A farmer's conveyor belt carries bales of hay from the ground to the barn loft. The conveyor belt moves at 80 ft/min. How many seconds does it take for a bale of hay to go from the ground to the barn loft?

ok

recall also, distance= rate*time they give you the rate for the belt 80ft/min

6 is the beginning right

what do i do next

13.3?

is that correct?

.075?

i wrote those trig things wrong. sorry
anonymous

what do i do next?

the ramp length , hypotenuse is... sin(30) = 12 / h h = 12/sin(30)
anonymous
  • anonymous
6?
DanJS
  • DanJS
sin(angle)=opposite side / hypotenuse 12 / sin(30) = 24
anonymous
  • anonymous
4?
DanJS
  • DanJS
distance = rate*time 24 = 80*t t = 3/10 sorry bout that
anonymous
  • anonymous
so .3?

the hay is lifted 12 feet, so the hypotenuse of this triangle could not be 6. Use the given information to find the hypotenuse: angle and height. Please look carefully at the problem. The hay is lifted 12 feet. How could the hypotenuse possibly be only 4 or 6 feet? Use trig to find the length of the hypotenuse. And please show your work, so that others can give you meaningful feedback on what you have done.

i just dont understnad how to do this problem and my work is on a calculator where im just dividng

@pleasehelpme5 so .3? I see a distinct pattern of guessing on your part. This is NOT the way to larn math. Please start by asking questions to help you understand what this problem is all about.

3/10 min, 60 seconds per 1 min, so \[\frac{ 3/10~\min }{ 1 }*\frac{ 60~~\sec }{ 1 ~~\min }= (180/10) \sec = 18 ~\sec\]

ok that makes more sense
anonymous
  • anonymous
thank you for the help
DanJS

1- find the distance to travel to the top using the sin function 2 - use d = rate*time to get the time to travel that distance at the given rate 3 - correct units
anonymous
  • anonymous
ok thanks so 18 sec is the final answer?
anonymous
  • anonymous
can you help me with a few other problems
DanJS
  • DanJS
yeah i misstyped the thing first, had to correct it
anonymous
  • anonymous
ok thanks so much
mathmale
  • mathmale
If you have other problems to do, please post them separately in the Ask a question box. Please refer back to what DanJS has done and try to apply that knowledge before y ou ask for help.

  • anonymous
ok thanks
DanJS
  • DanJS
good with trig functions and rate of travel now, yah

  • DanJS
welcome
