NeX [460]

Answer:

2.4 days

Step-by-step explanation:

Time working together,t ,is

1/t = 1/a+ 1/b  where a and b is the times working alone

1/t = 1/4 + 1/6

Multiply each side by 12t to clear the fractions

12t( 1/t )= 12t(1/4 + 1/6)

12 = 3t+2t

12 = 5t

Divide by 5

12/5 = 5t/5

Convert 14° into radians manually (no calculator) please show work. Thank you in advance!!
Inessa [10]

1 degree is \dfrac\pi{180} radians. So 14 degrees is \dfrac{14\pi}{180}=\dfrac{7\pi}{90} rad.

Easy way to remember this: one complete revolution in a circle is 360 degrees. But it's also 2\pi radians. So the conversion rate is

\dfrac{2\pi\,\rm rad}{360^\circ}=\dfrac{\pi\,\rm rad}{180^\circ}

i.e. for every \pi radians there are 180º.
