I think the answer is yes you can because they are both different things. 
What I mean by that is that the United Stated as .151% of its people with hearing problems, and .093% with vision problems. So really adding them together just mixes it saying that .244% of people in the united states have either a vision or a hearing problem.
It doesn’t make it any more or any less people by adding them together. Therefore it’s not any more or any less probable to pick one or the other.
Hopes this helps.
        
             
        
        
        
Answer:
45.05 seconds
Step-by-step explanation:
Use the formula: d = v
 t + 
 a
d = distance      v
 = initial velocity (m/s)    
t = time (s)     a = acceleration (m/
)
m is meters and s is seconds. They are units of measurement so leave them be. 
Assuming the object is simply dropped, the initial velocity is 0 since the object was not moving before it was dropped. 
The distance is 725 feet, which is 220.98 meters. 
The acceleration is 9.81m/
 since that is the acceleration of Earth's gravity, aka free fall. 
Time is what we are trying to find so just leave it as the variable t.
So plug the values into the equation:
220.98m = (0)(t) + 
 (9.81m/
)(t)
220.98m = (4.905m/
)(t)
45.0519877676s = t
t = 45.05s
Remember to pay attention to units because your answer will be wrong otherwise

Answer:
The pre-tax price of "smart fabric" warm-ups is $745 .
Step-by-step explanation:
Let us assume that the pre-tax price of the "smart fabric" warm-ups be x .
As given
arold paid 5% in sales tax on his new "smart fabric" warm-ups.  
if harnold paid 37.25 in sales tax on the warm ups .
5% is written in the decimal form .

= 0.05
Equations becomes 
0.05 × x = 37.25 
0.05x = 37.25 

x = $745
Therefore the pre-tax price of "smart fabric" warm-ups is $745 .
