Answer:

El alemán debe recorrer de la ciudad B a la ciudad A para llevar los cilindros de gas de cloro.

Step-by-step explanation:

De acuerdo con este problema, tenemos un ángulo y dos lados adyacentes, por tanto, podemos determinar la distancia entre las ciudades A y B, medida en kilómetros, por la Ley del Coseno, definida como sigue:

AB = \sqrt{AC^{2}+BC^{2}-2\cdot AC\cdot BC\cdot \cos C} (1)

Donde:

AC - Distancia entre las ciudades A y C, medida en kilómetros.

BC - Distancia entre las ciudades B y C, medida en kilómetros.

C - Ángulo en la ciudad C, medida en grados sexagesimales.

Si tenemos que AC = 5\,km, BC = 8\,km y C = 36^{\circ}, entonces:

AB = \sqrt{(5\,km)^{2}+(8\,km)^{2}-2\cdot (5\,km)\cdot (8\,km)\cdot \cos 36^{\circ}}

AB \approx 4,927\,km

El alemán debe recorrer de la ciudad B a la ciudad A para llevar los cilindros de gas de cloro.

Answer:
Ethan = 1.(3x)

Step-by-step explanation:
Let's split "Ethan saved 1/3 more than that"
That = x
So, Ethan saved 1/3 more than x
Meaning that Ethan = x + 1/3x
Combine like terms
Ethan = 1 1/3x
which equals to
Ethan = 1.(3x)

Hope this helps :)
Have a great day

Universal Pet house sells vinyl doghouse and treated lumber doghouses. It takes the company 5 hours to build a vinyl doghouses a
LuckyWell [14K]

Answer:

The system of equations is :

Equation 1- 5x+2y=50

Equation 2- x+2y=30

Number of vinyl doghouse = 5

Number of treated lumber doghouse =12.5

Step-by-step explanation:

Let x be the number of vinyl doghouses

y be the number of treated lumber doghouses

→If it takes the company 5 hours to build a vinyl doghouses and 2 hours to build a treated lumber doghouse. The company dedicates 50 hours every week towards assembling and painting doghouses.

Equation 1- 5x+2y=50

→It takes an additional hour to paint each vinyl doghouse and an additional 2 hours to assemble each treated lumber doghouse. The company dedicates 30 hours every week towards assembling and paining dog houses.

Equation 2- x+2y=30

→When we solve these equation we get the number of  vinyl doghouse and treated lumber doghouse.

Subtract equation 2 from equation 1

5x+2y-x-2y=50-30

4x=20

x=\frac{20}{4}

x=5

Put value of x in equation 2

x+2y=30

5+2y=30

2y=25

y=\frac{25}{2}

y=12.5

Therefore, number of vinyl doghouse = 5, number of treated lumber doghouse =12.5

Use an appropriate half-angle formula to find the exact value of the expression. cos(22. 5°)
Sladkaya [172]

The value of given trigonometric value cos(22. 5°) is 0.387.

According to the statement

we have given that the trigonometric value and we have to find the exact value of that given value with the help of the half angle formula.

So, For this purpose, we know that the

The half angle formulas are used to find the exact values of the trigonometric ratios of the angles like 22.5°.

So,

The given value is :

cos(22. 5°)

Then the value of cos half angle formula is

cos (theta/2) = +- sqrt((1-cos theta) / 2)

then

The value of θ/2 is 22.5 degree.

And θ is 22.5*2

θ = 45 degree

and cos 45 degree is 1/squareroot 2

And by this the value of given value become is

cos 22.5 =  +\sqrt{((\sqrt{2}  -1)/(2 \sqrt{2} )) }  = + 0.3827

So, The value of given trigonometric value cos(22. 5°) is 0.387.
