Being home schooled I teach my self and I'm soon to graduate I can't seem to figure out these problem and I need to finish my math before Christmas :/ please help! Thanks!!
1. In question 2 you found that to beat at a rate of 200 beats per minute, a dragonfly's wing must be .36 inches. Using this data, find the constant for the inverse variation relating the length of an insects wing to the beats per minute.
2. Using the constant you found in problem 1, state whether a dragonfly with a wingspan of 1.2 inches will be able to stay aloft if his wings beat 50 times per second. Using complete sentences, explain your answers. Show all work.
3. Find the ratio of 28 days to 4 weeks.
4. Use a proportion to solve this problem: A map has a scale of 1 inch=50 miles. The distance between Chicago and Scranton is 750 miles. What is the distance on the map between Chicago and Scranton?

If the relationship is inverse then
B = k/L
B = beats
k = constant of variation
L = Wing length.
200 = k / 0.36
k = 200 * 0.36 = 72 beats / inch

I'll give you the math. You do the English. You have access to question 2.
B = k / L
B = 72 / 1.2
B = 60 beats/ minute.
B = 5 beats / second
3]
28 days / (4 weeks) = 28 days / 4*7 = 1: 1
4]
1 inch / 50 miles = x inches / 750 miles
50 x = 750
x = 15 inches between paper scranton and paper chicago
B = k/L

200 = k / 0.36
