I belive the answer should be similar
George sold:

and Veronica sold:

As expanding the scientific notation numbers, we see that
George sold eight hundred thousand
Veronica sold 4 million
How many time is 4 million of 8 hundred thousand?
We simply divide!

So,
Veronica's song was downloaded 5 times the numebr of that of George.
B is the right answer.
Answer:
Hence final answer is $15.17
Step-by-step explanation:
Given that Dirk opened up a savings account with $600.
So P=$600
"At a yearly interest rate of 5 percent"
Means r=5% = 0.05
"compounded monthly" means n=12
i= monthly rate of interest = r/n=0.05/12
"how much interest will Dirk earn in six months." means find Interest when time is 6 months
Plug these values into compound interest formula:





A=615.169372966
which is approx
A=615.17
Now interest earned will be difference of A and P
Interest =A-P=615.17-600=$15.17
Hence final answer is $15.17
Yes, true because all rectangles have 4 sides with opposite sides that are parallel.
Answer:
45
Step-by-step explanation:
The mean is calculated as
mean = 
Given the mean of 8 numbers is 41 , then
= 41 ( multiply both sides by 8 )
sum of 8 numbers = 328
Given the mean of 2 numbers is 29 , then
= 29 ( multiply both sides by 2 )
sum of 2 numbers = 58
The sum of the remaining 6 numbers = 328 - 58 = 270 , so
mean =
= 45
The mean of the other 6 numbers = 45
