/tex]

[tex]y = \frac{50}{2(4 + \pi)}[/tex]

[tex]y = \frac{25}{4 + \pi}[/tex]

Recall that:

[tex]Length = y[/tex]

So:

[tex]Length =\frac{25}{4 + \pi}[/tex]

Hence, the dimension of the rectangle is:

[tex]Length =\frac{25}{4 + \pi}[/tex] and [tex]Width = \frac{50}{4+\pi}[/tex]

The ratio of their volumes is not the same 4:1, but [tex](4:1)^3[/tex] = 64:1.

Step-by-step explanation:

Measurements in Similar Figures

In similar figures, if the ratio of any of these corresponding lengths is expressed as a:b then the ratio of the other corresponding lengths can also be expressed as a:b.

In similar figures, if the ratio of any of these corresponding lengths is expressed as a:b then the ratio of the areas can be expressed as (a:b)^2 and the ratio of the volumes can be expressed as (a:b)^3.

We are given the ratio of the sides of two similar prisms as 4:1. The ratio of their volumes is not the same 4:1, but [tex]\mathbf{(4:1)^3}[/tex] = 64:1.

Answer:

$8333.3

Step-by-step explanation:

The problem here is to find the principal that will yield an interest of $500 in a year at a rate of 6%.

   Interest  = [tex]\frac{PRT}{100}[/tex]  

P is the principal

R is the rate

T is the time

The time is 1 year;

      500  = [tex]\frac{P x 6 x 1}{100}[/tex]

           6P = 50000

             P  = [tex]\frac{50000}{6}[/tex]   = $8333.3

Answer:x>5

Step-by-step explanation:

The correct answer is x=5

Here is the soulution:

Add 8 to both sides of the equation. x = −3 + 8

Add −3 and 8.

That equals x = 5.

Step-by-step explanation:

24=3n-15 or,25+15=3n or,39=3n or,39/3=n or,n=13 therefore the value of n is 13. I think this answer is helpful for you

Answer: n = 13

Step-by-step explanation:

24=3(n-5) - First  distribute the 3 to the n and the 5. Which you would than get 3n and -15

24=3n-15 - Now add the 15 to both sides which would cause it to cancel out on the left side of the equal side.

39=3n - Now divide the 3 from 3n on both sides of the equal side.

n=13 - Once you do that you will get n = 13. That is your answer!

Answer:

10

Step-by-step explanation:

so x=true/false questions

y=multiple-choice questions

2x+4y=100

2x=y

plug in 2x for y in the first equation

2x+4(2x)=100

10x=100

x=10

y=20

The total questions would include 10 true/false questions and 20 multiple-choice questions.

We have Mr. Dudley who is writing a test for his mathematics class. The test will have true/false questions worth 2 points each and multiple-choice questions worth 4 points each for a total of 100 points. He wants to have twice as many multiple-choice questions as true/false questions.

We have to determine how many true/false questions and multiple-choice questions will be on the test.

The modelling of equation is done to derive a mathematical relation among the terms defined in a mathematical statement.

According to the question -

Assume that the number of true/false questions be x.

Assume that the number of multiple-choice questions be y.

Then -

y = 2x

Points for each true/false questions - 2 points

Points for each multiple-choice questions -  4 points

Total points of test = 100 points

Now,

Model the equation on the basis of above information -

2x + 4y = 100

2x + 4 (2x) = 100

2x + 8x = 100

10x = 100

x = 10

Therefore -

y = 2x = 2 x 10 = 20

Hence, the total questions would include 10 true/false questions and 20 multiple-choice questions.
