Option C is the statement that best describes a problem that occurs when the majority criterion is observed. This is because the majority criterion is a single-winner system.

It is given that all the options except option C are true about the majority criterion.

Option C - "The majority criterion must be used for first place, second place, third place, and so on to be valid" is not correct because this criterion is used only for choosing the first place.

Answer:

  a = 80°

Step-by-step explanation:

In order to solve this figure, we need to find a useful relationship between the various angles. We can use the straight angle at the upper left vertex of the equilateral triangle.

__

The sum of angles there is ...

  a + 60° +(a/2) = 180°

  3/2a = 120° . . . . . . . . . . subtract 60°, collect terms

  a = 80° . . . . . . . . multiply by 2/3

_____

Additional comment

All triangles are isosceles, because they all have 2 (or more) sides the same length. That means the base angles are half the supplement of the a.pex angle. Of course, adjacent vertices of a rhombus have supplementary angles.

Answer:

x = 0.75 :: y = 1.5

Parenthesis

Exponents

Mulitplication/Division (depending on which one comes first - starting from left to right)

Addition/Subtraction (depending on which one comes first - starting from left to right)

A)

3 x (5 + 1) = 3 + (5 x 1) <== parenthesis first

3(6) = 3 + 5 <== multiply and add

18 = 8

False

B)

whenever you see this kind of question you don't need to start doing all the expressions, but look at the first and last numbers of the answer, the ones that cannot be changed (have no x or y or have those that cannot be changed in this expression):

the answer can't be a or c because in the given expression we can find 3x²y² and that's the only number where we can find x²y², so it cannot be changed. (you'll have 3x²y² in the answer)

now let's look at the last digit, that doesn't have a x or a y:

in b and d we can find 2 different results so this can determine which answer is correct:

let's look back at the given expression: -7+4= -3

so the answer is b

Answer:

No.

Step-by-step explanation:

The triangles aren't congruent because the value of C is unsaid.

The numbers that the product is 26 and one of the numbers is one larger than six times the other number are 2 and 13.

The product of two numbers is 26.

let the two numbers be x and y.

Therefore,

xy = 26

One of the numbers is one larger than six times the other number. Therefore,

x = 1 + 6y

Hence,

xy = 26

(1 + 6y)y = 26

y + 6y² = 26

6y² + y - 26 = 0

using quadratic formula,

[tex]\frac{-b + \sqrt{b^{2} -4ac } }{2a}[/tex]

where

a = 6

b = 1

c = - 26

Therefore,

y = 2 or - 13 / 6

We can only use the positive value.

Hence,

2x = 26

x = 26 / 2

x = 13

By definition, the distance between two points is always positive, so the correct option is D.

Let's say that our plane has rectangular coordinates, so it would be something like a xy-plane.

Each point has 2 coordinates, so we can write:

A = (x₁, y₁)

B = (x₂, y₂)

The distance between the points is given by:

[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

As you can see, the distance is defined as positive (indifferent of the coordinates of the points).

Step-by-step explanation:

If t represents the time in minutes each person is working after Sheila arrives, then the number of parts produced is ...

  Eric: 156 +12t

  Sheila: 15t

These values are equal when ...

  156t +12t = 15t . . . . . Eric's part count is equal to Sheila's part count

  156 = 3t . . . . subtract 12t

  52 = t . . . . divide by 3

Sheila will catch up to Joe after 52 minutes.

879,000 square feet  is the lateral surface area of the pyramid

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The lateral surface area of a square pyramid can be calculated using the formula L = (1/2)Pl

where P is the perimeter of the base and l is the slant height of the pyramid.

Since the base of the pyramid is a square, the perimeter is 4 times the length of one side, or 4 × 750 = 3000 feet.

To find the slant height, we can use the Pythagorean theorem with one leg equal to half the length of the base (375 feet) and the other leg equal to the height (450 feet):

l =√375² + (450)²

= 583.095 feet

Therefore, the lateral surface area is:

L = (1/2) × 3000 × 583.095

= 879,000 square feet

Hence,879,000 square feet  is the lateral surface area of the pyramid
