<h2>Step-by-step explanation:</h2>

En este problema tenemos un tre que parte de una estación cualquiera. Sabemos lo siguiente:

Hora de salida: 18 horas 57 minutos exactos

Hora de llegada: 20:30 minutos 35 segundos

Bien, centrémonos en la hora de salida. Para las 19 horas solo faltarían 3 minutos, mientras que desde las 19 horas hasta las 20 con 30 minutos hay 1 hora y media. Adicionalmente, tenemos 35 segundos más. Por lo que tenemos:

  • 3 minutos
  • 1 hora y media
  • 35 segundos

De aquí podemos concluir que <em>el viaje duró 1 hora 33 minutos y 35 segundos.</em>

Hello!

If you divided by two then added 8 to reach 17, simply reverse the process, like so:

17 - 8 = 9

9 * 2 = 18

<u>Jordan's allowance is $18</u>

I hope this helps, and have a nice day!

<h2>The stone fall in air for 7 seconds and fall in water for 5 seconds.</h2>

Step-by-step explanation:

Total distance to sea bed = 127 m

Let the distance traveled in air be s.

Distance traveled in water = 127 - s

Average velocity in air = 16 m/s

Average velocity in water = 3 m/s

Distance traveled in air = Average velocity in air x Time in air

s = 16 x t₁

t_1=\frac{s}{16}

Distance traveled in water = Average velocity in water x Time in water

127-s = 3 x t₂

t_2=\frac{127-s}{3}

We have total time is 12 seconds

That is

                t₁ + t₂ = 12

                \frac{s}{16}+\frac{127-s}{3}=12\\\\3s+2032-16s=576\\\\13s=1456\\\\s=112m

We have

            s = 16 x t₁

            112 = 16 x t₁

             t₁ = 7 s

           t₁ + t₂ = 12

            7 + t₂ = 12    

             t₂ = 5 s

The stone fall in air for 7 seconds and fall in water for 5 seconds.

If h(x)=6-x, what is the value of (h•h) (10)?
butalik [34]

Answer:

16

Step-by-step explanation:

h(x) = 6 - x

h.h = (6 - x)²

h.h = x² - 12x + 36

h.h(10) = 10² - 12(10) + 36 = 16
