Answer:the mass of the air inside the inflated balloon is 4 grams
Step-by-step explanation:
The initial mass of the balloon before it was inflated by the Math and Science class is 4 grams. After the balloon was inflated, the mass was 8 grams. This means that the mass by which the balloon increased would be the mass of the inflated balloon - the initial mass of the balloon. It becomes
8 - 4 = 4 grams.
Therefore, the mass of the air inside the inflated balloon is 4 grams.
Answer:
B. 70
Step-by-step explanation:
We have the sum given by
Now, we open the summation by substituting the values of 'i',
i.e. = (1+11) + (2+11) + (3+11) +(4+11) +(5+11)
i.e. = 12 + 13 + 14 + 15 + 16
i.e. = 70.
Hence, the sum of is 70.
So, option B is correct.
