Question of the day:
kogti [31]

Answer:

  12 days 16 hours 22 minutes 7.5 seconds

Step-by-step explanation:

You are interested in the proportion ...

  earth time / heaven time = (1000 years)/(1 day) = (x days)/(3 seconds)

Multiplying by 3 seconds, we find ...

  x days = (3 seconds)(1000 years)/(1 day)

If we convert 1000 years to days, then the formula will give us "x days" as a number of seconds.

1000 years is a long enough time period that all of the leap-year rules come into play. So, we will use the average number of days in a year as 365.2425. Then 1000 years is 365,242.5 days, and we get ...

  x days = (3 seconds)(354,242.5) = 1,095,727.5 seconds

There are 3600 seconds in 1 hour, so this is ...

  x days = (1095727.5 s)/(3600 s/h) = 304.36875 h

The fraction of an hour converts to 22 minutes 7.5 seconds. The 304 hours converts to 12 days 16 hours.

When Gabe starts blowing his horn, we have 12 days 16 hours 22 minutes 7.5 seconds left on Earth.

_____

The number of minutes and seconds will vary, depending on what you consider to be the number of days in a year.

Alex73 [517]

Answer:  3528.25

Step-by-step explanation:Make a sideview sketch

you should have 2 triangles, one right-angled containing the height and a scalene triangle with angles 24° , 153° (the supplement of 27°) and 3°

the side opposite the 3° angle is 1000

by let the side opposite the 24° be x, (also the hypotenuse of the right-angled triangle)

x/sin24 = 1000/sin3

x = 1000sin24/sin3

let the height of the mountain be h

sin 27 = h/x

h = x sin27 = (1000sin24/sin3)(sin27)

= 3528.25
