The corner store sells one of its magazines for $ 6.75 including tax. On one weekend the store collected $ 114.75nfrom the sale of this particular magazine. What expression can be used to find the number of magazines, n, sold by the store for that weekend?

6.75÷114.75=n
6.75÷n = 114.75
6.75n=114.75
6.75 + n= 114.75​

Answer:

this is D

Step-by-step explanation:

Answer:

C. 8

Step-by-step explanation:

BD is the altitude of the right triangle.

Apply the altitude theorem of a triangle to find BD. Based on the theorem, thus:

h = √(xy)

Where,

h = BD

x = 16

y = 4

Plug in the values

BD = √(16*4)

BD = √64

BD = 8

Answer:

m >-7 or m < -10

Step-by-step explanation:

5+m >-2

subtract 5 from both sides

⇒5-5+m > -2-5

⇒m > -7

or..

2m <-20

divide both sides by 2

2m÷2 < -2÷2

⇒m= < -10

Resolviendo un sistema de ecuaciones veremos que polo hizo 170 polos.

Sabemos que por cada 12 polos que confecciona Ana, Beto hace 7.

Por cada 28 polos que confecciona Beto, Carla confecciona 15.

Y sabemos que Ana hizo 198 polos mas que Carla.

Definamos las variables:

C = polos que hizo Carla.

A = polos que hizo Ana

B = polos que hizo Beto.

Podemos escribir las ecuaciones:

A = C + 198

B = (7/19)*A

B = 28/(28 + 15)*C

Tenemos un sistema de ecuaciones, las segundas dos son las que obtenemos con los ratios que nos proporcionan.

Reemplazando la primer ecuacion en la segunda obtenemos el sistema:

B = (7/19)*(C + 198)

B = 28/(43)*C

De la segunda ecuacion podemos obtener:

C = B*(43/28)

Remplazando eso en la otra ecuacion obtenemos:

B = (7/19)*(B*(43/28)+ 198)

Ahora podemos encontrar el valor de B.

B = 0.57*B + 72.95

B - 0.57*B =  72.95

B*0.43 = 72.95

B = 72.95/0.43 = 169.6

Redondenado, B = 170, ese es el número de polos que Beto confecciono.

Answer:

33

Step-by-step explanation:

angles on a straight line sum up to 180°

104+x+x+10=180

114+2x=180

2x=180-114

2x=66

x=33

Answer:

C. 33

Step-by-step explanation:

So we have 180 degree line here, so lets take 104 and add the 10 from the expression inside the parenthesis on the other angle. We add 43 to 114 and get 147. We can then add 147+33 and get 180 which is equivalent to the angle.

Ecology is the study of relationships of living organisms and their environment

Step-by-step explanation:

Ecology in a simple sense is the the study of ecosystems

If the coordinate is (3, -2) then after the 90° counter-clockwise about the origin. Then new coordinate will be (2, 3).

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Convert the cartesian coordinate to the polar coordinate. Then we have

[tex]r = \sqrt{3^2 + (-2)^2}\\\\r = \sqrt{9 + 4 }\\\\r = 3.61\\\\\theta = \tan ^{-1}\dfrac{-2}{3}\\\\\theta = -33.69^o\\\\\theta = 326.31^o[/tex]

Then 90° counter-clockwise about the origin, then the angle will be

θ = 326.31 + 90 = 431.31

But θ is from 0 to 360. Then

θ = 431.31 - 360 = 56.31

Then convert the polar coordinate to the cartesian coordinate. Then we have

x = r cosθ

x = 3.61 × cos 56.31

x = 2

and

y = r sinθ

y = 3.61 × sin 56.31

y = 3

Step-by-step explanation:

Answer:

a

Step-by-step explanation:

the horizontal distance is shorter so the angle will be greater.

added:

tan a = AD/2a

tan Q - AD/3a

Just looking at the fractions AD/2a and AD/3a, the denominator of AD/2a is smaller so the resulting calculation will be greater, hence a is the larger angle.
