The answer is c because when you have 1 number and a variable(s) you just add the number to the variable(s)
        
                    
             
        
        
        
Step-by-step explanation:
Total marbles = 10 
No of white marbles = 4 
No of blue marbles = 6
Probability of 2 white marbles = 4/ 10 = 2/5

Answer:
40 feet
Step-by-step explanation:
Given : The deck is at a height of 520 ft. She sees her friend on the ground below at an angle of depression of 85.6 degrees. 
To Find : What is the distance between the two? Round your answer to the nearest tenth of a foot.
Solution : 
Refer the attached figure 
Height of deck =AB =520 ft.
Angle of depression ∠C = 85.6°
We are supposed to find length of BC i.e. distance between two.
We will use trigonometric ratios :





Thus the distance between two is 40 feet
