Nina makes 11.25 per hour.
Step-by-step explanation:
Given,
Number of hours worked by Nina = 32 hours
Amount earned by Nina = 360
Let,
x represent the amount earned by Nina per hour.
Amount per hour * Number of hours = Amount earned
Dividing both sides by 32
Nina makes 11.25 per hour.

A box sits on a table. A short arrow labeled F subscript N = 100 N points up. A short arrow labeled F subscript g = 100 N points down. A long arrow labeled F subscript P = 75 N points right. A short arrow labeled F subscript f = 10 N points left. Then net force acting on the box IS 65N
<h3>What is net force?</h3>
Net force is final force acting on any object .
Here given that
A box sits on a table. A short arrow labeled F subscript N = 100 N points up. A short arrow labeled F subscript g = 100 N points down. A long arrow labeled F subscript P = 75 N points right. A short arrow labeled F subscript f = 10 N points left
So we can see it in diagram that force in upper direction and lower direction is same 100N so this force will be cancelled out
Now force in right side is 75N and in left side force is 10N
So net force = (75-10)=65N in right side

Answer:
Proved
Step-by-step explanation:
2 sin square( 45°-A)
(therefore;
by trigonometry ratios
sin45°=1)
=2sin2(1-A)
=2sin(1-A)
=1+sin2A
hence proved
