Liz had attended class everyday since she started school as a kindergartner. she said she had been in school for about 1,000 days. what numbers could be the actual number of school days if liz rounded to the nearest ten ?

Liz attended the school for 710 days.

Step-by-step explanation:

Let us suppose there are 365 days each year.

So, 1000 days become = years

And each year has 52 weeks out of which 5 days per week is a working day. There are working days

Let us suppose there are no holidays so, the number of days Liz attended school = rounding to nearest ten as 710.

Therefore, Liz attended the school for 710 days.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
