el 18% de los arboles del jardin de la plaza mayor son almendros y el resto son naranjos. si en la plaza 45 almendros, ¿ cuantos

andre [41]

Queremos resolver un problema sobre porcentajes, donde conociendo el porcentaje que un dado número representa, queremos encontrar el número equivalente al 100%.

Veremos que el número total de arboles es 250.

------------------------------------

Sabemos que el 18% de los arboles son almendros y el resto son naranjos, es decir, el porcentaje de naranjos es 100% - 18% = 82%

Y sabemos que hay 45 almendros.

Entonces el 18% del número total de arboles es 45.

Es decir, si hay N arboles en total, el 18% de N es igual a 45, esto se puede escribir como:

(18%/100%)*N = 45

0.18*N = 45

N = 45/0.18 = 250

Así podemos concluir que hay un total de 250 arboles en la plaza.

PLSS help me with this question?

Xelga [282]

Answer:

Part a) By alternate interior angles

Part b) By vertical angles

Part c) By AAA (Angle-Angle-Angle) Similarity Theorem

Part d) Triangles ABC and CDE are similar

Part e) $b=\frac{2DE}{3}$ or $b=\frac{15}{AC}$

Step-by-step explanation:

Part a)

we know that

If AB is parallel to DE

then

m<1=m<4 ------> by alternate interior angles

Part b)

we know that

m<5=m<6 -------> by vertical angles

Part c) we know that

The two triangles are similar by AAA (Angle-Angle-Angle) Similarity Theorem ------> The three corresponding angles are equal

m<1=m<4

m<5=m<6

m<3=m<2

Part d) we know that

If two figures are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

therefore

Triangles ABC and CDE are similar

Part e) Find the length side of b

Remember that

If two figures are similar, then the ratio of its corresponding sides is equal

$\frac{AB}{DE}=\frac{BC}{DC}=\frac{AC}{CE}$

substitute the values

$\frac{3}{DE}=\frac{2}{b}=\frac{AC}{7.5}$

$b=\frac{2DE}{3}$

$b=\frac{2*7.5}{AC}=\frac{15}{AC}$
