30 tens = 30 x 10 = 300
300 ones = 300 x 1 = 300
300 is your answer
30 tens = 30 x 10 = 300
3 hundreds = 3 x 100 = 300
3 is your answer

Answer:
   D:  2/4
Step-by-step explanation:
Usually when we talk about a point partitioning a segment, we are interested in the ratio of the first segment to the second:
   BC : CD = 2 : 2 = 1 : 1
Since this is not an answer choice, we need to "reverse engineer" the answer list to see if we can find an answer that corresponds to a reasonable interpretation of the question.
__
None of the segments is 3 units long, so neither of answer choices A or B makes any sense.
While segment BD is 4 units long, there is no segment that is 1 unit long, so answer choice C makes no sense, either.
There are segments that are 2 units long and a segment that is 4 units long, so if we interpret the question to be "what is the ratio of BC to BD?" then answer choice D is appropriate.
 
        
             
        
        
        
Answer:
- Initial amount of the material is 67 kg
- Hal-life is 83 hours
<u>The required equation is:</u>
- m(x) = 67 *  , where m- remaining amount of the radioactive material, x - number of hours , where m- remaining amount of the radioactive material, x - number of hours
<u>After 5 hours the material remains:</u>
- m(5) = 67 *  = 64.260 (rounded) = 64.260 (rounded)
 
        
             
        
        
        
Answer:
It is about 537.2
Step-by-step explanation:
V= π · r^2 · h
V= π · 3^2 · 19
V≈ 537.2
 
        
             
        
        
        
Answer:
A) Associative Property of Addition
Step-by-step explanation:
<u><em>Associative Property of Addition</em></u>
Let A, B and C  be any three real numbers
A+(B+C) = (A+B) + C
Given data
(20.4 + 3.75) + 4.25 =  20.4 + (3.75 + 4.25)
                                  =  20.4 + 8.0
                                 =  28.4
