Answer:

A: 1 and 7

Step-by-step explanation:

when 2 angles are put next to each other on a straight line with a line going through the middle those two angles always add to 180 since 180 is equal to a straight line.

supplementary angles are 2 angles that together make 180.

out of the options given, all of them except 1 and 7 are equal angles and as a result would not add to 180. if you put angles 1 and 7 on a straight line together, they do, thus the answer is A, aka 1 and 7.

Answer:

1 and 7

Step-by-step explanation:

supplementary means that they add up to 180º

1,3 5,6 1,7

2,4 7,8 2,8

1,2 5,7 3,5

3,4 6,8 4,6

There are still some more but my hands are tired of typing.

Step-by-step explanation:

So, in this problem, we're given the size of the of the file. We are also given the rate of change of the amount-downloaded function.

Notice how the transfer rate is in units of time (25.2 MB/s means 25.2 MB per second).

If we want to calculate how long it'll take to download the entire file, we have to divide the file size by the amount of the MB downloaded in one second. (This is assuming the download rate is constant, in the case it isn't constant, you would use calculus) This will find the total number of seconds needed to download the entire file.

We're essentially solving for t in the equation

$400.6 = 25.2t$
