Answer:

Step-by-step explanation:

8) a) No: of sides of a regular polygon = 360° / exterior angle

                                                                = 360°/18° = 20 sides

b) Sum of interior angles of regular polygon = (n-2) * 180°   {n-no:of sides}

                   = (20-2)*180° = 18*180° = 32400°

9) Let the exterior angle be x.

So, interior angle = 140° + x

Interior angle + exterior angle  = 180°

140° +x + x = 180°

140° +2x = 180°

2x = 180° - 140°

2x =40°

x = 40°/2 = 20°

Exterior angle = 20°

Interior angle  = 160°

No: of sides of a regular polygon = 360° / exterior angle

                                                                = 360°/20° = 18 sides

Hint: Always sum of exterior angles of regular polygon is 360°

A playstation 5 is $900 and costs $50 per game. A xbox is $400 and costs $60 per game. How many games will it take for both cons
belka [17]

Answer:

It would take a PlayStation 5 and 2 games to equal an Xbox and 10 games.

Step-by-step explanation:

I made a list that increase in the increments of the game price.

Something like this:

900—400~consoles alone

950—460~1 game

1000–520~2 games

1050—580~3 games

1100—640~4 games

1150—700~5 games

1200—760~6 games

1250—820~7 games

1300—880~8 games

1350—940~9 games

1400—1000~10 games

Left side is PlayStation 5 and right side is Xbox. The first row is the price of the consoles alone and then each row after that is the price of the console with an additional game. As you can see, the third row down on the left, the PlayStation 5 with 2 games is $1,000. If you look at the eleventh row on the right, you can see that Xbox with 10 games is also $1,000

Kyle asked a random group of students what their favorite sport was. The results are below. Boys Girls Basketball 10 8 Football
Ronch [10]

Answer:

The probability that Kyle will pick a girl who likes football is 12.5%.

Step-by-step explanation:

The data provided is as follows:

                         Boys        Girls       Total

Basketball          10             8             18

 Football           25             7             32

  Soccer             9             19             28

 Baseball           18            22            40

   Total               62           56            118

Compute the probability that Kyle will pick a girl who likes football as follows:

P(F|G)=\frac{n(G\cap F)}{n(G)}

            =\frac{7}{56}\\\\=0.125\\\\=12.5\%

Thus, the probability that Kyle will pick a girl who likes football is 12.5%.

What is the quotient of 5 divided by 2 1/2 reduced to the lowest terms
bixtya [17]
When you divide with fractions you have to multiply the "dividend" with the reciprocal of the "divisor". 

2 1/2 in improper fraction is 5/2 

5 x 2/5 = 10/5 = 2
