a) 121,000
b)8.35 x 10^-6
Step-by-step explanation:
Answer:
Unit rate of people per book = 2.5
Step by step explanation:
Given:
Number of peoples = 
Number of books = 
Their ratios = 
We have to find the unit rate of people per book.
To find out the unit rate of people per book we have to divide the total number of peoples by the total number of books.
Or
For this we will follow the unitary method:
For
book there are
persons.
For
book there will be
persons.
So,
The numeric value =
=
There are 2.5 people per book and that it also the unit rate of people per book.
22 degrees; you can subtract 180-158 to get the measure of U and U is equal to S because of parallel lines
Rounding to the nearest ten:
28 → 30
188 → 190
250 → 250
101 → 100
122 → 120
