Step-by-step explanation

If breadth =x

Length =2x

Perimeter = 2x +x +2x+x

36=6x

X=6

Therefore breadth =6

Length =12

The question asks about finding the length and width of a rectangle given its perimeter. By setting up and solving an equation, we found that the rectangle's width is 6 inches, and its length is 12 inches.

Given that the length of a rectangle is 2 times its width, and the perimeter of the rectangle is 36 inches, we are asked to find the length and width of the rectangle. We can start by defining the width as 'w' and the length as '2w'. The formula for the perimeter of a rectangle is 2(length + width). We can substitute our definitions of length and width into this formula to get 2(2w + w) = 36. Simplifying this gives 3w = 18, so the width is 6 inches. Therefore, the length is 2 × 6 = 12 inches.

B=5 units that is the answer

1) The sum of an Octagon is 1080°

And all it's sides are congruent (same size, same angle measure)

And an Octagon has 8 sides

So do,

1080 ÷ 8 = 135°

Each side equals to 135°

2) A triangle adds up to 180°.

We have one angle that's 45° and another angle that has a little □ in it.

That little square (□) is called a right angle which = 90°

So do

90 + 45 = 135

180 - 135 = 45

So the value of x is 45°

Answer:

"The diameter of the bacterium is 10 times greater than that of the virus."

Step-by-step explanation:

Size of bacteria is 10^-6

Size of virus is 10^-7

Definitely the bacteria is larger. How many times larger? We find that by dividing the diameter of bacterium by the diameter of virus.

Let's do this:

[tex]\frac{10^{-6}}{10^{-7}}\\=\frac{0.000001}{0.0000001}\\=10[/tex]

Hence, the bacterium is 10 times larger than the virus

Answer:

I got A) "The diameter of the bacterium is 10 times greater than that of the virus."

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]a_{1} = 8\\a_{9} = 360 = a_{1} \cdot r^9 = 8 \cdot r^9\\r = \sqrt[9]{\frac{360}{9} }  \cong 1.53[/tex]

By the formula of a geometric series:

[tex]S_{n} = a \cdot \frac{1-r^n}{1-r} => S_{19} = 8 \cdot \frac{1-1.53^{19}}{1-1.53}  = 6091.54[/tex]

Answer:

r = 1.6

a19 = 37800

Step-by-step explanation:

First term [tex] a_1 = 8 [/tex] and [tex] a_9 = 360 [/tex] of a geometric sequence and we are to find the 19th term along with the common ratio for this sequence.

We know that the general term of a Geometric Sequence is given by:

[tex]a_n= a \cdot r^{n-1}[/tex]

where [tex]a_n[/tex] is the nth term, [tex]a[/tex] is the first term, [tex]n[/tex] is the number of terms and [tex]r[/tex] is the common ratio.

Substituting the given values in the above formula to get:

[tex]360 = (8)*(r)^(9-1)[/tex]

[tex]360 = 8*(r^8)[/tex]

[tex]r^8 = \frac{360}{8}[/tex]

[tex]r^8 = 45[/tex]

r = 1.6

Finding the 19th term:

[tex]a_n= a \cdot r^{n-1}[/tex]

[tex]a_{19}= 8 \cdot 1.6^{19-1}[/tex]

a19 = 37800

The answer is: Angle B is 30°

Since we know that both sides, a and b are equal to 2, and angle A is equal to 30°, we can conclude that angle B is also equal to 30°. Also, we can know that the other angle (C) will be equal to 120° since the sum of all the angles in a triangle will be always equal to 180°.

The world population is approximately 23 times larger than the population of the United States.

The question is asking how many times larger the world population is compared to the population of the United States. You can determine this through division. In this case,
6.9 × 109 (the world population) divided by 3 × 108 (the US population) equals approximately 23. This means that the world population is approximately 23 times larger than the population of the United States.

https://brainly.com/question/12287830

#SPJ3

The answer is expressed in standard notation as 23.

To calculate how many times larger the world population is compared to the United States, we divide the world population by the population of the United States. Given the world population as 6.9 × 10^9 people and the U.S. population as 3 × 10^8 people, we perform the following calculation:

6.9  × 10^9 ÷ 3 × 10^8 = 23 times larger.

When we divide these two numbers, we subtract the exponents (since the bases are the same) resulting in 10^1, which is just 10. Multiply the non-exponential part: 6.9 ÷ 3, which equals 2.3. Therefore, 2.3 × 10 tells us that the world population is 23 times larger than the population of the United States. To write this in standard notation, we simply say the world population is 23 times larger.

Answer: [tex]6.185in^3[/tex]

Step-by-step explanation:

The formula for calculate the volume of a cylinder is:

[tex]V_{cylinder}=\pi r^2h[/tex]

r is the radius of the cylinder and h is the height of the cylinder.

Given the diameter of 3 inches, calculate the radius of the cylinder with:

[tex]r=\frac{d}{2}[/tex] (Where d is the diameter)

 [tex]r=\frac{3in}{2}=1.5in[/tex]

Knowing the height and the radius, you can calculate the volume of the entire can of tuna:

[tex]V_{can}=\pi (1.5)^2(1.75in)=12.37in^3[/tex]

As you want to know the cubic inches of tuna that are in the can (volume of tuna), and you know that the can is half full, then:

[tex]V_{tuna}=\frac{V_{can}}{2}\\\\V_{tuna}=\frac{12.37in^3}{2}\\\\V_{tuna}=6.185in^3[/tex]

The given graph show a proportional relationship that it's modelled by a linear equation. We can make all the process to calculate the equation that belongs to that behaviour. We just have to find the slope:

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}} \\m=\frac{18}{6}=3[/tex]

Using the slope interception formula: [tex]y=mx+b[/tex]

[tex]y=3x+0[/tex]

Because the interception with the vertical axis is null, so the equation would be:

[tex]y=3x[/tex]

Therefore the answer is C.

➷ The formula for circumference is [tex]\pi d[/tex]

Half this to find the radius

10/2 = 5

It would be figure B.

2) [tex]\pi d = 37.68[/tex]

Divide both sides by [tex]\pi[/tex]:

d = 11.99 (consider this to be 12)

Divide by 2 to find the radius:

12/2 = 6

It would be figure C.

3) area = [tex]\pi r^2[/tex]

Answer: OPTION A

Step-by-step explanation:

Apply the formula for calculate the distance between two points to know the value of the diameter of the circle:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\D=\sqrt{(-5-(-5))^2+(-2-6)^2}\\D=8[/tex]

The equation of the circle is standard form is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where r is the radius and (h,k) is the point of the center of the circle.

As we know the diameter, we can find the radius:

[tex]r=\frac{8}{2}=4[/tex]

Substitute it into the equation:

[tex](x-h)^2+(y-k)^2=(4)^2[/tex]

[tex](x-h)^2+(y-k)^2=16[/tex]

Here Angle E corresponds and is congruent to Angle R in these congruent triangles.

Angle D is congruent and corresponds to Angle K for these congruent triangles.

Angle O is equal to Angle O as they are vertical angles across a vertex.

Congruent triangles, in mathematics, are triangles that are of the same size and shape, meaning their corresponding sides and angles are equal. An example would be two triangles each with sides of 3, 4, and 5 units.

In mathematics, specifically in geometry, congruent triangles are defined as triangles that have the same size and shape. This means that their corresponding sides are of equal length, and their corresponding angles are of equal measure. The concept of congruence is important in many aspects of geometry, including the study of shapes, symmetry, and transformations.

If we have two triangles, Triangle A (with sides of 3, 4, and 5 units respectively) and Triangle B (with sides of 3, 4, and 5 units as well), these two triangles are congruent, as the lengths of their corresponding sides are equal. You could rotate, flip or move one to coincide exactly with the other, showcasing their congruency.
