Remember that pi=180, 
so 180/6=30, 30*5=150,
what's tan 150? 
Remember that 150 degrees is in the 2nd quadrant, and this is tangent, so it means the answer must be negative, because tan 150= - tan 30, and -tan30=-√3/3. 

Answer: -√3/3.

A toy company had an order of five boxes to ship unfortunately this was 17 pounds over the shipping weight limit per order of ea
pochemuha

Answer:

28 pounds

Step-by-step explanation:

We have a total of 5 boxes, now we know that each box weighs 9 pounds, therefore:

Total weight = 5 * 9 = 45 pounds

Which means there are 45 pounds in total.

We are told that the limit is exceeded by 17 pounds. To find the limit weight, it is necessary to subtract the total weight and the excess:

45-17 = 28 pounds

Therefore, the maximum weight allowed per shipment is 28 pounds.

A line with a slope of -1/3 passes through the point (9,3). What is its equation in point-slope form?
amm1812

The point-slope form:

y-y_1=m(x-x_1)

We have:

(9,\ 3)\to x_1=9,\ y_1=3\\\\m=-\dfrac{1}{3}

Substitute

y-3=-\dfrac{1}{3}(x-9)

A conical paper cup has a radius of 2 inches. Approximate, to the nearest degree, the angle β so that the cone will have a volum
dezoksy [38]
Volume = area of base *height 

20 = pir^2 *h

20 = 3,14*4*h

h = 20/12,56 = 1,59 rounded 1,6

- using the triangle formed by radius,the height of cup and the slant height of cup so we can writing that

tan ß = h/r so tan ß = 1,6/2 = 0,8

tan ß = 0,8 so ß = arctan 0,8 = 38,6 degrees so 39 degrees
