Anew baby is born every .08 seconds. how many babies are born in two hours?

90,000

Step-by-step explanation:

Let's calculate how many seconds we have in two hours.

In one hour we have 60 minutes, so in 2 hours we have 2*60 = 120 minutes.

In one minute we have 60 seconds, so in 120 minutes we have 120*60 = 7,200 seconds.

Now we can use a direct rule of 3. If in 0.08 seconds 1 baby is born, how many babies will be born in 7,200 seconds?  

We use the formula of the direct rule of 3:

x = 90,000

90,000 babies are born in 2 hours.

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.
