Answer: 84.8°

Step-by-step explanation:

a²+b²+c²-2bc(cosA)

cosA = b² + c² - a² / 2bc

That is the formula we will be using.

Then, plug in our numbers.

cosP= 500² + 380² - 600² / 2(500)(380)

cosP= 34400/380000

cosP≈ 0.09052631

cos⁻¹(0.09052631) ≈ 84.81

∠P = 84.8°

An office has 150 employees, and 30 of the employees work the night shift. What percentage of the employees work the night shift
Zanzabum
<h2>Answer:</h2>

The percent of employees who work in the night shift are:

                                     20%

<h2>Step-by-step explanation:</h2>

Total number of employee in the office are: 150

Number of employee who work in the night shift are:  30

The percent of the employee who work in the night shift is calculated as follows:

\dfrac{\text{Number\ of\ people\ working\ in\ the\ night\ shift}}{\text{Total\ number\ of\ employees}}\times 100

Hence, on putting the value in the above formula we get:

=\dfrac{30}{150}\times 100\\\\\\=\dfrac{1}{5}\times 100\\\\\\=20\%

            Hence, the answer is:

                          20%

IDK how to do this who else does
Nezavi [6.7K]

Answer:

36 ft²

Step-by-step explanation:

Scale factor means the side length are multiplied by some value.  Here, Jack takes 4 feet and multiplies it by a value of 1 1/2.  

The side length he wants is one and a half times the length of his neighbor's.  

The 'one' means the side length you started with, and the 'one half' means add half to the original length.

one and a half of four is six.  (4 plus half of 4, which is 2, so 4 plus 2)

The box is square, so each side is 6 ft, so the area of the box is 6x6 = 36 ft²
