Step-by-step explanation:
A = bxh
=(8)(5)
=40
Answer: b=5
Step-by-step explanation:
Multiply all terms by b and cancel:
3b/5+2=1b
3/5b+2=b(Simplify both sides of the equation)
3/5b+2−b=b−b(Subtract b from both sides)
−2/5b+2=0
−2/5b+2−2=0−2(Subtract 2 from both sides)
−2/5b=−2
(5−2)*(−25b)=(5−2)*(−2)(Multiply both sides by 5/(-2))
b=5
Check answers. (Plug them in to make sure they work.)
b=5 (Works in the original equation)
Answer:
b=5

Answer:
here you have to use the law of sines
let tree make an angle of 83 deg.with the ground. (YZ)angle ZYX = 83deg
he walks 100 feet away from tree to point X (YX)angle YXZ= 33 deg
so remaining angle YZX = 64 deg
triangle YXZ is formed
sin A /a = sin B /b = sin C /c
Sin YZX/100 = sin YXZ/ YZ
sin 64/100 = sin 33/YZ
100 * sin 33/sin 64 = YZ
100*0.54/0.898= YZ
YZ= 60.13 feet the height of the tree

Answer:
It will take the worm 7 days to get to the top of the well.
Step-by-step explanation:
the well is 37 feet deep
the worm climbs up 7 feet, but loses 2 feet through the night
That means the worm only really climbs 5 feet a day.
So, if you subtract 5 from 37, 6 times, you'll get 7 feet left to go. And sense the worm climbs 7 feet a day, the last day the worm will climb his way to the top without slipping back down.
Hopefully this makes sense.
It is rational................
