The only plane shape in which every point on the figure is the exact same distance from the center is; The Circle

There are different types of plane shapes such as Square, rectangle, Circle, Trapezoid, Parallelogram, Rhombus, Kite, Triangle e.t.c.

Now, Except for the circle and Triangle, every other listed plane shape above is a quadrilateral because they have 4 sides. Now, no quadrilateral has all its' sides equal from the center. Likewise, no triangle has all its' sides equal from the center.

The only plane shape with all its' sides equal from the center is the circle because the radius is equal all through.

Answer:

29 degrees

Step-by-step explanation:

The interior angles of all triangles equals 180. We know already that we have 101 and 50 degrees. If we add that, we get 151. To find x, we have to simply subtract 151 from 180. If we do this, we get 29. x=29.

Answer: 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17

Step-by-step explanation:

First, we can ensure that 12 is the median by putting it in the middle and putting the same amount of numbers to its left and right side. To make the values have a mean of 12, the easy why to do it is to subtrate one as you move to the left and add one as you move to the right, that way they will cancel each other out and keep the mean at 12. The answer has a total of 11 values, has more than 3 values that are different, and has a mean and median of 12.

7+8+9+10+11+12+13+14+15+16+17=132

132/11=12

There are 5 values to each side of 12, making 12 the median.

The probability of getting first marble is red and the second

marble is blue is 4/15.

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes.

Given that:

Number of red marbles= 8

Number of blue marbles= 7

Total Number of marbles= 8+7 = 15 marbles.

P(red Marble) =[tex]\frac{8}{15}[/tex]

No replacement, now the total marbles = 14

P( blue marbles) = 7/14

Now, P( first marble is red and the second marble is blue.)

= 8/15*7/14

= 4/15

Hence, the probability of getting first marble is red and the second

marble is blue is 4/15.

I assume that you know what the question is asking to solve for.

The net profit margin for Korey's Comics is 42.5%.

Option A is the correct answer.

Profit is the difference between the selling price and the cost price.

We have,

Net profit margin is calculated by dividing net income by net sales and multiplying the result by 100 to get a percentage.

Net Profit Margin = (Net Income / Net Sales) x 100%

Substituting the given values.

Net Profit Margin = (1,850 / 4,350) x 100%

Net Profit Margin = 0.425 x 100%

Net Profit Margin = 42.5%

Therefore,

The net profit margin for Korey's Comics is 42.5%.

Explanation :

Then the recursive formula is :

Answer:

x = 17

Step-by-step explanation:

4x + 7 = 75         (as the 2 angles are interior alternate angles)

4x = 75 - 7 = 68

x = 68/4 = 17

Answer:

x = 17

Step-by-step explanation:

4x + 7 = 75         (as the 2 angles are interior alternate angles)

4x = 75 - 7 = 68

x = 68/4 = 17

Answer:

x = 10

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

6x-6 + 7x+1 +55 = 180

Combine like terms

13x+50=180

Subtract 50 from each side

13x+50-50=180-50

13x = 130

Divide by 13

13x/13 =130/13

x = 10

The answer is A!

From this, we will get the equation

(13x -5) + 55 = 180

+ 5 on both sides

13x + 55 = 185

-55 on both sides

13x = 130

Divide by 13 on both sides

x = 10
