Short answer A
This one is exactly the same (with number changes) as the last one. You cannot use t which is in time, to mix with pure numbers which in this case is grams. That means that both C and D are incorrect.

Now as with the last one, are you going to raise e to a minus number or a plus number? Remember that if e is raised to a plus number, the sample in this case will increase. You are watching a radioactive decay. The number has to be smaller. So B is eliminated. There is only one answer left and that's A. It should be correct.

Is 0.7142857.... a rational number? why or why not?
Andreyy89
The number 0.7142857 is definitely a rational number. This number can also be expressed as 7142857/10000000. Now we know that a rational number is a number that can be expressed as a fraction or a quotient of two integers. The denominator of the fraction can never be equal to zero. In case of the number given we can clearly see that the denominator of this fraction is not zero. The actual fraction of this number is 5/7. In this case we find that the denominator is not zero.

Please help I dont get it​
SpyIntel [72]

Answer:

B. 12cm

Step-by-step explanation:

We can double check by plugging in the number. However, the question trys to trick you, by giving you the diametre, but in order for the formula to work (V=4 /3πr^3), we will divide the diametre by 2 (12 ÷ 2= 6),

--------------------------------------------------------------------------------------------------------------

Once we do that, we can double check, when you plug in your numbers your answer will be around 900 (904.78, to be exact, but the question asks for approximate diamtetre).

----------------------------------------------------------------------------------------------------------------

Have a good day :)
