Given that a company budgeted 5 1/4 hours to complete a project, determine how much time they spent on research if they spent 1/3 of the total budget. 
First, convert the budget from hours into minutes. 
5 1/4 hours = 315 minutes 
1 hour = 60 min 
1/4 hour = 15 min 
60 x 5 = 300 
300 + 15 = 315 
Then, divide the minutes by 3 or multiply it by 1/3. 
315 / 3 = 105 
315 x 1/3 = 105 
Lastly convert to a mixed number. 
1 3/4 hour 
Thus, the company plans to spend 1 3/4 hours or 1 hour and 45 minutes on research.
 
        
             
        
        
        
Answer:
K=10 H=65
Step-by-step explanation:
To work out K, you need to know that opposite angles are the same, so 5k is the same as 50, 50÷5= 10, so k=10
To work out H, you know that opposite angles are the same so 2h is the same as 130, 130÷2=65 so h=65
 
        
             
        
        
        
4.75 = 4 75/100 =
 = 475/100 = ( we can divide numerator and denominator by 25 ) = 19/4
Answer:
4.75 as an improper fraction in simplest form is 19/4.
        
                    
             
        
        
        
150 x 5= 750
20 x 5= 100 ... so they should expect 100 cellphones to be defective
        
                    
             
        
        
        
Answer:
0.2 or 20%
Step-by-step explanation:
If the times of arrival vary uniformly, there is an equal chance of an employee reporting at any given time between 8:40 and 9:30.
The range between 8:40 and 9:30 is 50 minutes.
The range between 9:00 and 9:10 is 10 minutes.
Therefore, the  probability that a randomly chosen employee reports to work between 9:00 and 9:10 is:

The probability is 0.2 or 20%.
