Answer: B
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.
Answer:
20
Step-by-step explanation:
We can use the Pythagorean theorem to solve
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
12^2+16^2 = c^2
144+256 = c^2
400 = c^2
Take the square root of each side
sqrt(400) = sqrt(c^2)
20 = c
