Jeff has already prepared 6 kilograms of dough and will continue preparing 1 kilogram of
dough every hour. how much dough did jeff prepare if he worked for 11 hours?

ANSWER:  

Dough prepared by Jeff after working for 11 hours is 17 kg

SOLUTION:

Given that, Jeff has already prepared 6 kg of dough.  

And, he will continue preparing at the rate of 1 kg of dough per an hour.

Rate of preparation = = 1 kg per hour.

If Jeff worked for 11 hours, then dough prepared = rate of preparation time taken

Dough prepared =

Dough prepared = 11 kg

Total dough prepared by Jeff = already prepared 6kg of dough + dough prepared in 11 hours  

Total dough = 6 + 11 = 17kg

Hence, dough prepared by Jeff after working for 11 hours is 17 kg

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.
