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

= $60 - $36

= $24

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

Find the midpoint of the line segment with the given endpoints. (5.1,5.71) and (6,3.6).

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]

The coordinates of the midpoint are (5.55,4.655)

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°.
