6000lbs equal how many tons

ollegr [7]

This is quite simple...

1 ton has 2000 pounds.

so all you need to do is:

6000 / 2000 = 3

So, 6000 pounds equals 3 tons.

Answer:

152 degrees

Step-by-step explanation:

CF is a straight line, which means it equals 180 degrees. But FXE is an angle of 28 degrees so you subtract 180 from 28 to get 152 degrees.

(1+sint)/(cost)-(cost)/(1-sint)

Evgen [1.6K]

$\dfrac{1+\sin(t)}{\cos(t)} - \dfrac{\cos(t)}{1-\sin(t)}$

Multiply through the second term by $1+\sin(t)$ :

$\dfrac{1+\sin(t)}{\cos(t)} - \dfrac{\cos(t)}{1-\sin(t)}\cdot\dfrac{1+\sin(t)}{1+\sin(t)}$

$\dfrac{1+\sin(t)}{\cos(t)} - \dfrac{\cos(t)(1+\sin(t))}{1-\sin^2(t)}$

Recall that $\cos^2(x)+\sin^2(x)=1$ for all x :

$\dfrac{1+\sin(t)}{\cos(t)} - \dfrac{\cos(t)(1+\sin(t))}{\cos^2(t)}$

If $\cos(t)\neq0$ , we can cancel a factor of it in the second fraction.

$\dfrac{1+\sin(t)}{\cos(t)} - \dfrac{1+\sin(t)}{\cos(t)}$

and this simplifies to

$\dfrac{(1+\sin(t))-(1+\sin(t))}{\cos(t)} = \boxed{0}$
