Answer:
well we need a map or a picture of what is hilighted in red
Assuming that your own ticket is already secured.
From the 5 friends you can only choose 3.
The order in which these friends are chosen is not relevant. So this is a Combination problem.
Where the order is relevant the problem becomes a Permutation problem!
So the answer is 5 combination 3. = ⁵C₃
⁵C₃ = (5 * 4 * 3) / ( 3 * 2 * 1) = 10
You can take 10 groups of any 3 of your 5 friends.

Answer:
114°
Step-by-step explanation:
Alternate exterior angles 1 and 7 are congruent. Angle 1 has the same measure as angle 7.
angle 1 = 114°
Answer:
<em>Explanation below</em>
Step-by-step explanation:
<u>Angles in a Triangle</u>
There are two basic relations of angles we need to recall:
- Supplementary angles add up to 180°
- Internal angles of a triangle add up to 180°
Note a, b, and c are the internal angles of the triangle. The angle c is what is needed to a+b to complete 180°, thus:
c = 180 - ( a + b )
Also, note c and d are supplementary angles. Again, c is what is needed to d to complete 180°, thus
c = 180 - d
From the two relations above, it follows that:
a + b = d
Answer:
<em>x > -9 OR x < -26 </em>
Step-by-step explanation:
there are <em>two</em> possible solutions.
solve absolute value: |0.2x+3.5| > 1.7
now its either 0.2x + 3.5 > 1.7 or 0.2x + 3.5 < -1.7
solution 1 : <em>x > -9</em>
0.2x + 3.5 > 1.7
subtract 3.5 from both sides, so you get
0.2x > -1.8
and then divide both sides by 0.2 or just .2 (theyre both the same thing)
and you end up with x > -9
solution 2 : <em>x < -26</em>
0.2x + 3.5 < -1.7
subtract 3.5 from both sides, get 0.2x < -5.2
divide both sides by 0.2 or .2
end up with x < -26
hope it helps and i did it right
