Answer:
A
Step-by-step explanation:
We know million has 6 zeros.
So, 1 million would be written as:
1,000,000
Similarly, 27 million would be written as:
27,000,000
We know writing a number in scientific notation would make this a decimal in 1 decimal place, so we would select "2.7" as the base of the scientific number.
Now, how many places to the right do we need to go (in 2.7) to make it 27,000,000?
Counting, we see: 7 places
So, power of 10 would be "7", thus we can write:
Answer choice A is right

Answer:
-10.2n - 1
Step-by-step explanation:
We have two expressions in variable n and we have to add the two expressions.
An important thing to note is that only like terms can be added. i.e. the term with "n" can only be added or subtracted to the term with "n". Similarly a constant can only be added or subtracted to a constant.
Thus, the two given expressions add up to -10.2n - 1
Answer:
A person should work 32 hours to earn $384
Step-by-step explanation:
A worker's earring E are a function of the number of hour, H at a rate of 12/hr.
We need to write the function.
The function will be:
Earning is represented by E and Hour is represented by H
Now, How many hours would a person have to work to earn 384
We are given E=384, we need to find H
Putting values in above function and finding hours H
So, A person should work 32 hours to earn $384
