b. 65%
c. 55%
d. 45%

Answers

Answer 1
Answer: I cannot find a definition of oligopoly on line or anywhere else that specifies precise thresholds like what you are asking about. You will have to consult your own textbook. 
My guess would be A.
hopes this helps :) :D :)

What is the value of y?114Answer:

Answers

Answer:

value of y is, 57^(\circ)

Step-by-step explanation:

Exterior angle property of a triangle says that:

Sum of the two opposite interior angles.

From the given triangle:

Sum of two  opposite interior angles = y +y = 2y

Since, 114 degree is an exterior angle of a triangle,

By Exterior angle property of a triangle :

2y = 114

Divide both sides by 2 we have;

y = 57 degree

Therefore, the value of y is, 57^(\circ)

The opposite interior angles of the given triangle measure 57° each. So, the value of y is 57.

A triangle is one of the most basic geometric figures. It has 3 edges, 3 angles, and 3 vertices. The angle sum property of a triangle states that the sum of all three angles of a triangle is 180°. The property of triangles used in this question is that the sum of interior opposite angles measures the same as the exterior angle.

Since the sum of opposite interior angles is equal to the exterior angle, therefore in the given triangle,

114^o = y^o + y^o\n114^o = 2y^o\ny^o = (114^o)/(2) \ny^o = 57^o

Therefore, the value of y is 57.

In a crayon box there are 5 dark colors for every 8 light colors. If there are 20 dark colors, how many light colors are there?

Answers

5x4=20 so 8x4=32 32 light colors in the box
If we write this as a ratio then it would be 5:8. Now since there are 20 dark colors and also 5, what do 5 and 20 have in common... 5 times 4 is 20 so since we multiplied by 4 on dark colors do the same  to the light colors so 8 times 4 = 32. So the answer is 32 light colors

A building blueprint has a scale of 2 inches equal to 25 feet. on the blueprint, the 10 story building has a height of 12 inches what is the actual height of 1 story

Answers

Answer:

The actual height of 1 story is 15 feet.

Step-by-step explanation:

The given scale is

2 \ inches = 25 \ feet

We know the 10 story building has a height of 12 inches, but we need the actual height of 1, that is, the height of 1 story in feet.

Let's divide to find the number of inches per story

(12)/(10)=1.2

There are 1.2 inches per story.

Now, we know 2 \ inches = 25 \ feet, let's use the rule of three

x=1.2in(25ft)/(2in)= 15ft

Therefore, the actual height of 1 story is 15 feet.

2 inches: 25 feet.

1 inch:  25/2 feet

1 inch = 12.5 feet.


12 inches = 12.5 * 12 feet

                   = 150 feet.

The 12 inches height has an actual height of 150 feet.

The legs of an isosceles triangle have lengths x+1 and -x+7 . The base has length 3x-3. What is the length of the base? a. 6
b. 3
c. 4
d. cannot be determined

Answers


The only thing I'm a little unclear on here is what you mean by
the "legs" of an isosceles triangle. 

I'm going to assume that your isosceles triangle is standing on
the side you call the "base", and the "legs" are the two slanty ones,
standing up, which are the two equal sides.

With that set-up,                       x + 1 = -x + 7

Add  x  to each side:               2x + 1 =        7

Subtract  1  from each side:    2x      =        6

Divide each side by  2 :            x       =        3


Finally, if the base is  (3x - 3), then that's  (3·3 - 3)  =  6 .

Acellus inverse variation

Answers

The current when the resistance is 10 ohms is 24 amps

What are variations?

Variations are simply data that change in values (i.e. not constant)

Types of variation

The types of variations are:

  • Direct variation
  • Inverse variation
  • Joint variation
  • Combine variation

From the complete question (see attachment), we have the following highlights

  • The variation is an inverse variation
  • When current (I) is 30 amps, the resistance (R) is 8 ohms

An inverse variation is represented as:

k = IR

Where k represents the constant of variation.

The above equation can be rewritten as:

I_1R_1 = I_2R_2

So, we have:

30 * 8 = I_2R_2

240 = I_2R_2

When the resistance is 10 ohms, we have:

240 = I_2 * 10

Divide both sides by 10

24 = I_2

Rewrite the above equation as:

I_2 = 24

Hence, the current when the resistance is 10 ohms is 24 amps

Which of the following is equivalent to the expression below?(3) (4) (-3/4)

A. -12(-3/4)
B. -13(3/4)
C. -12- 3/4
D. -12 + 3/4​

Answers

The expression (3)(4)(-3/4) is equivalent to -9.

None of the given options is correct.

Given information:

The expression is (3) (4) (-3/4).

Multiplying 3, 4, and -3/4, we get:

(3)(4)(-3/4),

Simplify the parenthesis,

= 12(-3/4)

Multiplying,

= -36/4

Divide -36 by 4, and we get,

= -9

Therefore, the expression is equivalent to:-9
