What problem can be solved by dividing 9/10 by 1/4

  (9/10)/(1/4) could be such a problem

Step-by-step explanation:

Here's another:

  If I walk 9/10 of a mile in 1/4 of an hour, what is my speed in miles per hour?

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.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
