Javed downloaded from the internet two files that had a combined size of 696 megabytes. the size of the first file was 290 megabytes, and it took 5 minutes to download. assuming that the files downloaded at a constant speed, how long did it take for the second file to download?

Time taken to download second file = 7 minutes.

Step-by-step explanation:

Javed downloaded from the Internet two files that had a combined size of 696 megabytes. The size of the first file was 290 megabytes.and it took 5 minutes to download.

Total size of file downloaded = 696 megabytes

Size of first file  = 290 megabytes

Size of second file  = 696 - 290 = 406 megabytes

Time taken to download first file = 5 minutes.

Time taken to download second file = 7 minutes.

x = 12

y = 15

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
