What is the total length of all the ski trails that are 2 7/8 miles long?

Answers

Answer:

[tex]Total\ length = 8\frac{5}{8}\ miles[/tex]

Step-by-step explanation:

Given

See attachment for ski trails

Required

Total length of [tex]2\frac{7}{8}[/tex] ski trails

From the attached figure, there are 3 skis with length [tex]2\frac{7}{8}\ miles[/tex]

So:

The total length is:

[tex]Total\ length = 3 * 2\frac{7}{8}[/tex]

Express fraction as improper fraction

[tex]Total\ length = 3 * \frac{23}{8}[/tex]

[tex]Total\ length = \frac{3 *23}{8}[/tex]

[tex]Total\ length = \frac{69}{8}[/tex]

[tex]Total\ length = 8\frac{5}{8}\ miles[/tex]

What does AD equal? PICTURE INCLUDED* Triangle congruence and similarity.

Answers

Answer:

AD = 7

Step-by-step explanation:

Given that the two triangles are similar by the SSS (side side side) postulate, the triangles share the same ratios when it comes to their sides.

We know the values for lines DB, EB and CB, therefore we can solve for AB, and subtract DB to find AD

We can solve the problem by solving for x:

[tex]\frac{x}{32} =\frac{21}{24}[/tex]

Cross multiply.

[tex]24x = 672[/tex]

Simplify.

[tex]x=28[/tex]

Subtract the value of DB to find AD.

La profundidad de una alberca aumenta paulatinamente desde 0.80 metros hasta 3 metros en una longitud de 10 metros cual es el angulo de inclinacion de la alberca

Answers

Answer:

El ángulo de inclinación de la alberca es aproximadamente 12.407º.

Step-by-step explanation:

Puesto que conocemos la distancia horizontal ([tex]l[/tex]) y la variación en la profundidad ([tex]h[/tex]) de la alberca, en metros, podemos emplear la siguiente razón trigonométrica para calcular el ángulo de inclinación de la alberca ([tex]\alpha[/tex]), en grados sexagesimales:

[tex]\alpha = \tan^{-1}\left(\frac{h}{l} \right)[/tex] (1)

Si sabemos que [tex]l = 10\,m[/tex] y [tex]h = 2.20\,m[/tex], entonces el ángulo de inclinación de la alberca es:

[tex]\alpha \approx 12.407^{\circ}[/tex]

El ángulo de inclinación de la alberca es aproximadamente 12.407º.

Answers

y = 1
x = 0
1 = 0(2)+k
K = 1
Answer is C) 1

Looking at the graph:
(x,y) = (-2,5)
y=x^2 + k
5=(-2)^2 + k
5=4+k
k=5-4
k=1
Again, looking at the graph:
(x,y)=(-3,10)

10=(-3)^2+k
10=9+k
k=10-9
