You would subtract 11 on both sides of the equation.
Then multiply the reciprocal of 1/2 which is 2.
And you should get -16 as your answer <span />
Using cos addition formula:
use x for theta
cos(x+π/6)=cosx*cos(π/6)-sinx*sin(π/6)
sinx=1/4
cosx=√15/4
cos(π/6)=√3/2
sin(π/6)=1/2
cos(x+π/6)=(√15/4*√3/2)-(1/4*1/2)
cos(x+π/6)=(√45/8)-(1/8 )
cos(x+π/6)=(√45-1)/8)
Answer:
(suprisingly easy) 6x3x4=72 in.
Step-by-step explanation:
About 48 students are girls
Step - By - Step Explanation:
63 / 4 = 15.75
15.75 x 3 = 47.25
Because you can’t have 0.25 (1/4) of a person, you round to the next number.
Hope this helps!
Answer: 
Step-by-step explanation:
1. First, you must calculate the area of the football field. It is a rectangle, therefore, multiply the lenght by the width to calculate the area:
2. Then, divide this area by the area covered by a wheelbarrow full of dirt.
: number of wheelbarrows full of dirt needed for the field.
