Given:

The endpoints of a line segment QS are Q(-6,2) and S(5,6).

Point R divides the line segment QS in 1:2.

To find:

The coordinates of point R.

Solution:

Section formula: If a point divides a line segment in m:n, then the coordinates of that point are:

Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)

It is given that the endpoints of a line segment QS are Q(-6,2), S(5,6) and point R divides the line segment QS in 1:2. So, the coordinate of point R are:

R=\left(\dfrac{1(5)+2(-6)}{1+2},\dfrac{1(6)+2(2)}{1+2}\right)

R=\left(\dfrac{5-12}{3},\dfrac{6+4}{3}\right)

R=\left(\dfrac{-7}{3},\dfrac{10}{3}\right)

Therefore, the coordinates of point R are \left(\dfrac{-7}{3},\dfrac{10}{3}\right).

The scale of a room in a blueprint is 6in : 13ft. A wall in the same blueprint is 9 inches. How long is the actual wall?
Ganezh [65]

Answer:

Step-by-step explanation:

6 in to 13 ft = 9 in to x ft

6 / 13 = 9 / x.....cross multiply because this is a proportion

(6)(x) = (13)(9)

6x = 117

x = 117/6

x = 19.5 (or 19 1/2) ft <====
