There are 3 points on the plane.Explain or determine whether point C is closer to point A or point B.

Answers

Point C us closer to point B because if you connected the points B would be in the middle of C going to A line.

Step-by-step explanation:

I hope I helped!

The perpendicular line from a point to a line is the shortest distance from the point to the line

With regards to the three points on the plane, point C is closer to point B

The reason point C is closer to point B is as follows:

The known parameter is;

Three points, A, B, and C, are located on a plane

Required:

To explain or determine whether point C is closer to point A or point B

Method:

Define, the relationship between the destination points A, and B

Find the shortest distance from point C, to the definition of points A, and B

Solution:

The relationship between points A, and B is that they form the line segment AB

The shortest distance from a point C to a line segment AB in Euclidean geometry is the  perpendicular distance from the point C to the line segment AB

The line which best approximates the perpendicular line and therefore,

shortest distance from C to AB is the line segment CB

CB represents the shortest line and therefore distance from C to AB, that is

CB is shorter than line segment CA and which shows that it is shorter to go

from C to B, than from C to A or point C is closer to point B than point A

Karen bought cupcakes for her sister's birthday party. 3 cupcakes had sprinkles on top. The other 27 cupcakes did not have sprinkles. What percentage of the cupcakes had sprinkles?

Answers

Answer:

10%

Step-by-step explanation:

so

3 cupcakes had sprinkles

27 didn't have sprinkles

which means that there are a total of 30 cupcakes, (because 3 + 27 is 30)

so then set up a proportion

part/whole = percent/one hundred

substitute in the given values

3 / 30= precent/100

simplify

1/10 = precent/100

you don't have to use cross products here because it is pretty obvious that 10 * 10 = 100 so then just multiply 1/10 by 10 and you get your answer

percent = 10

The base angles of a isosceles triangle are equal

3x-11 = 2x+11

Subtract 2x from each side

3x-2x -11 = 2x-2x+11

x-11 = 11

Add 11 to each side

x-11+11 = 11+11

x = 22

The sum of all the angles in a triangle is 180

3x -11 + 2x+11 + 2y = 180

Combine like terms

5x +2y = 180

5*22 + 2y = 180

110 + 2y = 180

Subtract 110 from each side

110+2y-110 = 180-110

2y = 70

Divide by 2

2y/2 =70/2

y = 35

Parallel to y=-3x+4, x-intercept at 4

Answers

Answer:

y = -3x + 12

Step-by-step explanation:

The slope of parallel line is the same as the original line.

If the x-intercept is 4, this as a point can be stated as (4, 0)

We can now solve for the y-intercept.

y = -3x + b

0 = -3(4) + b

0 = -12 + b

12 = b

Put everything we solved for back into the formula [ y = mx + b ]

y = -3x + 12
