One positive number is 5 times another number. The difference between the two numbers is 200, find the numbers.
Ilya [14]
X = 5y, where x > 0 and y > 0;
x - y = 200 => 5y - y = 200 => 4y = 200 => y = 200/4 => y = 50 => x = 250.

Ostrovityanka [42]
The square root of 29 is 5.3851

Compare the first number. In this case, both are five, so move on to the next number.

7 is greater than 3, so the answer would be 5.7145 > The square root of 29.

if i want the track to have a circumference of 400 feet what does the diameter of the track need to be?
natta225 [31]

Answer:

The diameter of the track needs to be 127.27 feet

Step-by-step explanation:

* Lets explain how to solve the problem

- The circumference of any circle is C = 2πr, where r is the radius

  of the circle and π is the constant ratio between the

  circumference and the diameter of the circle which

  approximately is 22/7 or 3.14

- The diameter of any circle is twice its radius

* <u><em>Lets solve the problem</em></u>

- The circumference of the track is 400 feet

∵ The circumference = 2πr

∵ π = 22/7

∴ 400 = 2 × 22/7 × r

∴ 400 = 44/7 r

- Divide both sides by 44/7 to find r

∴ r = 63.63

∵ The diameter of the circle = 2r

∵ The radius = 63.63 feet

∴ The diameter = 63.63 × 2 = 127.27 feet

* The diameter of the track needs to be 127.27 feet
