Mathematics

Answer:

The circumference is tripled

Step-by-step explanation:

If the radius started as 2 the area would be 12.57 and the circumference would be 12.57.

Then if multiply the radius by 3 it would be 6 and the area would be 113.1 and the circumference would be 37.7.

12.57x3=37.7

Therefore the circumference triples when the radius is multiplied by 3.

Answer:

I think that both are true...

If it's one, it's the circumference.

Step-by-step explanation:

So say the radius is x.

The area is πx^2

The circumference is 2xπ

If you multiply it by 3:

The area is 3πx^2

The circumference is 6xπ

A video game system costs $185 and one video game costs $14.95. You can spend no more than $280 on the system and games. set up
disa [49]

Answer:

Therefore the maximum number of video games that we can purchase  

is 6.

Step-by-step explanation:

i) Let us say the number of video game system we can buy that costs $185

 is x and the number of video games of cost $14.95 is y.

ii) The total amount we can spend on the purchase of the video game

   system is $280.

iii) Now with the amount of $280 mentioned in ii) we can see that the

   number  of game systems that can be bought is 1.

 Therefore x = 1.

 Therefore the equation we can write to equate the number of video

  games  and video game system is given by $185 + $14.95 × y ≤ 280

  Therefore 14.95 × y ≤ 280 - 185 = 95

  Therefore y ≤   95 ÷ 14.95 = 6.355

  Therefore the maximum number of video games that we can purchase  

   is 6.
