Across the horizon i think... i hope i helped
If the puzzle was solved in 1/5 hour, we can multiply the time it took to solve one puzzle by 5.
2/5(5/1)
=10/5
=2
So she'll be able to solve 2 puzzles in one hour.

B is incorrect which means it is the answer
Answer:
You set up an equation, using the trig function "tan" to find half of the roof (the equation would be tan(24) = 3.5/x, where x = 1/2 roof width)
Step-by-step explanation:
That would be the first step.
You solve the equation for x, and then multiply x by 2 to get the width of the roof.
For a, each time it is taking away 2 places. 3,400,000, taking away 2 zeros is 34,000. Like they have in the example. So you need to take away 2 places for the first blank. For the second blank you need to move the decimal place 2 places to the left. For b, it's taking away 1 place, so do the same thing but with one place. For the first blank, add a place.
