How much work is done in an hour by each:
s = 1/6 of the yard in one hourb = 1/10 of the yard in an hour
working together they can do:
1/6 + 1/10 in an hour; or 16/60; we can invert this number to determine how long it takes to finish the yard
60/16 hours
=3 hours and 45 minutes
If the hotel pays the carpet cleaners $40 per room and they have a max price of 200 ur equation should be

4h+3p=13.75
2h+5p=11.25
4h+10p=22.50
4h+3p=13.75
7p=8.75
one pretzel =1.25
2h+5(1.25)=11.25
2h+6.25=11.25
2h=5

Answer:
149.43 feet tall
Step-by-step explanation:
From the base of a large tree, a bird watcher is standing 50 feet away.
There is 71.5° of elevation from the bird watcher to a bird on the top of the tree.
If we ignore the height of the observer and consider the height of the tree as h feet, then using trigonometry we can write that
tan 71.5° = 
= 
Hence, h = 50 tan 71.5° =149.43 feet.
Therefore, the tree is 149.43 feet tall. (Answer)
