Answer:

The answer is 75 degrees.

Step-by-step explanation:

The explanation is that the the supplementary angle to 80 is 100 since a straight line has an angle of 180, now the 100 degree angle is congruent to the angle x + 25 which means that x + 25 is equal to 100 so x is 75

400 people were surveyed about their eye color. 8% of the people surveyed have green eyes. how many people had green eyes​
VashaNatasha [74]

Answer:

32

Step-by-step explanation:

The problem above can be solved by using the <em>multiplication operation</em>.

Given: 400 people

           8% of the people with green eyes

Let's solve:

Let x be<em><u> the number of people with green eyes.</u></em>

x = 400 x 8%

x = 400 x (0.08)

x = 32

So, the number of people surveyed with green eyes is 32. The rest of the surveyed people (368) have a different eye color.

On a sheet of paper, you have 100 statements written down.
serg [7]

Answer:

50

Step-by-step explanation:

If the first statement its true (At most 0 of the statements are true), there are not true statements in the paper. So, the first statement its false.

Now, if the first statement its false, this mean there must be at least 1  true statement in the paper.

Now, if the second statement its true ( at most 1 of the statements are true) this implies that the third statement its true (if "at most 1" its true, then "as most 2" must be true).

If any statement (besides the first) its true, then all the statement that follows it must be true.

The first non false statement, then, must be the statement made by the person 51:  "At most 50 statements are true"

And the 49 statements that follows are true as well.
