Answer:
<u>5 127/200 meters</u>
Step-by-step explanation:
4 1/2 = 4 5/10 | 4/5 = 8/10
--------------------------------------
4 5/10 = 4.5 | 8/10 = 0.8
--------------------------------------
4.8 divided by 0.8 = 5.625
--------------------------------------
5.635 = 5 635/1000
635/1000 divided by 5 = 127/200
--------------------------------------
5 + 127/200 = <u>5 127/200</u>
 
        
             
        
        
        
Y=145
Explanation:
A triangle’s angles add up to a total of 180 so you would subtract 55 from 180 and then subtract 90 because of the right angle, then you would end with x=35. Since x and y are supplementary they add to 180...so then you subtract 35 from 180 and then you get y=145.
        
             
        
        
        
Answer:
225.78 grams
Step-by-step explanation:
To solve this question, we would be using the formula
P(t) = Po × 2^t/n
Where P(t) = Remaining amount after r hours
Po = Initial amount
t = Time 
In the question,
Where P(t) = Remaining amount after r hours = unknown
Po = Initial amount = 537
t = Time = 10 days
P(t) = 537 × 2^(10/)
P(t) = 225.78 grams
Therefore, the amount of iodine-131 left after 10 days = 225.78 grams
