If Ann can build the model in 3 hours, then in 1 hour she gets 1/3 of it done. Likewise, if Sam can build the model in 6 hours, then in 1 hour he gets 1/6 of it done. We are looking to find how long it takes when they combine their efforts, so we will add the two together and set it equal to 1/x, x being the number of hours it takes for both of them to get the whole job done. The equation then looks like this: 
. You will have to find the common denominator to add those fractions, and once you do, cross multiply to solve for x.
Y = cos(x)
sqrt(3)/2 = cos(30º)
dy = -sin(x)*dx
dy = -sin(30º)*(pi/180) = (1/2)*(pi/180)
y + dy = cos(x) - sin(x)dx
y + dy = sqrt(3)/2 - (1/2)*(pi/180) = 0.8573

Answer:
constant.
Step-by-step explanation:
like natural constants like pi or e.
Answer:
184,815
Step-by-step explanation:
so my answer my not be right so i would say double check but anyway just multiply 3333 and 555 and this should be your answer.
Tan(angle) = opposite leg / adjacent leg.
Tan(64) = x /30
x = 30 * tan(64)
x = 61.51
