If you simplify 12 over 6, you get 2 pounds for $1. And it is 50 cents for one pound, so you need to find it for 3 pounds. It would be $1.50
A reasonable estimate could be any number that makes sense. Say the average elementary student is 4' 10" then a reasonable estimate could be 3' to 3' 6" because the desk would be about a 1' 6" shorter than the person.
Answer: 20

Answer:
Step-by-step explanation:
First, draw the diagram.
We have the variable, l.
Then, we have:
tan angle=opposite/adjacent
So plug it in, it will be:
tan 60=l/50m
So then l=tan60*50m.
tan60=1.732
l=1.732*50m
and so out answer ends up being 86.6m.
Note: I don't know if this is the best way but...that's how I did it.
First, we know that all supplementary angles add to 180°. Then, since the angles are in the ratio 4:5, we can also represent these angles as 4x and 5x respectively. Both angle measures have the same variable (x) because no matter how large the angles are, they must have a common multiple because they are in a ratio. We can then write the formula 4x+5x=180 and solve for x. First, you combine like terms to get 9x=180. The you divide both sides by 9 to get x=20. Then, we can find both angles to be 80 (4*20) and 100 (5*20) by plugging them into 4x and 5x. Since 100 is larger, that is your answer.
I hope this helps.
