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.
V=-4 this should be the answer

Answer:
∠F = 42° to the nearest degree
Step-by-step explanation:
In this question, we are asked to calculate the value of the angle.
Kindly note that since one of the angles we are dealing with in the triangle is 90°, this means that the triangle is a right-angled triangle
Please check attachment for the diagrammatic representation of the triangle
From the diagram, we can identify that the EF is the hypotenuse and the length FG is the adjacent. Thus , the appropriate trigonometric identity to use is the cosine
mathematically;
Cosine of an angle = length of adjacent/length of hypotenuse
F = 42.07
∠F = 42° to the nearest degree
