Answer:
$3.4875
Step-by-step explanation:
AS the ride is completed and according the rule the person have to give a tip on the total taxi ride
according to the given
tip given 15%
Total ride cost = $23.25
To find is the total tip given in dollars
Solution:
Total tip in dollars = 15 % of total ride cost
 Putting the values of the given
Total tip in dollars = 15 % of 23.25
 it can be written as
                              = 
                               =
                                =$ 3.4875
So the total tip would be $3.4875
 
        
             
        
        
        
Answer:
Maximum height of quarter tower = 9.6 inches.
Step-by-step explanation:
The thickness of a quarter =  inches
 inches
Weight of a quarter = 1 ounce
The maximum weight that could safely hold = 3 pounds.
<u>The conversion factor for ounce to pound is 1 ounce = 0.0625 pound</u>
The number of quarter used in the tower = no of ounces equivalent to 3 pounds.
No of ounces equivalent to 3 pounds = 
No of ounces equivalent to 3 pounds = 48
So the height of quarter tower = 48 \times  inches
 inches
                                                    = 9.6 inches.

A stuntman jumping off a 20-m-high building is modeled by the equation h = 20 – 5t2, where t is the time in seconds. A high-speed camera is ready to film him between 15 m and 10 m above the ground. For which interval of time should the camera film him?
Answer:

Step-by-step explanation:
Given:
A stuntman jumping off a 20-m-high building is modeled by the equation
 -----------(1)
-----------(1)
A high-speed camera is ready to making film between 15 m and 10 m above the ground
when the stuntman is 15m above the ground.
height  
  
Put height value in equation 1





We know that the time is always positive, therefore 
 
when the stuntman is 10m above the ground.
height  
  
Put height value in equation 1







Therefore ,time interval of camera film him is
