What is the order of the linked genes r s and t if the distance between r and s is 22 mu the distance between s and t is 8 mu and the distance between r and t is 14 mu?
r-t-s
On a number line if r is less than s and if p is halfway between r and s and if t is halfway between p and r then what is the quotient of s minus t divided by t minus r?
The first half of the question yield two equations:1.I. p = r + (s - r) / 2II. t = r + (p - r) / 2The equation we are solving for, (s - t) / (t - r), does not have a p so we are going to Equation I for the pin Equation II. But first, to make things easier for us, let distribute the 2 in Equation II.2. 2t = 2r + p - r3. 2t = r + pSubstitute I4. 2t = r + r + (s - r) / 25. 2t = 2r + (s - r) / 2Again, lets distribute the 2, and combine the r's6. 4t = 4r + s - r7. 4t = 3r + sIn order to yield the desired quotient, we want a (s - t)on one side of the equation and (t - r) on the other. First let's get the (t - r) on the left.8. 4t - 3r = s9. t + 3t - 3r = s10. t + 3(t - r) = sNow move that extra t over to the right for the (s - t) we are looking for11. 3(t - r) = s - tNow divide both sides by (t - r) and we have our answer!12. 3 = (s - t) / (t - r)
S is between r and t the distance between r and t is 4 times the distance between s and t if rs equals 18 what is RT?
s - r = 18, so s = 18 + r: t - r = 4(t - s) is t - r = 4(t - 18 + r) ie t - r = 4t - 72 + 4r 3t = 72 - 5r Possible answers: t = 19, r = 3, rt = 16, st = 4; r/s/t = 0, 12, 16 x 1.5 gives 0, 18, 24 t = 14, r = 6, rt = 8, st = 2; r/s/t = 0, 6, 8 x 3 also gives 0, 18, 24 t = 9, r = 9 t = 4, r = 12 The last two are not in fact possible as t must exceed r. The distances starting from r at 0, are rs = 18, st = 6 and rt = 24 The above is unnecessarily complicated! If s is between r and t and rt is 4 times st then rs must be 3 times st. rs is 18 so st is 6 and rt 24. Simple!
What does R D T S represent?
It is an acronym for Range Digital Transmission System 1.732 S R of T to T D P? number where 3 lots added together = 3 lots multiplied together: R+R+R = RxRxR.
Rewrite R equals S plus 2T when S is 3 times as great as T?
R = S + 2T S = 3T .... substitute R = (3T) + 2T R = 5T
