The expression sin 57° is equal to

(1) tan 33°

(3) tan 57°

(2) cos 33°

(4) cos 57°

Answers

Answer 1

Answer:

[tex]cos(33^{\circ})[/tex]

Step-by-step explanation:

Given

[tex]sin(57^{\circ})[/tex]

Required

Determine an equivalent expression

In trigonometry:

[tex]sin(\theta)= cos(90^{\circ} - \theta)[/tex]

In [tex]sin(57^{\circ})[/tex]

[tex]\theta=57^{\circ}[/tex]

Substitute [tex]57^{\circ}[/tex] for [tex]\theta[/tex]

in [tex]sin(\theta)= cos(90^{\circ} - \theta)[/tex]

[tex]sin(57^{\circ})= cos(90^{\circ} - 57^{\circ})[/tex]

[tex]sin(57^{\circ})= cos(33^{\circ})[/tex]

Hence, the equivalent expression is: [tex]cos(33^{\circ})[/tex]

Se necesitan cortar 3 cintas de 40 cm, 50 cm y 60 cm, en trozos igua-
les de manera que todas sean iguales y con la mayor longitud posible.
¿Cuántos trozos se cortarán?​

Answers

Answer:

Se cortarán en 15 trozos.

Step-by-step explanation:

Para determinar la longitud de cada trozo tal que todos los trozos tengan la misma longitud, se descompone factorialmente cada número:

[tex]40 = 2\times 2 \times 2 \times 5[/tex]

[tex]50 = 2\times 5\times 5[/tex]

[tex]60 = 2\times 2\times 3\times 5[/tex]

Ahora, determinamos el factor común de los tres números. Se puede encontrar que los tres números comparten un 2 y un 5. Entonces, el factor común es:

[tex]r = 2\times 5 = 10[/tex]

Este factor común representa la longitud de cada segmento. La cantidad de elementos se obtiene al dividir la suma de longitudes de las cintas por el factor común:

[tex]x = \frac{40\,cm+50\,cm+60\,cm}{10\,cm}[/tex]

[tex]x = \frac{150\,cm}{10\,cm}[/tex]

[tex]x = 15[/tex]

Se cortarán en 15 trozos.

find the value of X in the equation below 8x=2.4 (plz be fr)

Answers

Answer:

x=0.3

Step-by-step explanation:

divide 8 by both sides to isolate x

8x/8= 2.4/8

2.4/8= 0.3, leaving x by itself, giving us x=0.3

Hope this helps and have a great week!

answer:x = 0.3

Step-by-step explanation:Simplifying

8x = 2.4

Solving

8x = 2.4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '8'.

x = 0.3

Answer:

Step-by-step explanation:

The graph of x - y = 1 is plotted below

Plotting linear graphs

The given equation is:

x - y = 1

The equation can be rewritten as:

y = x - 1

This is of the form y = mx + 1

where m is the slope

c is the y-intercept

Compare the equation y = mx + 1 with y = x - 1

The slope, m = 1

The y-intercept, c = -1

The graph of the equation y = x - 1 is plotted below

Answers

Answer:

[tex]?=240[/tex]

Step-by-step explanation:

We can let the [tex]?[/tex] be [tex]x[/tex]. Rewriting the proportion, we get:

[tex]\frac{50}{2000}=\frac{6}{x}[/tex]

Solving for [tex]x[/tex], we get:

[tex]\frac{50}{2000}=\frac{6}{x}[/tex]

[tex]50*x=2000*6[/tex] (Cross-Products Property)

[tex]50x=12000[/tex] (Simplify)

[tex]\frac{50x}{50}=\frac{12000}{50}[/tex] (Divide both sides of the equation by [tex]50[/tex] to get rid of [tex]x[/tex]'s coefficient)

[tex]x=240[/tex] (Simplify)

Since [tex]?=x[/tex], we know that [tex]?=240[/tex]. Hope this helps!

Answers

Answer:

$9 and $12

Step-by-step explanation:

Let "s" be small boxes and "L" be large boxes.

12*s + 6*L = $180

3*s + 2*L = $51

From the first equation:

L = ($180 - 12*s) / 6 = $30 - 2*s

Plug that into 2nd equation:

3*s + 2*($30 - 2*s) = 3*s + $60 - 4*s = $51

s = $9

L = $30 - 2*s = $30 - $18

L = $12

how do i graph x+4y=8​

Answers

Answer:

x = 8  y = 2

(8,2)

Step-by-step explanation:

You have to find the value of both x and y

x + 4y = 8

to find x you have to cancel out y so,

x + 4(0) = 8

x = 8

to find y you have to cancel out x

0 + 4y = 8

4y = 8

divide both sides by 4

y = 2

Hope this Helps!!!

By changing the equation to slope intercept form we draw the graph and graph is given in attachment.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Let us convert the equation of line  x+4y=8​ to slope intercept form.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

x+4y=8

4y=8-x

Divide both sides by 4

y=-x+2

Now let us find few point to draw the graph.

If x=0

y=2

If x=1

y=1

If x=2

then y=0

if x=3

then y=-1

Now plot (0, 2), (1, 1) and (3, -1) and draw the graph

Hence, by plotting the points (0, 2), (1, 1) and (3, -1) we draw the graph and the graph is in attachment.
