Find a coordinates of the midpoint of the line segment with the given endpoints (7,4), (9,-1)

Answers

Answer:

Coordinates of midpoint are (8,1.5).

Step-by-step explanation:

Given coordinates of end points are;

(7,4) and (9,-1)

we can find the coordinates of mid-point,

[tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Here,

x1 = 7 and y1 = 4

x2 = 9 and y2 = -1

Putting these values in formula

Coordinates of mid point = [tex](\frac{7+9}{2},\frac{4+(-1)}{2})\\[/tex]

Midpoint = [tex](\frac{16}{2},\frac{4-1}{2})[/tex]

Midpoint = [tex](\frac{16}{2},\frac{3}{2})[/tex]

Midpoint = 8 , 1.5

Hence,

Coordinates of midpoint are (8,1.5).

Answers

Answer:

The coordinates of the midpoint are (5.55,4.655)

Step-by-step explanation:

Midpoint

The midpoint (xm,ym) of a segment defined by points (x1,y1) and (x2,y2) is calculated as follows:

[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]

[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]

We are given the points (5.1 , 5.71) and (6 , 3.6). The coordinates of the midpoint are:

[tex]\displaystyle x_m=\frac{5.1+6}{2}=\frac{11.1}{2}=5.55[/tex]

[tex]\displaystyle y_m=\frac{5.71+3.6}{2}=\frac{ 9.31}{2}=4.655[/tex]

Answer:

  C.  168°

Step-by-step explanation:

The exterior angle at any vertex of an n-gon will be ...

  360°/n

So a 30-gon will have exterior angles of ...

  360°/30 = 12°

The adjacent interior angle is supplementary to this, so is ...

  180° -12° = 168°

_____

Using the reasonableness test

You know that the interior angles of a square are 90°, and that regular polygons with more sides have larger interior angles. The most any regular polygon's interior angle can be is 180°. The only answer choice between 90° and 180° is the correct choice: 168°.

In the diagram, point X is the centroid. If
EX=8, what is the length of XC ?

Answers

Answer:

16

Step-by-step explanation:

If X is the centroid that means that EC is a median along with the other lines that intersect inside the triangle. Medians drawn from a triangle have a special rule; this rule is that all medians have a 2:1 ratio between the different sections of one median. For example, EC is one median with the two sections XC and EX. Therefore XC and EX have a 2:1, with the 2 representing the longer section closest to the vertex. This means that XC is double EX, so to find XC simply double EX measurement, which is 8. So XC must equal 16.

Juan bought a basketball for 40% off. If
he paid $36 for the basketball, what was
the original price?

Answers

Answer:

$24

Step-by-step explanation:

since 40% is in 100% i did 100 - 40 which i got 60

then it says that he paid $36 so I subtracted 60 - 36 and I got $24 as the answer iihope this helps! :)

100 - 40 = 60

60 - 36 = 24

The original price when he paid $36 for the basketball should be considered as the $24.

Calculation of the original price:

Since

Juan bought a basketball for 40% off And, If he paid $36 for the basketball.

So it be like

= 60% of $100 - $36
