Answers

Answer:

120

Step-by-step explanation:

multipy 30 by 4 and you should get 120.

You can even do 30+30+30+30 and it will also add up to 120.

An observation tower is 75m high. A support wire is attached to the tower 20m the top. If the support wire and the ground form an angle of 46 degrees, what is the length of the support wire, to the nearest tenth?

Answers

Answer:

76.46m

Step-by-step explanation:

Using what we know we can solve for the length of the support wire using Pythagoras.

Height of tower = 75m

Support wire 20 m from top

Angle formed (α) = 46°

Using Pythagoras :

Sinα = opposite / hypotenus

Height used = height of tower - 20 m from top

Height = opposite = (75 - 20)m = 55m

Hypotenus = Length of support wire

Sin 46 = 55m / hypotenus

Hypotenus * sin 46 = 55

0.71934 * hypotenus = 55

Hypotenus = 55/0.71934

Hypotenus = 76.458976

Hence, Lenght of support wire = 76.46 m

Task 4—Solving Rational EquationsUsing the equation below as a model, fill in numbers in the place of a and b to create a rational equation that has an extraneous solution.

x + a (over(fraction)) ax = b (over(fraction)) x

Part 1. Show all work to solve for x in the equation and check the solution.

Part 2. Explain how to identify the extraneous solution and what it means.

Answers

Answer:

x = 7 is a solution

x = -2 is an extraneous solution.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Using the equation below as a model, fill in numbers in the place of a and b to create a rational equation that has an extraneous solution.

X + 4 / 4x = 8 / x

Part 1. Show all work to solve for x in the equation and check the solution.

X + 4 / 4x = 8 / x

x(x + 4) = (4x)8

x^2 + 4x = 32x

x^2 + 4x - 32x = 32x - 32x

x^2 - 28x = 0

x(x - 28) = 0

X = 0 or x = 28

Part 2. Explain how to identify the extraneous solution and what it means.

The solution x = 0 is extraneous because you are not allowed to divide by 0.

There are 30 homes in Neighborhood A. Each year, the number of homes increases by 20%. Just down the road, Neighborhood B has 45 homes. Each year, 3 new homes are built in Neighborhood B.Part A: Write functions to represent the number of homes in Neighborhood A and Neighborhood B throughout the years. (4 points)
Part B: How many homes does Neighborhood A have after 5 years? How many does Neighborhood B have after the same number of years? (2 points)
Part C: After approximately how many years is the number of homes in Neighborhood A and Neighborhood B the same? Justify your answer mathematically. (4 points)

Answers

Neighborhood A: 30 homes. Each year increases by 20%.
Neighborhood B: 45 homes. Each year increases by 3.

A: 30(1.20)^x
B: 45 + 3x

A: 30(1.20)^5 = 30(2.48832) = 74.6496 or 75 houses
B: 45 + 3(5) = 45 + 15 = 60 houses

Julián invito a sus amigos a comer una pizza. Él comió 2/8 del total. Juan comió el doble que Julián y mica comió la mitad de lo que comió juan. a- ¿Cuántas porciones tenía la pizza? b- ¿Cuántas comió Julián? c- ¿Cuántas comió juan? d- ¿y Mica? e- ¿Cuántas porciones sobraron? f- Demuestra con un gráfico tus respuestas.

Answers

Answer:

a) La pizza tenía 8 porciones.

b) Julián comió 2 porciones.

c) Juan comió 4 porciones.

d) Mica comió 2 porciones.

e) No sobraron porciones.

f) Véase la imagen adjunta para mayor detalle.

Step-by-step explanation:

Sean $x$ , $y$ , $z$ las razones de consumo de Julián, Mica y Juan, de acuerdo con una lectura cuidadosa del enunciado tenemos que:

$x+y+z=1$ (1)

(i)Julián comió 2/8 del total:

$x = (2)/(8)$ (2)

(ii)Juan comió el doble que Julián:

$z = 2\cdot x$ (3)

(iii)Mica comió la mitad de lo que comió Juan:

$y = (1)/(2)\cdot z$ (4)

Al aplicar (2) en (3), tenemos que Juan comió:

$z = (4)/(8)$

Y ahora se aplica el resultado anterior a (4):

$y = (1)/(2)\cdot (4)/(8)$

$y = (2)/(8)$

a) El total de porciones queda representado en el denominador de las fracciones calculadas. Por tanto, la pizza tenía 8 porciones.

b) El número de porciones consumido por cada persona está representada por el numerador de las fracciones calculadas. Por tanto, Julián comió 2 porciones.

c) Juan comió 4 porciones.

d) Mica comió 2 porciones.

e) No sobraron porciones en tanto que la suma de porciones consumidas de las tres personas es igual al valor del denominador.

f) A continuación, anexamos el gráfico correspondiente que sustenta todos los cálculos matemáticos hechos en puntos anteriores.
