A car travels 450 miles on 20 gallons of gas. At that rate, how far will it travel on 30
gallons of gas?

675 miles

Step-by-step explanation:

450 : 2 = 225

10 gallons of gas = 225 miles

225 * 3 = 675

30 miles will get you 675 miles

c

step-by-step explanation:

at least i think its

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.
