The ratio of pens to
pencils that are used by
Dunkins middle School
Students s is 3: 2. If there is
a total Of 160 Middle School
Students, how many of
them use Pencils?

PLEASE HELP AND EXPLAIN UR ANSWER :))

64 pencils.

Step-by-step explanation:

Pens  to pencils = 3 : 2 so 3/5 use pens and 2/5 use pencils.

So number who use pencils = 2/5 * 160

=  2 * 32

= 64 pencils.

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.
