 <span>Draw a regular hexagon. Connect the center to each of the six vertices. Thus, you have six triangles, each with base 10.. The apothem is the height of each triangle. Then the area of each triangle is (1/2)(10)(12) = 60. You have six triangles so the aarea of the hexagon is 6*60 = 360.</span>

En un día de temporal de lluvia el meteorólogo dijo en las noticias que la probabilidad de que lloviera ese día era del 70%. ¿Qu
drek231 [11]

Answer:

Vamos a definir:

100% probabilidad de lluvia = Es seguro que ese día va a llover.

0% probabilidad de lluvia = Es seguro que ese día no va a llover.

Ahora, los valores intermedios admiten una dualidad, es decir, es posible que llueva o que no.

Particularmente en el caso del 70% significa que:

Si tenemos un dado de 10 caras, con los números {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Y lo tiráramos, los resultados {1, 2, 3, 4, 5, 6, 7} indicarían que llueve.

Los resultados {8, 9, 10} indicarían que no llueve.

Entonces es mas probable que llueva, pero la probabilidad de que no llueva no es despreciable.

Write a quadratic function to model the vertical motion for each​ situation, given ​h(t) equals negative 16t squared plus v0t+h0
Mashcka [7]

Answer:

hmax = 194 ft

The maximum height is 194 ft

Step-by-step explanation:

According to the given equation for the model of the vertical motion. The height at any point in time can be written as;

h(t) = -16t^2 + v0t + h0 .......1

Where;

h(t) = height at time t

t = time

v0 = initial velocity = 96 ft/s

h0 = initial height = 50 ft

To determine the maximum height we need to differentiate the equation 1 to find the time at which it reaches maximum height;

At the highest point/height h' = dh/dt = 0

h'(t) = -32t +v0 = 0

-32t + v0 = 0

t = v0/32

t = 96/32

t = 3 s

At t=3 it is at maximum height.

The maximum height can be derived from equation 1;

Substituting the values of t,v0,h0 into equation 1;

h(t) = -16t^2 + v0t + h0 .......1

hmax = -16(3)^2 + 96(3) + 50 = 194 ft

hmax = 194 ft

The maximum height is 194 ft

Keelahs clothing store buys coats for $50 and then sells them for $80 what is the percent of mark up on the price of the coat sh
olchik [2.2K]
I don't know if you meant profit or markup but, 

take the difference of $80 & $50 = $30

What percent of 50 is 30? It's 3/5 or 60%. So there is a 60% markup on the original price of 50$.
