The farmer walks by the pen with the chickens and pigs. He counts 18 heads and 50 feet. How many of each, chicken and pigs, are there?

Answers

Answer 1

Answer:

chickens = 11

pigs = 7

Step-by-step explanation:

this would be solved using simultaneous equation

let c = chicken .

p = pigs

A normal pig and chicken both have 1 head. thus :

c + p = 18 equation 1

A normal pig has 4 legs and a normal chicken has 2 legs. Thus

2c + 4p = 50  equation 2

multiply equation 1 by 2

2c + 2p = 36 equation 3

subtract equation 3 from 2

2p = 14

p = 7

substitute for p in equation 1

c + 7 = 18

c = 11

What are the missing coordinates of the vertices of this rectangle?

Answers

Answer:

A ( -d , e )

B ( - d , -e )

C ( d , - e )

Step-by-step explanation:

The centroid of the circle is on the origin.

This means that coordinates are an equal distance away from each other

Ex. Coordinate A and coordinate B are an equal distance away.

The only difference between the coordinates is the signs of the x and y values

This is determined by what quadrant the specific coordinate is in

Ex. Coordinate A is in Quadrant 2.

Coordinates in Quadrant 2 have a negative x value and a positive x value

Because Coordinate A and the given coordinates ( d , e )  have an equal distance between them all we have to do to find the missing coordinate is add a negative sign in front of the x value (d)

That being said, the coordinate of A is (-d,e).

This process is used to find the rest of the missing coordinates

for B

B lies in Quadrant 3

Quadrant 3 = ( -x , -y )

* add negative signs to the x and y value of the given coordinate *

B  = ( -d , - e)

For C

C lies in Quadrant 4

Quadrant 4 = ( x , - y )

* add a negative sign to the y value of the given coordinate *

C = ( d, -e)

Answer:

7a + b - 16c

Step-by-step explanation:

So we have

7a-3b+c-8c+4b-9c

When it comes to problem like these, you need to combine like terms.

There's only one 'a' number, so that one remains the same.

Next, we have -3b and 4b. (-3b+4b)= b

Finally, there's (c-8c-9c).

(-8c-9c)= -17c

Take that and add the positive 'c' to it.

(-17c+c)= -16c

Put it all together now to get:

7a + b - 16c

Answer:

Step-by-step explanation:

A car is purchased for $30,000. The value of the car depreciates annually so that it is $24,000 after 1 year, $19,200 after 2 years, and $15,360 after 3 years. Why can this situation be modeled using an exponential function?
The value of the car depreciates annually by 20%.
The value of the car depreciates annually by 80%.
The value of the car depreciates annually by $6,000.
The value of the car depreciates annually by $4,800.

Answers

Answer:

It annually drops by 20%

Step-by-step explanation:

30,000 multiplied by 20% is 6000. Subtract 6000 from 30,000 and you get 24,000. 24,000 multiplied by 20% is 4,800. Subtract 4,800 from 24,000 and you get 19,200. Etc.

Determina el perimetro de las figuras geometricas que forman la rayuela

Perimetro: L=50 cm

Expresión:

Sustitucion:

P=_______/
La figura es un cuadrado y cada lado mide 50 cm

Answers

Answer:

2000cm

Step-by-step explanation:

Rayuela es un juego jugado por niños que se compone de 10 cuadrados.

Se nos da a partir de la pregunta anterior, la longitud del lado de un cuadrado = 50 cm

La fórmula para el perímetro de un cuadrado es 4a

Donde a = longitud del lado

El perímetro de 1 cuadrado =

4 × 50 cm

= 200cm

El perímetro de los cuadrados totales en la rayuela.

1 cuadrado = 200 cm

10 cuadrados = x

Multiplicar cruzada

x = 10 × 200 cm

x = 2000 cm

Por lo tanto, el perímetro de las figuras geométricas de una rayuela = 2000cm.

If a toy truck is created in a 2:9 scale, and the wheel of the toy is 14cm wide, how wide is the actual wheel?

Answer:63 cm

Step-by-step explanation:

Given

The scale of creation is 2:9

The width of the toy wheel is 14 cm

Suppose x is the actual width of the truck

[tex]\therefore \dfrac{2}{9}=\dfrac{14}{x}\\\\\Rightarrow x=\dfrac{9}{2}\times 14=63\ cm[/tex]

Thus, the width of actual truck is 63 cm

3. How would you explain to someone who has not yet studied trigonometry the
difference between an identity and an equation?

Answers

Answer:

Solving an equation means finding the value or values for which the two expressions are equal. ... An identity is an equation which is always true, no matter what values are substituted.

What is the difference between trigonometric identity and equation?

A trig identity is an equation that is true for all values of x;

For example:

sin²x + cos²x will always equal 1 no matter what the value of x.

There are some equations considered to be identities that are in fact not true all the time.

tan(2x) = 2tanx/(1 - tan²x) is not true when x = π/2 (right side is undefined).

A conditional equation is one that is true for a subset of the real numbers, i.e. for certain values of x, but not all.

For example:

sin²x - 1 = 0 is only true for some values of x.

sin²x = 1

sinx = ±√(1) = ±1

sinx = 1 or sinx = -1

x = sin-11 or x = sin-1(-1)

x = π/2 + 2kπ, k any integer or x = 3π/2 + 2kπ, k any integer (this can be condensed, but left this way for emphasis).
