Some people advise that in very cold weather , you should keep the gas tank in your car more than half full. Irene's car had 5.80 gallons in the 13- gallon tank on the coldest day of the year. Irene filled the tank with gas that cost 3.80 per gallon. How much did Irene spend on gas?

22.04

Step-by-step explanation:

We are told in the question that:

Irene filled the tank with gas that cost 3.80 per gallon.

She has 5.80 gallons in her tank.

Hence:

1 gallon of gas = 3.80

5.80 gallons =

Cross Multiply

5.80gallons × 3.80/1 gallon

= 22.04

Therefore, Irene spent 22.04 on gas

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.
