What is the answer? And show how you got it .
Lubov Fominskaja [6]
First, let's find out how much the 6 boxes weigh. If one box of clay weighs 17.4 ounces, then how much does 6 boxes weigh? Well, let's multiply. 

                                17.4 × 6 = 104.4

Next, let's find out how much clay each student get. Since there are 18 students and only 6 boxes, let's find this out by dividing the ounces.

                                      104.4 ÷ 18 = 5.8

So, each student gets 5.8 ounces of clay. I hope this helps!

g the value of tan(-150) is because -150 is in quadrant the reference angle is and the exact value of tan (-150) is
never [62]

Answer:

<h3>  1/√3</h3>

Step-by-step explanation:

Given the expression tan (-150), from trigonometry identity, tan(-θ) = -tanθ

Hence  tan (-150) = - tan 150

First is to find the value of tan 150.

tan 150 = tan (180-30)

tan (A+B) = (tan180 - tan30)/1+tan180tan30

tan (180-30) = (0 - 1/√3)/1+0(1/√3)

tan (180-30) =  -1/√3/1

tan (180-30) =  -1/√3

Since tan 150 =   -1/√3

-tan 150 = -(- 1/√3)

-tan 150 =   1/√3

Since -tan 150 = tan (-150) =  1/√3

Hence the exact value of tan (-150) is   1/√3
