There are 1,200 refrigerators numbered 1 to 1,200. Suppose you open all of the refrigerators and then close every other refrigerator. Then, for every third refrigerator, you close each opened refrigerator and open each closed refrigerator. You follow the same pattern for every fourth refrigerator, every fifth refrigerator, and so on up to every twelve hundredth refrigerator. Which refrigerators will be open when the process is complete? Describe the mathematics that is underlying this math problem in your answer.

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

step-by-step explanation:

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
