conjunto de números reales
naturales (n): el conjunto de los números naturales tiene como elementos al numero cero y a
todos los numeros que el hombre uti za para contar.
si representamos el conjunto de los números naturales simbólicamente y por extension
tenemos
n: 0.1.2.3.4.
enteros (z): el hombre para resolver los casos de imposibilidad de la sustracción en n. creo
los números enteros
z=,-3,-2.-1.0.1,2,3,
donde : z uz
nota:
el cero es negativo, puesto que no es positivamente ni negativo
con los 2, no hay restriccion es la sustraccion. ejemplos:
•
a) 7.4 = 3
b) 10-2 = 8
c) 5-5 = 0
d) 4-6 = 2
e) 2-9 = 7
a 1-3=2

entering that problem on the tube might get you an answer

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.

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

i believe your answer is a
