Answer:

B = 61.0

Step-by-step explanation:

Since this is a right angle, we can use trig functions

sin theta = opp side/ hypotenuse

sin B = 7/8

Take the inverse of each side

sin ^-1 ( sin B) = sin ^ -1 (7/8)

B =61.04497563

To the nearest tenth

B = 61.0

Should juveniles be punished less harshly than adults? Use "leniently" in your answer
vampirchik [111]
Juveniles should be punished less harshly than adults, but it depends on what they have done to earn their certain punishment. If they did something to a certain degree that deserves a harsh punishment then they shouldn’t be as leniently punished as a juvenile who didn’t do as much to deserve a harsh punishment.

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%
