Se sabe que 29 obreros pueden hacer una obra en 18 dias luego de haber realizado la mitad de la obra son cambiados por obreros 50% mas eficientes que ellos . si terminan la obra "a" dias antes de lo previsto calcule a+n

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

146

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

answer: the up tack or falsum is a constant symbol used to represent a logical constant denoting "false" in logic.
