Answer:
![(\frac{37}{11},\frac{77}{11} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B37%7D%7B11%7D%2C%5Cfrac%7B77%7D%7B11%7D%20%20%29)
Step-by-step explanation:
Given two points are (-1,7) and (7,7).
We are told to find a point which is in between them at a ratio of 6:5.
Formula for calculating a point at distance of ratio m:n is given by
![(\frac{mx2+nx1}{m+n} ,\frac{my2+ny1}{m+n} )](https://tex.z-dn.net/?f=%28%5Cfrac%7Bmx2%2Bnx1%7D%7Bm%2Bn%7D%20%2C%5Cfrac%7Bmy2%2Bny1%7D%7Bm%2Bn%7D%20%29)
where
are the inital and final points.
![(x1,y1)=(-1,7)\\\\(x2,y2)=(7,7)](https://tex.z-dn.net/?f=%28x1%2Cy1%29%3D%28-1%2C7%29%5C%5C%5C%5C%28x2%2Cy2%29%3D%287%2C7%29)
also m:n=6:5 ,
by substituting all the values we get,
![(\frac{6*7+5*-1}{11} ,\frac{6*7+5*7}{11} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B6%2A7%2B5%2A-1%7D%7B11%7D%20%2C%5Cfrac%7B6%2A7%2B5%2A7%7D%7B11%7D%20%29)
![(\frac{37}{11},\frac{77}{11} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B37%7D%7B11%7D%2C%5Cfrac%7B77%7D%7B11%7D%20%20%29)
Answer:
It wont load sorry maeby try putting the question again maeby it will work or is it my end.
Step-by-step explanation:
From what I learnt so far, there are 3 possible ways of finding whether ratios form a proportion
Answer:
840mi. - 12 hrs
x - 3 hrs
This is a simple cross multiplying problem.
840 _ 12
x -- 3 ⇒12x=3(840) ⇒ 4x=280 ⇒ x=70 miles
