Answer:
She spent $33 dollars
Step-by-step explanation:
3 times 2.75 equals 8.25
4 times 5.50 equals 22
1 times 2.75 equals 2.75
8.25+22+2.75= $33
Answer:
15 pairwise comparisons; 30 pairwise rankings.
Step-by-step explanation:
Each of the 6 candidates can be ranked #1 in relation to the other 5, for a total of 30 pairwise rankings.
Of course, two of those are comparisons of the same pair of candidates. The same is true of all pairs of candiates, so the number of pairwise comparisons is half the possible number of rankings: 30/2 = 15.
_____
For example, for the pair of candidates A and B, you can have the two rankings ...
These cases are possible outcomes of the the one pairwise comparison ...
No. An obtuse triangle can not be an equilateral triangle because for a triangle to be equilateral, all three sides have to be the same measure and the same degree of angle (60). Since, an obtuse triangle has an angle greater than 90, the other two sides could be equal, but then you would have an obtuse isosceles triangle, not an equiangular equilateral triangle. Therefore, the obtuse angle in the obtuse triangle will limit the triangle from being an equilateral triangle.

Answer:
(64/5)π units²
Step-by-step explanation:
The area of this sector would be:
Given central angle
------------------------------ *(area of whole circle)
2π rad
In this case, the area of the sector is:
(8/5) π rad
------------------------------ * π(4 units)^2
2π rad
and this reduces to:
(4/5) * π*16 units² or (64/5)π units²
