For this case we can apply the Pythagorean theorem to find "x". Taking the rectangle triangle of base 5 we have:

$x = \sqrt {11 ^ 2-5 ^ 2}\\x = \sqrt {121-25}\\x = \sqrt {96}\\\x = \sqrt {4 ^ 2 * 6}$

By definition of power properties we have:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

So:

$x = 4 \sqrt {6}$

Answer:

$x = 4 \sqrt {6}$

Using the formula c=2r, find the circumference with diameter of 28inches. Round your answer to the nearest inch.

Furkat [3]

Radius is equal to 1/2 the diameter. The radius is 14 (28/2=14)

With your formula:

c=2*14

c=28

HOWEVER I believe you meant

c=2(pi)r

In which

c=2(pi)14

c=28(pi)

In this instance for pi we can use 3.14 since we will be rounding anyway, so

c=28*3.14

c=87.92

Rounded to be

c=88

Note:

If we didn’t round pi out to 3.14 we would have gotten 87.964594...

A helicopter flies at a rate of 150 miles per hour. How many miles per second is this

den301095 [7]

Answer:

So,converting 150 mile per hour into miles per second we get 0.0416 miles per second

Step-by-step explanation:

Given:

Helicopter files at: 150 miles per hour

Required:

We need to convert 150 miles per hour to miles per second

Solution:

We know that, $1 \ mile\ per\ hour = \frac{1}{3600} \ miles\ per\ second$

So, 150 mile per hour will be: (We will be dividing 150 by 3600 to get miles per second)

$1 \ mile\ per\ hour = \frac{1}{3600} \ miles\ per\ second\\150 \ mile\ per\ hour = \frac{150}{3600} \ miles\ per\ second\\150 \ mile\ per\ hour = 0.0416 \ miles\ per\ second$

So,converting 150 mile per hour into miles per second we get 0.0416 miles per second
