Yes. If we wanted to divide 104 by 8 we could write 104 as sum of multiples of 8 with which we are familiar:
104=80+24
then
We use the same procedure to divide the given number by 8:
First We can "decompose" the number as a sum of multiples of 8 which we recognize easily. Then, divide each single one of them with 8.
That is

now decompose 265,822,784:
265,822,784=240,000,000+24,000,000+1,000,000+800,000+22,784
now decompose 22,784
22,784=16,000+6,784
decompose 6,784
6,784=6,400+384= 6,400+320+64
Thus:

Answer:
C
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = , then
sin30° = =
=
( cross- multiply )
2x = 10 ( divide both sides by 2 )
x = 5 → C
Answer: In 2005 the amount spend on internet ads = $74.6 billions.
In 2009 spending on internet search ads will reach $102 billion .
Step-by-step explanation:
Given : The number of internet paid search ads is increasing as advertisers move away from traditional marketing methods.
The equation can be used to project spending on internet search ads, in billions of dollars, x years after 2000.
To estimate spending on internet ads in 2005.
We need to put x= 5 in the above equation [∵2005-2000=5]
i.e. In 2005 the amount spend on internet ads = $74.6 billions.
Put y= 102 in the given equation, we get
[Subtract 40.1 from both sides]
And 2000+9=2009 [x is the number of years after 2000]
Hence, in 2009 spending on internet search ads will reach $102 billion .
