" 12."(2m+5)/(3)=3m-10

Solve the following eqations.Check your result in each case (2m+5)=3m-10

When a ball bounces,it rises to (2)/(3) of the height from which it fell.If the ball is dropped from a height of 36m ,how high will it rise at the third bounce? 10(1)/(3)m(b)10(2)/(3)m(c)12(1)/(3)m (d) 12(2)/(3)m

The shadow of a stick 5m long is 2m. At the same time the shadow of a tree 12.5m high is (i)3m (ii)3.5m (iii)4.5m (iv)5m

30. If the roots of the equation 12 x^2 + mx + 5 = 0 are in the ratio 3:2, then m can be (B) 12 (C) 5 10 (D) .10. 12 12

Suggest a distance corresponding to each of the following order of length : (i) 10^7m (ii) 10^4m (iii) 10^3m (iv) 10^2m (v) 10^(-3)m (vi) 10^(-6)m (vii) 10^(-14)m

If the points (-1,-1,2), (2,m,5) and (3,11,6) are collinear, then find the value of m.

If the points (-1,-1,2),(2,m,5) and (3,11,6) are collinear, find the value of m.

If the points (-1,-1,2) ,(2,m,5) and (3,11,6) are co-linear then find the value of m.

If the points (-1,-1,2), (2,m,5) and (3,11,6) are collinear, find the value of m.
