Look at question #8. q: about how many songs can he download in 2 hours

We are told that 1,024 kilobytes (kB) is equal to 1 megabyte (MB).

We are also told that Timothy's computer downloads at a rate of 256 kB per second. So let's convert this to MB:

So now we know Timothy's download rate is 0.25 MB per second.

We know there are 60 seconds in a minute, so to find how many MB can be downloaded in a minute, we must multiply by 60:

So in 1 minute, Timothy can download 15 MB worth of songs. But to find the amount in 1 hour, we must multiply by 60 again:

So in 1 hour, Timothy can download 900 MB worth of songs. However the question asks for two hours; so we multiply by 2:

In 2 hours, Timothy can download 1,800 MB worth of songs. We are told a typical song is 4 MB, so let's divide by 4:

So now we know that Timothy can download B) 450 songs in 2 hours.

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
