Answer:
A
Step-by-step explanation:
9,460,528,400,000,000 can be rounded off to
9,000,000,000,000,000.
A trick you can use for these questions is count the number of zeroes at the end.
There are 15 zeroes, hence the answer is

Proof:


Hence, the number of zeroes is equal to the exponent.
The answer is 2x^2 to the question
Answer: The Answer would be 9.
Step-by-step explanation:
Since there is only 7 and the empty space is 2 cups, The answer would be 9. 7 + 2 = 9.
12+40+28+12= 92
40-12= 28
92+28= 120
28-12= 16
120+16= 136
P=136
Here are the steps to solving:
1) Write out problem 3.6+7.2k <25.2
2) Subtract 3.6 7.2k <21.6
3) Divide by 7.2 k <3
So k<3 would be your answer
