Answer:
540°.
Step-by-step explanation:
On a unit circle, cos θ = -1 at 180°.
However, cos θ has a period of 2π, or 360°. This means that cos θ will equal to -1 again after 2π.
To solve for the angle:
180° + 360° = 540°. This is the next angle at which cos θ = -1.
 
        
                    
             
        
        
        
we are going to create a table in excel and
we will assign different values of topping to know when the price is equal in
both pizzerias
 
see the attached figure
 
the answer is
5 toppings from palanzio’s pizzeria
6 toppings from guido’s
pizza
cost palanzio’s pizzeria----> 6.80+0.90*5-----> $11.30
cost <span>guido’s pizza------> 7.40+0.65*6----------> $11.30</span>
 
 
        
             
        
        
        
First of all, let's convert all the measures to the same unit: 4 feet are 48 inches.
Now, as the wheel turns, there is a proportion between the angle and the distance travelled: for example, when the car moves forward a whole circumference, the angle will be 360°. Conversely, if the wheel turns 180°, then the car will move forward a distance which is half the circumference of the wheel, and so on.
Since the radius is 16 inches, the circumference will be

So, we have the following proportion:

that you can read as: "if an angle of 360 corresponds to a distance travelled of  , then the unknown angle x corresponds to a distance travelled of 48 inches.
, then the unknown angle x corresponds to a distance travelled of 48 inches.
Solving for x, we have
