Ответ:

250

Пошаговое объяснение:

за первые 2 дня скосили 34+36=70%, значит за третий 100-70=30%, значит 1% это 75га / 30% = 2.5 га, значит 100% это 2.5 × 100 = 250 га.

Переведите грамотно пожалуйста) It
was July 16, 2008 and I was at
City Hall to do something that would change
my life forever. I went to Room 302 and got my working card. I
thought I was independent and ready
to get a job. First I filled in applications. I put in over
100 applications at restau-rants, clothing stores, and hotels. I kept looking
for a job, and I decided to go to the mall. I
was interested in getting a place in
one restaurant because my good school friend worked there, and he
told me they needed people. I thought it might
turn out to be successful. One day,
when I came home and turned on
the answering machine, there was a message on it. It was a
job! A lady from a supermarket called me for an interview
on Tuesday. I was very excited. This
was my first interview. On Sunday I
got up early, my mom and I went
shopping fore dress. I put on this dress on Tuesday. The lady asked
me a lot of questions, but I thought over the
answers the day before. I didn’t get
the job, but I found out that
you can’t get a job easily. It’s very
hard work.
