The diagonal of a square can be obtained by the Pythagorean theorem and is given by:
 Diagonal = root (L ^ 2 + L ^ 2)
 Where,
 L: Sides of the squares
 Clearing L, we have:
 (Diagonal) ^ 2 = L ^ 2 + L ^ 2
 (Diagonal) ^ 2 = 2L ^ 2
 L ^ 2 = ((Diagonal) ^ 2) / 2
 L = (((Diagonal) ^ 2) / 2) ^ (1/2)
 Substituting
 L = (((24) ^ 2) / 2) ^ (1/2) = 16.97
 answer:
 The side of the playground is 16.97m long

Tom bought a PS4 on Black Friday for 25% off. If the system sells for $399, what is the sales price of the PS4?
Delicious77 [7]

Answer:

The sales price of the PS4 is $532.

Step-by-step explanation:

The system sells for $399 after giving 25% off on a Black Friday on the sales price.

Let the sales price of the PS4 system is $x.

Then after giving 25% discount the price will become x(1 - \frac{25}{100}) = 0.75x

Therefore, 0.75x = 399

⇒ x = 532  

Therefore, the sales price of the PS4 is $532. (Answer)

The propeller blades on a submarine have a radius of 6 feet. At full speed, they turn at 120 revolutions per minute. What is the
bogdanovich [222]

Using proportions, it is found that the angular velocity at the tip of the blade is of 753.98 radians per minute.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Each revolution has 2\pi radians, hence in one minute, the 120 revolutions will have a measure in radians of:

M = 120 x 2pi = 240pi = 753.98

Hence the angular velocity is of 753.98 radians per minute.

The numbers inside the parenthesis is the value of x, uses the equation associated with the value of x and solve.

H(1) Since 1 fits 1≤x≤3 use x^3

x^3 1^3 = 1

h(1) = 1

h(4) 4 fits x >3, so use 5

h(4) = 5
