Juanita spent 3/4 of her allowance at the mall. of the money spent at the mall, 1/2 was spent on new earphones. what part of her allowance did juanita spend on earphones?

Let

x--------> Juanita's allowance

we know that

1) Juanita spent of her allowance at the mall

so

Juanita spent at the mall -------->

2) Of the money spent at the mall, was spent on new earphones

so

Juanita spent on new earphones ------->

therefore

the answer is

Juanita spend on earphones of her allowance

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
