Step-by-step explanation:

substract the index of the number

The value of V-E+F=2

Euler's polyhedron formula, V−E+F=2

A hexagonal prism has 8 faces, F=8

A hexagonal prism has 12 vertices, V=12

A hexagonal prism has 18 edges, E=18

So, 12−18+8=2

V-E+F=2 is Euler's polyhedron formula.

F=8 for a hexagonal prism with 8 faces

V=12 is the number of vertices in a hexagonal prism.

E=18 is the number of edges on a hexagonal prism.

So, 12−18+8=2

A hexagonal prism is a three-dimensional prism with two parallel ends that have the same size and form. The hexagonal prism has six parallelogram-shaped faces on its six sides. Regular hexagonal prisms and irregular hexagonal prisms are the two types of hexagonal prisms. A hexagonal prism is a polyhedron with 8 faces, 18 edges, and 12 vertices, with 6 faces in the shape of rectangles and 2 faces in the shape of hexagons.

48 persons make up a party. There are seven times more adults than children in the world. Males outnumber females two to one. If the party has five girls. The total number of male adults are15

The total number of people are in the party is equal to 48

Let the number of children be x

So, the number of adults in the party is equal to 7 x

x + 7 x =48 ( This is a linear equation)

So, the number of children in the comes to be 6

Number of adults in the party = 6 * 7 = 42

Now let number of males be y

So total number of females = 2 y

Y+2y = 48 ( This is a linear equation)

Y=16

Therefore, the number of males is 16 and number of females is 32

Number of children in the party is 6 and female child is equal to 5

Then, number of male children =6-5 = 1

So total males in the party is equal to 16

Adult males =total number of males - number of male children

=16 - 1 = 15

Hence the total number of male adults =15

The equation of the line is y = 5x + 35

The equation of a line can be represented in a slope intercept form as follows:

y = mx + b

where

Therefore, line that are parallel have the same slope.

Therefore, if line one slope is 5, then the slope of the unknown line will be 5.

Hence,

y = 5x + b

let's find the y-intercept using (-8, -5)

-5 = 5(-8) + b

-5 = -40 + b

b = -5 + 40

b = 35

Therefore, the equation of the line is y = 5x + 35

Mr Fishman's age is 47.

Let:

The difference between the older sister and younger sister's age: y - x = 20 equation 1

Mr Fishman's is 11 years less than twice his young sister's age: 2x - 11 = c equation 2

The difference between Mr Fishman and his older sister's age : y - c = 2

y  - 2 = c equation 3

Let equation 2 and 3 be equal : 2x - 11 = y - 2

2x - y = 11 - 2

2x - y = 9

-y + 2x = 9 equation 4

The two equations that would be used are:

y - x = 20 equation 1

-y + 2x = 9 equation 4

Add both equations together

x = 29

Substitute for x in equation 1

y - 29 = 20

y = 29 + 20

y = 49

y - c = 2

49 - c = 2

  thousands place: 4th one to the left of the decimal point, 1000.

Step-by-step explanation:

You want the number place of a 1 that has a value 100 times that of the 1 in 314.

The digit 1 in the number 314 is in the "tens place." It signifies 1 ten is part of the value of the number 314.

The value of a digit 1 that is 100 times that will be ...

  10 × 100 = 1000

That is, the digit will be found in the "thousands place," two digits to the left of the location in the number 314.

The 1 with a value of 1000 is written in the thousands place, the 4th place to the left of the decimal point.

Answer:

Step-by-step explanation:

It takes Layla 45 minutes to make 9 bracelets on her own.

45 divided by 9 equals 5. It takes Layla 5 minutes to make one bracelet.

Layla and Amelia can make 9 bracelets in 20 minutes.

20 divided by 9 equals 2 and 2/9.

5 - 2 2/9= 2 7/9

2 7/9 times 9 equals 25

Amelia can make 9 bracelets in 25 minutes

So it takes Layla 56 minutes to make 9 ( 45 divided by 9 = 5) so that means in 20 minutes Layla will make 4 bracelets.

this means it will piece together as Layla would make 4 while Amelia makes 5. So i think on Amelia's own it'll take her 40 minutes.

[tex]\textsf{d)} \quad \dfrac{5}{6}, \quad \dfrac{25}{6}[/tex]

Step-by-step explanation:

Given:

[tex]12 \cos \left(\dfrac{2 \pi}{5}x\right)+10=16, \quad \textsf{when}\; \left(\dfrac{2 \pi}{5}x\right)\; \textsf{is in radians}.[/tex]

Subtract 10 from both sides of the given equation:

[tex]\implies 12 \cos \left(\dfrac{2 \pi}{5}x\right)=6[/tex]

Divide both sides of the equation by 12:

[tex]\implies \cos \left(\dfrac{2 \pi}{5}x\right)=\dfrac{1}{2}[/tex]

Take the inverse of cosine of both sides:

[tex]\implies \dfrac{2 \pi}{5}x = \cos^{-1}\left(\dfrac{1}{2}\right)[/tex]

[tex]\implies \dfrac{2 \pi}{5}x =\dfrac{\pi}{3}+2 \pi n, \dfrac{5 \pi}{3}+2 \pi n[/tex]

Multiply both sides by 5:

[tex]\implies 2 \pi x=\dfrac{5 \pi}{3}+10 \pi n, \dfrac{25 \pi}{3}+10 \pi n[/tex]

Divide both sides by 2π:

[tex]\implies x=\dfrac{5 \pi}{6 \pi}+\dfrac{10 \pi}{2 \pi}n, \dfrac{25 \pi}{6 \pi}+\dfrac{10 \pi}{2 \pi}[/tex]

Simplify:

[tex]\implies x=\dfrac{5}{6}+5n, \dfrac{25}{6}+5n[/tex]

The two smallest possible solutions for x are when n = 0:

[tex]\implies x=\dfrac{5}{6}, \quad x=\dfrac{25}{6}[/tex]

Normal model for sizes is (7,1)

Here 5% of female customer have foot size in between 6-10

a)We were told that there are dress shoes in sizes 6 to 10 point, and the tailor believes that, with the exception of 5% of his female customers, the shoe would fit almost everyone. As a result, it accounts for 95 percent of female customers or women who try on his shoes, and we've been asked to determine what standard model for sizes is consistent.

b)The mean is 8 and the standard deviation is 2 points. So, we can say that x follows a normal model with a mean of 8 and a variance of 4 point right and in part b, we were asked whether a retailer should order more shoes in sizes 4 and 5 or more shoes in sizes 11 and 12 point so the best way to do this is to draw a balk curve or the symmetric table.

It follows from the task content that the angle theta described has; it's tan value to be negative and it's sine value to be positive.

Hence, since only sine of angles is positive in quadrant II while tan and cosine values are negative, it follows that the quadrant where theta is located is; Quadrant II.
