You have a set of calipers that can measure thicknesses of a few inches with an uncertainty of 0:005 inches. I mesure the thickness of a deck of 52 cards and get 0.590 in: (a) If you now calculate the thickness of 1 card, what is my answer, including its uncertainty? (b) I can imporve this result by measuring several decks together. If I want to know the thickness of 1 card with an uncertainty of only 0.00002 in., how many decks do I need to measure together?

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

c.the first excerpt shows their expectations about the camp, and the second shows the reality of their circumstances

is the answer this is because first they talk about what is expected of the camp but in the second excerpt they get a harsh awakening to the true realities of the camp.

hope this

i would appreciate brainliest : )
