Answer:

238

Step-by-step explanation:

First, you must find the ratio between the one measurement of the larger octagon and the smaller octagon. Just divide 28 by 4 to get 7. This is what you have to multiply the perimeter by to get the larger octagon's perimeter.  34 times 7 equals 238. There are multiple ways to do this problem but this way is the simplest.

The expression of the volume of the cone that is π/4 of the volume of the pyramid, is expressed as: [tex]\mathbf{\frac{\pi}{4} (\frac{4r^2h}{3} )}[/tex].

Volume of a pyramid = 1/3(length)(width)(height)

Find the volume of the pyramid in the image given:

Volume of the pyramid = 1/3(2r)(2r)(h)

Volume of the pyramid = 4r²h/3

We are given that the volume of the cone is π/4 of the volume of the pyramid.

Therefore, the expression that represents the volume of the cone would be: [tex]\mathbf{\frac{\pi}{4} (\frac{4r^2h}{3} )}[/tex]

Answer:

50

Step-by-step explanation:

to find the value of x use "sinerule"

sinx/13= Sin90/17

sinx = sin90×13/17

sinx= 14/17

sinx= 0.764705882

X= SIN^-1(0.764705882)

X = 49.888

X= 50

Answer:

we know that sum of two complementary angles always equals to 90°

now ∠ABC and ∠CBD are complementary which means ∠ABC + ∠CBD = 90

∠ABC = 35° given

so ∠CBD = 90° - ∠ABC = 90° - 35° = 55°

therefore hence proved ∠CBD = 55°

Answer:

y = [tex]\frac{1}{2} x\\[/tex]+5

Step-by-step explanation:

Y-intercept 5

Answer:

y- intercept = 5

Step-by-step explanation:

to find the y- intercept let x = 0 in the equation and solve for y

this relies on the fact that when the line crosses the y- axis the x- coordinate is zero, then

0 - 2y = - 10 , that is

- 2y = - 10 ( divide both sides by - 2 )

y = 5

then y- intercept = 5

Option A is true because the sum of angles in a triangle is 180, so we can rule that one out immediately.

We can solve for x for the other 3 options by setting up this equation:

7x+2 + 4x+7 + 8x = 180 | Simplify

19x + 9 = 180 | Subtract 9

19x = 171 | Divide by 19
x=9

Now we can substitute x into all the values:
<J = 7x+2 = 65
<L = 4x+7 = 43
<K = 8x = 72

Looking at the options again, we can see that A, B, and D are true, leaving C to be false.

Answer:

4√33/33

Step-by-step explanation:

Solution,

Here,

sinθ=4/7

p/h=4/7

b=?

Now using Pythagoras theorem,

[tex]\hookrightarrow h^{2} =p^{2} +b^{2} \\\\\hookrightarrow (7)^{2} =(4)^{2} +b^{2}\\\\\hookrightarrow 49-16=b^{2} \\\\\hookrightarrow b=\sqrt{33}[/tex]

Again,

tanθ=p/b

[tex]tan\theta=\frac{4}{\sqrt{33} } \\\\tan\theta=\frac{4}{\sqrt{33} } \times \frac{\sqrt{33} }{\sqrt{33} } \\\\tan\theta=\frac{4\sqrt{33} }{33}[/tex]

According to the question ,

Sin θ = 4/7

We know that , Sin θ = Perpendicular/Hypotenuse

So , by Pythagoras theorem

Hypotenuse² = Perpendicular ² + Base ²

7² = 4² + x²

49-16 = x²

√33 = x

5.7 = x

So , the base is 5.7 units (approx)

Tan θ = Perpendicular/base

Tan θ = 4/5.7

Answer:

This cannot be explained properly by me, but the answer is 4 3/4*1 1/3 divided by (7 1/2-1 1/6). I just did a lot of trial and error

Step-by-step explanation:

The mathematical operations used [tex](4.75/7.50) * 1.17 * 1.34[/tex].

An operation exists as a mathematical action. Addition, subtraction, multiplication, division, and calculating the root exist all instances of a mathematical operation.

Given: 4 3/4 _ 7 1/2 _ 1 1/6 _ 1 1/3 = 1 or

4 3/4 _ 7 1/2 _ 1 1/6 _ 1 1/3 = 1

Convert mixed fraction into a proper fraction we have

[tex](19/4) * (15/2) * (7/6) * (4/3) = 1[/tex]

Now convert the proper form of the fraction into a decimal

[tex]$4.75 * 7.50 * 1.16 * 1.34[/tex]

Inserting operation signs, then we get

[tex]= (4.75/7.50) * 1.17 * 1.34[/tex]

= 0.99294

= 1 (approximately)

Therefore, the correct answer is [tex](4.75/7.50) * 1.17 * 1.34[/tex].
