Solve for t in terms of the other variables. <br> k= 3tm + rs
Lina20 [59]

Answer:

              t=\dfrac{k-rs}{3m}

Step-by-step explanation:

It's like solving any equation, except we have letters instead of numbers .

k = 3tm + rs           {subtract rs from both sides}

k - rs = 3tm            {divide both sides by (3m)}

\dfrac{k-rs}{3m}=t              {swap sides}

t=\dfrac{k-rs}{3m}            m≠0    

{m must be ≠0 because  you cannot divide by 0. There is no t for m=0}

What will the movement of a point which is on the surface of a circle touching the ground at the same time, if the circle turns
lesya692 [45]

Answer:

183.26cm

Step-by-step explanation:

Radius of the Circle = 50cm

Let the point be at A

It turns forward 210 degrees to B.

Therefore, the central angle subtended by the arc AB = 210 degrees

The movement of the point from A to B will be the length of the arc AB.

\text{Length of an arc }=\dfrac{\theta}{360} \times 2\pi r \\$Therefore, the distance moved forward$\\=\dfrac{210}{360} \times 2\times\pi \times 50\\\\=183.26$ cm
